Energy Conservation and Environment Protection
Energy-Saving Achievements
In conjunction with the targets of Taiwan’s Pathway to Net-Zero Emissions in 2050, the Bank passed the review of the SBT carbon reduction targets in March 2024, with 2020 serving as the baseline year. The greenhouse gas inventory Category 1 and Category 2 adopt an absolute reduction method, with a target of reducing carbon emissions by 42% by 2030. If the yearly carbon reduction target is not met, the Bank will purchase T-RECs for renewable energy and use self-sufficient solar power to make up for the shortfall. The greenhouse gas inventory covers all domestic business locations, overseas branches, subsidiaries and subsubsidiaries, which is aligned with disclosure in the financial statement. We are committed to promoting various carbon reduction measures in our own operations and expanding the use of renewable energy to move towards the goal of net zero.
Greenhouse Gas Reduction and Managemen
TBB started conducting ISO14064-1 greenhouse gas inventory and obtaining third party certification since 2018. Early inventories from 2018 to 2020 covered the head office building. To monitor carbon emissions across the entire bank, the scope of inventory was extended to cover all domestic locations, and overseas branches and subsidiaries from 2022.
Carbon Reduction Target
Short - term：
4.2% carbon reducing across the bank in 2024 compared to 2023.
Medium-term：
42% carbon reducing across the bank in 2030 compared to the base-year(2020).
In 2024, a total decrease of 30.49% compared with the 2020 base year, reaching the carbon reduction target for that year.
Long-term：
Adjust carbon reduction targets on a rolling basis based on the carbon reduction results in 2030.

Note:
- The emission factor refers to greenhouse gas equivalent = activity data × emission factor × global warming potential. Purchased electricity: calculated using the 2020 electricity carbon emission factor of 0.502kg CO2e/kWh announced by the Bureau of Energy. Refrigerant (including chillers, refrigerators, drinking fountains, etc.): greenhouse gas equivalent = original volume × dissipation factor × global warming potential. The equipment dissipation factor is derived from the 2006 IPCC Guidelines for National Greenhouse Gas Inventories, volume 3, chapter 7, table 7.9. The median value was adopted as the dissipation factor.
- The greenhouse gas emission factor for gasoline (official vehicles), diesel (emergency generators), and natural gas (employee cafeterias) was calculated based on the Greenhouse Gas Emission Factor Management Table (Version 6.0.4) of the Environmental Protection Administration, Executive Yuan.
- The global warming potential (GWP) was based on the GWP value in the 4th Assessment Report of the IPCC (2007) in which CO2=1, CH4=25, N2O=298, SF6=22,800, and HFCs are determined based on the type.

Water and Waste Reduction Management
- TBB formulates budgets each year and prioritizes the purchase of products that meet energy conservation marks or similar levels of efficiency for water and electricity use and other equipment. We shall replace old air-conditioning and water usage equipment with new ones that have higher efficiency. TBB requires all units to record the quantity and cost of electricity and water used in each period, and compare them with the same period of the previous year to immediately respond to anomalies. In the renovation of TBB’s premises, we adopt water-saving products such as water dispenser, water-saving toilets and water-saving gaskets installed on faucets, and in conducting the faucet renewal project of the head office, automatic sensor faucets were adopted instead. After the equipment is improved, the water consumption is reduced by 50%, and the per capita water consumption is reduced from 23.39 (cubic meter/person-year) to 21.92 (cubic meter/person-year). Dedicated personnel and maintenance manufacturers would regularly inspect or maintain water equipment, so as to reduce the cleaning frequency of official vehicles.
