In 2024, Wafer Works' total greenhouse gas emissions (Scope 1 and Scope 2) amounted to 69,931.21metric tons of carbon dioxide equivalent. The primary emissions came from Scope 2 purchased electricity, followed by process emissions, including perfluoropropane (C3F8) and nitrous oxide (N2O). For the first time in 2022, Scope 3 emissions were included in the inventory, primarily focusing on other indirect emissions generated from outsourced activities, with emissions sources owned or controlled by other companies.
Total Greenhouse Gas Emissions Increased in 2024: Due to the addition of a 12-inch production line at the Longtan Plant, total carbon emissions rose in 2024. In response, the annual energy-saving target was set at 1.5%. The combined energy savings from both plants in 2024 reached a 2.7% reduction compared to the previous year, thereby achieving the carbon reduction target.
