Sustainable Development Goals

Positive and Negative Impacts 

Biodiversity is a cornerstone in ecological systems, essential for maintaining equilibrium and ensuring the sustenance of various life forms, including humans. Leveraging biodiversity data has become pivotal for economic advancement and bolstering a nation's competitive edge. However, the trends of urbanization and industrial expansion have cast shadows on biodiversity in multifaceted ways. These include alterations in land usage, environmental degradation, and climate fluctuations, which may inexorably lead to the gradual extinction of vulnerable species unable to adapt naturally. Such outcomes perpetuate adverse impacts on life and property.

Recognizing the profound implications of its business operations, activities, and entire value chain on the environment, biodiversity, and ecosystem services, PTT remains acutely cognizant of its responsibilities. The construction of facilities, installation of natural gas pipelines, and product transportation by road and sea are just a few examples of operations that could potentially disrupt biodiversity and ecosystem services, thereby impacting community and societal well-being. Consequently, PTT employs a comprehensive approach to proactive management, which includes implementing measures to mitigate impacts and undertaking a variety of community projects and initiatives. This concerted effort yields positive environmental outcomes, enhancing both local communities and societal well-being in a sustainable manner. To ensure alignment across its operations, PTT has developed guidelines for assessing biodiversity and ecosystem services loss, guided by principles of impact mitigation at every stage of project implementation as follows:

  • Avoidance: Implementing measures or guidelines aimed at avoiding the impacts of projects on biodiversity.
  • Reduce: Developing strategies to reduce the impact on biodiversity and environmental service systems, including minimizing duration, intensity, and defining the scope of unavoidable impacts.
  • Restore: Implementing measures for the restoration of degraded environmental systems or ecosystems that have been adversely affected and cannot be avoided.
  • Offset: Establishing measures to offset the impacts on environmental systems in cases where avoidance is not feasible.


PTT is dedicated to effectively managing and mitigating biodiversity impacts, aiming for alignment and coherence across the entire PTT Group. The shared goals include:

  • Developing Biodiversity Action Plans (BAP) in areas identified as having high biodiversity risk, ensuring comprehensive coverage.
  • Conducting No-Net-Loss Assessments for new projects in high-risk areas, striving for 100% completion by 2024 for oil & gas companies and by 2025 for Flagship companies. This supports the overarching objective of the Group to prevent any net loss of biodiversity.

Management Approach

PTT Biodiversity Policy 

PTT's Biodiversity Policy underscores the paramount importance of biodiversity across the entire business spectrum, as clearly articulated in the PTT Group QSHE Policy. Additionally, to reaffirm its dedication to conducting business with due regard for biodiversity impacts, PTT has issued the "PTT Biodiversity Statement." This statement pledges to abstain from exploration, exploitation, and business operations in areas designated as global heritage and conservation sites by the IUCN. Moreover, PTT is steadfast in its commitment to preventing any net deforestation and implementing reforestation or tree planting initiatives as compensation in areas affected by future business endeavors. This commitment extends to key stakeholders, including Tier-1 suppliers and Non-tier 1 suppliers, with implementation goals set for PTT's new projects by 2024.

Management of Biodiversity Impact

PTT has established comprehensive management guidelines aimed at showcasing its dedication to environmental protection, conservation, and mitigation of environmental impacts, with a strong focus on biodiversity and ecosystem preservation. These guidelines ensure that considerations for biodiversity impacts are integrated into decision-making processes and business operations across the entire value chain. Key aspects of these guidelines include:

  • Incorporating biodiversity risk management into the PTT Group's QSHE Policy.
  • Implementing biodiversity management practices in environmentally vulnerable areas or neighboring regions in alignment with international laws and standards, following the prescribed procedures outlined in the Group's biodiversity management and ecosystem service provision protocols.
  • Demonstrating an unwavering commitment to achieving No-Net-Loss of biodiversity within manageable boundaries.
  • Enhancing biodiversity value not only within operational areas or adjacent regions but also through investment activities aimed at social welfare or partnerships with external entities, such as the Mangrove Forest Ecosystem Learning Center and Wang Chan Forest Learning Center.

Guidelines for Biodiversity and Ecosystem Services Management

Within the framework of its commitment to biodiversity management, PTT has established guidelines for managing biodiversity and ecosystem services. These guidelines are developed with reference to international standards such as the International Finance Corporation Performance Standard 6 (IFC6) - Biodiversity Conservation and Sustainable Management of Living Natural Resources (2012), and the Business and Biodiversity Offset Program (BBOP). They encompass the following operational procedures:
  • Risk assessment for biodiversity and ecosystem services.
  • Assessment of biodiversity loss for new projects.
  • Formulation of action plans for biodiversity in operational areas deemed high-risk and potentially impactful on biodiversity.
  • Monitoring, reviewing, and evaluating performance.
  • Conducting annual reviews and assessments against the established biodiversity management and ecosystem service guidelines and objectives.

Assessment of Biodiversity Risk for Development/Construction Projects

Analysis and assessment of risks to biodiversity, according to PTT's biodiversity and ecosystem services management guidelines, are integral to every stage of project development, integrated into Environmental Impact Assessments (EIA). These assessments evaluate project risks to biodiversity and ecosystem services comprehensively, considering factors such as site location and size, proximity to protected areas, highly biodiverse locations outside protected areas, and distance from areas of high biodiversity. Additionally, data from the International Union for Conservation of Nature's (IUCN) Red List of Threatened Species are utilized to assess the risk of species extinction resulting from project activities. Systematic risk assessments enable PTT to develop preventive, corrective, and mitigative measures to compensate for potential biodiversity losses appropriately. These measures are tailored to the specific characteristics of the project and its development area. For example, measures may include minimizing disturbance by limiting the footprint area, restoring degraded areas to their original state, selecting transportation routes with minimal environmental disruption, and collaborating with wildlife experts to facilitate the relocation of wildlife if necessary. 

Assessment of Biodiversity Risk in Operational AreasGRI304-1,GRI304-2,GRI304-3,GRI304-4

PTT conducts comprehensive risk assessments on biodiversity at all operational sites in Thailand. These assessments analyze the potential impacts on biodiversity values in each area, considering factors such as proximity to conservation areas and the biodiversity significance of nearby regions. PTT identifies projects with high-risk levels, mandating the development of Biodiversity Action Plans (BAPs) to mitigate potential impacts on flora, fauna, and the environment.

Results from the assessments identified one high-risk area, the natural gas separation plant in Nakhon Si Thammarat province. Risk assessments cover species listed in the IUCN Red List and conservation status criteria established by the Department of Natural Resources and Environment Policy and Planning, e.g., Ratufa bicolor, Trachypithecus obscurus. BAPs have been completed, outlining action plans, objectives, timelines, and responsible entities at each stage to prevent adverse impacts on biodiversity, including staff training and community engagement. Additionally, risk assessments and BAPs are being reviewed for the natural gas pipeline transmission system's operational areas.

PTT encourages community and stakeholder involvement in providing feedback, expectations, and concerns regarding environmental impact assessments (EIA) reports, environmental protection measures, and BAPs through participatory activities or surveys during the environmental impact analysis process.

Key Projects/ Initiatives 

Biodiversity Data Survey 

PTT has embarked on comprehensive biodiversity surveys to evaluate the richness and distribution of flora and fauna surrounding its operational sites across Thailand. The primary aim is to gather and analyze baseline biodiversity data for each operational area and formulate environmental management plans aimed at rejuvenating, enhancing biodiversity, and safeguarding environmental quality. The surveyed organisms encompass a wide array, including avifauna, mammals, reptiles, amphibians, insects, fish, plants, and crustaceans. Following systematic assessments, specific areas were prioritized for scrutiny based on risk evaluations and community inputs. These included the natural gas separation plant in Khanom and the operational sites of OR, such as the Phuket Airport fueling station, petroleum depots in Songkhla, Nakhon Sawan, Saraburi, and Phitsanulok. The projects were conducted in collaboration with the Bird Conservation Society of Thailand (BCST), alongside participation from universities and non-governmental organizations (NGOs).

During surveys around the Khanom natural gas separation plant, a remarkable plant species, Microchirita involucrate (Craib) Yin Z. Wang var.gigantiflora C. Puglisi, endemic to the Khanom district in Nakhon Si Thammarat province, was discovered. Additionally, a novel moth species was found near the Saraburi petroleum depot, a species exclusive to Thailand, and scientifically named as Gatesclarkeana thailandica.

Moreover, PTT partnered with the Department of National Parks, Wildlife and Plant Conservation, Kanchanaburi Rajabhat University, and the National Science Museum to conduct biodiversity surveys in the areas of the natural gas pipeline transmission system in Kanchanaburi province. This initiative aimed to survey, analyze, and compile biodiversity data comprehensively. Subsequent to these surveys, environmental restoration measures were implemented, and continuous monitoring of progress ensued. The outcomes of these studies serve as invaluable tools for raising awareness among communities and stakeholders, facilitating future conservation efforts and biodiversity preservation endeavors.

Mitigation of Impacts during an Oil Spill Incident

For oil spill incidents, PTT and its subsidiaries have developed comprehensive management guidelines in collaboration with government agencies. These guidelines encompass strategies for mitigating impacts, closely monitoring potential effects on communities and the environment, and implementing both short-term and long-term restoration plans.

Regarding the natural gas and oil leakage incident from the Montara source, PTT Exploration and Production Public Company Limited (PTT) actively participated in crafting mitigation guidelines and provided support for scientific research aimed at monitoring long-term environmental impacts. These efforts were carried out by independent research units under the supervision of the Australian government. Furthermore, in 2022, specific guidelines were implemented to mitigate impacts and provide relief to those affected by the aforementioned oil spill incident.
