For many people, the journey to and from work are the bookends of the daily grind. But how we choose to travel to the office, or even to pop to the shops, is also one of the biggest day-to-day climate decisions we face.

In countries like the UK and the US, the transport sector is now responsible for emitting more greenhouse gases than any other, including electricity production and agriculture. Globally, transport accounts for around a quarter of CO2 emissions.

And much of the world’s transport networks still remain focused around the car. Road vehicles – cars, trucks, buses and motorbikes – account for nearly three quarters of the greenhouse gas emissions that come from transport.

So, the way you get around each day can make a big difference to your own carbon footprint.

If you use a car frequently, the first step to cutting down your emissions may well be to simply fully consider the alternatives available to you.

The average petrol car on the road in the UK produces the equivalent of 180g of CO2 every kilometre, while a diesel car produces 173g of CO2/km. In the US the average passenger vehicle on the road releases 650g of CO2/km. Generally, the larger the car, the higher the emissions.
