In alignment with the Sustainable Development Goals (SDGs) outlined by the United Nations, PTT places paramount importance on addressing the needs and expectations of all stakeholders in an equitable manner. To this end, PTT has delineated a "Sustainability Strategic Direction" within its "PTT's Sustainability Management Master Plan for Social and Environmental Responsibility for 2021 - 2025", encompassing three key dimensions: environment, society, and governance. This strategic blueprint delineates short-term, medium-term, long-term goals, and strategies aimed at driving success while upholding social and environmental responsibility. PTT is committed to achieving sustainability performance that ranks in the 1st Quartile of prominent international indicators, such as the Dow Jones Sustainability Indices (DJSI), thereby reinforcing its alignment with the 20-year national strategy and steadfast support for the SDGs.

Supporting the Sustainable Development Goals (SGDs) 

PTT meticulously assesses the priorities of sustainable development goals (SDGs) pertinent to its business operations, considering them as pivotal input factors in charting the strategic direction and enterprise plan of the organization. Aligned with key sustainable development objectives, PTT employs a comprehensive 3-step review process, outlined as follows:

  1. Conduct an in-depth analysis of significant internal and external factors affecting the organization, encompassing the corporate vision and strategic direction. This entails sustainability materiality issues, policies, strategic directions, goals, and operational plans, alongside discerning trends and shifts in global sustainability that could impact business operations across the value chain. Moreover, it involves understanding the diverse needs and expectations of stakeholders. 
  2. Define priorities and response levels to the Sustainable Development Goals (SDGs) by consulting operational manuals at the international level, such as the UN Global Compact's SDG Ambition Integration Guide, the UN Global Compact's SDG Compass, IPIECA's Mapping the Oil and Gas Industry to the SDGs: An Atlas, and the SDG Sector Guide. Additionally, utilize roadmaps provided by WBCSD and manuals like "Accelerating Action: An SDG Roadmap for the Oil and Gas Sector" developed by IPIECA in collaboration with WBCSD. Ensure alignment with the master plan outlined in the 20-year National Strategy (2018-2037) and The Thirteenth National Economic and Social Development Plan (2023-2027), relevant to PTT's operations. Prioritize SDGs into two groups: the first comprising 10 goals integrated into core business processes ("Integrated into Core Business"), and the second involving 7 goals that necessitate collaboration with sustainability networks or stakeholder participation ("Collaborate with Other Stakeholders"). Goal 17, particularly emphasized, serves to support and facilitate the achievement of other SDGs.
  3. Explain the prioritization process and operational directives to related departments, serving as a blueprint for formulating enterprise plans. Develop strategies and initiatives supporting the management of critical sustainability concerns, alongside establishing frameworks for fostering relationships with stakeholders in responsible domains.

Assessment of MaterialityGRI 3-1, GRI 3-2

The process of sustainability materiality assessment at PTT is aligned with the Global Reporting Initiatives (GRI) Universal Standards 2021 and the Corporate Sustainability Reporting Directive (CSRD) requirements. This process identifies sustainability risks and opportunities across environmental, social, and governance dimensions, considering human rights throughout the organization's business operations.. It encompasses both actual and potential impacts, both positive and negative. It evaluates the impacts on stakeholders, society, and the environment (Impact Materiality) and the impacts of external factors on the organization's financial performance (Financial Materiality) throughout the value chain, following the concept of Double Materiality. Due diligence materiality assessment is conducted annually and integrates into the annual enterprise risk assessment process to review changes in the context of internal/external factors and evolving circumstances, with 4 main steps as follows:


Step 1: Understand the organization’s context
Consider internal factors (such as vision, mission, strategic objectives, organizational risks, and operations/ activities) and external factors (such as standards, requirements, best practices, global trends, and relevant risks), as well as consider material topics from PTT Group and industry peers. Additionally, PTT also analyzes internal and external stakeholders' needs and expectations throughout the value chain from organizational activities through surveys/ public hearing/ interviews for material topic grouping and prioritization.

Step 2: Identify actual and potential impacts
Identify actual and potential impacts, both positive and negative, in Environmental, Social, Governance dimensions with the consideration of human rights impacts throughout the organization’s operations. It starts from actual and potential negative impacts that may happen in the future. This includes those the organization causes, contributes to, or is directly linked to for business benefits from the organization’s value chain. Next, identify the positive impacts that have occurred and have potential in the future to deliver value for sustainable development.

Step 3: Assess the significance of the impacts
Assessing the impacts on society and the environment (Impact Materiality) and the impacts on the organization's financial performance (Financial Materiality) by analyzing both quantitative and qualitative aspects of both positive and negative impacts.

Negative impacts
When evaluating the potential impacts, it is important to consider both the negative and positive impacts. The severity of negative impacts should be assessed by considering their scale, scope, and whether they are irremediable. Additionally, the likelihood of negative impacts occurring in the future should also be taken into account.

Positive impacts

The significance of positive impacts should be evaluated by considering their scale and scope. The potential positive impacts that are likely to occur in the future should be determined by considering both their scale, scope, and the likelihood of occurrence.

Step 4: Prioritizing Impacts for Reporting Purposes

Prioritize the impacts and select materiality topics for management and disclosure purposes in the 56-1 One Report and PTT website. The company conducts a thorough analysis of the Impact Materiality on society and the environment and the Financial Materiality on the organization's financial performance. This assessment undergoes a collaborative review with relevant functions and experts. It is all under the oversight and approval of PTT's committees at the management and board levels, including the Governance, Risk and Compliance Management Committee (GRCMC) and the Corporate Governance and Sustainability Committee (CGSC), respectively. In addition, materiality assessment process verified by a third-party assurance provider. PTT engages external experts and agencies to review and assurance the process and outcomes of the materiality assessment. This is to ensure completeness, accuracy, reliability, and transparency. The company considers observations from these experts and external agencies to continuously improve operational processes and information disclosure practices.

2023 Materiality Assessment
GRI 3-2, GRI 3-3

In the 2023 materiality assessment, the material issues emerged concerning both social and environmental impacts, as well as the influence on the financial performance of the organizations. The top 3 priority topics and the issues that have changed from 2022 are as follows: 

  • Climate Action remains a top priority following the previous year, as it remains an internationally significant global agenda. The issue was emphasized during the 27th Conference of the Parties to the United Nations Framework Convention on Climate Change (COP27) to limit the increase in temperature to 1.5 degrees Celsius compared to pre-industrial levels. As a national energy company under the Ministry of Energy, PTT has a mission to reduce Thailand's greenhouse gas emissions in the energy sector. Therefore, PTT integrates climate change risks and opportunities assessment into its annual strategic planning and risk management processes. This involves considering energy transition risks, financial impacts related to climate change, and identifying new business opportunities in the transition to a low-carbon economy. PTT has set long-term targets and strategies to prepare for this risk by transitioning its business toward "Future Energy and Beyond". These targets include New Growth, Business Growth, and Clean Growth through Portfolio Transformation. These strategies have been clearly outlined in the organization's strategic plan, which aligns with the vision of "Powering Life with Future Energy and Beyond” and aimed at expanding operations towards a low-carbon society and achieving Net Zero Emission.
  • Innovation and Technology have increased their ranking significantly due to new business development and expansion in which innovation and technology play important roles. Companies are focusing on developing new sustainable products and services that cater to the needs of their current and future stakeholders. This includes supporting the energy transition following the vision "Power Life with Future Energy and Beyond", which involves expanding into new businesses that go beyond energy, adjusting investment portfolios to include low-carbon businesses, such as renewable energy, electric vehicles, and life sciences. PTT emphasizes the importance of promoting creativity and innovation both within and outside the organization. This includes developing new products and services, improving work processes, and creating new businesses that improve efficiency and effectiveness. These efforts aim to increase business competitiveness and achieve sustainability goals. To achieve these goals, PTT has set ‘New Growth’ corporate target for increasing revenue from growth in the future energy value chain and expanding into new businesses. The company has also developed the "PTT Innovation Management Master Plan" to guide its operations and strategies. In addition, the business expansion has a potential impact on the "Water Management" in the future involving physical and transition risks that may arise from climate change.

  • Occupational Health and Safety PTT employees and contractors are at risk of exposure to hazards arising from their work in the oil and natural gas industry that may lead to irreparable health injuries/ illnesses or loss of life. All of these can financially result in the cost of property damage, loss of income from business disruption, remedies, fines, etc. PTT is therefore committed to improving management, safety, and business continuity of the company to be efficient, flexible, and ready to accept all types of risks without affecting business operations and stakeholders. PTT has set strategic direction “Promote safe working environment and respecting the human rights principles” in the “Sustainability Management Master Plan for Social and Environmental Responsibility for 2021 - 2025” in the Social dimension to leverage occupational health and safety operations, such as compliance with basic and task-specific safety rules, health surveillance, analysis and management of process safety event risks, Bow Tie and Barrier Validation, PTT health reporting system, and transportation safety management.
