Taipower's Electricity Carbon Emission Factor Drops to 0.467 kg CO₂e/kWh; MOEA Reports Progress in Energy Transition

The Energy Administration under the Ministry of Economic Affairs (MOEA) announced on June 2 that the 2025 electricity carbon emission factor for public electricity retailers has decreased to 0.467 kg CO₂e/kWh, representing a 1.5% reduction from 2024 and an overall decline of approximately 12% compared with 2016. According to the MOEA, the continued decline reflects tangible progress in Taiwan's energy transition efforts, including the expansion of low-carbon power supply and the optimization of the thermal power generation mix.

To better support corporate carbon accounting and international disclosure requirements, the MOEA has introduced separate electricity emission factors beginning in 2025. The Industrial Electricity Emission Factor is set at 0.466 kg CO₂e/kWh, providing businesses with a standardized reference for emissions inventory and reporting, while the Residential Electricity Emission Factor for non-commercial household users is 0.471 kg CO₂e/kWh. The ministry noted that growing demand for renewable electricity from global supply chains has led industries to procure increasing amounts of green power through various channels.

The MOEA further explained that the public electricity retailer emission factor reflects emissions associated with electricity sold through the Taipower system, whereas the National Electricity Emission Factor additionally incorporates renewable energy supplied through direct and wheeled transactions in the private market. The preliminary estimate for 2025 is 0.456 kg CO₂e/kWh, approximately 14% lower than in 2016. The ministry emphasized that, amid rising electricity demand from semiconductor manufacturing, AI applications, and data centers, Taiwan must continue expanding renewable energy while deploying low-carbon natural gas generation to maintain grid stability, strengthen system resilience, and support the nation’s net-zero transition goals.
