         Expanding
         Our Horizons
         In 2023, we continued our journey to strengthen our international position and solidify our domestic leadership. The Oman acquisition
         and the Corridor PSC extension both provide a platform for further upside and greater value to shareholders. We expanded our energy
         transition commitment with the development of the Ijen geothermal project and made good progress on our Solar PV projects. The
         Amman Mineral Internasional (AMMN-IDX) Initial Public Offering was also extremely successful1.


         Our dedication to environmental, social and governance initiatives and commitment to sustainability are well recognised by
         international ESG rating agencies. To maintain this trajectory, we continue to set ourselves challenging targets to improve operational
         excellence, safety and financial performance and our community contribution, in order to position MedcoEnergi as a leading
         sustainable energy company and one of Southeast Asia’s largest independent energy companies.

         In 2023, we continued to translate our climate aspirations into

                                We actively monitored public reports regarding claims of odours in Block A in 2023 and prioritized strong engagements with all stakeholders
                                before and during operational activities. We maintained open communication with the public, government agencies, and civil society
                                organisations to ensure transparency and collaboration. This engagement enabled us to respond swiftly to all such reports.

                                After careful investigation, these claims were found to be unsubstantiated with no evidence; the air quality parameters were within safe and
                                permitted thresholds.

Grievances                      We will continue to regularly and thoroughly monitor air quality and implement thorough HSE readiness procedures wherever we operate
                                as part of our commitment to ensure public health.

      We are also aware of the recently issued Taskforce on Nature-related Financial Disclosures (TNFD) framework which has
      developed a set of disclosure recommendations and guidance that enable businesses and financial institutions to assess,
      report, and act on their nature-related dependencies, impacts, risks, and opportunities. We are currently exploring the
      framework to understand the recommendations of TNFD.

 Our Tier-1 and Tier-2 material topics have been translated into 104 goals and key performance indicators (KPIs) in year 2023 as part of
 our 2023-2027 Sustainability Roadmap. This roadmap is aligned with MedcoEnergi’s sustainability objectives and climate aspirations,
 which incorporate contributions from the Board of Directors (BoD), functions and subsidiaries. These KPIs serve as the basis for our
 action plans, which are detailed at the conclusion of each chapter in this Sustainability Report.


 By the end of 2023 we achieved 86% of our 2023 sustainability goals and KPIs derived from the 2022 materiality assessment. The
 2023 goals we have yet to achieve will be carried forward for completion in 2024.

         Human Rights Policy
         As we expand our horizons, MedcoEnergi acknowledges that our business growth inherently exposes us to various risks that may
         impact the human rights of individuals. We identified Human Rights as a key material topic during our initial materiality assessment
         in 2018 and reaffirmed it as a Tier 1 topic while revisiting it in 2022.


         Our commitment to respect human rights has always been integrated into various aspects of our business and reflected in our
         policies such as the Sustainability Policy, Code of Conduct, Community Development and Security policies, as well as our Corporate
         Recruitment Guidelines. Additionally, we have a comprehensive grievance and whistleblowing system to effectively address any
         concerns related to human rights.


         Following the corporate-level human rights assessment in 2022, we established MedcoEnergi’s Human Rights Policy in early 2024.
         This policy builds upon existing human rights-related policies and best practices at MedcoEnergi into a standalone corporate policy.
         Developing this policy involved extensive consultations with representatives from our external and internal stakeholders, including the
         representatives from Medco Oil & Gas and Power assets, Heads of Division and labour unions to ensure comprehensive perspectives.
         The policy received formal approval from our Board and was officially signed off in January 2024.


         Our standalone Human Rights Policy encompasses the following key aspects:


         • The commitment to respect human rights as outlined in the Universal Declaration of Human Rights (UDHR), International Labour
            Organization (ILO) Declaration, and other relevant instruments.
         • Guidance was provided by the United Nations Guiding Principles on Business and Human Rights (UNGPs), the Voluntary Principles
            on Security and Human Rights (VPSHR), and the International Finance Corporation (IFC) Performance Standards.
         • Adherence to applicable laws in the countries where we operate.
         • Implementation of robust risk management policies and procedures: these include all policies related to our Code of Conduct,
            Code of Supplier, Sustainability, Health, Safety & Environmental, Community Development and Security.
         • Protection of the human rights of our employees, communities, and business partners. This includes, among others, fair working
            conditions, recognition of rights to unionise and bargain collectively, and zero tolerance for child labour, modern slavery, harassment,
            and discrimination.
         • Identification and mitigation of potential risks faced by vulnerable groups, including minorities, women, children, and migrant
            workers.
         • Requirements for business partners to adhere to our Code of Conduct and Code of Supplier, which ensure legal compliance and
            protection of employee rights.
         • The use of grievance and whistleblowing mechanisms to address impacts of company activities, with procedures to investigate
            and remedy.
         • Governance and oversight through involving the Board of Commissioners, Board of Directors, Corporate Sustainability and Risk
            Management Division, and all functional teams.

 Contractor Employee Ethics Awareness
 A&IC Division, in collaboration with HR and Digital Information Technology (DIT), held a virtual Contractor Employee Ethics Awareness
 Training on 29 November 2023. This session is part of A&IC’s educational efforts to underscore our commitment to ethics. The
 training was attended by 669 oil & gas Indonesian contractor employees. It aimed to raise awareness about associated risks, such as
 undue influence and conflicts of interest, and to address the challenges of a digital work environment.


 Annual Statement of Adherence (SoA) and
 Conflict of Interest (CoI) Deterrence
 MedcoEnergi manages conflicts of interest by requiring employees to submit Statements of Adherence (SoA) and Conflict of Interest
 (CoI) declarations which we review and monitor their completions annually. Assurance tests in SoA were expanded in 2023 to cover
 personal data privacy, human rights, political involvement, and anti-money laundering awareness. We received 97.57% or 2,534
 submissions for SoA from permanent employees of Medco Oil & Gas and 99.89% or 900 submissions from permanent employees
 of Medco Power in 2023.1 In total, we received 5,733 SoA submissions from permanent employees and third party contractors in
 Medco Oil & Gas and Medco Power in 2023. However, the limited assurance process, at the moment, only covers the permanent
 employees. The results indicated employees’ thorough understanding of Our Code and related policies. We also received 5,8552 CoI
 submissions as part of annual CoI declaration process. The CoI submissions helped us evaluate and mitigate risks across ten categories,
 enabling us to enhance our campaign programmes. We also conducted pilot project of 2023 CoI declaration for Contractor Services
 in Corridor. Please refer to page 68.

         Detection
         MedcoEnergi has established a fraud detection programme to flag unusual patterns in financial transactions, employee behaviour,
         and other assets that may indicate fraudulent activities. This programme includes fraud detection procedures, such as data analysis,
         transaction monitoring, and monitoring of both employees and third-parties. The Company has also implemented systems to detect
         and report misconduct against its Our Code, allowing for appropriate action to be taken by the relevant parties.



         MedcoEnergi Internal Ethics Hotline
         Our employees have access to an internal hotline for any compliance-related enquiries and an external hotline for reporting fraud
         and concerns regarding misconduct.




                                                                 Internal Ethics Hotline

         Most inquiries on our internal hotline in 2023 were requests for guidance on conflicts of interest, gifts and entertainment, legal
         compliance, and anti-corruption policies.


         We observed a decline in the number of inquiries received in 2023. It corresponded with an increase in our communication and
         training, particularly classroom training sessions and Fraud Risk Assessment workshops. These trainings enabled us to directly address
         inquiries during the sessions.

 Third Party Risk Management Programmes
 Engaging Third Parties
 MedcoEnergi proactively communicates with business partners as part of our third-party risk and compliance management.

 We reviewed the programme and adopted risk-based approaches to establish long-term action plans that enhance our Corporate
 Third-Party Compliance programmes between 2023-2027. In 2023, we also familiarised the Code of Suppliers to our oil & gas
 domestic and international vendors, including in Thailand and Oman.

         Our Third Party Compliance Programme
         Meeting the Know-Your-Customers (KYC) Requirements from Our Partners
         KYC is a due diligence process used by our buyers and lenders to assess and mitigate third-party risks. At MedcoEnergi, we do not
         only undergo the KYC process but also apply it to evaluate our partners. In 2023, our A&IC Division, along with Marine Operations,
         Corporate Finance and Treasury, and SCM, conducted KYC efforts to ensure we meet all KYC inquiries thoroughly. These efforts
         addressed anti-corruption, business ethics, human rights, sanction compliances, and anti-money laundering topics.


         Third-Party Risk Detection Initiatives
         Our initiatives maintain business transparency and stakeholder trust in our governance with third parties.


         Anti-Bribery and Corruption (ABC), Contract Compliance, and Internal Control Vendor Audit
         MedcoEnergi carries out three types of vendor audits: ABC, Contract Compliance, and Internal Control Vendor Audits. We completed
         22 ABC Vendor Audits, including at our Bualuang asset in Thailand. In 2023, our Internal Control Vendor Audit identified compliance
         risks, assessed contract compliance, and enhanced operational and business controls. We evaluated the internal controls of selected
         vendors at the corporate level and within our domestic oil and gas assets, with plans to extend these audits to our international assets
         in the future.

 Strengthening Our Third Party Compliance Programmes
 We implemented several initiatives in 2023 to strengthen our third-party compliance programmes:
 1. Vendor Compliance Survey in Oman: We conducted a compliance survey for a select group of vendors in Oman, targeting 20 high-
     risk and local community contractors. The survey focused on key topics related to the Anti-Bribery Management System (ABMS).
 2. CoI Declaration for Contractor Services in Corridor: We broadened the CoI declaration process for service contractors in the Corridor
     Asset using a Microsoft platform, achieving a 100% completion rate with 2,152 submissions.
 3. Joint Vendor Audit with HSE: For the first time, we carried out a joint vendor audit with the HSE team for Bualuang.

         Responses
         We are committed to adhering strictly to Our Code, enforcing a Zero Tolerance policy against bribery, corruption, fraud, and other
         ethical violations. Validated claims will result in immediate remedial actions.


         Ethics and Compliance Working Group
         We examined all allegation reports and implemented corrective measures. We determined the appropriate disciplinary actions that
         complied with our procedures for addressing allegation reports. These procedures involved a thorough review process by the Ethics
         and Compliance Working Group, consisting of the Board of Directors (BoD) level, the Head of Corporate A&IC, HR, Legal and other
         relevant function as necessary. This collaborative approach ensures an objective and fair process for making impartial, uniform, and
         equitable resolutions. This working group will effectively become the Ethics and Compliance Committee in 2024.


         Incidents Disclosures
         We received 63 reports of alleged violations through whistleblowing channels in 2023, a decrease from the 73 reports received in
         20221. These reports covered a wide range of concerns, including counterfeiting, intellectual property rights, theft, inappropriate use
         of assets, procurement frauds, and other fraudulent activities.


         The actions taken in 2023 involved imposing appropriate sanctions on 45 individuals, including employees, contractors, and business
         partners. These ranged from verbal warnings and reprimand letters to formal written warnings and terminations of employment.


         In addition to imposing disciplinary actions, we have also implemented a Person Checking System. This system was introduced to
         prevent hiring employees with poor integrity records. It will serve as a critical component in our employee recruitment process.

 Monitoring and Evaluations
 Monitoring and evaluating our responses to claims or reports help us measure how effective our actions are. This in turn enhances the
 transparency and accountability of our corporate governance.



 Anti-Bribery Management System (ABMS)
 ABMS is designed to detect, prevent and respond to bribery and corruption. We have continuously enhanced it since its inception in
 2018.

 We achieved two ISO 37001 ABMS recertifications for this reporting year for Procure-to-Pay (P2P) oil & gas domestic assets, which
 included expansions to Sampang, Madura Offshore, and Bangkanai, and the Medco Power head office.

 Our ISO 37001 ABMS progressed well with the following milestones:
 • 2nd surveillance for South Natuna Sea Block B, JOB Tomori, and Power assets (MEB/DEB, ELB, and TJBPS);
 • 1st surveillance for Bualuang asset in Thailand;
 • Completed audits and expanded certification to our Corridor asset.


 Further details on our corporate-level ABMS journey can be accessed here.


 ABMS Implementations in the Corridor Asset
 Our Journey
 We are steadfastly committed to maintaining the highest ethical standards as we apply our GCG principles across our operations,
 irrespective of location. As a result, in 2023, our Corridor asset obtained the ISO 37001 ABMS Certification.

 2023 Youth Integrity Workshop At Corridor
 As part of the Corridor ISO 37001 ABMS implementation, we launched our first Youth Integrity Programme at Medco Oil & Gas,
 themed “Empowering Future Leaders.” The event was attended by 112 participants from 19 prominent universities in Palembang,
 all of whom are scholarship recipients from Corridor, and engaged in an interactive workshop. They deepened their understanding
 of corruption, ethics, integrity, explored MedcoEnergi’s ESG initiatives, discussed social management systems, professional
 competencies, and compliance-related professions.




                                                                           2023 Youth Integrity Programme in Palembang, Indonesia




 Continuous Improvement
 We shall continuously update our standards, policies and initiatives in line with MedcoEnergi’s expanding portfolio. These also provide
 feedback mechanism to the organisation on room for improvements.

         Harassment – Free Workplace (HFW)
         We are dedicated to fostering a harassment-free workplace, as outlined in our Code and communicated throughout the organisation.
         We reviewed Minister of Manpower Decree No. 88 Year 2023 concerning Sexual Harassment Prevention and Mitigation Guidelines
         and conducted a thorough analysis, benchmarking against industry standards to enhance our workplace environment.

         We are also developing comprehensive programmes such as awareness campaigns, reporting channels, task forces, and guidelines,
         which are to be launched in 2024. Our commitments extend beyond mere compliance with laws: we strive to create a culture where
         everyone feels respected and can thrive.




         Personal Data Protection Act (PDPA)
         We are actively preparing for upcoming regulatory changes, including the Indonesia Personal Data Protection (PDP) Law No. 27 Year
         2022, which is set to be enacted in October 2024. We began assessing our readiness for compliance, evaluating policies, procedures,
         and systems. We conducted two half-day workshops in August 2023 with our HR Function to identify strengths and areas for
         improvement in safeguarding personal data.

         We plan to extend this assessment to our Digital Information Technology, Supply Chain Management, Relations & Security and other
         relevant functions in 2024.

         Transparency in
         Payment to Government
         Interactions with the government exposes us to potential ethical risks since we are heavily regulated. We therefore believe that
         transparency is essential to not only maintain trust and accountability, but also promote fair competition and mitigate ethical risks.
         Our approach includes:
         • Comprehensive system reporting and documentation: accurately recording all transactions, including gifts, entertainment, and
             facilities provided to government officials, with standardized processes to simplify the process across our operations.
         • Strict compliance with laws: adhering to Indonesia’s anti-corruption laws and international regulations governing financial
             transactions with government bodies.
         • Employee education and awareness: educating employees at all levels about the importance of transparency, conducting regular
             training to ensure compliance with laws, company policies, and best practices.


         Our commitment to transparency in payment to government is also demonstrated by our contribution to Indonesia’s Extractive
         Industry Transparency Initiative1 (EITI). The latest Report from Indonesia can be accessed here.




         Anti-Corruption
         Collective Actions
         MedcoEnergi’s anti-corruption efforts include partnerships with the stakeholders to foster integrity in the industry. These collective
         actions are important because they allow us to work together to build an anti-corruption culture that could otherwise not be done by
         an individual company.
         • Engagements with the Indonesian Petroleum Association Ethics and Compliance Committee (IPA ECC)
         • Contributions to local anti-corruption initiatives
         • Joint anti-corruption efforts with international organisations


         In 2023, we participated in the several anti-corruption events, including the ones below.
         • IPA ECC and Pertamina University held a lecture on “Achieving Business Sustainability through Personal Integrity” in March 2023




                                                                                    IPA ECC and Pertamina University held a general lecture with a theme of

 • MedcoEnergi and BP shared integrity-building strategies in a knowledge-sharing session with Petronas in November 2023.
 • We joined the Indonesian Oil and Gas Auditor Forum (Forum Auditor Migas Indonesia/FAMI) Summit in Bali on September 2023
     to discuss the following:
     • Governance, Risk, and Compliance (GRC) transformations;
     • IT audits and their roles in digital security;
     • Integrated frameworks for fraud prevention, detection, and investigation;
     • Cyberattacks.



 Youth Integrity – Taking Actions
 Following its Youth Integrity Workshop, our Corridor asset held a competition from October to November 2023 involving 14 college
 students. This event was conducted as part of the International Anti-Corruption Day. This competition further supported these
 university students’ efforts to promote integrity in public service while combating corruption and promoting social justice.

 After the event, these students were motivated to raise awareness about corruption, collaborate with universities and government
 institutions, advocate transparency and policy reforms, and monitor public funds, all while upholding their own integrity. These
 students will be key contributors to creating a more equitable, transparent, and thriving society. We also believe that the anti-
 corruption culture should be developed from an early age.

         Our Bualuang asset conducted training for 70 students from the Ban Pak Nam Chumphon School. This training promoted children’s
         rights and aimed to reduce school bullying. It was followed by an educational trip to the Chumphon Marine Learning Centre. Our
         efforts sought to instil a culture of respect for human rights and foster ethical education from an early age. This initiative is part of our
         commitment to adopt best practices for communicating human rights within communities.

 Since 2021 our oil and gas projects have been consistently and thoroughly evaluated through our sustainability assessments, within the

 Some of the environmental protection initiatives that have broader impacts on local communities are explained in Chapter 8.




                                     Restatement of Water, Waste and Biodiversity Data

 • The restatements in oil & gas assets include non-hazardous waste data for 2021-2022 to improve our data disclosures;
 • Water withdrawals in 2021-2022 included produced water, cooling water, and water for operations; and
 • Revegetation beyond regulatory requirements in 2022 excluded reclamation activities by Corridor and disclosed that as separate
     data.


 Meanwhile, the non-hazardous waste data for Medco Power in 2021-2022 were restated due to changes in the waste conversion
 factors. Medco Power’s water withdrawals in 2022 were also restated to improve data disclosures.

  Composting Organic Waste
  We transport generated organic waste in our operational area to
  our Waste Treatment Centres (WTCs) to be sorted, weighed, and
  composted. The remaining waste that cannot be composted is
  sent to the nearest landfills.


  Block A and Rimau diverted 3.9 and 6.1 tonnes of waste from
  disposal through composting in 2023. Tarakan composted 0.5
  tonnes of waste through the Waste Industrial Park (Taman Industri
  Sampah Kegiatan Ekonomi Berbasis Pengelolaan Lingkungan/TIS-
  KEBAL), as part of its long-standing CSR programme with the
  local authorities. Our Corridor asset has a practice in place of
  composting organic waste in three of its nurseries: Keri, Grissik
  and Suban Camps.

 Awareness Campaigns

 We implemented multiple programmes to reduce our hazardous
 waste. They include the Mercury Guard Bed (MGB) catalyst
 optimisation programme in Belanak3; the quality-based lube
 oil replacement in South Natuna Sea Block B4; the replacement
 of fluorescent lights with LED lights5; and the replacement
 of batteries to rechargeable ones6. We also raised awareness
 among our workforce through campaign posters to ensure the
 safety of both our people and the environment.

 1        Hazardous waste is waste containing substance, energy and/or components which, due to their properties, concentration and/or amount, may directly or indirectly pollute and/or damage
          the environment and/or harm the health of humans or other living creatures’ lives in the areas or waste designated ‘hazardous’ or some similar term under the applicable regulatory
          requirements of the country where MedcoEnergi operates.
 2 All our hazardous waste is managed by a third party. Not all waste generated is managed within the same reporting year; the waste managed in any given year may include
   carryovers from the previous year. In other words, waste generated in one year might be stored temporarily and then delivered to a third party in the following reporting year.
   These approaches account for the discrepancies between the amounts of waste generated and the waste directed for disposal in any given year.		
   There might be a difference of one in total numbers due to rounding up of decimals.						
 3 The MGB catalyst optimisation includes regulating the temperature of the MGB to prevent the rapid condensation and saturation of the catalyst.
 4 The aim of the replacement is to reduce the generation of waste lubricating oil since 2010 until now. We replace the lubricating oil based on the results of laboratory analyses of the
   lubricants – not based on the running hours of machines and equipment.
 5 The light replacements took place in South Sumatra Block, Corridor, and Sampang.
 6 The battery replacements occurred in South Sumatra Block, Lematang, and Sampang.

 Managing our Wastewater

 Across most of our assets, domestic wastewater is treated at our Waste Water Treatment Plants (WWTPs). We regularly monitor
 effluents to ensure compliance with regulations mandated by the Ministry of Environment and Forestry (MoEF) and maintain levels
 lower than the Threshold Limit Value (TLV) before discharging. In 2023, our oil & gas assets discharged 18,534 megalitres of wastewater,
 a decrease from the previous year. This reduction is proportional to the decline in water withdrawal compared to 2022.


 Our power assets discharged 380 megalitres of treated wastewater into water bodies during the same year, showing an increase from

         Water Risk Management

         We conducted a qualitative assessment of risks related to water resources management in most of our assets in 2021. The aim was to
         prevent issues concerning water scarcity, coastal floods and inland floods in neighbouring communities. Subsequently, we carried out
         further assessments in 2023 to update our findings. The results showed that the company is not currently at risk of facing significant
         impacts in any scenario across all assessed operations. According to the WRI Aqueduct tool, none of our operations in 2023 are in
         water-stressed areas.

         Tree and Mangrove Planting Initiatives
         We planted trees and mangroves across our assets in 2023 to promote biodiversity in land and coastal areas, aligning with SKK Migas’
         national tree-planting campaigns.

         The South Natuna Sea Block B contributes to biodiversity conservation through ecosystem rehabilitations of both mangroves and
         coral reefs using artificial reefs. In addition, the Sampang asset participated in land rehabilitation efforts through planting Acacia
         mangium trees in Taddan Village and beach casuarina trees in Tambak Lekok Village.



         Medco & I - Two Trees
         Medco & I - Two Trees is our initiative that encourages employees to plant or adopt at least two trees. This programme ran from
         September to November 2023 across all MedcoEnergi operational areas in Indonesia. Our employees participated by individually
         planting trees or adopting them through the Medco Foundation, with the option of choosing between perennial trees or mangrove
         plantations.


         This programme aims to engage employees to take concrete actions to combat climate change, which aligns with MedcoEnergi’s Net

 Establishing Our Climate Interim Targets
 MedcoEnergi’s climate aspirations were developed by reviewing our host government’s Nationally Determined Contributions (NDCs),
 analysing internal Long-Term Planning (LTP) data, and conducting peer benchmarking. We also considered climate-related risks and
 opportunities, past and ongoing emissions reduction efforts, and energy efficiency programmes. Additionally, we factored in existing
 and emerging regulatory trends in host countries.


 Our interim targets are to reduce Scope 1 and Scope 2 GHG emissions by 20% and 30%, and methane emissions by 25% and 37%
 for our oil and gas business by 2025 and 2030 respectively by using 2019 as the base year. We chose 2019 as it represents our
 normal operations before the pandemic, making it the most relevant reference point as the base year. Furthermore, we aim to have
 26% of our installed capacity from renewable energy by 2025 and 30% by 2030 for our power business1. This target-setting process
 was collaborative, incorporating both top-down and bottom-up approaches that involved various divisions at all levels.

 Our climate interim targets provide the framework for MedcoEnergi’s climate actions. They enable us to track and report quantifiable
 progress towards reducing our emissions and achieving our climate aspirations.


 Enhancing Our Employees’ Capacity for Climate Action
 Our key progress in 2023 was our capacity-building programme for climate action. We conducted several trainings involving our
 employees, management members, and suppliers. Our capability-building programme has multiple approaches that are also
 integrated with programmes from various divisions. They are:
 1. Business Leaders’ Programmes
           These are external programmes in sustainability, ESG and climate change certifications by various credible universities and
           institutions such as University of Cambridge, Yale University and competent boards:
           • Sustainability and ESG Programme for Business Leaders
           • Climate and Biodiversity Programme for Business Leaders




 1         The Government of Indonesia has a target of achieving at least 23% new and renewable energy installed capacity in 2025 and at least 31% by 2050, which is stipulated in the country’s
           Enhanced National Determined Contribution (ENDC) issued in September 2022.

         2. Focus Group Programmes
            • Climate specific training: climate risks and opportunities, carbon accounting, technologies and best practices for GHG
              management, carbon removal and offsets, carbon pricing and carbon taxes, green financial instruments, and carbon markets.
                 - Ten training modules for our “Climate Change and Energy Transition Working Groups” at fundamental, intermediate, and
                    focused levels in January-February 2023. Further information about this training can be found on page 178-179, along with
                    other training on energy transitions and technological awareness.
                 - Training on climate risks for our Board of Directors and management members to prepare them for the Climate Change
                    Risk Assessments (CCRA) in August 2023. During this training, these topics were discussed: the latest updates on climate
                    science, climate commitments of our host countries, climate requirements from the Equator Principles 4 (EP4), and our
                    CCRA roadmap.
                 - Carbon Market Workshop for senior leaders and Climate Change & Energy Transition working groups in November 2023.
                    The workshops provided insightful information on how the carbon markets were developed in Indonesia. Amongst the
                    topics they covered: carbon pricing, credits scheme implementation, Measurement Reporting and Verification (MRV), etc.
            • Climate topics integrated into existing programmes: Inductions for New Hires, Medco 101 for New Leaders, Finance and
              Accounting Apprentice Programme (FAAP), Subsurface Academy, and others.

         3. Workforce Capability Development Programmes
            • E-learning modules covered sustainability and climate change fundamental topics for senior leaders and the Climate Change &
              Energy Transition Working Group.
                 - E-training courses were held for our employees between November and December 2023. These self-paced courses
                    consisted of three modules that delved into the sustainability frameworks, understanding climate change, and corporate
                    Climate Change Strategy. The target participants were senior leaders and climate change and members of the transition
                    working groups. We plan to expand this training to all our 2,000 employees.
            • Lunch-and-Learn Seminars related to climate change issues.

         4. Supply Chain Partners Programmes
            Vendor Day: highlighted key initiatives in our Climate Change Strategy, including the initiative for Scope 3 GHG emissions, to raise
            our business partners’ awareness.


         Participating in Global and Regional Climate Events and Conferences
         MedcoEnergi took part in several climate-related events and conferences in 2023. During these gatherings, we presented our
         Sustainability Framework and Climate Change Strategy and highlighted the critical role of the energy sector in combating climate
         change. Our participation in these events and conferences allowed us to gather valuable insights and feedback regarding our strategies,
         progress, and performance. This is part of the collaboration and engagement efforts in our Climate Change Strategy.

         Establishing Climate-related Incentives
         MedcoEnergi has adopted incentive-based compensation schemes linked to sustainability and climate efforts, particularly those that
         reduce GHG and methane emissions and expand renewable energy capacities. Each year, Team Performance Contracts (TPCs) are
         created for various levels of staff, from top executives to individual employees. These contracts include specific Key Performance
         Indicators (KPIs) related to sustainability and climate, which are reviewed quarterly. At the end of the year, achievements against these
         targets are evaluated to determine performance incentives, potentially including salary adjustments.

 Our Journey in
 Climate Business Integration
 We incorporate considerations of climate change into our business operations and are dedicated to upholding the transparency of
 our progress. We received a B rating in the 2023 CDP Climate Change, consistent with our score from 2022. We also released our
 inaugural Taskforce on Climate-Related Financial Disclosures (TCFD) report in 2022. The complete TCFD report is available at this
 link.


 We strive to continuously improve our climate-related reporting in accordance with the latest standards for climate disclosures. The
 TCFD has fulfilled its remit and was disbanded in October 2023. Subsequently, the International Financial Reporting Standards (IFRS)
 Foundation has taken over the provision of climate disclosure standards that continue the work of the TCFD. We have begun to align
 our transparency efforts regarding climate change with the IFRS’s S1 Sustainability-related Financial Disclosure and S2 Climate-
 related Disclosure standards within this section.


 Below is an update of our climate action progress, guided by the disclosure requirements of IFRS S2:

         Assessing Our Climate-related
         Risks and Opportunities
         Managing our climate-related risks and opportunities effectively is critical to maintaining our business resilience. This is why in 2021
         we conducted an initial qualitative climate scenario analysis to identify and assess transitions and both physical risks and opportunities
         that may potentially impact our Company. Further reading on the approaches, methodologies, findings, and mitigation measures for
         our 2021 climate scenario analysis can be found in our TCFD report here.


         In 2023, we completed the deeper review in a CCRA for physical risks in two assets (Block A and JOB Tomori) and are currently in-
         progress for the transition risks.



         Quantifying Our Climate-Related Risks and
         Opportunities
         Quantifying the impact of our climate-related risks and opportunities is the next step that we are taking to effectively manage,
         mitigate and adapt to climate change. These steps will enable us to comprehensively understand the potential impact of climate
         change on our operations, finances, and long-term business sustainability.


         MedcoEnergi has conducted a more detailed climate scenario analysis that updated the 2023 qualitative analysis and undertook
         a more quantitative approach. This pilot analysis focused on Block A and the non-operated asset, JOB Tomori. These assets were
         selected to enhance our understanding and implementation of the CCRA requirements under Equator Principle 4 (EP4).


         We used the latest climate scenarios issued by the IPCC, the Share Socioeconomic Pathways (SSPs)1. Our analysis was based on
         the SSP1-2.6 low emissions scenario and the SSP5-8.5 high emissions scenario for 2030 and 2050 timeframes respectively. These
         scenarios and timeframes were chosen to offer a broader range of temperature changes for physical risk assessments and align with
         the preferences of national climate analyses.


         The exercise has provided us with comprehansive findings from the physical risk assessments. Meanwhile, our assessments of
         transition risks are still ongoing at the time of publishing this Sustainability Report.


         Screening-level physical risks assessment
         We conducted a screening-level physical risks assessment for 20 material assets under two Intergovernmental Panel on Climate
         Change (IPCC) scenarios for 2030 and 2050. This assessment employed the Climate Impact Platform (CIP) tool2, which used climate
         data and projections generated by its built-in global climate models. This desk-based assessment focused on:




         1   The SSPs are a set of scenarios used in climate modelling to explore how different societal and economic factors could influence future GHG emissions and the resulting climate impacts.
             Unlike the previously used RCPs, the SSPs consider a range of socioeconomic assumptions such as population growth, economic development, energy use and technological progress
         2 CIP Tool is an industry-leading global climate database for screening-level physical risk assessments. It pulls from a database of detailed knowledge on the vulnerabilities of different
           asset types and a range of climate projections to rapidly assess exposure of an asset(s) to physical climate risks that arise from different climate hazards.

 Key Findings
 • Extreme heat stands out as the hazard with the highest risk scores and the most significant increases in risks across all climate
      scenarios and timeframes.
 • Water scarcity, inland floods (river flooding) and coastal floods exhibit the highest baseline risks, whereas extreme heat is identified
      to be the most common climate hazard across the 20 assets.
 • Extreme heat, water scarcity and wildfires show the most substantial increases in risk scores for both the 2030 and 2050
      timeframes under the SSP1-2.6 and SSP5-8.5 scenarios.
 Two climate hazards were selected for Block A and JOB Tomori following the screening-level assessments. These selections were
 based on their high absolute risk1 scores, indicating significant exposure and/or relevance to the assets in both the baseline and future
 climate projections.


 Quantitative Physical Risk Assessments
 We subsequently conducted quantitative physical risk assessments to examine and quantify the potential financial impacts of the
 two selected climate hazards on these assets given the climate data and projections used in the CIP tool. For these assessments, the
 following quantification approaches were used:


                                          Block A                                                                                      JOB Tomori

                         Extreme Heat:                                                                                    Extreme Heat:

                         requirements set by the MoEF.                                                                    increase cooling capacity.


                         Inland Floods (Extreme Rainfall):                                                                Coastal Floods:
                         Revenue loss due to business disruption caused                                                   Revenue loss due to business disruption caused

                         transport.


 Key Findings for Block A
 Extreme Heat:
 • Global climate projections show minimal likelihood of daily max temperatures exceeding 39°C in 2030 and 2050.
 • Block A’s design is resilient to mitigate extreme heat projections and there are no financial impacts anticipated on its operations.


 Inland Floods (Extreme Rainfall):
 • Global climate projections predict flood for maximum three-day disruptions at condensate trucking route accesses.
 • Nevertheless, Block A has two condensate storage tanks, allowing for approximately ten days of holding time. In addition,
      accelerating post-flood condensate trucking to meet the cumulative nomination targets can eliminate this financial impact.

         Key Findings for JOB Tomori
         Extreme Heat:
         • Climate projections forecast a maximum daily temperature of 35.37°C.
         • The current asset design is resilient to temperatures up to 38°C at installed capacities, and global projections indicate no likelihood
            of temperatures exceeding this in 2030 and 2050. As such, there are no financial impacts on its operations.


         Coastal Floods:
         • Global climate projections forecast a 0.22 m sea-level rise, with a total sea level rise amounting to 1.92 m when combined with the
            highest recorded tide in 2020.
         • At JOB Tomori, the jetty infrastructure is deemed resilient to the projected sea-level rises, standing at approximately 5.2 m above
            sea level. As such, the anticipated sea-level rises are expected to disrupt condensate lifting cargo activities in a limited way and
            there are no financial impacts on its operations.
         In summary, Block A and JOB Tomori are not expected to suffer financial impacts from the selected Climate Hazards. This is accounted
         for by the existing facilities in both assets, which are considered resilient enough to overcome the projected impacts from physical
         climate risks.



         Quantitative Transition Risk Assessments
         The governments of the countries where we operate have started to lay the groundwork in establishing a carbon pricing mechanism.
         In Indonesia, Presidential Regulation 98/2021 on Implementation of Carbon Pricing for Target Achievement sets the foundation
         to establish a domestic carbon market that involves carbon trading and results-based payment. Furthermore, Law 7/2021 enacts
         the carbon tax amount of USD 2.06/tCO2e with the initial stage of implementation limited to the coal power plants in 2022 and
         will be expanded to the other sectors in 2025. There is also the Ministry of Environment & Forestry Regulation 21/2022 concerning
         Procedure For Implementation of Carbon Pricing that regulates carbon trading & carbon tax. However, the implementing guidelines
         for the oil & gas sector have yet to be in place. The most recent one is the Financial Services Authority Regulation 14/2023 that puts
         into effect carbon trading through Carbon Exchange by Indonesia Stock Exchange (IDX). In relation with the latter regulation, Medco
         Power has registered as an issuer with IDX and is working towards selling carbon credits through Carbon Exchange in the future.

         Meanwhile, Thailand is currently formalising their carbon pricing mechanisms, which will be regulated under the Climate Change Act
         (Climate Change Law). This law is undergoing a public hearing from February to April 2024 and is expected to be approved by the
         Thailand cabinet in June 2024.

         While our quantitative transition risk assessments are still ongoing, we have examined the potential impact of carbon pricing on our
         business using our assured 2023 GHG emissions data.

         Given the uncertainty of implementation of regulation, we calculated potential financial impacts conservatively as a worst-case
         scenario approach by applying our gross operational control approach. It covers all oil & gas and power assets, both domestic and
         international, based on our best available information. The potential financial impact of carbon pricing on our business may reach up
         to USD 11.7 million, as per our 2023 GHG emissions.

 Emissions
 Reductions
 ‘Emissions Reductions’ are initiatives that aim to reduce emissions from our operations and supply chains and improve our energy and
 resource efficiency. Additionally, under this pillar, we also aim to explore nature-based solutions for carbon sequestration.



 GHG Emissions Performance
 We continue to manage, monitor, and disclose our Scope 1 and Scope 2 GHG emissions. We are currently improving our internal
 systems and processes to disclose our Scope 3 GHG emissions. We aim to disclose our assured Scope 3 GHG emissions and their
 interim targets in 2025.

 We ensure that our standardised Air and GHG Emissions Calculation Tool complies with the latest updates to laws and regulations and

 We account for direct emissions from our oil & gas and power assets as part of our Scope 1 GHG emissions. The two largest sources
 of these emissions are the combustion and flaring of natural gas in our operations. We are supporting government’s programme on
 eliminating routine flaring by 2030.


 Oil & Gas
 In 2023, our absolute Scope 1 GHG emissions2 from our oil & gas assets were 4,223,200 tCO2e. This is a 2.8% decrease from the
 previous year due to operational improvements, GHG emissions reduction projects, and natural production decline.

 This table provides a breakdown of our Scope 1 GHG emissions in tCO2e and their sources:

 The decrease of Scope 1 GHG emissions is due to operational improvements (e.g. fuel optimisation, and both flaring and venting
 reduction projects) and natural production decline. For further information on the trend and statistics of this Scope 1 GHG emissions
 data, please refer to the 2023 GRI Performance Data.

         Power
         For our power business, our absolute Scope 1 GHG emissions in 2023 were 1,416,625 tCO2e, indicating a 3.8% increase from 1,365,141
         tCO2e in 20221. This increase is primarily due to the rise in electricity production, which led to increases in the consumption of natural
         gas and Scope 1 GHG emissions.

         Indirect GHG Emissions (Scope 2)
         Our Scope 2 GHG emissions are our indirect GHG emissions associated with our purchased electricity.


         Oil & Gas
         In 2023, our oil & gas assets emitted 26,354 tCO2e of Scope 2 GHG emissions, indicating an 8% increase from 24,390 tCO2e in 20222.
         Part of this increase came from our 2023 switch to grid power in the South Sumatra Block, Bangkanai and Oman assets.


         Power
         Our power assets’ Scope 2 GHG emissions were 1,566 tCO2e in 2023, indicating an 11% decrease from 1,760 tCO2e in 20223. This is
         due to fewer unplanned outages at operational assets followed by decreases in imported electricity and Scope 2 GHG emissions.



         1   The assets in 2022 and 2023 that produced Scope 1 GHG emissions are ELB, EPE, MPE, MEB, DEB, MRPR, BJI, PPP and MPI Head Office.
         2 The list of assets in 2023 that consume energy from purchased electricity consist of Bangkanai, South Sumatra Block, Tarakan, South Natuna Sea Block B, Sampang, Thailand, Oman,
           Singapore Office, Jakarta Office, Palembang Office and Corridor. Meanwhile, the list in 2022 is similar, but the Malaysia Office is included and the Palembang Office is excluded in the list.
         3 The assets in 2022 and 2023 that produced Scope 2 GHG emissions are ELB, EPE, MPE, MEB, DEB, MRPR, BJI, PPP and MPI Head Office.

 Indirect GHG Emissions (Scope 3)
 Our Scope 3 GHG emissions refer to the indirect GHG emissions that occur along our corporate value chain. They include all GHG
 emission sources that are not within our Scope 1 and Scope 2 GHG emissions.

 We are currently working on enhancing our internal systems and processes to identify, manage and disclose our Scope 3 GHG
 emissions. This includes establishing an inventory, delivering capability-building sessions, and engaging with our business partners.
 We aim to assure and disclose our significant Scope 3 GHG emissions and set reduction targets by 2025.



 Energy Performance
 At MedcoEnergi, we continuously implement programmes and initiatives aimed at securing energy efficiency to minimise our
 footprint. Furthermore, we regularly conduct energy audits to evaluate our consumption and identify opportunities to improve our
 performance.

 To calculate our energy consumption and intensity, we use the American Petroleum Institute (API) Compendium 2009, the GHG
 Protocol for Corporate Accounting and Reporting Standards from WBCSD and WRI 2004, the ISO 14064-1:2006, and Natural Gas
 (Second Edition: 2019) by James G. Speight.


 Oil & Gas
 In 2023, our total energy consumption for our oil & gas assets was 38,738,652 GJ, showing a 4.6% increase from 37,026,220 GJ in
 2022. There was also a 2.46-fold increase in energy consumption from renewable sources compared to 2022. The primary reasons
 for the increased consumption from renewable sources were because (1) domestic assets started using Biodiesel (B35) and (2)
 Onshore & Offshore assets installed solar PV.

         16 The significant increase in renewable energy consumption is mainly due to increasing biofuel and solar panel usage as well as the use of Biodiesel (B35) starting in 2023.
         17 The significant increase in non-renewable energy consumption is mainly due to increasing amounts of electricity production and operational hours in 2023 compared to 2022, which
            resulted in increases in natural gas consumption.
         18 The actual productions in ELB, MEB, DEB, and MRPR were the total amounts of electricity produced by the engines and sold to the third-party (PLN), while in MPE, EPE, BJI, and PPP, the
            actual production contains electricity sold to third-parties and used for internal consumption.
         19 Total energy consumption in Power is calculated as the sum of fuel consumption from both renewable and non-renewable energy sources plus electricity consumption, minus the
            electricity sold.
         20 The significant increases in energy consumption are mainly due to additions in operational assets. Hence, the amounts of electricity production also increased in 2022, followed by
            increases in energy consumption.
         21 The significant increases in energy consumption are mainly due to the increasing amounts of electricity production and operational hours in 2023 compared to 2022, which resulted in

 Strategic Initiatives
 We have undertaken the following efforts in our oil & gas assets to decrease GHG emissions.

                                                     Implemented 41 initiatives throughout 2023,
                                   with estimated peak annual1 GHG emission reductions: 147,963 tCO e

 We consider our GHG emissions reduction so far to be commendable, which have resulted from our operational efficiencies and
 improvements in most assets. Achieving such reductions involved enhancing operational efficiencies through technological upgrades,
 process optimisations and shifts to cleaner energy sources for operations. These changes also led to operational improvements that
 continue to benefit our company. We strive to continuously reduce our GHG emissions through various initiatives, which are guided
 by our targets to achieve net-zero emissions for Scope 1 and Scope 2 by 2050.

         Gas Engine Generator (GEG) Optimisations at Jene and Soka
         The South Sumatra Block identified eight GEG units running below optimum loads at the Soka and Jene stations. The subsequent
         optimisation initiatives led to increased load factors for the GEGs and reductions in total GEG use: from eight to six. These initiatives
         also saved USD 1,200 per day in fuel costs, with a total GHG reduction of around 3,000 tCO2e/year.


         Renewable Energy Certificates (REC)
         The Bangkanai and South Sumatra Block assets have implemented a strategic approach, shifting from sourcing their own power
         to purchasing electricity from the State Electricity Company (PLN) since 2022. These purchases were made partly through the
         Renewable Energy Certificates (RECs) from the hydroelectric energy provided by Medco Power Indonesia.

         In 2023, the redemption of RECs represents electricity generated from renewable sources amounting to 115.09 MWh in Bangkanai,
         and 86.36 MWh in the South Sumatra Block. Meanwhile, 69.10 MWh of electricity was generated from renewable sources in 2022 for
         both the Bangkanai and the South Sumatra Block.


         Corridor                 1

         Our Corridor asset actively evaluates and carries out various projects to lower our emissions. In 2023, we focused on two emission
         reduction initiatives that we determined to have maximum impact: optimising our processes and reducing flaring.

 Corridor Amine Process and Operating Mode Optimisation
 Corridor is processing gas from high CO2 fields like Sumpal, Dayung, Gelam, and Letang Tengah Rawa, and is facing challenges
 in managing utility consumption. In 2023, it implemented initiatives to improve operational efficiency, including adjustments to
 amine circulation and GTG operating mode, and shutting down the Thermal Oxidiser (TOX) operation. These efforts have significantly
 reduced fuel gas usage, potentially reducing GHG emissions by 97,000 tCO2e/year.


 Suban Amine Flash Gas Utilisation as LP Fuel
 Since 2020, amine flash gas has been used as a low-pressure (LP) fuel source in the Suban field, with efforts to optimise the process
 increasing its conversion into LP fuel. These measures have decreased fuel gas consumption by 0.6 million standard cubic feet per
 day (mmscfd) and prevented amine flash gas from being burned in TOX, reducing greenhouse gas emissions by 12,000 tCO2e/year.

         Single GTG Operation at North Belut
         The South Natuna Sea Block B opted to streamline its operations at the North Belut field following a thorough reliability assessment.
         This involved transitioning from two gas turbine generators (GTGs) to a singular GTG configuration. This strategic decision has resulted
         in noteworthy fuel conservation, estimated at approximately 0.35 mmscfd, thereby corresponding to an annual emission reduction
         of 6,930 tCO2e/year. Additionally, this transition has facilitated savings in maintenance expenditures.


         Refrigeration Unit Optimisation at Hang Tuah
         The Western Hub, comprising the Hang Tuah and Belida processing facilities, sends treated gas to buyers, with Hang Tuah serving
         as the sales gas hub. These facilities, powered by GTG, use the hydrocarbon dew point unit treatment through refrigeration to meet
         gas sales contract requirements. Declining production led to efforts to optimise gas treatment that focused on refrigeration unit
         performance across the Western Hub.

         Our analyses revealed that gas sales specifications could be met through treatment in Belida and adjusting gas blending ratios.
         Therefore, it allowed Hang Tuah's refrigeration unit to be placed on standby. This optimisation led to reductions in both GTG loads
         and emissions, by 1,980 tCO2e/year.


         Energy Audits at our Offshore Assets
         At MedcoEnergi, we conduct regular energy audits at least once every three years, as required by both Green PROPER and our
         Climate Change Strategy. We conducted energy audits for both South Natuna Sea Block B and East Java in 2022 that involved
         certified internal and external energy auditors.

         These audits recommended that energy consumption be more efficiently managed and operational efficiencies be enhanced.
         Among others, the audits recommended a solar PV light pole project in our Grati facility, East Java. These recommendations were
         implemented in 2023; as a result, this low carbon electrification in Grati could potentially reduce emissions by 34 tCO2e/year.



         International
         Our asset in Oman has transitioned from diesel generators to overhead line electricity to power the pumps in our Salwa Field
         operations. This electricity is sourced directly from our client, Petroleum Development Oman (PDO). By converting to electricity, we
         reduced GHG emissions by up to 431 tCO2e each year. We plan to expand this electrification programme to additional fields.

 Transitioning To
 Low Carbon Energy
 The strategies to transition to low carbon energy have allowed us to harmonise our activities with the energy transition as we shift
 from fossil fuels to renewable energy. Natural gas has become a transitional fuel to reduce emissions and address the increasing
 energy demands in the area. In response, we are expanding our natural gas production and renewable energy portfolio.

 In 2023, our power sales rose to 4,155 GWh, marking a 4.1% increase from the previous year. These escalating sales, paired with our
 expanded renewable energy proportions in our energy mix, reached 23% in 20231. We are thus on track to achieve our renewable
 energy mix target of 26% by 2025 and 30% by 2030.



 Our Energy Transition With Gas
 We strive to consistently increase our supplies of electricity with gas power. The following highlights our progress in gas infrastructure
 in 2023:

                                          275 MW                                                                   2x35 MW (Existing) + 39 MW (Add-on)

 Mini Hydropower
 Through PT Medco Hidro Indonesia, we operate two mini hydropower plants in West Java: Cibalapulang and Pembangkitan Pusaka
 Parahiangan, with a combined capacity of 18 MW.


 Wind Energy Project
 Medco Power is assessing a wind power plant in West Sumbawa. A feasibility study is underway, funded by the United States Trade
 and Development Agency (USTDA) Grant.


 Electric Vehicle (EV)
 We have started utilising EV in our operations in Jakarta, Pekanbaru and Batam, which includes EVs and charging infrastructure.


 Pursuing Decarbonisation Through CCS/CCUS
 At MedcoEnergi, we contributed to forming key government regulations and the Indonesian National Standards (SNI/Standar Nasional
 Indonesia) on carbon capture and storage (CCS) and carbon capture, utilisation and storage (CCUS). This was achieved by providing
 feedback through the Indonesia Petroleum Association (IPA) and directly participating in Indonesian government taskforces.

 We are also conducting studies on CCS at South Natuna Sea Block B, Gelam field in Corridor1 and Arung Nowera gas field development
 in South Sumatra. These efforts align with our Climate Change Strategy to remove carbon.


 Renewable Energy Certificates
 As part of our renewable energy adoption, Medco Power is commercialising our carbon attributes, Renewable Energy Certificates
 (RECs) and carbon credits. We have also registered with the recently launched Indonesia Carbon Exchange (IDX Carbon).




 Emerging Physical Climate
 Risk Management
 Climate Adaptation
 We conducted a CCRA that assessed the quantitative financial impacts of climate-related physical risks in 2023. This study’s approaches
 and findings can be read in the section “Assessing Our Climate-Related Risks and Opportunities”. Following that assessment, we plan
 to develop systems to regularly monitor climate hazards and their impacts.

 We are committed to adhering to national and international best practices for monitoring mechanisms. This will enable us to explore
 opportunities to maintain asset integrity and the safety of our employees amidst climate uncertainties.

         Climate Design
         We thoroughly assessed our new projects and operations, with climate change and biodiversity included as key indicators. Further
         details on our sustainability assessments are available in Chapter 6. In addition, we assessed activities such as maintenance and
         transportation that could pose environmental risks and contribute to climate change. For example, we assessed the biodiversity
         impacts that maintenance on Corridor’s pipeline right-of-way (ROW) might have near the Dangku Wildlife Reserve.

         We are incorporating climate risk assessments into future engineering designs. For instance, we have modified our platform designs
         to incorporate solar panels on our new offshore platforms.




                                                        Enhancing Transparency
         At MedcoEnergi, we guarantee transparency with our stakeholders regarding our ESG performance
         indicators, with a particular focus on climate change initiatives. We maintain the highest standards of
         integrity when presenting our performance data by adopting a third party limited assurance process
         for selected GRI indicators in our Sustainability Report (SR). Since 2017, we have progressively
         increased the number of assured indicators each year. In 2023, we covered 96 GRI indicators, a
         significant increase from the 2017’s 31 indicators. This demonstrates our ongoing commitment to
         enhance the quality and scope of our sustainability reporting as well as respond to stakeholders’
         feedback effectively.
         As part of the limited assurance process, our assurers visit selected oil & gas and power sites to gather
         evidence and documentation on selected GRI indicator samples. Each year, the assurers visit one oil
         & gas site and one power site. In 2023, the visit included the South Natuna Sea Block B oil & gas asset
         and the power assets of MEB and DEB. Sites that have been visited since 2018 include Rimau, South
         Sumatra Block, Corridor, South Natuna Sea Block B, MEB-DEB, ELB, and MRPR.
         These site assessments focused on emissions, energy use, occupational health and safety (OHS),
         local communities, and indirect economic impacts.
         The conclusion of this assurance process can be found on page 3 of this SR, and on the attached
         Limited Assurance Statement from KAP PSS - EY. The emissions and energy performance figures
         assured by KAP PSS - EY can be found on the GRI Performance Data 2023. For information on OHS,
         refer to Chapter 10, while insights into local communities and indirect economic impacts are available
         in Chapter 8.

 We aim to empower local communities around our operational areas to enhance their resilience and self-sufficiency. This commitment
 is reflected in our Community Development Policy, which is aligned with both the United Nations Sustainable Development Goals
 (UN SDGs) and national goals in the operating countries1. Our community development initiatives are designed to nurture local
 potential and improve welfare, fostering self-reliant communities. We carefully evaluate and prioritise community needs, integrating
 local wisdom into our programmes.


 Medco Oil & Gas’ Community Development Policy is available on our website here. This policy emphasises the following three key
 focus areas:

 In addition to the ESHIA, we assess the environmental and social                                   We aim to create opportunities for communities by sourcing

         Plans (RPJMN); our national SDG goals are directed by The Ministry of National Development Planning (Bappenas), Thailand has 4.0 Strategy to transform the Thai economy into a
         value-based economy, and Oman has the 10th Five Year Development Plan for its 2040 vision.

   resources, and cultures, based on accurate and relevant information, and without coercion or manipulation.

         Meaningful Engagements with Our Stakeholders
         In the framework of the Social Management System (SMS), we conduct stakeholder and social mapping activities to identify local
         stakeholders or communities of interest. These procedures are essential to ensure that we effectively address community needs and
         carry out our programmes in a culturally sensitive manner.



                                     Stakeholder Mapping                                                          Social Mapping

           This process involves registering stakeholders related to                        This process involves identifying the social structures,
           environmental and social issues and considering their                            relationships and dynamics of a community, including
           significance based on impact, stakeholder influence and                          analysing the social context, demographics, stakeholder
           interest.                                                                        relationships, culture and security.

           Based on this mapping, a Stakeholder Engagement Plan
           (SEP) is formulated to provide a platform for effective
           engagement based on issues and risks. The SEP is utilised
           in evaluating the implementation of our community
           development programmes.




         Our proactive and collaborative approach seeks to cultivate connections, trust, and confidence with local communities and other
         stakeholders. We believe that proactive SEP-based engagements can successfully mitigate potential risks and conflicts with
         community groups. Below, we outline the key roles involved in overseeing our community relations:

 Human Rights and Security
 Our Security Policy outlines our dedication to adhering to laws and regulations in our operating countries while upholding human
 rights. This policy is aligned with the UN’s Guiding Principles on Business and Human Rights and the Voluntary Principles on Security
 and Human Rights (VPSHR). It lays down our strategies to identify and report security threats as well as our response procedures.
 It serves as an initial framework for MedcoEnergi Oil & Gas to address human rights concerns identified in our Human Rights
 Assessments (HRA); see page 43-45.


 We also implement the Medco Security Management System (MSMS) across all oil & gas assets, leading to consistent enhancements
 in our security measures. This includes the organisation of various training sessions and capacity-building initiatives, such as the
 VPSHR, Gada Pratama, Gada Madya, and Gada Utama programmes. In 2023, 99.93% of Medco Oil & Gas and 100% of Medco
 Power security personnel participated in human rights training. The MSMS also enable us to map critical asset risks and follow them
 up through monthly monitoring and evaluating the security management plans.




 Supporting Community Livelihoods
 Our community development initiatives are designed to foster self-sufficient local communities. We maintain multi-year programmes
 tailored to meet the unique challenges and needs of the communities in our operational areas. Each of our assets routinely makes
 donations during the religious holy days to support underprivileged families and sponsors activities to commemorate Indonesia’s
 Independence Day.

 Promotion of Sustainability Initiatives by Our People
 Implementing Sustainable Farming and Producing Organic Fertilisers
 Contributions to communities can also be accomplished by
 individuals in our workforce. One example came from Januari
 Samosir, a QA/QC painting/coating inspector serving one of our
 contractors in South Sumatra. Off duty, Samosir became both
 a farmer and organic fertiliser producer, engaging in organic
 farming on his own plot of land near his residence. He engages
 with the community to help them divert their organic waste
 from landfills and transform it into fertilisers.


 Samosir’s experience as a QA-QC professional made him realise
 that his reliance on synthetic fertilisers hindered his agricultural
 success. By transitioning to organic methods, he began producing
 his own fertilisers from local organic waste. He also does not use
 chemical fertilisers or herbicides, nor does he resort to burning
 to clear his farmland.


 As a result, his commitment to sustainable farming practices has
 preserved soil health and biodiversity. It also increased his farm’s
 yields and promoted environmental harmony. Samosir aims to
 expand his organic farming to contribute to local food security
 and environmental sustainability.

 female representation has reached 19.6% at the management

 by the Jakarta Special Provincial Government (Daerah Khusus

         Facilitating Full Office Integration
         Since our acquisition of the Corridor asset in March 2022, we facilitated integration with the team and achieved significant process
         milestones in 2023. In June 2023, we completed the relocation of Corridor employees’ assets to the Energy Building in Jakarta.


         We implemented our activity-based working office facilities, ensured operational compliance with Health, Safety and Environment
         (HSE) standards and improved facilities. This integration not only enabled a smooth transition for our employees but also contributed
         to a 24% reduction in office space, achieving greater cost efficiency and workplace effectiveness.


         Our efforts resulted in an improved employee experience, as indicated by survey results, safety received a favourable score of 92%
         and the physical working environment received 81%. The latter encompasses positive evaluations of facilities, workspace, safety, and
         other aspects.



         Strengthening Our Medco Leadership
         Behaviours (MLB)
         Our Medco Leadership Behaviours (MLB) were introduced in 2022. They define the exemplary leadership behaviours derived from
         our corporate values. We encourage all our employees to embody these behaviours.

 The MedcoEnergi Awards: Celebrating Innovation and Excellence
 MedcoEnergi organises a Corporate-level contest annually, known as the MedcoEnergi Awards, to highlight the achievements
 of significant innovations and improvements. The competition aims to recognise and appreciate successful innovations and
 improvements that are in line with the Company’s values. It also seeks to foster a culture of innovation and collaboration, enhance
 employee capabilities, and promote both sustainability and climate change initiatives. The competition includes all employees,
 secondees, direct contract employees, and third-party contractors across MedcoEnergi’s corporate, Medco Oil & Gas domestic and
 international, and Medco Power assets.


 The contest includes four categories: Fit-For-Purpose Technology, Production/Revenue Enhancement, HSE and Sustainability
 Excellence, and Business Process Improvement. It has consistently attracted widespread interest among employees, with 508
 abstracts submitted in 2023. The selection process was rigorous, involving abstract submissions, a coaching clinic on paper writing for
 the shortlisted 100 abstracts, and the submission of the papers themselves.


 These papers were then narrowed down to the top ten for each category, and subsequently to the top five. On 14 December 2023,
 five outstanding finalists from each of the four categories presented their innovative projects to a panel of distinguished judges at the
 MedcoEnergi Award presentation day, held at The Energy Building in Jakarta. Three winners were chosen from each category, along
 with one ‘Best of the Best’. In total, 13 winners were honoured with Certificates of Achievement by the Board of Directors and received
 prizes. These winners were announced during the “New Year Speech” event in January 2024. The winners were celebrated for their
 innovative and excellent contributions to the Company and the broader industry.




                           2023 MedcoEnergi Award’s ‘Best of the Best’ winner received the award from our President Commissioner

         We focus on advancing OE at Medco Oil & Gas in 2023 by executing strategic improvement plans that have resulted from the latest
         OE assessments. This promotes the exchange of leading practices across assets and builds competency through assurance.




                                                      Executing Strategic Improvement Plan
                                                      We focused on executing the Strategic Improvement Plan in 2023, which was a follow-up from
                                                      the OE assessment results. A comprehensive OE self-assessment was conducted for the newly

                                                      plans for continuous improvements.


                                                      The assessment identified leading practices in competency assurance, leadership visibility, risk

                                                      Integrating these practices into our operational framework is crucial to reaching Level-31 maturity
                                                      in OE.



                                                      Cross-Asset Knowledge Exchange in Implementing Leading Practices
                                                      We consistently foster collaboration across assets and functions. As a result, we have driven
                                                      numerous improvement projects, including management of change for facilities, management of
                                                      change for personnel, and safety critical element risk assessments.


                                                      We also conducted the Operational Excellence Forum to engage key personnel in discussions
                                                      facilitated by experts. These aimed to extract insights, enhance visibility, and embed a culture of

                                              Competency Assurance
                                              We actively enhance employee skills through targeted mentoring and assessments every three
                                              years for Operation Personnel to ensure alignment with role-specific requirements. For example,
                                              in 2023, we conducted an upskilling mentoring programme for onshore production operators.


                                              We are committed to meeting standards set by both the Ministry of Energy and Mineral Resources
                                              (MEMR) and the Ministry of Labour for license to operate of all operations personnel. For this
                                              reason, in 2023 we conducted thorough training efforts that ensured continuity post-COVID19 for
                                              personnel trained during and after the pandemic.

                                              outlined in PTK-0051. It assessed our HSE Management Systems (HSEMS) and practices against
                                              government regulations.


                                              We achieved scores of 99.7% for Rimau, 99.6% for Corridor, and 100% for South Natuna Sea
                                              Block B assets. We earned praise from SKK Migas for being the first Production Sharing Contractor
                                              (PSC) to develop and successfully execute the audit with outstanding outcomes. SKK Migas also

         We implemented Process Safety Management across all assets,                We implemented a robust Defect Elimination (DE) process. It
         including Asset & Operating Integrity, to educate personnel                involved comprehensive identifications, captures, and analyses
         on safety practices. Standardisation efforts included Process              of defects using diverse data sources such as event codes,

         We also aligned our Operability Assurance (OA) with Operational Excellence and integrated its standards into all major capital projects.
         This approach ensured that operations and project stakeholders collaborated to address operability, reliability, and maintainability. It
         also facilitated smooth operational integration and met OE requirements in initial operations. As of 2023, OA has been applied not
         only to IPP projects such as Ijen Geothermal IPP, East Bali IPP, and ELB Add-On, but also to ensure readiness in O&M Services, such
         as in Timor-1 and Sulut-1 Power Plants.

 Our Health, Safety, and Environmental
 Management System (HSEMS)
 Our HSEMS is an integral part of the OE framework. This management system enables us to systematically identify, assess, control,
 and monitor operational HSE risks to the business, employees, contractors and the environment. The HSEMS requires each asset and
 business unit to plan, coordinate and monitor HSE implementation throughout our operations. Our contractors and suppliers are also
 required to adhere to this management system.


 The HSEMS Manual outlines managerial responsibilities for health and safety issues and ensures that HSEMS is implemented and
 communicated effectively across our business. Its roles and responsibilities are outlined below.

 Our HSEMS at operating assets1 aligns with ISO 45001:2018 for Occupational Health and Safety (OHS) Management Systems and
 ISO 14001:2015 for Environmental Management Systems (EMS). We maintain certifications for both standards – a list of certified oil
 & gas and power assets is on page 87 of this report.


 Our Management System for oil & gas assets also complies with the Indonesian Government’s Regulation No. 50/2012 on the
 Implementation of the OHS Management System and the Ministry of Energy and Mineral Resources (MEMR)’s Safety Management
 System for the Oil & Gas Industry (Sistem Manajemen Keselamatan Migas/SMKM).




 1   While we are ensuring HSEMS alignments with relevant ISO standards in our operated assets, we are also influencing our non-operated assets to implement HSEMS and/or align with
     relevant ISO standards.

 Health and Safety
 Performance
 We actively monitored our occupational health and safety (OHS) performance, utilising key performance indicators (KPIs) to pinpoint
 areas to improve and ensure effective programme implementation. We continuously focused on improving our Total Recordable
 Injuries Rate (TRIR) for both Medco Oil & Gas and Medco Power. Our ultimate targets are to have zero incidents and consistently
 maintain rates below the TRIR of the International Association of Oil & Gas Producers (IOGP).


 Our Consolidated TRIR decreased from 0.21 in 2022 to 0.15 in 2023 although the work activities increased around 10%1 compared to
 2022, reflecting a positive trend. Notably, we achieved zero fatalities for the third consecutive year, underscoring our commitment to
 safety. The following graph illustrates our TRIR performance with the latest benchmarking data2:

 HSE Engagements with Contractors
 Maintaining our safety culture requires effective engagements with our contractors. To achieve this, we have developed programmes
 to instil accountability and promote transparency among our contractors.



 Contractor HSE Forum & Workshops
 Continuing our Contractor HSE Forum from the past years, in November 2023 we organised a contractor forum for Medco Oil & Gas
 in collaboration with Corporate HSE and other assets. The focus was on “Leveraging Contractor Leadership & Commitment through
 HSE Plan Execution and Learning Organisation.” This event provided a platform for constructive dialogues and knowledge-sharing,
 which fostered a deeper understanding of how HSE plans are executed.

 Contractor Management Initiatives
 We enhanced insights taken from historical data and developed a contractors’ HSE performance dashboard to visualise and monitor
 contractors’ performance as well as trace historical records in Oman.

         Contractor Safety Ambassadors
         We appointed “Contractor Safety Ambassadors” to uphold
         safety protocols and minimise incidents. They are responsible
         for implementing the programmes, which included mentoring,
         coaching, monitoring sessions as well as weekly reports to upper
         management.
