Carbon tracker

Compare estimated operating emissions.

Adjust the assumptions to compare a petrol vehicle with an electric vehicle over one year.

Compare operating emissions.

Use your own distance, energy use and emissions factors to compare two operating scenarios.

Petrol estimate1,410 kgCO₂ per year

Electric estimate338 kgCO₂ per year

Calculation

Petrol: distance ÷ 100 × litres per 100 km × kg CO₂ per litre.

Electric: distance ÷ 100 × kWh per 100 km × kg CO₂ per kWh.

This comparison covers direct petrol combustion and electricity generation represented by your grid factor. It excludes vehicle and battery manufacturing, maintenance, disposal and upstream petrol emissions.
