In 2023, Wafer Works' total greenhouse gas emissions (Scope 1 and Scope 2) amounted to 64,403.3147 metric 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.
Wafer Works is driving energy-saving and carbon reduction initiatives, aiming for sustainable and green production operations. In addition to the increase in Scope 3 emissions, the downturn in the semiconductor industry in 2023 led to a decline in revenue, contributing to an increase in emission intensity due to electricity use to maintain uninterrupted production.
