Car CO2e emissions calculator

This calculator has been created by Aviva using publicly available government data from the ONS to estimate the CO2e emissions of your journey. ^{Footnote [1]}

CO2 emissions refer to the release of carbon dioxide (CO2) into the atmosphere. It’s a greenhouse gas that is released into the Earth’s atmosphere. CO2e (carbon dioxide equivalent) includes all greenhouse gases.

The mileage you’ve driven is multiplied by a factor based on the fuel type and engine size of your vehicle.

For battery electric vehicles and hybrids, the factors account for any emissions from the electricity to charge the battery.

Our electric car insurance is the same as our standard car insurance, but has a few little extras. We not only have cover for your car, but also its charging cables and wallbox chargers installed in your garage. And your car will be protected if your car is damaged by electrical surge while charging. Subject to our terms and conditions.
