Remark:
GHG Data is reported on calendar year basis, based on GHG Protocol Corporate Accounting and Reporting Standard. Only carbon dioxide is included in scope of calculation, no biogenic CO2 emission included in AOT operations. Emission factor is sourced from Thailand Greenhouse Gas Management Organization (January, 2017), U.S. Environmental Protection Agency (EPA), and Intergovernmental Panel on Climate Change (IPCC). AOT applies 100-year global warming potential, referenced from IPCC Fourth Assessment Report (AR4 - 100 year) (AR4 – 100 year) as the emission factor.

| GRI 303-5 DJSI 2.4.2 |
Water consumption4 | Thousand m3 | 5,889 | 4,755 | 4,783 | 7,521 | 9,689 |
Remark:
Effluent data cover six airports, excluding the Head Office. The effluent data collection is based on water consumption invoices and internal water circular gauges.
1 All water withdrawal and discharge was freshwater, at ≤ 1,000 mg/L total dissolved solids.
2 According to World Resources Institute’s Aqueduct Water Risk Atlas, Suvarnabhumi Airport and Chiang Mai International Airport are located in extremely high water-stressed areas. The majority of water supplied by public utilities are sourced from surface water.
3 Water discharge equates the amount of water entering water treatment facilities, which was treated according to environmental impact assessment standard. There was no incidents of non-compliance with discharge limits in the reporting period.
4 Water consumption equates the difference between water withdrawal and water discharge. AOT has no significant water storage with significant impact on nearby water use.

Remark:
From 2020 onwards, waste data is based on GRI 306 (2020): Waste. Waste data in 2019 with uncategorized recovery or disposal method was assumed to use the majority’s method.
5 All waste recovery has been done outside AOT premises (Off-site).
6 Waste disposal process follows Thailand’s environmental regulation and environmental impact assessment. The waste disposal process of general waste follows regional procedures. All waste disposal processes has been done outside AOT premises (Off-site).
7 Other disposal methods for general waste were such as being sent to be managed by third-party according to the regulations.
8 Other disposal methods for hazardous waste included incineration without energy recovery and landfill.
