ESMS Management Structure
Environmental and Social Management System (ESMS)
RATCH Group Public Company Limited (The Company), with an emphasis on sustainability, strives to uplift environmental and social operations - the materiality of electricity generation which is the Company's core business. RATCH hence implements the Environmental and Social Management System as a tool to support the environmental and social operations throughout the business life cycle towards the achievements of the objectives and goals efficiently and strengthens corporate creditability.

The Environmental and Social Management System Manual is written in line with international practices which are: International Finance Corporation (IFC) Performance Standards; Equator Principle (EP4); Asian Development Bank's Safeguard Policy Statement 2009; and International Standard of Organization (ISO) 14001:2015 and 45001:2018 which outlined management system for environmental, occupational safety and social risks caused by the Company's operations.
To put the Environmental and Social Management System (ESMS) into action, RATCH proclaimed the Environmental and Social Management System on 7 August 2024.
The ESMS structure consists of the Environmental and Social Management Committee (high-level executives); the Environmental and Social Management System Manager; the Environmental and Social Management System Working Team; the Environmental and Social Management System Internal Audit Committee with clearly-defined roles and duties of responsible persons. The system is integrated into power plants’ environmental departments, in order to drive and monitor the overall performance.
