Environmental Management

Importance and Mission

PTTEP realizes the importance of compliance with relevant laws and regulations as well as responsibility for community, society, and the environment in all operating areas, to reduce both direct and indirect impacts on the environment (inclusive of spillage, climate change, biodiversity, waste, air pollution, and water resources). PTTEP has garnered stakeholders' trust and has embodied the values of responsible consumption of natural resources, environmental stewardship, conservation, and sustainable management.

PTTEP commits to operate business conscientiously and responsibly towards society and the environment by adhering to the Safety, Security, Health, and Environmental (SSHE) Policy which includes a commitment to environmental protection. Company personnel, business partners, and contractors working for or on behalf of the Company must abide by the SSHE Policy.  In alignment with the policy, the Environmental Management Strategic Roadmap is established to demonstrate PTTEP's commitment to achieve cleaner petroleum exploration and production with environmental stewardship. The roadmap also supports the company sustainability long-term strategy/target and the Company's environmental management requirement to achieve SSHE Target Zero. The roadmap defines the long-term environmental management plan to reduce environmental footprints with focus on carbon and ecological footprint, promote the circular economy concept and create positive environmental value. 

Moreover, PTTEP implements SSHE Management System (SSHE MS), which complies with the ISO 14001 international standard. PTTEP requires all operating assets to implement and certify the ISO 14001, which resulted in achievement of the latest ISO 14001:2015 certification for PTTEP's operating assets in Thailand, Myanmar, and Malaysia (Sarawak Project) from SOCOTEC certification (under United Kingdom Accreditation Service - UKAS). PTTEP develops SSHE Management System covered all activities in E&P phases; exploration, production, and decommissioning and major supporting activities; product transportation, waste management, logistics and supply chain management. For effective implementation, the corporate oversight of SSHE management system is in place which includes the requirement of SSHE due diligence process before, during and after a merger and acquisition (M&A) deal takes place, to ensure business partners' compliance with the Company's requirements.

PTTEP assesses each project's environmental risks against regulatory requirements, the Company's standards and/or international standards. Such environmental assessment is a tool to identify and evaluate environmental issues and impacts. It also helps in the setting of impact monitoring and mitigation plans. Throughout the company lifecycle, from exploration, production until decommissioning, PTTEP has followed all requirements specified in the Environmental Impact Assessment (EIA) and the Decommissioning Environmental Assessment (DEA) reports (which includes those relating to social and health issues). PTTEP takes priority of decommissioning activities at the same level of exploration and production activities, therefore SSHE MS has been adopted at same level. In 2021, PTTEP conducted the EIA in a total of 12 projects, comprising 2 exploration and development projects, and 10 production projects. The summary of the Company's EIAs and case studies includes in Related Documents.

Stakeholders also play an important role in driving business towards success and this demands appropriate management of their expectations and agreed objectives. Stakeholder management is conducted through the Company's stakeholder management process or the EIA or DEA process. The EIA and DEA reports contain concerns raised during the stakeholder engagement activities, as well as suggestions to prevent and mitigate possible impacts. Such concerns are analysed, to define appropriate measures. The stakeholder engagement activities will be arranged for all EIA and DEA projects.

Furthermore, PTTEP is committed to comprehensive reporting on environmental performance for all assets and petroleum support bases under our operational control. In 2021, Company achieved the group-wide coverage of environmental reporting at 100% and is in line with the Global Reporting Initiative's Sustainability Reporting Standards (GRI Standards), full reporting guideline on Oil and Gas Sector Disclosures (OGSD) for the "In Accordance - Core" option and the International Petroleum Industry Environmental Conservation Association (IPIECA)'s reporting guideline on international sustainability. The Company has continuously collected and reported the environmental performances via the web-based 'Environmental Performance System (EPS)'. This reporting covers energy consumption, greenhouse gas emissions, air emissions, water withdrawal, water discharge, spills, produced water management, waste management, hydrocarbon production, and environmental expenditure. The up-to-date data can be analyzed, to enhance environmental management efficiency and ensure compliance with relevant laws and the Company's regulations.

For continuous improvement of environmental performance, PTTEP has reviewed and improved data collection and database to ensure its timeliness. The data first collected in 2010 till now is verified by an external party and it has been publicly disclosed in PTTEP's annual Sustainability Report. In addition, PTTEP also benchmarks its performance on climate change and water security against peers in the International Association of Oil and Gas Producer (IOGP), Dow Jones Sustainability Indices (DJSI), CDP (formerly Carbon Disclosure Project), and other organizations.
