Formula
The Car Carbon Footprint Calculator uses the formula:
Annual CO₂ emissions = Annual distance ÷ Fuel efficiency × CO₂ per litre
Worked example
For example, with annual distance of 15,000 km, fuel efficiency of 15 km/l and co₂ per litre of 2.31 kg/l, the annual co₂ emissions is 2,310.
| Annual distance | 15,000 km |
|---|---|
| Fuel efficiency | 15 km/l |
| CO₂ per litre | 2.31 kg/l |
| Annual CO₂ emissions | 2,310 |
|---|---|
| Trees to offset (per year) | 110 |

Frequently asked questions
Find the litres used (distance ÷ efficiency), then multiply by CO₂ per litre. 15,000 km at 15 km/l with petrol emits about 2,310 kg of CO₂ a year.
Burning a litre of petrol releases about 2.31 kg of CO₂; diesel is higher at around 2.68 kg per litre.
A mature tree absorbs roughly 21 kg of CO₂ a year, so the calculator divides emissions by 21 for an estimate.
Drive less, drive efficiently, maintain the car, carpool, or switch to a more efficient or electric vehicle.
