We conduct direct and indirect greenhouse gas inventories in compliance with the ISO 14064-1 standards, and file our inventories with the competent authorities in accordance with regulatory requirements. In addition, we gradually set renewable energy targets in line with government policies while reducing greenhouse gas emissions through various greenhouse gas reduction programs and the deployment of renewable energy.
TSC has established a greenhouse gas inventory mechanism in accordance with ISO 14064-1 standards. TSC also includes the progress of these inventories in the matters to be regularly reported to the Board of Directors in line with the Sustainable Development Action Plan for TWSE- and TPExlisted
Companies. We are expected to complete our overall greenhouse gas inventory, which will cover our production sites across Taiwan and China, as well as other overseas operating sites, by 2026. In addition, we continue to expand the scope of inventory categories to identify major carbon emission hotspots within the organization, thereby enabling the formulation of more precise GHG reduction targets. In 2024, TSC’s Scope 1 and Scope 2 greenhouse gas emissions declined, primarily due to greater adoption of renewable energy, which accounted for 23% of the company’s total energy consumption.
Carbon emissions at TSC are dominated by Scope 2 emissions from purchased electricity. As emissions are mainly concentrated in production sites, inventory initiatives have been launched at the site level, with full inventory completion expected by 2026.
According to its Carbon Management Roadmap, TSC’s short-term objective is to establish a solid organizational foundation. This includes completing a comprehensive GHG inventory and initiating product carbon footprint calculations based on the ISO 14067 framework. At the same time, guided by its short-, medium-, and long-term carbon reduction strategies, TSC has strengthened energy-saving efforts across its facilities and begun utilizing renewable electricity. Key initiatives include: rolling out and implementing energy conservation programs, developing renewable energy, stepping up the establishment of management systems, and introducing digital management systems. With a number of energy conservation and carbon reduction measures in place, we endeavor to not only gradually replace old equipment at our production sites with high-efficiency treatment equipment and optimize energy efficiency on an ongoing basis, but also roll out and engage in energy transition by installing renewable energy equipment such as solar power generation facilities across all operating sites, thereby progressively advancing its energy transition efforts.
For direct emissions, TSC plans to progressively implement source management and equipment upgrade strategies to control emission intensity and mitigate direct carbon emissions from operational activities. In 2024, TSC recorded a year-on-year decline in both Category 1 and 2 GHG emissions, largely driven by the increased use of renewable energy. Category 2 emissions were reduced by 7,718.04 metric tons of CO2e, representing a 18% decrease. All emission reductions were in the form of carbon dioxide.
