Quick answer
Multiply the kilometres you travel in a year by an emission factor for your mode of transport. A 15 km each-way commute, five days a week for 48 weeks, is 7,200 km a year; by car at 0.164 kg CO₂e per km that is about 1.2 tonnes, while by metro it is about 0.2 tonnes.
It multiplies your yearly commute distance (one-way distance × 2 × days a week × weeks a year) by a factor for your mode. Sharing a car divides its emissions by the people in it. Electric vehicles use your vehicle's electricity per kilometre multiplied by India's grid factor of 0.710 kg CO₂ per kWh.
| Mode | Factor |
|---|---|
| Car (average) | 0.164 kg CO₂e per km |
| Cab or taxi | 0.208 kg CO₂e per km |
| Small motorbike or scooter | 0.083 kg CO₂e per km |
| Bus | 0.104 kg CO₂e per passenger-km |
| Metro | 0.029 kg CO₂e per passenger-km |
| Train | 0.035 kg CO₂e per passenger-km |
Transport factors are from the UK DESNZ 2025 conversion factors, used as an approximation for India; electricity from the CEA CO₂ Baseline Database v21.

Per kilometre, a small motorbike or scooter emits about half as much as an average car, using the DESNZ factors. Metro is lower still per passenger. Buses vary with how full they are: the average-bus factor we use is a little higher than a small two-wheeler.
By the electricity they use per kilometre multiplied by India's grid factor. Change the kWh per km under Assumptions to match your vehicle.
Yes. The car's emissions are shared, so two people in one car each have half the footprint of driving alone.
There is no complete official Indian set of per-kilometre factors for every mode, so we use the UK government set as an approximation.
Cut what you can first; then plant trees for the rest. Each tree is a 2-3 ft sapling, cared for three years and geo-tagged, from ₹299.
