UK Transport Emission Factors
Average kilograms of CO2 equivalent (CO2e) emitted per passenger mile. Switching to lower-emission modes is one of the most effective ways to reduce your personal carbon footprint.
| Transport Mode | CO2e per Mile (kg) | Annual Impact (10-mile commute) | Environmental Rating |
|---|---|---|---|
| Bicycle / Walking | 0.00 kg | 0 kg | 🟢 Excellent |
| Train / Tram | 0.04 kg | ~96 kg | 🟢 Excellent |
| Electric Car | 0.05 kg | ~120 kg | 🟢 Good |
| Bus / Coach | 0.09 kg | ~216 kg | 🟡 Moderate |
| Motorcycle | 0.11 kg | ~264 kg | 🟡 Moderate |
| Diesel Car (Solo) | 0.15 kg | ~360 kg | 🟠 High |
| Petrol Car (Solo) | 0.17 kg | ~408 kg | 🔴 Very High |
Commute Footprint FAQ
Everything you need to know about calculating, understanding, and reducing your daily travel emissions.
Your commute carbon footprint is calculated by multiplying your round-trip daily distance by the number of days you commute per year, and then multiplying that total distance by the emission factor (kg of CO2e per mile) of your chosen transport mode.
Walking and cycling have a near-zero operational carbon footprint. For motorised transport, trains and trams generally have the lowest emissions per passenger mile, followed by electric vehicles, buses, and finally petrol or diesel cars.
On average, a mature tree absorbs about 20 kg of CO2 per year. By dividing your total annual commute emissions (in kg) by 20, you can estimate the approximate number of trees needed to naturally offset your travel footprint.
Yes. While manufacturing an EV has an initial carbon cost, the day-to-day commute footprint is significantly lower. In the UK, an average electric car emits around 0.05 kg of CO2e per mile, compared to 0.17 kg for a petrol car, thanks to the increasingly renewable national electricity grid.
