Environmental Dimension Targets

Operational Eco-Efficiency

Bangchak determined to emphasize the efficient use of natural resources in its production process, the highest production capacity but the least waste and pollutions. The company has also adopted the environmental management system into use. The system is in accordance with ISO 14001: 2015 regarding the use of natural resources and pollution control to drive for continuous development under proactive policies in compliance with the Green Industry Level 5: Green Network, and promoted environmental management practices to all stakeholders throughout the supply chain, communities and consumers in order to become a green network. This too, demonstrated the company’s commitment to environmental development which is becoming the corporate culture in doing business with social responsibility today.


Bangchak realizes the importance of balancing economic growth and environmental impact in pursuing for sustainable development and determined to uses eco-efficiency as an indicator. By which, the company uses earnings before interest, tax, depreciation and amortization (EBITDA) to reflect economic growth and uses the amount of GHG emission which is an important environmental aspect of the petroleum industry to reflect the environmental impacts. A high ecoefficiency value indicates high efficiency production and low environmental impacts.

Note: EBITDA and carbon dioxide equivalent (scope 1 and 2) of the refinery and market businesses.

Energy Consumption

Energy is an essential input driving businesses and the production process of various industries. However, energy consumption contributes to climate change impacts from greenhouse gas (GHG) emissions. Global businesses are aware of this fact and determined to set up their target for sustainable development in alignment with SDG 7 & SDG 13 to help reduce the adverse impacts of energy consumption and GHG emissions.

Bangchak has recognized the importance and impacts of energy consumption in business operations and taken into consideration the establishment of energy management system in accordance with ISO 50001 for the refinery business and oil distribution terminal since 2014. In 2019, the company was the first company in Thailand certified by ISO 50001: 2018. This proves the true commitment of the company and its capability in energy management in line with international standards and to be the foundation for sustainable growth in the future.

Bangchak Group is ready to drive the development of the Low-Carbon Society with the BCP NET Plan comprising

4 Dimensions

in order to achieve organizational

Carbon Neutrality by 2030 and Net Zero by 2050

emphasizing tangible processes and long-term results.

Eco-Friendly Transportation

Project to Increase Proportion of Oil Transportation by Semi-Trailer

The company manages transportation vehicles by changing from 2 single trucks to a semi-trailer (40,000 liters load). This change helps reduce not only the cost of transportation but also the GHG emissions per unit of oil.

The proportion of refined oil transportation by trucks decrease the GHG emissions

(Target: Using semi-trailer increase 2% per year and and decrease the amounts of transportation for reducing greenhouse gas emission.)

Water Consumption

Bangchak, as one in the energy industry consuming high quantity of water, recognizes the importance of water management as well as the increase in efficiency improvement of water consumption. Therefore, the company set targets for the reduction and control of new water withdrawal, including water management through the use of innovative tools and technology.In addition, the company uses Water Stress Index (WSI) of 25 Watersheds level in Thailand and the world class WSI(1) to assess the water scarcity footprint of the company’s products in accordance with ISO14046 guidelines.

Reduction of Water Consumption

Wastewater Management

In addition, the company sends water samples for regular analysis to the Department of Industrial Works and internationally certified ISO/IEC 17025. There are also dedicated personnel like the pollution controller to closely supervise the treatment system.

the company has also installed a special tool orequipment (COD Online) that shows real time results to theManufacturing Department and the surrounding communities.

Oil and Chemical Spill Management

Bangchak is aware of the risks and adverse impacts of oil and chemical spills from the business operations which were our materiality topics. Therefore, Bangchak prioritizes safety in every business operation and environment protection in every business activity to prevent oil and chemical spills affecting society and environment throughout the value chain: from crude oil transportation to our refinery, from oil product transportation to our oil depot and terminals, and from service stations to our customers.

Air Emissions Management

Air pollution is an important environmental issue for the energy industry since it is harmful to human health and affect quality of life of people in the society. This is especially relevant nowadays on the issue of particulate matter with 2.5 micron in size (PM 2.5) which has become a serious environmental issue in Thailand. Therefore, Bangchak takes careful steps to monitor and control the quality of air emissions emitted to the environment in order to prevent and mitigate impacts on employees, contractors working at Bangchak refinery, communities and environment around the Bangchak refinery and other operating sits of the company.

Biodiversity and Forest Management

Rapid economic growth in recent years has led to the use of natural resources and disturbance in natural ecosystems. It can result in biodiversity losses and habitat destruction for living organisms and ecosystems, which can have negative consequences on human quality of life, such as a decrease in food sources, and impacts on economic activity, such as decreased productivity. Bangchak Company is aware of both positive and negative effects on biodiversity from its business operations by making biodiversity an essential issue in the Sustainable Policy.

Environmental Cost Accounting

Bangchak has prepared and developed Environmental Cost Accounting, embracing oil refining processes, Bangchak Oil Depot, and Bang Pa-In Oil Depot. Such accounting has been publicized to external agencies and investors through its quarterly MD&A articles and IR Newsletters. In addition, knowledge of it has been constantly transferred to students and other interested agencies.
