EV CO₂ Savings Calculator

Estimate how much CO₂ you avoid by driving an EV instead of a petrol or diesel car.

How the CO₂ savings are calculated

The petrol or diesel car’s emissions come from the fuel it burns (about 2.31 kg CO₂ per litre of petrol, 2.68 for diesel). The EV’s emissions come from generating the electricity it uses, which depends on your local grid. The saving is the difference.

This covers driving only. It excludes emissions from manufacturing the vehicle and its battery.
