Remark : * The Emission Factor values applied in this assessment are based on the announcement by the Thailand Greenhouse Gas Management Organization (Public Organization) (TGO) (April 2022). For energy consumption data from the district cooling system at Suvarnabhumi Airport, the Emission Factor provided by District Cooling and Power Plant Company Limited (DCAP) has been applied. The greenhouse gas emissions assessment of AOT is conducted under the Operational Control boundary-setting criteria within the scope of airport operations
Remarks:
*AOT does not employ persons with disabilities or individuals from underprivileged groups. Instead, the company contributes to the fund in accordance with the Persons with Disabilities Empowerment Act B.E. 2550 (2007).
**In fiscal year 2024, the training curriculum was revised from four programs to five programs.
***Data will be available for entry at the end of fiscal year 2025 (September 30, 2025).
