The monitoring conducted by the children showed that, on the backstreets, pollution can be up 50% lower than on the main roads. So they have now discovered for themselves that choosing back roads to get to school is a very simple way to reduce the amount of polluted air they breathe.

Illustrations of a ‘smog man’ character and ‘superwalker kids’ have been created by the talented children’s book illustrator, Al Murphy, for this project and are used on banners of the maps that have been put up at schools, to remind families every day how to ‘beat the smog’.
