WHA Group is committed to conducting business while creating sustainable growth with all stakeholders by giving importance to environment, social and good governance practices. One of the key issues that the Company determines to achieve is to accelerate sustainable climate change action to solve greenhouse gas and global warming issues by reducing greenhouse gas emissions as well as building important infrastructures such as promoting the use of renewable energy and using relevant technologies and innovations throughout the Group's value chain. This ambitious actions will be in line with global trends in responding to climate change issues including Thailand's goal of achieving carbon neutrality by 2030 and net zero greenhouse gas emissions by 2050.

To develop a net zero roadmap, WHA Group has initiated the following climate-action interventions through its core business operations such as developing and constructing new project focusing on resource efficiency. Moreover, the Group pushes to reduce energy consumption from sources that generate greenhouse gases as much as possible by promoting the use of renewable energy with the accomplishment to increase production capacity of solar rooftop totaling of 311 megawatts in 2023. The Group is also committed to reducing its dependence on natural resources through the water reclamation projects which directly reduces the use of raw water from natural sources and also established a long-term target to double water reclamation capacity from 30,200 m3 per day in 2020 to 60,400 m3 per day by 2027.

WHA Group also committed to achieving net zero emissions target by 2050 in line with the Science Based Targets initiative (SBTi). Therefore, we set short-term and long-term emission reduction targets linked to our net-zero commitment according to the SBTi guidelines as follows:

SHORT-TERM EMISSION REDUCTION TARGETS

• Absolute greenhouse gas emission reduction target (Scope 1 and 2) by 18.7 by 2025 from the base year 2021.
• Greenhouse gas emission intensity target per total revenue and share of profit (Scope 1 and 2) to be 1.45 tCO2e per 1 million THB of total revenue and share of profit by 2025 from the base year 2021.

LONG-TERM EMISSION REDUCTION TARGETS

• Absolute greenhouse gas emission reduction target (Scope 1 and 2) by 42% by 2030 and by 90% by 2050 from the base year 2021.
• Greenhouse gas emission reduction target (Scope 3) by reducing intensity emissions for investments by 74% by 2030 and by 90% by 2050 from the base year 2021.

We also commit to seek validation to these targets by the SBTi within 2025.

Greenhouse Gas Emissions

Remarks: *The company is in the process of registering for Renewable Energy Certificates (RECs), which is expected to be completed by the third quarter of 2025. Once completed, the company will be able to use the certificates to reduce its indirect greenhouse gas emissions (Scope 2) to zero or the minimum level, in accordance with the calculation methodology outlined in the GHG Protocol Scope 2 Guidance (Market-based Method). / **Please note that Scope 3 emissions for the year 2021 include data from only categories 1, 3, and 5. For the year 2022, 2023 and 2024, please refer to the detailed breakdown in the table below.
