Department for Transport 'act on CO2' by Leo Burnett

This campaign aims to encourage the public to think about their engine CO2 emissions when driving. The TV campaign introduces the engine as a clever invention, but with unwanted side effects such as CO2 emissions. It goes on to demonstrate simple constructive tips to help your engine emit less CO2. The spot shows a world we all know and roads we may have driven down, tweaked to show just the engine and not the car, to make a lasting impact on audiences.
