Human Rights Impacts from PTT’s Operations

Since 2015, PTT has developed and implemented a human rights management system in conjunction with its sustainability management efforts. The company conducts comprehensive Human Rights Due Diligence (HRDD), which cover the operations of PTT and subsidiaries under the PTT Group’s Way of Conduct. The most recent HRDD assessment, conducted in 2023, identified several key human rights risks, including employee and contractor safety and occupational health, labor rights, working conditions of suppliers, community living standards, and the rights of indigenous peoples.

Management Approach

PTT’s Human Rights Policy

PTT acknowledges the critical role of human rights in the organization’s long-term sustainability and has made respecting human rights a fundamental part of its corporate culture. The company adheres to national laws and international human rights standards, including the Universal Declaration of Human Rights (UDHR), the United Nations Guiding Principles on Business and Human Rights (UNGP), and the International Labor Organization (ILO) Declaration on Fundamental Principles and Rights at Work. PTT clearly communicates its commitment to respecting human rights through a Human Rights Statement of PTT Public Company Limited, which is signed by the CEO and President. This statement outlines PTT’s dedication to preventing, managing, and reducing the risk of human rights violations against all stakeholders in its operations, in accordance with legal requirements, international standards, and corporate principles. Additionally, it underscores the commitment to adhering to the company's policy on governance and ensuring compliance with the laws, rules, and regulations of PTT Public Company Limited.

Governance Structure, Roles, and Responsibilities of the Board and Management in Human Rights Management

PTT’s approach to human rights is integrated into its broader sustainability management framework. The Corporate Governance and Sustainability Committee (CGSC), a subcommittee of the PTT Board of Directors, is responsible for overseeing the policies and management of sustainability initiatives across the PTT Group. This includes the management of human rights throughout PTT's supply chain. In addition, the PTT Board provides guidance, advisory support, and ensures the monitoring of progress to drive the organization toward achieving sustainability. The Board is composed of distinguished members with deep expertise, knowledge, and experience in managing the human rights impacts across various sectors. For example:

The performance of PTT’s Board of Directors is evaluated through a comprehensive performance incentive system, which includes key issues related to the environment, social impact, governance, and human rights. This system is aligned with the State Enterprise Assessment Model (SE-AM). PTT has established a fair and reasonable compensation policy for its directors. (Further details can be found in the 56-1 One Report, Section 2, Corporate Governance, under the topic Compensation of PTT Directors, as well as under the Corporate Governance section on the Company’s website).

At the management level, the Governance, Risk, and Compliance Management Committee (GRCMC) oversees risk management and ensures adherence to laws, regulations, and organizational standards. Additionally, the Assistant Managing Director for Strategy and Corporate Sustainability, reporting to the Executive Vice President for Corporate Sustainability, is responsible for developing processes and overseeing the management of sustainability and human rights across PTT and the entire PTT Group. These processes are effectively communicated and implemented across relevant corporate departments, ensuring smooth integration and operational efficiency throughout the organization. Key departments involved include human resources, safety and security, occupational health and environmental protection, corporate social responsibility, procurement, and legal compliance, among others.

The Corporate Governance and Sustainability Committee holds quarterly meetings to track progress, provide input on policies, long-term and annual goals, assess key sustainability issues (Material Topics), human rights risks, operational plans, and risk management strategies. Over time, the committee has consistently offered recommendations for enhancing the human rights management system and processes. In addition, progress reports are submitted to the PTT Board of Directors. Furthermore, PTT has designated management-level employees with expertise in human rights to oversee day-to-day operations, ensuring the prevention of any potential human rights violations in PTT’s activities, including dealings with suppliers.

PTT’s Human Rights Management Process

The PTT Group Human Rights Management System was developed in 2015 and formalized through the creation of the PTT Group Human Rights Management Guideline. This guideline serves as the official framework for managing human rights issues related to the operations of PTT and its subsidiaries. It covers all activities across the company's value chain that may have potential human rights impacts, ensuring that human rights considerations are integrated throughout the business.

PTT actively promotes the adoption and adherence to the PTT Group Human Rights Management Guideline across its subsidiaries, following the PTT Group Way of Conduct. Each company within the Group is required to disclose their risk assessments and corresponding risk mitigation plans as part of the sustainability governance framework on a quarterly basis. Additionally, they must report their progress to PTT, which compiles the information for submission to the Board of Directors.

PTT Exploration and Production Public Company Limited

IRPC Public Company Limited

PTT Global Chemical Public Company Limited

Thai Oil Public Company Limited

Global Power Synergy Public Company Limited

PTT Oil and Retail Business Public Company Limited

Currently, PTT has systematically integrated its human rights management framework into the broader sustainability management processes of the organization. This includes identifying human rights issues and risks through comprehensive human rights due diligence, which is considered one of the key impact areas in assessing the material sustainability topics of the organization.

The human rights impact of each material sustainability issue is actively addressed through the PTT Group Sustainability Management Master Plan for 2021–2025. This plan sets annual targets and long-term goals, including a commitment to Zero Human Rights Violations by 2030. In addition, strategies and action plans are developed, with clear performance indicators aligned with the state enterprise evaluation system, corporate KPIs and functional KPIs. The progress on these goals and plans is reported quarterly to the Board of Directors within the sustainability governance framework.

Human Rights Due Diligence (HRDD)^{GRI 407-1, GRI 408-1, GRI 409-1}

PTT Public Company Limited recognizes the critical importance of upholding and promoting human rights principles and regulations to ensure the sustainability of its operations in alignment with both domestic laws in Thailand and international standards. The company is committed to implementing preventive measures against human rights violations for its employees, business partners (including contractors, suppliers, goods and service), customers, and local communities.

Identifying and assessing risks related to human rights violations are integrated into various risk assessment processes in critical stages of business activities. These include conducting due diligence during mergers and acquisitions, performing Environmental Impact Assessments (EIA) for large-scale construction projects, as required by law, which allows stakeholders impacted by human rights issues to participate in evaluating the effectiveness of mitigation measures. Additionally, safety and occupational health risks are assessed according to ISO standards across all operational areas. Furthermore, human rights-related risks are included in the internal control processes of all departments within the organization. All identified risks are managed by setting appropriate mitigation measures and management plans, which are reported to management periodically for review.

Regarding Human Rights Due Diligence (HRDD) in accordance with international standards, including the United Nations Guiding Principles on Business and Human Rights (UNGPs), PTT has developed an operational plan to regularly review and improve the HRDD process every two years or whenever there are changes in business activities or significant events that may substantially alter risks or impact human rights. This includes business expansion into new regions or countries, or entering areas with higher human rights risks.

The primary objective of the HRDD process is to identify and assess both current and potential human rights issues throughout the entire value chain. This process includes the operations of PTT and its business partners, such as contractors, suppliers, and service providers. The key goal of identifying and assessing human rights issues is to proactively reduce risks through the implementation of mitigation measures and to effectively manage potential human rights violations. The operational steps involved are as follows:

1. Defining the Group’s business scope.

2. Defining the context of human rights.

3. Identifying/assessing human rights issues at the operational level and related rights at the individual level.

4. Risk assessment.

5. Identifying controls and mitigating risks.

6. Evaluating residual risks.

7. Monitoring and reviewing.

Human Rights Risk Assessment Process

PTT has implemented a Human Rights Risk Assessment (HRRA) as an integral part of its Human Rights Due Diligence (HRDD) process. This assessment focuses on identifying human rights issues related to the company’s operations and activities throughout its entire value chain, including those within the PTT Group and across all its business segments (100%).

The HRRA process involves reviewing and monitoring the current measures in place to manage human rights risks throughout PTT’s business operations and related activities across the entire value chain. The main objective is to identify, mitigate, prevent, and address any potential human rights risks.

The steps in the Human Rights Risk Assessment process are as follows:

Identification of Human Rights Issues
PTT identifies all human rights issues associated with its operations and business activities with partners. This process takes into account the potential impact on the business and stakeholders who may be affected, including vulnerable groups such as women, children, indigenous peoples, local communities, migrant workers, third-party contracted labor, persons with disabilities, pregnant women, and the LGBTQIA+ community. To ensure a comprehensive assessment, PTT reviews industry standards and trends, comparing its practices with similar industries and consulting both internal and external sources of information on global human rights issues.

In identifying these issues, PTT incorporates insights from previous consultations with stakeholders, along with feedback from both internal and external experts. Additionally, PTT will analyze and identify further risk factors in alignment with its investments in various countries, business operations, and relationships with new business partners.

Labor Rights	Community	Security	Environment	Customer and Consumer	Corporate governance
Work Environment Freedom of association and collective bargaining Forced labor and labor conscription Child labor Safe and healthy working conditions Non-discrimination Non-sexual and sexual harassment Human trafficking Equal remuneration Personal data	Standards of living and quality of life Comunity health and safety Community participation Cultural heritage Minority groups, including indigenous peoples Displacement and resettlement	Safety management Knowledge and understanding of security and safety related to human rights	Water resources Impact of pollution Waste and hazardous material management Impact on biodiversity Challenges in accessig energy	Health and safety of consumers Data privacy	Anti-corruption and anti-bribery Legal compliance Human rights regulations

Assessment of Inherent Risks
Evaluate the inherent risks (those without any control or mitigating measures) associated with the identified human rights issues.
Assessment of Residual Risks
Evaluate the residual risks (risks remaining after PTT’s control measures have been applied) associated with the identified human rights issues.
Prioritization of Risks
Prioritize the identified human rights issues based on the severity of residual risks, focusing on those with the highest level of remaining risk.

Assessment of Actual or Potential Impacts
Scope of Human Rights Risk Assessment: PTT’s Operations and Activities Throughout the Value Chain

The scope of PTT’s human rights due diligence and risk assessment includes the operations of PTT and its subsidiaries, in line with PTT’s governance framework, covering the entire value chain.

Rights Holders and Vulnerable Groups

PTT thoroughly considers all rights holders who may be impacted during its Human Rights Due Diligence process, ensuring a comprehensive approach for every group. These groups include employees, suppliers, external workers, contractors, business partners, local communities, customers/consumers, and vulnerable groups (migrant workers, women, indigenous peoples, LGBTQIA+ individuals, the general public, people with disabilities, vulnerable individuals, and children). PTT emphasizes its commitment to respecting human rights across the entire supply chain by raising awareness among these groups through appropriate communication channels, including:

Employees: This includes comprehensive training from day one, such as SSHE courses, introductory human rights training sessions, and internal communications through channels like emails and videos to raise awareness.
Business Partners: This involves activities such as annual supplier seminars (both at the corporate and business unit levels)
Other groups; such as networks, associations, institutes, and government agencies.

The assessment of human rights risks is conducted considering two factors: impact and likelihood.

Human Rights Risk Assessment Criteria: Impact

The impact on human rights is evaluated based on a range of factors, including geographical, social, and economic conditions, as well as the scale, scope, and irremediability nature , which are the limitations of efforts to address and mitigate negative impacts, aiming to restore the situation to its original state.

Impact
Severity	Scale	Scope of Affected Right Holders	Irremediability Nature
Extremely High (4)	Severely affects the health and safety (both physical and mental) of the right holders, including: Resulting in permanent disability Posing a life-threatening risk	Affects all right holders (e.g., the entire community, all employees, all partners, all customers) and/or vulnerable groups of two or more individuals	Restoration to the original condition is impossible and/or will take an extended period to recover (more than 5 years).
High (3)	Significantly affects the health and safety (both physical and mental) of the right holders, leading to work stoppage	Affects the majority of right holders (over 50% of the group) and/or a vulnerable group of one individual	Recovery will take a significant amount of time to restore to the original condition (more than 3-5 years).
Medium (2)	Mildly to moderately affects the health and safety (both physical and mental) of the right holders, necessitating medical treatment	Affects a portion of right holders (less than 50% of the group)	Recovery will take a period of time to restore to the original condition (1-3 years).
Low (1)	Has minimal to no impact on the health and safety (both physical and mental) of the right holders, requiring only basic first aid or medical attention.	Does not impact the rights holders	No time or only a very short time is required to restore to the original condition (less than 1 year).

Human Rights Risk Assessment Criteria: Likelihood

Likelihood
Possibility	Frequency and/or Possibility	Likelihood
Extremely High (4)	It has occurred regularly and/or is likely to occur regularly (occurs daily/weekly).	A very high likelihood of occurrence (More than 20%)
High (3)	It has occurred frequently and/ or is likely to occur often (occurs monthly/ quarterly).	A high likelihood of occurrence (More than 10% to 20%)
Medium (2)	It has occurred but not frequently and/or is unlikely to occur (occurs once a year within 1-2 years).	A low likelihood of occurrence (More than 5% to 10%)
Low (1)	It has almost never occurred and/or is highly unlikely to occur (occurs no more than once every 3-5 years).	Almost no chance of occurrence (Below than or equivalent to 5%)

Human Rights Risk Matrix

The human rights risk assessment will be conducted using the matrix provided below to prioritize human rights issues based on their significance.
The assessment of human rights risks involves two dimensions:
- Impact (the severity of the impact, the number of affected rights holders, and the ability to remediate the negative consequences)
- Likelihood
The scope of the assessment covers all rights holders who may be impacted (including vulnerable groups), due to potential human rights violations.
Salient Issues refer to those human rights issues that are identified as “Extreme.”

Integration of Operations

Since 2015, PTT has conducted a thorough human rights risk assessment across all its core business units, including natural gas and international trading. In 2019, the scope of this assessment was expanded to include businesses in which PTT has investments through its subsidiaries, aligning with the PTT Group's management principles (PTT Group Way of Conduct). This now encompasses PTT and 16 subsidiaries, totaling 17 companies, covering 50 locations in 21 countries. The assessment spans a wide range of industries including petroleum exploration and production, petrochemicals and refining, oil and retail, coal, power generation and distribution, and new business and infrastructure sectors. This covers 100% of the operational areas managed directly by PTT, as well as 100% of the areas managed by PTT within its Group.

Corrective/ Preventive Measures

Complaint Management and Remediation^GRI2-25

Complaint Management^{GRI2-16, GRI411-1}

PTT has developed a comprehensive complaint management system that caters to both internal and external stakeholders. This system includes expanded categories for complaints, ensuring that stakeholders from all groups can access and submit their concerns conveniently at any time. It supports both Thai and English to accommodate a diverse range of issues, including grievances, concerns, and suggestions from those who may be affected. For international subsidiaries within the PTT Group, stakeholders can reach out via the company’s website and regional social media channels, which offer support in local languages.

PTT adheres to a policy that guarantees timely, clear, equitable, and transparent management of complaints, maintaining confidentiality and protecting complainants. This policy ensures there is no retaliation, dismissal, punishment, or any form of harassment towards the complainant or witnesses. PTT does not require complainants to maintain confidentiality or forgo their right to seek legal recourse through court or alternative legal processes. Every complainant will receive confirmation that their concern has been entered into the complaint system via electronic mail, and they can monitor the progress of their case through the complaint and labor relations system. Furthermore, PTT provides dedicated channels for reporting violations of business ethics by external parties, including the 1365 Contact Center, the CEO’s Office, the Governance and Ethics Promotion Department, the Corporate Communications Department, and the Investor Relations Department.

Additionally, PTT has established a "Whistleblowing Channel" available on its website at www.pttplc.com and via "PTT Voice" (pttvoice@pttplc.com). These channels provide stakeholders with a platform to report any violations or corrupt activities within the organization. The information received is promptly forwarded to the appropriate department for review and further action, in accordance with established procedures. Furthermore, PTT has reviewed and updated its corporate policy on complaints and whistleblowing regarding corruption, abuse of authority, misconduct, and non-compliance with laws and regulations, as outlined in the 2022 PTT Public Company Limited Policy. This updated (Whistleblowing) policy sets clear criteria and guidelines for addressing reports of corruption, abuse of office, misconduct, and legal or regulatory violations . It ensures a transparent, consistent, and fair approach to investigations and oversight across the organization, with protective measures in place to safeguard and ensure fairness for whistleblowers and individuals who assist in providing relevant information.

These staff collect complaints, needs, expectations, and potential impacts from PTT's operations, which are then used for corrective actions. They also help design effective communication channels and complaint systems tailored to each community.

PTT encourages its business partners to establish grievance mechanisms for receiving complaints from both internal and external stakeholders. Additionally, PTT supports its partners in setting expectations for their suppliers to promote grievance mechanisms, ensuring that all stakeholders across the supply chain have access to appropriate remedies.

Remediation

PTT places great importance on the protection and remediation of individuals who may be affected by human rights impacts arising from its operations. The company ensures accessible grievance mechanisms in all situations, especially in cases of emergencies or crises in specific locations. Additionally, PTT does not obstruct or restrict affected individuals or human rights defenders from accessing justice and remedial processes, whether through public authorities or the company itself. Regarding of access to remedy, PTT commits to providing immediate remedies in both monetary forms, including compensation payments, financial assistance, and non-financial support such as setting up emergency grievance points, offering initial assistance, providing guidance, or enlisting expert advice. PTT has developed structured communication channels to systematically gather feedback and grievances from stakeholders, as demonstrated in the following examples:

Business Partners: PTT encourages its business partners to provide feedback and suggestions for improving the grievance system during the annual partner seminars. Feedback collected from these sessions is used to enhance the grievance system, ensuring alignment with user input, such as improving personal data management practices and displaying grievance channels on the website.
Employees: Relevant departments invite employee representatives to provide feedback and test the internal grievance system.

PTT ensures that all affected stakeholders, including both employees and external parties (individuals and communities), have access to grievance channels through project-specific grievance centers or the PTT Call Center. The company systematically analyzes complaints, takes corrective actions, and implements preventive measures in accordance with established procedures. In cases where the initial remedial process does not resolve the issue, PTT employs both judicial and non-judicial grievance mechanisms. This involves collaboration with independent bodies, such as a tripartite working group that includes representatives from stakeholders, local government bodies, community leaders, and relevant government agencies. By using this collaborative approach, PTT ensures effective and appropriate management of grievances, leading to the satisfaction of all parties involved.

Communication and Training^GRI410-1

PTT actively communicates its human rights statement and the management of sustainability issues and impacts, including mitigation measures, through various channels to ensure stakeholders are informed and understand the progress and resolution of grievances. Communication is directed at different stakeholder groups through appropriate means such as community engagement in operational areas, public listening sessions, and outreach to citizens via the website and press releases. Additionally, stakeholders at the organizational level, including investors and business partners, receive updates through the 56-1 One Report, annual business partner seminars, and other forums. For further details, please refer to the section Driving Business for Sustainability and the subheading Building Relationships with Stakeholders in the 56-1 One Report.

Internally, PTT places a strong focus on regularly raising awareness about human rights within the business for all employees. This is achieved through various channels, including articles, internal newsletters, and emails. These communications cover key topics such as human rights statements, policies, principles, guidelines, the human rights management system, and case studies from various business sectors. Furthermore, PTT provides sustainability management courses and fundamental human rights training for employees at all levels involved. The training includes workshops and video content that cover human rights practices in business operations, along with examples of best practices for conducting business in a manner that respects human rights.

In 2024, PTT launched communication and training initiatives to enhance employee awareness of business and human rights. These initiatives covered various topics relevant to its trends and situations, including:

Human Rights Situation in Myanmar, presented by instructors from the Chulalongkorn University Asia Research Institute.
Business and Human Rights, conducted by experts from the Friedrich Naumann Foundation.
Online Course: Fundamental Human Rights Management (E-Learning), aimed at providing employees with a solid understanding of human rights within business operations. This course is designed to meet stakeholder expectations, build trust, and promote sustainable business growth. It is available to all employees across all levels. Additionally, PTT developed video materials to support the integration of human rights respect into the organizational culture, accessible to both employees and visitors.

Furthermore, PTT has implemented a training program for its security personnel. The company requires security providers to deliver essential training to their staff prior to performing duties, focusing on human rights principles, including the right to security as a fundamental human right, the prohibition of using violence, even against wrongdoers. Moreover, security personnel only have the right to detain individuals committing offenses on PTT premises, and those accused are presumed innocent until proven guilty. Each year, PTT and its group companies provide security personnel with training on handling various situations, such as community blockades or protests. PTT works closely with local communities to enhance safety and prevent violence at operational sites (particularly in situations where security personnel are required to use force in areas of operation affected by war or conflict). Training also covers procedures for addressing threats, intimidation, and violence against women.

In 2024, PTT did not receive any human rights complaints related to its security personnel.

Human Rights Collaboration Network

PTT is a signatory to the United Nations Global Compact (UNGC) and an active member of the Global Compact Network Thailand (GCNT), demonstrating its commitment to conducting business in line with the 10 universally recognized principles. Furthermore, PTT consistently provides valuable feedback to the government to support the development and implementation of Thailand’s National Action Plan on Business and Human Rights (NAP) and the National Human Rights Action Plan.

Suppliers and Partners Across the Supply Chain

PTT encourages its business partners throughout the supply chain to respect human rights and align with PTT’s human rights policies. This commitment begins with the selection of both new and existing suppliers, who are evaluated not only on standard criteria such as quality and financial stability but also based on environmental, social, and governance (ESG) performance. Suppliers who fail to meet the established standards are excluded from the PTT Approved Vendor List (PTT AVL).

core principles that encompass human rights, including business ethics, social responsibility, environmental stewardship, and safety. This code applies to suppliers entering contracts with PTT worth 2 million baht or more and/or involving work that may have an impact on safety or the environment. Compliance with these principles is closely monitored through regular audits and assessments, which have been in place since 2016, with particular attention given to high-risk and critical suppliers. In the event of violations of the Sustainable Supplier Code of Conduct, corrective action plans must be implemented. PTT also reserves the right to terminate contracts if such violations persist.

Promoting Diversity, Equality, and Inclusion

PTT's Human Rights Statement reflects the company's commitment to fostering an environment where differences are respected and everyone is treated equally. This principle is embedded in practices ensuring that all stakeholders can trust that there will be no discrimination in recruitment, human resources management, training, and employee development. (For further details regarding diversity, such as the proportion of female employees, average compensation for men and women, and religious diversity indicators, please refer to PTT's website under the section Human Resource Management.) PTT ensures that no form of discrimination occurs based on age, disability, gender, marital status, pregnancy, maternity leave, political views, race/ethnicity, religion, beliefs, sexual orientation, socio-economic status, labor union membership, work arrangements, family status, or any other factors unrelated to job performance at PTT.

PTT has established clear behavioral standards and disciplinary procedures, which are communicated to all employees. If an employee violates these standards, their supervisor will issue a warning. In more severe cases, the violation is considered a disciplinary offense, and the employee will face appropriate penalties based on the nature of the offense.

Discriminatory actions, exclusion, sexual harassment, gender-based harassment, or any action that limits rights or benefits—whether direct or indirect—without justification, based on gender, gender expression, nationality, race, religion, language, age, disability, or health status (Item 3.8 of the HR Regulations, Section 20, Standards of Conduct and Disciplinary Offenses), are treated as disciplinary violations. Any employee engaging in such actions will face consequences according to the company’s disciplinary procedures (Item 3 of the HR Regulations, Section 20, Standards of Conduct and Disciplinary Offenses). These offenses are classified as moderate violations and may result in the suspension of a salary increase for up to six months the following year (as outlined in Item 2 of the attached guidelines for disciplinary measures and penalty considerations).

Human Rights Management Process Review

The human rights management process encompasses a thorough assessment of human rights risks, the development of measures to manage and mitigate these risks and impacts, communication and awareness-building on human rights for executives and employees, the process of receiving and handling human rights complaints, and continuous monitoring and reporting of outcomes to the Governance Committee. This process is regularly evaluated for its effectiveness and efficiency by the Internal Audit department every three years. The audit results are reported to the Internal Audit Committee at the Board level. In this regard, the latest audit, conducted in 2024, found no issues requiring further improvement.

PTT Group's Investments in the Republic of the Union of Myanmar

PTT adheres to the fundamental principle of respecting human rights and expresses deep concern regarding the violence following the 2021 coup in Myanmar. The company strongly supports peaceful efforts to resolve the crisis and is committed to adhering to the rule of law and international practices across all its operational areas. PTT continuously monitors the situation in Myanmar, adjusting decision-making and management processes to ensure its investments align with sustainable development goals and promote equitable access to energy resources. PTT remains hopeful that the situation in Myanmar will soon stabilize and return to normal.

PTT Exploration and Production Public Company Limited (PTTEP), a subsidiary of PTT, has invested in natural gas development projects in Myanmar. In response to the 2021 political crisis, PTT has closely monitored the situation, assessing the potential impacts on the company and its stakeholders. It has implemented corrective and preventive measures to strengthen governance and management practices. The Executive Committee of the Petroleum and Natural Gas Business Group has considered various potential impacts, both business operations and social dimension, such as worker safety, local community concerns, energy security, which directly affect the quality of life of citizens and any human rights violation. The Committee reviewed these risks and reported them to the PTT Board for further direction and the establishment of appropriate mitigation/prevention strategies. Additionally, PTTEP has assessed human rights risks in Myanmar, a country with significant human rights concerns, particularly regarding the Yadana and Zawtika projects, in light of the coup. PTTEP has introduced measures to prevent and reduce the risk of human rights violations resulting from the company’s operations. The primary human rights concerns identified are: (1) ensuring the safety and security of employees and contractors in operational areas during the political unrest, and (2) addressing disputes regarding the continued natural gas supply for electricity generation in both Myanmar and Thailand. The electricity produced from these projects is an essential public utility that supports the development of people’s quality of life, drives economic growth, and contributes to national development. Additionally, equitable access to energy is recognized as a fundamental human right for all people. PTTEP continues to closely monitor the situation, with a focus on ensuring the safety of employees and maintaining energy security for Myanmar. The company has established a Workplace Coordination Committee (WCC) to oversee safety, security, occupational health, environmental management, and the well-being of all stakeholders, including employees and contractors. PTTEP ensures compliance with international human rights standards, while also respecting local cultures, traditions, values, and national laws in every operational area, including Myanmar.

PTT, as the major shareholder with a key role in overseeing its subsidiaries, has implemented corrective and preventive measures in related processes as follows:

PTT has appointed the Chief Executive Officer (CEO), the Managing Director, and the Chief Operating Officer (COO) of the upstream Petroleum and Natural Gas Business Group as members of PTTEP's Board of Directors. These individuals receive detailed, ongoing reports on the situation, allowing them to provide feedback, suggestions, and direct guidance as necessary.
PTT has strengthened its adherence to the investment guidelines and budget management regulations for both PTT and its subsidiaries, as well as its approach to overseeing investments in companies where PTT holds shares. This ensures a robust process for decision-making, monitoring, and managing investments across PTT and its subsidiaries. The process is supported by Strategic Investment Management (SIM), which includes an Investment Management Committee made up of executives with specialized expertise. This Committee thoroughly evaluates and screens investment proposals before presenting them to PTT's management team for approval, which then submits them to the PTT Board for final approval. Investments with high capital value or significant risk, especially those involving major sustainability considerations, are required to be reviewed by the Corporate Risk Management Committee. This provides additional insights to guide the PTT Board's investment decisions. Once an investment receives approval from the PTT Board, its progress is closely monitored and reported quarterly to the Investment Management Committee, the PTT management team, and the PTT Board.
PTT Group has established a dedicated committee to address the international sanctions imposed on Myanmar. This Committee is chaired by the Chief Operating Officer of the upstream petroleum and natural gas business group and includes senior executives from PTT and its subsidiaries with investments in Myanmar. The Committee’s primary responsibilities include closely monitoring the evolving situation and its direct and indirect impact on all stakeholders. It is also tasked with reviewing, defining, and executing urgent and comprehensive corrective and preventive measures.

In light of the situation, PTT and its subsidiaries have been identified as having operations that may not fully align with their human rights statement and other public policies. In response, PTT has reinforced its internal control processes. Relevant policy-owning departments are now responsible for closely tracking and analyzing any developments that may affect the company’s operations. They are also charged with identifying and evaluating risks within the organization and throughout the value chain that could result in non-compliance with established policies. Should potential risks emerge, systematic and timely corrective and preventive actions will be taken.
In response to the ongoing situation in Myanmar, PTTEP has strengthened its safety, security, occupational health, environmental management, and human rights practices in its operational areas within the Republic of the Union of Myanmar. These enhanced measures are aimed at containing, preventing, and minimizing risks to the health, safety, and property of employees and contractors in the region.
PTTEP has been proactive in communicating and clarifying critical information to stakeholders in a transparent and timely manner. The company regularly provides updates regarding its decisions and actions, ensuring stakeholders are well-informed. This includes official communications such as letters to the Stock Exchange of Thailand, press releases, and information shared on the company’s website.
Furthermore, PTTEP remains committed to its ongoing social development projects, focused on improving the quality of life in the communities where it operates. Given the current situation, PTTEP expresses deep concern for the welfare and safety of all people in Myanmar and remains hopeful for a swift resolution, so that Myanmar can return to peace and stability as soon as possible.

In April 2024, PTTEP became the majority shareholder of the "Yadana Project" in Myanmar, which supplies natural gas to Thailand. This occurred after Unocal Myanmar Offshore Company Limited (UMOC), a subsidiary of Chevron, withdrew its investment, increasing PTTEP's shareholding to 62.963%. In response, PTT has heightened its efforts to closely monitor the situation, in accordance with PTT’s Human Rights Statement and compliance policies.

To address potential risks, the following preventive risk management measures have been put in place:

A review of compliance policies to incorporate sanctions-related provisions.
The establishment of a comprehensive Compliance Framework that includes processes for third-party screening.
The implementation of PTT Public Company Limited’s 2022 regulations on the criteria and verification of entities involved in transactions with PTT.
The development of guidelines and processes for assessing third-party qualifications based on prohibited criteria (Blacklist).
The adoption of the Dow Jones Risk & Compliance ("Dow Jones") tool to ensure that departments conducting transactions with third parties perform thorough background checks before proceeding.
The creation of educational materials to enhance understanding of policies, operational frameworks, manuals, and the third-party screening process.

PTT Group: Mediation Efforts in Class Action Lawsuit Regarding the Montara Incident and Seaweed Farmers in Indonesia

PTT Group firmly upholds respect for human rights as a core practice and prioritizes environmental conservation in all its business operations. In this case, PTT Group has engaged in mediation efforts to resolve a dispute between PTTEP Australasia (Ashmore Cartier) Pty Ltd, a subsidiary of PTTEP, and a group of seaweed farmers in the Republic of Indonesia (Indonesia). The farmers are seeking compensation for damage to their seaweed farms caused by the Montara incident in Australian waters in 2009. The mediation process follows the Federal Court of Australia’s ruling and complies with the normal legal procedures of Australia for class action lawsuits. On February 23, 2023, the Federal Court of Australia approved an agreement in principle, establishing a framework for compensating the affected group members according to the court-approved process.
