Carbon calculator: Compare CO2 emissions by mode
for your journey

Welcome to the CO2 emissions calculator.  Most of us know already that it's more environmentally friendly to travel by public transport, but here you can find out the CO2 emissions of your own journey.

You will also see how your chosen mode of transport compares against others. The CO2 emissions calculator compares travel by car, bus, train and motorbike.
