Ghg Emission Factors: waste
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). Sources: EPA GHG Emission Factors Hub 2024, EPA eGRID2022, IPCC AR5 WG1 Annex II, 40 CFR Part 98, GHG Protocol Corporate Standard, EPA WARM v15.
| emission source type | record id | ch4 g per unit (g CH4/unit) | co2 kg per unit (kg CO2/unit) | co2e kg per unit (kg CO2e/unit) | fuel or source | gwp basis | n2o g per unit (g N2O/unit) | notes | unit notes | unit of activity |
|---|---|---|---|---|---|---|---|---|---|---|
| waste | composting_ton | 0 | 0 | 9 | composting of organic waste | AR5 | 0 | CO2 from composting is biogenic and excluded; CH4 and N2O emissions during decomposition included; open windrow composting | kg CO2e per short ton of organics composted | short ton organics |
| waste | landfill_msw_ton | 0 | 0 | 315 | municipal solid waste landfill | AR5 GWP100 CH4=28 | 0 | Includes CH4 from decomposition; based on 50% landfill gas collection efficiency; biogenic CO2 excluded; varies with waste composition and collection efficiency | kg CO2e per short ton MSW landfilled (methane emissions over 100yr) | short ton MSW |
| waste | recycling_mixed_ton | 0 | 0 | -1,000 | mixed recycling (avoided emissions credit) | AR5 | 0 | Emission credit relative to virgin material production; value is weighted average across paper/glass/metals/plastic mix; negative value = emissions savings | kg CO2e avoided per short ton of mixed recyclables processed (negative = credit) | short ton recycled |
