Climate Change

Supporting the SDGs Goals

Goal 7:

Affordable and Clean Energy

Goal 13:

Climate Action

Challenges and Opportunities

Climate change is a critical global issue primarily caused by greenhouse gas emissions from human activities, particularly the use of fossil fuels in the energy, transportation, and industrial sectors. These emissions contribute to global warming and have significant impacts on the environment, ecosystems, and the quality of life of people worldwide. Therefore, reducing greenhouse gas emissions while adapting to climate change is essential to mitigating its impacts and supporting long-term sustainability.

For the energy industry, climate change presents both business challenges and opportunities. Government policies promoting a low-carbon economy are encouraging organizations to transition toward greater use of clean and renewable energy, including solar, wind, and biomass energy. This transition creates opportunities for the Company to develop new technologies, expand investments in clean energy, and create additional value through the development of green energy projects.

Ratch Pathana Group places importance on reducing greenhouse gas emissions and promoting clean energy by increasing the proportion of electricity generated from renewable energy sources. These efforts aim to mitigate the impacts of climate change and support the goal of limiting the global temperature increase to no more than 2°C (2.0°C pathway) in accordance with the United Nations Framework Convention on Climate Change (UNFCCC), as agreed at COP21 in Paris under the Paris Agreement.

In addition, the Company has established a target to achieve Net Zero Emissions by 2050 to support the transition toward low-carbon business operations and strengthen the Company’s long-term competitiveness and sustainability.

Climate Change Management Targets

Short-term | Present-2030

Targets

Increase the proportion of electricity generation from renewable energy to 50% of total installed capacity based on equity proportion by 2030.
Reduce Carbon Emission Intensity per unit of electricity generated by 10% by 2030.

Key Measures

Develop and expand solar power and other clean energy projects.

Improve energy efficiency across production processes and operations.

Reduce waste generated from business operations to minimize waste sent to landfill.

Scope Coverage

Scope 1 and Scope 2

Long-term | 2041–2050

Target

Achieve Net Zero Greenhouse Gas Emissions by 2050.

Key Measure

Promote and support certified Carbon Offset activities in accordance with recognized standards to compensate for residual greenhouse gas emissions from business operations.

Scope Coverage

Scope 1, Scope 2, and relevant Scope 3 categories

Goal and Performance Highlights

In 2025, management continued to drive the implementation of its climate action plan with tangible and measurable progress, successfully achieving the following key targets:

Short-Term Target: Carbon Footprint of Product Registration

The Company successfully completed the registration of the Carbon Footprint of Product (CFP) certification for its electricity and steam products within 2024 (B.E. 2567), in accordance with the established target. This achievement represents a significant milestone in advancing environmental transparency, as the CFP certification enables the Company to comprehensively and credibly disclose greenhouse gas emissions across the full lifecycle of its products — consistent with international standards and the expectations of stakeholders across all sectors.

Outcome

Target achieved as planned

Long-Term Target: Expansion of Renewable Energy Generation

The Company had set a target to increase the proportion of electricity generation from renewable energy sources to at least 15% of total installed capacity based on equity interest by 2030 (B.E. 2573). Through its sustained commitment to accelerating the clean energy transition, the Company has already achieved a renewable energy share of 19% of total installed capacity based on equity interest — surpassing the target by 4 percentage points and delivering the result ahead of schedule. This outstanding achievement clearly demonstrates the Company's capability and momentum in driving a clean energy portfolio transformation.

Outcome

Target achieved ahead of schedule

Climate Change Governance

Ratch Pathana Energy Public Company Limited has established a systematic climate change governance structure across Board, management and operational levels to ensure the effective management of climate-related risks and opportunities in alignment with the Company’s strategy, risk management processes and performance monitoring.
