Distance [km] ÷ 100 × Consumption [l/100 km] × Emission factor [kg CO₂/l]

Understand the inputs

Distance
Unit: km. Use a measured value or your own assumption.
Consumption
Unit: l/100 km. Use a measured value or your own assumption.
Emission factor
Unit: kg CO₂/l. Use a measured value or your own assumption.

Assumptions and limitations

The factor describes direct emissions per litre of fuel. Fuel production, electricity mix, vehicle manufacturing and other lifecycle emissions are not automatically included.

The formula uses the specified units. Displayed numbers are rounded; whole packs, item counts and full time periods may also be rounded within the calculation.
