Environmental Stewardship

Environmental Stewardship

EGAT has undertaken its mission in an environmentally responsible manner to ensure the sound environmental practices are in full compliance with all applicable laws and regulations. EGAT has continuously implemented environmental management systems according to the international standards, such as conducting Environmental Impact Assessment (EIA) reports in order to prevent and mitigate environmental and social impacts. The key environmental issues taken into consideration are as follows:

Study of Environmental Impact of Power Plant Development Projects

  • Environmental report for Lamtakong Dam Hydropower Plant with the installed capacity of 1.5 MW

Greenhouse Gas Management

Realizing the importance of greenhouse gas management, EGAT has prepared the work plan of greenhouse gas reduction and monitoring. In 2022, EGAT has set up a working group to mobilize the strategy of EGAT carbon neutrality to achieve low carbon organization by 2050, to build sustainable energy security, and to take part in mobilizing greenhouse gas reduction in response to the government policy.

EGAT has quantified the greenhouse gas emissions of the organization (corporate carbon footprint) in accordance with ISO 14064-1: 2018 covering EGAT’s operational areas, such as power plants, mine, dams, offices, and transmission system. In 2022, the direct greenhouse gas emissions from the organization’s activities and the indirect emissions from energy use (types 1 and 2) amounted to approximately 32.93 MtCO2e. Moreover, the information on greenhouse gas emissions from the electricity generation process was used in the eco-efficiency assessment as guidelines for sustainable production and consumption.

In 2022, EGAT’s goal of greenhouse gas reduction was 4.5 MtCO2. From the operation throughout the year, EGAT could decrease greenhouse gas emissions of 8.38 MtCO2 (from the preliminary assessment) resulting from three measures comprising electricity generation from renewable energy, efficiency increase in electricity generation, and standard criteria and No.5 labeling. EGAT’s measurement, reporting, and verification (MRV) has been endorsed by the EGAT Committee on Greenhouse Gas Management before being annually proposed to the Energy Policy and Planning Office for conducting the country report.

Environmental Quality Monitoring

EGAT has a strong determination to adopt measures to prevent and control the environmental impacts which might occur as a result of EGAT’s operation, in particular the organization’s emissions to the air such as sulfur dioxide (SO2), nitrogen oxides (NOx), and carbon dioxide (CO2). Moreover, EGAT continuously monitors the noise level, water quality, water ecosystem, quality of life, as well as garbage and waste management. Discharges to the water have been managed in compliance with all applicable environmental laws including the improvement of the overall environmental quality.

Sustainable Resource Use

EGAT continues to pursue clean and green energy sources by promoting the development and consumption of renewable and alternative energy, ranging from hydropower, wind, solar, geothermal, and biomass. In 2022, a total net energy of 14,688.35 million kWh from clean energy sources was produced in EGAT’s power generation system.
