Management Approch
Reporting Process
The determination of sustainability reporting content is aligned with Airports of Thailand’s (AOT) enterprise-wide risk management approach, the Global Reporting Initiative (GRI) Standards 2021, and the Double Materiality principle. AOT reviews and defines material sustainability topics on an annual basis.
In 2024 (Fiscal Year 2024), AOT reviewed its material sustainability issues by taking into consideration various factors such as changes in applicable laws, regulations, national and international assessment standards, as well as emerging global trends in both sustainability and the aviation business. To address the expectations of all stakeholder groups, AOT conducted an analysis of both positive and negative impacts arising from its operations, as well as external risks and opportunities that may affect the organization’s performance.
The materiality assessment process comprises four key steps:
Step 1: Review of Previous Material Sustainability Issues
AOT gathered and analyzed data across all business activities—including airport services and capacity expansion at its six airports—along with the interests of its seven key stakeholder groups (customers; shareholders, investors, and analysts; business alliances; local communities and society; regulatory authorities; media; and AOT personnel) throughout the value chain. In addition, AOT reviewed economic, environmental, and social issues relevant to its operations to gain a comprehensive understanding of the organization’s context. This served as a foundation for reviewing and updating material sustainability issues.
Benchmarking was also conducted against peer companies with similar business operations, as well as national and international standards, emerging trends, and assessment frameworks. This comparative analysis ensured that AOT’s material topics remain up to date and aligned with evolving market expectations and global sustainability standards.
Step 2: Impact Identification
AOT analyzed and identified the economic, environmental, and social impacts resulting from its business operations. This process covered both positive and negative impacts—whether direct or indirect—arising from various activities carried out by AOT. Impact identification was conducted through stakeholder engagement activities, including workshops and opinion surveys, to ensure a clear understanding of the extent to which these impacts affect stakeholders and how they align with the Sustainable Development Goals (SDGs).
Step 3: Impact Analysis
AOT developed a weighted heat map based on calculated scores for each material sustainability topic. This analysis incorporated benchmarking of peer companies and the review of national and international standards, trends, and assessment frameworks. References included the Dow Jones Sustainability Indices (DJSI), the United Nations Global Compact (UNGC), the Sustainability Accounting Standards Board (SASB), and the SET ESG Ratings. AOT also began preparing for the transition of its ESG assessment framework from SET ESG Ratings to FTSE Russell ESG Scores, as initiated by the Stock Exchange of Thailand.
Step 4: Consolidation of Material Sustainability Issues
Based on AOT’s 2024 review and assessment of material sustainability issues, the issues were prioritized into three levels: Highest Priority, High Priority, and Priority. This categorization enables AOT to effectively plan and respond to sustainability challenges and opportunities. The finalized material issues were presented to the President for approval and endorsement prior to public disclosure.

Material Issues for Enterprise Value Creation
In 2024, AOT identified and reviewed a total of 13 material sustainability issues, taking into consideration the expectations and concerns of both internal and external stakeholders. These issues comprehensively cover the economic, social, and environmental dimensions as follows:

Remarks: * The issues on corporate governance, risk management and business ethics are the fundamental issues of business operations that have already been disclosed in the Annual Registration Statement/Annual Report (Form 56-1 One Report). Therefore, the information is not included in this report.
1. Human Capital development
AOT’s business operations rely on a knowledgeable and capable workforce. To ensure employees can perform to their full potential, the Company places strong emphasis on comprehensive human capital management. This includes fostering favorable employment conditions, conducting performance-based evaluations, offering appropriate incentives, and promoting well-being without discrimination.
This approach forms the foundation of AOT’s human resource strategy, which encompasses talent development, attraction and retention of high-potential employees, fair labor practices, competitive compensation and benefits, and respect for diversity and inclusion. AOT is committed to being an employer that provides meaningful work and supports the holistic well-being of its workforce.
In doing so, AOT actively promotes human rights by ensuring fair employment, equal treatment, appreciation of individual differences, and upholding the freedom of association and collective bargaining.

2. Corporate governance, risk management and business ethics
The AOT Board of Directors is committed to upholding the Company’s corporate governance principles, in accordance with AOT’s Corporate Governance Code, the best practices for directors of listed companies, as well as the rules, regulations, and guidelines set forth by the Stock Exchange of Thailand (SET) and the Securities and Exchange Commission (SEC).
Moreover, the Board continually strives to enhance AOT’s corporate governance framework to align with international best practices. Good corporate governance is crucial to building trust among all stakeholders. Shareholders and investors are assured of transparent and fair management practices, which contribute to long-term value creation and investment returns. Simultaneously, customers and service users benefit from high-quality, safe, and equitable services, along with efficient channels for feedback and complaint resolution. Employees and personnel also gain from these governance practices, ensuring fairness and fostering a supportive work environment.

Materiality Issues for External Stakeholders
1. Energy and climate changes
The management and expansion of airport infrastructure require substantial energy consumption, which contributes to greenhouse gas emissions—both directly from AOT’s operations and indirectly through its supply chain. These emissions are key contributors to climate change, which increasingly manifests in more frequent and severe natural disasters, exceeding historical averages. Therefore, effective energy and climate management by AOT not only mitigates these impacts on communities and society, but also addresses the expectations of key stakeholders—including shareholders, investors, securities analysts, and regulatory bodies—who are increasingly focused on sustainable investments and compliance with international sustainability requirements.
Classification | Material Issues for External Stakeholders |
Source of Impact | AOT’s operations—both at the airport level and by airport users—require significant energy consumption and emit greenhouse gases. |
Impact | Greenhouse gas emissions contribute to climate change, which in turn affects communities through long-term impacts such as air pollution and the increasing severity of natural disasters. |

2. Environmental and natural resource management
Airport operations, along with the development and expansion of infrastructure, require systematic management to address the environmental impacts arising from business activities. This is essential for mitigating both positive and negative effects on various stakeholder groups, particularly regulatory authorities, shareholders, investors, and securities analysts—who hold significant interest in and expectations for AOT’s management practices.
AOT places strong emphasis on environmental impact management, focusing on key issues including noise management, air quality, water and wastewater, waste management, and biodiversity. These environmental aspects have the potential to create far-reaching impacts in various forms. Accordingly, AOT recognizes the importance of managing potential risks through the implementation of established environmental management measures and plans to ensure that operations align with long-term environmental sustainability.
Classification | Material Issues for External Stakeholders |
Source of Impact | AOT’s operations—both airport infrastructure and user activities—require significant consumption of natural resources, and generate various forms of waste and air/noise pollution. |
Impact | Surrounding communities are exposed to air and noise pollution from airport operations, as well as water shortages during drought periods. Additionally, communities near AOT's waste disposal sites may experience adverse environmental effects. |
Impact Assessment |
