Sustainability

All TSC production sites have put in place a greenhouse gas inventory mechanism in accordance with the ISO 14064-1 standards. TSC also includes the progress of these inventories in the matters to be regularly reported to the Boar of Directors in line with the Sustainable Development Action Plan for TWSEand TPEx-listed 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 emissions categories in accordance with the latest ISO 14064-1:2018 standards, in hopes of understanding the emissions hotspots of the organization through our inventory and setting more accurate greenhouse gas reduction targets. In 2023, there was a slight increase in TSC’s overall greenhouse gas emissions due chiefly to the expanded scope of inventory at our Li-Je and Shandong sites, as well as emissions of perfluorocarbons (PFCs), sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3) as a consequence of the newly developed manufacturing processes at our Li-Je site. 

Carbon emissions at TSC are dominated by Category 2 emissions from purchased electricity. Since carbon emissions primarily emanate from all our production sites, greenhouse gas emission inventory was first rolled out at each production site, while our overall greenhouse gas inventory is scheduled for completion by 2026
