Managing for Sustainability
Building a Sustainable Future Together. The Group believes that true business growth must be harmonized with the creation of global value. Beyond profitability, the Group’s core mission is to foster positive social and environmental impacts simultaneously. The Group has established a Sustainability Framework that is embedded in its corporate DNA, serving as a vital roadmap for driving the business toward sustainability across all dimensions:
With this framework in place, we are well positioned to become a leader in modern, environmentally friendly alternative energy, delivering maximum value fairly to all stakeholders and working together to build a better future for our planet.
The Group has integrated its sustainability commitment into the core of its business operations. This is executed through three primary strategies, known as the 'Triple-E Strategy,' ensuring that every step taken is a deliberate move toward a truly better and more sustainable world.
- Transitioning to renewable and clean energy in operations to reduce direct greenhouse gas emissions from the organization's activities and production processes.
- Enhancing energy efficiency to significantly reduce negative environmental impacts.
- Collaborating with stakeholders across the value chain to comprehensively promote low-greenhouse gas practices.
- Implementing rigorous verification and validation of greenhouse gas emissions, alongside transparent and auditable data disclosure.
- Research and development, including the application of advanced energy storage solutions in operations, utilizing environmentally friendly and sustainable materials.
- Driving innovation in new-generation electric propulsion technologies and high-efficiency battery technologies to achieve cost reduction and operational efficiency goals.
- Strategic investment in clean technologies and emerging innovations, such as Waste-to-Energy technology, clean hydrogen production, and Power-to-X technology, to accelerate greenhouse gas reduction and support the transition to a low-carbon society.
- Integrated and comprehensive development of an environmentally friendly value chain, from the upstream production of clean energy to the downstream use of products and services.
- Promoting community and stakeholder engagement through sustainable development projects to support carbon credit generation and drive shared, environmentally friendly growth.
The Group is firm in its belief that business growth must coexist in harmony with environmental stewardship and social responsibility. To reflect this commitment, the Group prioritizes sustainability management across all dimensions of its operations. The Group has established a comprehensive Sustainability Policy that serves as the definitive framework for its business conduct.

Biodiversity Management
Goals
Management Approach
Clear policies and operational mechanisms are fundamental to effective biodiversity conservation. The Group has adopted a suite of policies and commitments as the governance framework for the protection and sustainable stewardship of natural resources, with a focus on minimizing adverse impacts from business activities. The Group has operationalized the following two core policies in a manner appropriate to its business context:
The Group mandates biodiversity consideration and assessment at every stage of its operational processes. Biodiversity studies are conducted at high-biodiversity project sites to inform impact mitigation planning prior to commencement of activities. The Board of Directors, management, and all employees are required to acknowledge and strictly comply with these policies. Performance monitoring is conducted at least annually to ensure alignment across the organization.
Governance Structure, Roles, and Responsibilities
Governance and Risk Integration
The Group's biodiversity management approach is systematically integrated into the Enterprise Risk Management (ERM) framework, ensuring that nature-related risks are identified, assessed, and managed with the same standard and consistency applied to other material business risks.
Responsible Committees and Oversight

Biodiversity Management Process
Biodiversity Risk Assessment and Disclosure
The assessment employs globally recognized tools, including the WWF Biodiversity Risk Filter for portfolio-wide risk screening and hotspot identification.
The ENCORE (Exploring Natural Capital Opportunities, Risks and Exposure) tool is applied to assess the Group's business dependencies on ecosystem services. The assessment covers the direct operations of renewable energy power plant projects in Thailand — the primary activities with direct land and ecosystem interactions. Upstream value chain assessment focuses on Operations and Maintenance (O&M) suppliers, while the downstream assessment acknowledges material interactions with electricity transmission systems via substations operated by government authorities.
The assessment identified that our business has multiple dependencies on an ecosystem, particularly climate stability, which is derived from the climate regulation function of natural systems. This is critically important for maintaining consistent wind patterns and surface water availability, both of which are essential for cleaning solar panels and sustaining optimal generation efficiency. Material Impacts identified for ongoing vigilance include wildlife hazard risk, primarily arising from bird and bat collision risk with wind turbines, flagged as high reputational risk sites due to their proximity to conservation areas and Key Biodiversity Areas (KBAs).
The Group is committed to leveraging these assessment findings as the foundation for the continuous development of strategies and impact mitigation measures. The next phase will involve site-specific deep-dive assessments at highest-risk sites using the Integrated Biodiversity Assessment Tool (IBAT), leading to the development of tailored Biodiversity Action Plans (BAPs).
Application of the Mitigation Hierarchy Principle
In pursuing environmentally responsible and sustainable business operations, the Group has adopted the Mitigation Hierarchy as the guiding principle for biodiversity management, with a systematic and comprehensive focus on preventing and minimizing adverse impacts from operational activities across all stages. This principle comprises the following key steps:
Performance
Biodiversity Risk Assessment
The Group’s 2025 biodiversity risk assessment focuses primarily on the direct operations of its renewable energy business. This scope encompasses 8 wind power projects and 4 solar power projects located within Thailand. The total assessed area, including operational sites and adjacent buffer zones, covers 1,315 hectares across 182 assessed points. Furthermore, the assessment extends to the value chain, featuring a qualitative evaluation of Operations and Maintenance (O&M) suppliers. It also includes an analysis of the national grid connection within the downstream value chain. The Group is committed to expanding this assessment to cover the entire value chain in the future.
