In 2025, Taiwan Sugar Corporation's electricity consumption was still mainly purchased electricity (Taipower), accounting for 68.93% of the total electricity demand. The annual GHG emissions (Category 1 + Category 2) reached 136,036.7940 metric tonnes of CO₂e. The main carbon emitters are the Livestock and Sugar Business Divisions, which together accounted for approximately 81.57% of the company's total emissions. They have been listed as priority improvement targets for carbon reduction and energy conservation.

In 2025, the internal energy consumption of Taiwan Sugar Corporation was 3,170,549.54 GJ, and the total energy consumption intensity was 0.1002 GJ/NTD thousand of revenue. The main reason for the discrepancy is to improve data quality and information transparency. More precise parameter corrections have been applied to the calorific value conversion of biomass energy (bagasse) to more accurately reflect current energy usage, which has resulted in differences from the baseline figures reported in previous years. 

TSC has been dedicated to carbon reduction for years, the GHG emissions were converted from the material input into the environmental accounting system, and are disclosed in this Report. Starting from 2022, TSC has followed the ISO 14064-1 greenhouse gas inventory principles to conduct a company-wide greenhouse gas inventory for the year 2021. Provide the disclosure of more accurate emission figures, and the implementation will be conducted annually thereafter. From 2025, the Company has been incorporated into the Public Sector Chief Sustainability Officer Alliance and will revise the GHG inventory approach to align with the Ministry of Environment’s regulations for voluntary GHG inventories. In 2025, the total GHG emissions was 136,036.7940 tCO2e, a decrease of 2.20% compared with 2024. The GHG emission intensity is 0.0043 tCO2e/NTD 1,000 of revenue, a decrease of 2.27% compared with 2024. The main reason is that the pig farms decreased the number of pigs due to the renovation, resulting in a reduction in the Company’s overall GHG emissions.

In terms of the verification of GHG inventory, in addition to the originally planned Xiaogang Plant of the Sugar Business Division, in 2024, the Jianshanpi Resort of the Leisure Business Division also conducted a 2024 GHG guidance inventory in accordance with the Ministry of Environment's "Greenhouse Gas Emissions Inventory Operation Guidelines (2024 Edition)", and obtained a greenhouse gas verification statement through verification by a third-party impartial unit. Verification of 2024 emissions conducted in 2025 was carried out only at the Xiaogang Plant in accordance with the Ministry of Environment’s regulations.
