PTT’s Stakeholder Engagement Process

PTT systematically integrates and identifies the issues, needs, expectations, and concerns of its stakeholders by first conducting a value chain analysis across its business units and supporting units, aligned with the organization’s structure. This enables the comprehensive identification of both internal and external stakeholders, ensuring that the unique perspectives of each group are thoroughly captured. Each unit then identifies issues, needs, expectations and concerns of each stakeholder group in a comprehensive manner. The stakeholder groups and organizational issues will be used as a guideline for considering stakeholders and related issues of each unit. To further enrich this process, additional sources of information are taken into account, including: 

• Analysis of global trends and directions
• Corporate strategic direction and annual business plan
• Material issues of sustainability identified through impact assessments related to the economy, environment, people, and human rights 
• Results from stakeholder surveys, conducted at least annually 
• Recommendations and input from relevant committees, such as the Enterprise Risk Management Committee (ERMC) 

Based on the analysis of stakeholder needs, expectations, concerns, and the value chain assessments conducted across each business unit, PTT develops targeted stakeholder engagement plans. These plans clearly outline the objectives, scope, stakeholder groups, key issues, and measurable key stakeholder indicators (KSIs). Progress on stakeholder engagement is reported to senior management at the business unit level on a quarterly basis, enabling regular review and the incorporation of feedback for continuous improvement. At the corporate level, PTT also provide an overview of key issues to be monitored at the corporate level to track progress in stakeholder engagement by reporting quarterly to the Corporate Planning and Risk Committee (CPRC) and the Enterprise Risk Management Committee (ERMC); which serves as specialized subcommittees under the PTT Board of Directors. In 2025, a total of nine key stakeholder issues were identified at the corporate level. These issues reflect stakeholder needs and expectations that are actively integrated into the company’s ongoing operational and strategic improvements. 

1. Brand & Trust focuses on strengthening the overall image, awareness, and trust in the PTT brand across the corporate identity, products, and services. This also includes activities that contribute to social well-being, environmental stewardship, and national development.
2. Climate Change involves providing information for relevant agencies to support relevant government policies and regulatory frameworks related to climate change management. The objective is to help transition Thailand toward a low-carbon society through proactive efforts to reduce greenhouse gas emissions.
3. Compliance & Transparency refers to strict adherence to applicable laws and regulations, alongside the transparent and ethical conduct of business in accordance with principles of good governance. This includes timely and accurate disclosure of positive information, as well as robust measures to safeguard stakeholder data privacy and information security.
4. Financial Performance encompasses the Company’s ability to deliver strong and consistent financial results that inspire stakeholder trust. This includes key financial performance indicators, financial ratios, responsible accounting and taxation practices, and a strategic focus on sustainable, long-term business growth. 
5. Hydrocarbon & Power covers operations to support government policies and regulations, as well as fostering collaboration with relevant stakeholders to expand business opportunities and enhance the country’s energy security in key business groups, including:
   
   • Upstream & Power, which includes exploration and production, natural gas, and electricity businesses, as well as renewable energy.
   • Downstream, which includes petrochemical and refining, retail, and international trading businesses
6.

7. Organization & Employee focuses on enhancing organizational capabilities by integrating innovation and digital technologies as a core driver for transforming workflows and improving operational efficiency. It also emphasizes developing employee potential by equipping them with the knowledge, skills, and competencies required to meet the expectations of both the organization and its workforce. Key initiatives include upskilling & reskilling, on-the-job learning, and fostering a culture of continuous learning within the organization.
8. Safety, Health & Environment refers to the management and operations of a work environment that prioritizes the safety, occupational health, and environmental well-being of employees.
9. Supplier & Customer Experience is about cultivating positive and mutually beneficial experiences between the organization and its suppliers or customers. This involves creating an impression of doing business together, delivering high-quality products and services at fair prices, ensuring timely and reliable delivery as agreed.

The analysis results of the value chain for each business unit  can be summarized as follows: 

Strategic Stakeholder Engagement Approach ^{GRI 2-29}

PTT has established criteria for selecting key issues to monitor at the corporate level, based on an analysis and scoring of priority issues from business units (Bottom-up) and corporate perspective (Top-down). This process takes into account the alignment of corporate issues with both internal and external factors, such as global trends, Sustainable Development Goals (SDGs), government policies, state enterprise development plans, corporate strategic direction, and the needs and expectations of stakeholders. As a result, four key issues have been identified for corporate monitoring: 1) Climate Change, 2) Hydrocarbon & Power, 3) Non-Hydrocarbon & New Business, and 4) Brand & Trust. For each issue, engagement plans have been developed to strengthen relationships. For instance, with regard to Climate Change, PTT emphasizes its commitment to conducting business in a manner that promotes sustainable and balanced growth. The plan focuses on balancing Environmental, Social, and Governance (ESG) factors in line with the organizational context, alongside efforts to reduce greenhouse gas emissions, aiming for carbon neutrality by 2040 and Net Zero Emissions by 2050. This will be achieved by promoting hydrogen-related businesses and Carbon Capture and Storage (CCS) projects. The PTT Group will integrate efforts, set clear roles and shared goals, and leverage the strengths of each company for maximum benefit. PTT will govern the overall strategy through the C³ framework, which includes:

(1) Climate Resilience Business: Focuses on investing in businesses that adjust their portfolios to promote low-carbon operations and sustainability
(2) Carbon-Conscious Asset: Enhances existing assets to reduce carbon emissions by implementing energy-saving measures, utilizing clean energy sources such as hydrogen, and applying advanced technologies like Smart Plant solutions to improve operational efficiency.
(3) Coalition, Co-Creation, and Collective Efforts for All: Collaborates with the government and business partners to drive investments in carbon capture and storage (CCS) technology and promote activities like forest planting to absorb carbon.

PTT is accelerating investments in infrastructure to support carbon capture from the production processes across the PTT Group, particularly in offshore areas of the Eastern region, with a target to capture and store 6 million tons of CO₂ annually. The project is expected to begin by 2030. Additionally, PTT is investing in international hydrogen businesses to further support clean energy adoption. The Company aims to incorporate a 5% hydrogen blend into gas pipelines for electricity generation by 2030. PTT is also exploring the feasibility of investing in Small Modular Reactors (SMR) as part of the new Power Development Plan (PDP) to help reduce carbon emissions in the future.

Furthermore, PTT is enhancing carbon dioxide absorption through natural methods by planting and maintaining forests. The Company plans to plant 1 million rai of inland and mangrove forests by 2030, and to maintain 1 million rai of forest under Permanent Reforestation Project, initiated in 1994. PTT Reforestation and Ecosystem Institute, through the Wang Chan Forest Learning Center, has been recognized by the Thailand Greenhouse Gas Management Organization (Public Organization), Ministry of Natural Resources and Environment for its waste management efforts, which have reduced greenhouse gas emissions by 4.848 tons of CO₂ equivalent. Additionally, the Sirinart Rajini Learning Center has expanded its knowledge on waste management, leading to a reduction of 6.848 tons of CO₂ equivalent. These activities demonstrate PTT’s commitment to integrating efforts across all sectors and sharing knowledge to drive tangible carbon reduction outcomes.
