Emissions (CO2e) calculator.

Estimate annual electricity and diesel combustion emissions. Edit the factors to match your site, then inspect every pound-to-tonne conversion.

Annual facility inputs

The 2,000,000 kWh electricity value is an illustrative starting sample. Replace it with your annual meter total. The grid factor and diesel defaults follow the requested starting values.

kWh / year

Enter the annual electricity used by the facility.

lb / kWh

Default 0.82 from EPA eGRID's 2022 U.S. average; editable. Use your local eGRID subregion factor for reporting.

gal / year

Default 0 gallons; diesel combustion uses 22.5 lb CO2 per gallon.

Assumptions & limits

Check the boundary before reporting.

CO2 only (CH4/N2O excluded, typically ~1%); grid factor varies widely by region—enter the local eGRID subregion value for reporting use.

Electricity and diesel are combined as annual operational CO2. The diesel factor covers combustion only; upstream fuel production and delivery are outside this estimate. EPA publishes regional eGRID rates and its diesel fuel value as 22.44 lb CO2 per gallon, rounded here to the requested 22.5 lb/gal input factor.
