Cars are destroying the world’s forests. A quarter of the forests lost in the last 10,000 years have been destroyed in the last 30 years. To help turn the tide, Greenpeace is launching a campaign for the Car Free Day 2009.

To drive the point home to drivers and make them understand the direct link between their behaviour and the destruction of trees, a saw was created out of a car key and is shown in the ad being used to cut down a tree. The implication of course is that every time the driver starts his engine he is helping to cut down a tree. The message on the key says, "You are driving our forest to destruction." Having made the point, the ad then offers a solution by inviting drivers “Show your support for Car Free Day 2009 at climatehero.greenpeace.org.cn”.

Over 50,000 people visited the car free day web site within a week of the ad launching. More than 30,000 drivers have registered to join the event.
