Environmental Improvement Roadmap for GHG Reduction

Scope of GHG Emissions of Corporate Activities

The amount of greenhouse gas emissions GHG (ton CO2e) in 2022

SCOPE 1 : Direct GHG Emissions

501 ton CO2e

SCOPE 2 : Energy Indirect Emissions

2,390 ton CO2e

SCOPE 3: Other Indirect Emissions of Greenhouse Gases

591 ton CO2e


176 ton CO2e

SCOPE 1 : Direct GHG Emissions

From activities within the organization, such as the incineration of machinery, the use of company-owned vehicles, the utilization of chemicals for wastewater treatment, and the occurrence of leaks or spills from processes or activities.

SCOPE 2 : Energy Indirect Emissions

The purchase of electricity, heat energy, and steam energy for use within the organization.

SCOPE 3: Other Indirect Emissions of Greenhouse Gases

Employee commuting using non-organization vehicles, traveling to off-site conferences, and the use of various materials and equipment contribute to the establishment of management guidelines for effective greenhouse gas emissions reduction. This applies to the levels of factories, industries, and the country as a whole. The benefits of conducting a Business Sector Carbon Footprint Assessment (CFO) include evaluating the amount of greenhouse gas emissions released from organizational activities and identifying significant causes of emissions. This assessment helps identify strategies to reduce the organization's greenhouse gas emissions and may involve implementing carbon offset activities. The government can utilize such assessments as a guideline to drive the management of greenhouse gas emissions for the collective benefit of the country.

Waste Management

Waste Management

Waste Recycle 3,366 Kg (8 Month)


5,508 KgCO2e

Action Plan for 2022

Sorting and disposing of waste as required by law; promoting reuse and recycle.


Continuing with the goal of waste sorting and recycling not less than 2022 and extending recycling into CSR activities.

2022 Performance

Perform waste sorting and collecting data through the GEPP Sa-Ard, waste can be sorted and used for further utilization of 3,366 kilograms, representing a recycling proportion of 23.58%, equivalent to a greenhouse gas reduction of 5,508 KgCO2e

Solar Rooftop Project to install solar panels on the roof of office buildings and toll plaza buildings

The Company has studied and found that there is an area where solar rooftop can be installed approximately 380 KWp, which can produce electricity of 484,900 KWh/Year, and thus conserve energy consumption by more than 25-30%. The Company has a 2-phase investment plan. The first phase is installed at the office building and toll plaza at Don Muang, with production capacity of approximately 200 KWp, and is expected to be installed in July 2023. The second phase is installed at the toll plaza building and the remaining 8 toll plaza buildings for another 180 KWp by 2023, representing a reduction in greenhouse gas emissions of 225 tonCO2e/Year This project will be certified by T-VER, which is Thailand Voluntary Emission Reduction Program, a project to reduce greenhouse gas emissions that the Thailand Greenhouse Gas Management Organization (TGO) developed to promote and support all sectors to voluntarily contribute to the reduction of greenhouse gases in the country.

Action Plan for 2022

Study, design, evaluate the suitability and cost-effectiveness of Solar Rooftop installation at office buildings and toll plaza buildings.


Installation of Solar Rooftop approximately 380 KWp, which can generate electricity of 484,900 KWh/Year, and thus save electricity consumption by 25-30%, equivalent to GHG reduction of 225 tonCO2e/Year

2022 Performance

The study is complete and is currently in the process of installing phase 1, installation at the office building and the Don Muang toll plaza building. The production capacity is approximately 200 KWp and is expected to be completed in July 2023. Phase 2 will be installed at the toll plaza building and the remaining 8 toll plaza buildings, with another 180 KWp within 2023.

Test of Replacing Combustion Engine with Solar Cell Energy

The Company has replaced engines of surveillance vehicles with energy from solar cell. In the case of parking with engine running 4 hours a day, 6 litres of fuel are consumed. A vehicle is used 300 days a year (diesel price is 35 Baht per litre as of June 2022); fuel consumption is reduced 1,800 litre per year or 63,000 Baht per year. CO2 gas is reduced by 2.745 Kg. or approximately 5,000 Kg.CO2per year. As a result, the Company reduces its expenses by 63,000 Baht per year (paid off in 1.3 years). Carbon Footprint is reduced by 5 tons per year.

Carbon credits: can be sold to offset the Company’s greenhouse gas emissions, creating a good image for the organization.

Action Plan for 2022

The Company studies and tests to use solar cell energy to replace the engine in the surveillance vehicles

  • Fuel consumption is reduced by 1,800 litre, or 63,000 Baht per year.
  • CO2 gas is reduced by approximately 5,000 Kg.CO2 per year
2022 Performance

Tested for 3 months and saved 76.92 litres of fuel, an average of 25 litres per month. A total of approximately 800 Baht per vehicle per month.
*Remark: savings depend on engine-off period and use of solar energy.

Solar panel equipment for emergency calls on the way

Installed a solar-powered emergency phone To replace the old equipment that has been in use for more than 25 years, 99 sets of emergency telephones have been replaced on the road with GSM and solar energy.

Using and servicing electric vehicles (EVs)

The company has installed a 50KW DC Fast Charge charging station that can be charged to full capacity within 1 hour and changed the executive car to an EV.

Pollution and Waste Management

The Company has monitored and measured pollution values from operations by a legally authorized measurement agency to control in accordance with the law. The measurement results are as follows:

The quality of air pollution measured by 3rd parties is within the standard.

Trial test installation of Solar Cell instead of engine


Study, research and experiment on forming dust from vacuum sweepers mixed with plastic waste. Used as decorative materials and paved walkways in collaboration with Plastic Institute, Zero West Yolo Co., Ltd. and GEPP Clean Co., Ltd.

Measure air quality in general by collecting air samples with High Volume Air to analyze the concentration of dust particles up to 100 microns in size for 24 hours at a location in front of the toll booths.

The Company measures the cumulative average noise level throughout the operation, in which working period of employees per shift is 8 hours

Manage waste by separating and disposing of waste according to the laws, as well as promoting reuse and recycle, such as recycling toll receipts and unused paper into Green Way notebooks and donating them to underprivileged schools throughout the country. The Company cooperates with GEPP Sa-Ard, a start up for waste management, in which 3,366 kilograms of waste can be sorted and reused, representing a 23.58% recycling rate, equivalent to a reduction in greenhouse gas emissions of 5,508 KgCO2e (for a period of 8 months). The implementation of sustainable waste management is upgraded with the goal of Zero Waste to Landfill

Monitoring effluent values to be in compliance with the standards defined by the laws on a yearly basis. In 2022, effluent values were measured at the Head Office and Din Daeng Toll Plaza. The results of both locations are consistent with the laws.
