About this factor
Description by open-climate.ai
Domestic steam coal: statutory CO2 emission factor for direct fuel combustion under Japan's mandatory GHG accounting and reporting programme, published as 2.15 tCO2 per t in 参考1 of ichiran_2025r.pdf. The publisher derives it from its own appended tables as 24.2 GJ/t (別表1, gross heating value) x 0.0242 tC/GJ (別表2, carbon emission coefficient) x 44/12. CO2 only: the programme publishes CH4 and N2O combustion factors in a separate table, and biogenic CO2 is not counted. 【根拠条文】算定省令第2条第4項及び別表第1.
