Carbon Dioxide Emissions Calculation
Calculates carbon dioxide, methane, and nitrous oxide emissions from household energy use.
Carbon dioxide emissions per household are 2,470 kg/year

・The emission factors for each fuel are based on
the Ministry of the Environment’s “List of Calculation Methods and Emission Factors for the Calculation, Reporting, and Disclosure System: 2025 Revised Edition”
CO₂ equivalent global warming potentials: Methane (CH₄) = 28, Nitrous Oxide (N₂O) = 265
“Methods for Calculating Greenhouse Gas Emissions and Absorption: 1.A.3.b Motor Vehicles (CH₄, N₂O)”(Submitted in 2025)
Japan LP Gas Association “Regarding CO2 Emission Factors”
・For calculating CH4 and N2O emissions from gasoline and diesel, the fuel economy is set at 10 km/L; however, please adjust this value to reflect actual conditions.
