Management Guidelines and Practices
BEM operates in compliance with its Environmental Policy covering climate-related issues.
Accordingly, the Company has determined climate change and energy management goals and strategies covering all activities across the supply chain in order to achieve aligned and effective implementation of GHG reduction efforts. The Company has established the Quality Management System Committee, the Safety Committee, and the Quality and Efficiency Management Committee to supervise internal quality and environmental management. The Energy Management Working Group has also been appointed to oversee and carry out operations to reduce GHG emissions and consumption of energies, such as fuel, electricity, water, and paper.
In 2025, BEM completed the verification of its GHG emissions, covering all three scopes. The organizational boundary established for calculating and reporting these emissions accounts for 99% of total operations, excluding the office areas of the Company’s subsidiaries. This verification was conducted by an external auditor, TUV NORD (Thailand) Company Limited (TUV NORD). The Company also registered its corporate GHG emissions certification with the Thailand Greenhouse Gas Management Organization (Public Organization) (TGO). Notably, the Company does not engage in activities or operations of assets held within a Real Estate Investment Trust (REIT) portfolio.


Impact on Business and Stakeholders
The impact of climate change, such as global warming, disasters, and floods, has led to the loss of natural balance and damage to living things, homes, and infrastructure. For this reason, both public and private organizations over the world are obliged to take measures to mitigate climate change, such as issuing carbon tax or inventing greenhouse gas (GHG) emissions capture technology, which must be closely monitored by BEM. Therefore, if BEM lacks effective climate change mitigation and adaptation measures, it will face increased risks, such as high energy costs and higher costs from damage to infrastructure due to extreme weather events, which may even cause delay or disruptions to business operations. As a result, the Company may lose the confidence of communities, society, suppliers, and investors.
Commitment, Challenges and Opportunities
BEM's businesses, especially the rail business, which consumes high amount of energy to operate and thus indirectly contribute to GHG emissions.
Therefore, the Company strives to reduce energy consumption by optimizing the efficiency of eco-friendly tools, equipment, and technology employed in business operations. The Company also promotes the use of renewable energy by setting a policy and reviewing relevant goals every year, in order to be a guideline for managing the company in the same direction, including raising employee awareness, and promoting projects, activities, and measures essential to the achievement of the Net Zero GHG Emissions Target by 2050. This is in line with and responds to the expectations of investors and other stakeholders. It also mitigates future climate-related risks and demonstrates the Company's responsibility towards government agencies, communities and society while encouraging customers to use low-carbon transportation services.
BEM is committed to aligning with the Paris Agreement and the 26th session of the Conference of the Parties (COP26) to the United Nations Framework Convention on Climate Change (UNFCCC), which aims to limit an increase in the global temperature to 1.5oC. This includes actions to reduce GHG emissions, with the target of achieving net zero GHG emissions by 2050.
BEM has established a GHG emissions reduction target-setting process in accordance with the Science Based Targets initiative (SBTi). This process began by calculating the Company’s current GHG emissions, using 2023 as the base year, which recorded a total GHG emissions of 143,834 tCO2e. In 2023, working with relevant departments, the Company developed a strategic plan to set GHG reduction targets by adopting an operational control approach, covering all three scopes of GHG emissions, while collecting relevant primary data to assess and calculate its corporate GHG emissions.
Targets and Performance Indicators
Overall, BEM achieved a 5.59% reduction in GHG emissions, which fell short of the set target. However, Scope 1 GHG emissions were successfully reduced by 64.00%, meeting the target due to the company's initiatives to cut fuel consumption by gradually replacing internal combustion engine vehicles to electric vehicles. Meanwhile, Scope 2 GHG emissions decreased by 1.11% and Scope 3 GHG emissions dropped by 5.80%. Although these volumes represent a decline from the previous year, they fell short of the established targets because the operational plans to install solar power generation systems remain underway and have not yet been completed consequently of non- renewable energy consumption for 2025 decreased by 0.90%, which also did not meet the designated target.
