Which one do you need?
- Household Carbon Footprint Calculator
- Total your household's annual CO2e from electricity, gas, propane, oil, driving and flights using published emission factors, and see the figure per person.
- Driving CO2 Emissions Calculator
- Calculate CO2 and CO2e from driving using EPA tailpipe factors for gasoline and diesel, with grams per mile, grams per km, annual tonnes and an EV comparison.
- Flight Carbon Footprint Calculator
- Estimate per-passenger CO2e for any flight from great-circle distance, haul-length emission factor, cabin class multiplier and a radiative forcing uplift.
- Electricity CO2 Emissions Calculator (kWh to CO2)
- Convert electricity use into CO2e with a regional grid factor, gross up for transmission losses, and compare location-based and market-based results.
