Remark:
(1) The corporate GHG emissions boundary includes the headquarters, Energy business and Engineering and Turnkey business.
(2) The 2024 GHG emissions data have been updated due to the revision of emission factors (EF) based on the latest national database. Consequently, the base year data has been recalculated to ensure accuracy, maintain currency with regulatory guidelines, and enable consistent year-on-year comparability.
(3) Other indirect GHG emissions (scope 3) cover only those categories identified through a significant indirect GHG emission assessment and verified by an external party. These figures represent the total emissions from significant categories across the headquarters, Energy business, Engineering and Turnkey business, and High-voltage Equipment business.
(4) Total other indirect GHG emissions (scope 3) by relevant activity categories represent the sum of indirect emission sources from the headquarters, Energy business, Engineering and Turnkey business, and High-voltage Equipment business.
