(Note)
- Values for before FY2015 were genereated by TEPCO. Values after FY2016 were generated by TEPCO Energy Partner.
- Base CO2 emissions calculated in accordance with the “System for Greenhouse Gas Emission Calculation, Reporting and Publication” stipulated in the “Act on Promotion of Global Warming Countermeasures”.
- “Base CO2 emissions” and “base CO2 emission coefficient” do not reflect adjustments made based on the feed-in tariff system for renewable energy and carbon credit system.
*In the feed-in tariff system, in principle, all demand households bear surcharges in accordance with their power consumption, so the environmental value is distributed fairly amongst all demand households. In accordance with relavant government regulations TEPCO has reflected this principle in the values for CO2 emission coefficient and CO2 emissions.
*As following, the figures for FY2019 was corrected on November 30,2020.
(After confirmation by the Ministry of Economy, Trade and Industry (METI) and the Ministry of the Environment (MOE), the government will release it as Final Figures.)
・Base CO2 emission coefficient 0.458→0.457（kg-CO2/kWh）
・CO2 emissions intensity (after adjustment) 0.442→0.441k（kg-CO2/kWh）*As following, the figures for FY2020 was corrected on December 27,2021.
(After confirmation by the Ministry of Economy, Trade and Industry (METI) and the Ministry of the Environment (MOE), the government will release it as Final Figures.)
・Base CO2 emissions 85.0→86.3 (million ton-CO2)
・CO2 emissions (after adjustment) 83.6→85.1 (million ton-CO2)
・Base CO2 emission coefficient 0.441→0.447（kg-CO2/kWh）
・CO2 emissions intensity (after adjustment) 0.434→0.441（kg-CO2/kWh）*Previously, there were two types of CO2 emission coefficients: "base" and "after adjustment." However, following discussions at the Coefficient Review Committee in 2024, these have been newly established and reorganized into three types: "unadjusted," "base," and "after adjustment."
FY2024 figures: Base CO2 emissions (unadjusted) 89.8 (million ton-CO2)
Base CO2 emissions (base) 78.0 (million ton-CO2)
Base CO2 emission Coefficient (unadjusted) 0.485 (kg-CO2/kWh)
Base CO2 emission Coefficient (base) 0.421 (kg-CO2/kWh)
