Enter your Vehicle Type, Powertrain, Fuel Efficiency, and Annual Miles into the Well-to-Wheel Emissions Calculator to find your Total CO2e — broken down into Well-to-Tank and Tank-to-Wheel emissions, plus Emission Intensity per mile.

Well-to-wheel (WTW) includes all lifecycle emissions. Well-to-tank (WTT) covers upstream fuel production, refining, and delivery. Tank-to-wheel (TTW) covers direct emissions from vehicle operation.
The calculator uses your ZIP code to determine your regional electricity grid mix and applies the corresponding CO2e emissions factor per kWh based on EPA eGRID data.
Electric vehicles have upstream emissions from electricity generation at power plants. The amount depends on your local grid's energy mix - renewable grids produce lower WTT emissions.
The calculator uses EPA and ISO 14083:2023 methodology with industry-standard emissions factors. Results are estimates that may vary based on actual driving conditions and fuel sources.
Hydrogen vehicles have zero direct emissions, but their total impact depends on hydrogen production method. Green hydrogen from renewable electrolysis has the lowest lifecycle emissions.
Hybrids typically reduce both WTT and TTW emissions through improved fuel efficiency. Plug-in hybrids can achieve even lower emissions when charged with clean electricity.
