Department for Transport 'revs' by Leo Burnett

Each poster features a computer-generated image of an engine with wheels and an exhaust. The exhaust pipe emits a cloud, in which there is information on how to reduce the CO2 emissions of your car. As well as informing drivers that: "Less revs means less CO2" and "pumped-up tyres mean less CO2", the posters also drive people to a website where they can get more tips on tackling climate change.
