GHG emissions, using operational control basis: • Direct GHG emissions (Scope 1): Sources in 2021 include fuel consumption, methane emissions from septic system and activated sludge wastewater treatment, and refrigerants (R134a). In 2021, the acquisition of R22 accounted for GHG emissions of 11 tonnes CO2 equivalent. • Indirect GHG emissions (Scope 2): Sources in 2021 include electricity consumption. • Other GHG emissions (Scope 3): Sources include employee business travel by car managed by third party, and purchase goods and services such as paper and water. • GHG emissions calculation is based on the latest emission factors (EF) from Thailand Greenhouse Gas Management Organization (Public Organization) (TGO). The calculation methodology is based on Operational Control Approach, with the Thai Carbon Footprint Organization (CFO) quantification standard by The Thailand Greenhouse Gas Management Organization (Public Organization). 2. GHG saving from recycled paper managed by 3rd party in 2021 was 8.3 tonnes CO2 equivalent. 3. Energy consumption: Scope 1 energy consumption covers fuel for both stationary combustion (i.e. diesel for generators and fire pumps) and mobile combustion (i.e., diesel and gasoline for Bank’s vehicles for executives and vans). Electricity data is collected from the Headquarters and branches where the electricity bills and payments are directly managed by the Corporate Property and Services Department. 4. Water withdrawal: Water withdrawal data is collected from the Headquarters and branches where the water bills and payments are directly managed by the Corporate Property and Services Department. According to Metropolitan Waterworks Authority, the water station that provides water for the Bank’s Head Office has the TDS value 390 mg/L (as of 31 December 2021) which is considered as freshwater (TDS < 1,000 mg/L). According to WRI’s Aqueduct Water Risk Atlas, the Bank’s Head Office is located on a water stressed area level medium-high (20%-40%). 5. Waste generation: ttb started collecting general waste data during 2019 at the Headquarters. General waste comprises only food waste diverted from disposal offsite by other recovery operation, i.e., animal feeds. 6. Recycled waste comprises only paper waste sent for recycling. Paper waste is collected by a third-party service provider (diverted from disposal offsite) and the weight of paper recycled is provided in the paper shredding report. 7. Paper usage: The amount of paper usage in the operation is tracked from the purchase. Paper usage data is collected from the Headquarters and branches where the paper bills and payments are directly managed by the Corporate Property and Services Department. 8. Business travel: The GHG emissions from ttb’s fleet vehicle is calculated based on the amount of fuel consumed (litres) multiplied by the emission factor (kg CO2 e/litre). The emission factor is based on Thailand Greenhouse Gas Management Organization (Public Organization) (TGO) version 2021. The distance of business travel using external party transportation is derived from travel reports provided by the external party transportation provider. 9. NR means not reported; NA means not available.
