Between 2022 and 2025, TSC implemented improvements targeting the company's main sources of high carbon emissions, upgrading the oil-fired boilers at the Dalin Biotech Plan and Xiaogang Plant to natural gas. Meanwhile, the orchid greenhouse oil-fired boiler was gradually converted to heat pump heating, reducing fossil fuel emissions through the electrification of process equipment.

Taiwan Sugar Corporation is committed to environmental sustainability and actively promotes its net-zero emissions plan. Starting in mid-March 2022, the Xiaogang Plant boiler was converted to use natural gas instead of low-sulfur fuel oil. According to statistics, GHG emissions in 2025 totaled 58,631.8966 metric tons of CO₂e, a reduction of 4,777.6267 metric tons of CO₂e compared to 2024. TSC will continue to improve its processes and optimize its equipment to contribute to achieving Taiwan's Pathway to Net-Zero Emissions in 2050.

Based on the operational performance statistics for 2025, overall GHG emissions decreased by 7.53%. Significant results were also achieved in the control of air pollutants. The concentration of sulfur oxide emissions reduced to 0 ppm and that of nitrogen oxide emissions reduced by more than 15%, and the emissions have been reduced by more than 25% compared to the previous year, demonstrating excellent environmental benefits.
