According to the EU, driving accounts for around 12% of CO₂ emissions. Cutting down on car journeys can help slow climate change – but when you do need to drive you can do it in a more eco-friendly and green way.  This is called hypermiling and is a way to squeeze the maximum mpg (miles per gallon) out of a tank of petrol. We’ve tried it, and it is possible to radically increase the mpg of your car, saving a small fortune in petrol and emissions in the process.
