Ghg Emission Factors: electricity
GHG emission factors for carbon footprint and greenhouse gas inventory calculations — 64 records across 6 source categories. Stationary combustion (natural gas, diesel, propane, coal, fuel oils, biomass) in kg CO2e per mmBtu or per physical unit. Mobile combustion (gasoline, diesel, jet fuel, marine) in kg CO2e per gallon. Electricity by 26 EPA eGRID2022 US subregions + national average in kg CO2e per MWh. Refrigerant GWP (R-134a through SF6) in kg CO2e per kg refrigerant. Process emissions (cement, steel, aluminum, lime). Waste (landfill, composting, recycling credits).
