On 2 June 2026, the Ministry of Economic Affairs’ Energy Administration announced the FY2025 (ROC year 114) public electricity retailer emission factor of 0.467 kg CO₂e/kWh, approximately 1.5% below FY2024 (ROC year 113) and 12% below FY2016 (ROC year 105). For the first time, separate industrial (0.466) and residential (0.471) factors were introduced, alongside a preliminary national electricity emission factor of 0.456 that includes private green electricity trading. For companies preparing GHG inventories, reporting Scope 2 emissions or responding to international supply chain decarbonisation requirements, these annually updated figures underpin electricity emissions calculations. This article explains the four factors, five-year trends and how companies should correctly apply officially announced factors.
