Sustainable Development

Materiality Assessment Process

In 2020, PTTEP reviewed material topics on sustainability through interviews and questionnaires on all stakeholders as well as the analysis of likelihood of opportunities and risks of factors that may affect the Company. The results were classified into 2 groups: material issues of the Company's operations and stakeholders' concerns and expectations. Being added up were global sustainability trends and direction in line with UN SDGs and DJSI as well as the energy industry's material issues. The assessment process was completed in line with GRI Standards as follows.

1. Identification

   Considered the company's business strategy, enterprise risks, and challenges, as well as social, business, and environmental activities, in conjunction with the stakeholders' suggestions, expectations, and interests.

2. Prioritization

   Once the key material issues were identified, PTTEP assessed these issues in two dimensions: the significance to PTTEP and the significance to stakeholders. The prioritized issues are presented in the form "Materiality Matrix" by

   - X (horizontal axis) is "significance of each materiality to PTTEP"
   - Y (vertical axis) is "significance of each materiality to stakeholders"

   PTTEP consider the issues in the upper-right quadrant to be the most significant,

3. Validation

   The Board of Director and The Management Committee reviewed and approved the material issues for disclosure in the sustainability report and web content. An external audit was carried out to verify the transparency, accuracy, and completeness of the disclosed information.

4. Review and Report Development

   Improved the participation procedure, as well as gathered feedback and recommendations from stakeholders to further improve the report to better reflect the stakeholders' issues.

Materiality: 2. Increasing Petroleum Reserves

Report Topic: Business Sustainability

Target	2020 Progress	SDGs
5% CAGR Production Growth by 2030. Maintain Proven Reserves to Production Ratio (R/P Ratio or 1P/Production) at no less than 5 years. Unit cost in the top quartile among peers. (≤25 USD/BOE) • 20% of the Net Income from non E&P business by 2030.	Production growth rate at 2% as a consequence of the COVID-19 outbreak and low oil price. The proportion of natural gas production accounted for 70% of all production in 2020. Proved R/P Ratio or 1/P Production is at 7 years Unit cost was at 30.50 USD per barrel of oil equivalent, maintaining PTTEP's competitive advantage in the Petroleum E&P industry in Asia. Won the bid for Block Offshore 3 field, in partnership with Eni, for an offshore exploration block in the United Arab Emirates, a region known for low operating costs Signed the Exploration and Production Sharing Agreement (EPSA) with the Ministry of Energy and Minerals in the Sultanate of Oman for the 12th onshore exploration block. The block accounted for approximately 10,000 square kilometers and is located in central Oman, where the Oman government mainly conducts exploration, development, and production of natural gas. The operation is implemented in partnership with TOTAL E&P, which is equipped with several years of experience in Oman. Made two successful deep-water oil discoveries in Mexico's offshore Block 29 with good quality reservoirs. Discussions with co-operators on resources evaluation and development are underway, before seeking an approval from Mexico's regulatory body. Expanded AI Robotic Venture Ltd., according to expansion strategy in new business and establish two joint venture companies, namely ATI technology CO LTD, a platform provider by using smart farming technology to assess agricultural in-debt data to strengthen the Thai agriculture sector. The company is also operating in collaboration with Thaikhom PCL LTD to develop drone-related products and services for agriculture. Seaquest Explorer CO.,LTD, in partnership with Mermaid Maritime CO LTD, provides a subsea (IRM) service that focuses on robotic technology and Artificial Intelligence (AI), such as an examination and maintenance robot and sub-sea petroleum pipeline. Signed a Project Finance loan agreement to cover the developmental cost of the Mozambique Area 1 project for the two lines of liquefied natural gas production after the final investment decision was announced in 2019 to support future liquefied natural gas production. Signed Asset Sale and Purchase Agreement to acquire an additional 24.5% stake in the Algeria Hassi Burracez project from China National Offshore Oil Corporation (CNOOC), one of the co-investors, with a value equal to the CNOOC's investment spent from the project development period to the official date of approval. The project is currently pending approval from the Algerian government. This acquisition led PTTEP to have a total investment of 49% in this project (Algeria's national oil company, SONATRACH is the main co-investor with 51% stake). The project is expected to begin early stages of production at 10,000-13,000 barrels per day in late 2021 and will increase production to 50,000-60,000 barrels per day in 2025.
