Best foot forward
Research shows that levels of pollutants inside a car are at least three times worse than on the pavement, so driving to school is not just bad for the environment, it's bad for your health.
The morning school run is now one of the most polluting journeys as cars produce more greenhouse gases on short journeys when the engine is cold and there's constant stopping and starting in traffic jams.
Walk to School week is a joint campaign by Travelwise and Living Streets.
And who knows, you might even find that it turns out to be quicker and less stressful than taking the car.
