The Committee also provides directions, monitors implementation, and evaluates performance on sustainability-related matters.
Environmental Management System
PTTEP implements Environmental Management System as part of the PTTEP SSHE Management System (PTTEP SSHE MS), designed in alignment with international standards, including International Association of Oil and Gas Producers (IOGP) guidelines and ISO 14001:2015.
This system is implemented across all operated assets, covering all activities in E&P phases including exploration, production, and decommissioning and major supporting activities, product transportation, waste management, logistics and supply chain management. To ensure effectiveness and compliance, the system is externally verified by accredited third parties. PTTEP has obtained ISO 14001:2015 certification from SOCOTEC (accredited by the United Kingdom Accreditation Service) for operations in Myanmar, Malaysia, and petroleum support bases in Songkhla and Ranong. In Thailand, all operational areas are achieved the ISO 14001:2015 Attestation (assessed against ISO 14001:2015) at a reasonable assurance level by LRQA (Thailand) Limited.
In addition, to ensure effective integration during mergers and acquisitions (M&A), PTTEP’s oversight of SSHE management system is implemented, including the requirement for an SSHE due diligence process before, during and after a merger and acquisition (M&A) transaction, to ensure business partners' compliance with the Company's requirements.
Environmental Risk Management
PTTEP conducts Environmental Assessment Report for each petroleum development project in accordance with applicable laws and regulations of host countries, Company standards, international standards, and stakeholder inputs. Environment Assessment, including social and health issues, serves as a key tool to identify and evaluate environmental issues and potential impacts under both normal and abnormal conditions across all project phases, including exploration (including seismic), production, and decommissioning. Mitigation and monitoring measures derived from Environmental Assessment Report are legally binding and strictly implemented.
Stakeholder engagement is an integral part of the environmental assessment process. Feedback, including concerns and recommendations on impact prevention and mitigation, is gathered through engagement and survey processes. These inputs are analyzed and incorporated into environmental mitigation and monitoring measures to address stakeholder expectations, particularly those of local communities. PTTEP also continuously engages with regulatory authorities and academic institutions/organizations for consultation on specific environmental matters to enhance environmental management practices beyond regulatory requirements. The summary of the Company’s EIAs and case studies are included in Related Documents.
Furthermore, the Company annually assesses environmental risks that may impact its operations and manages those risks to remain within acceptable levels in accordance with the Enterprise Risk Management framework. The assessment results are used to establish management and mitigation plans for key environmental issues, including climate change, biodiversity and ecosystem services, water resource management, and waste management.
