Mowing Down Pollution: Turn in That Old and Busted Gas Guzzling Lawnmower

Mow Down Pollution is the Clean Air Foundation's annual campaign that encourages Canadians to turn in their old and busted lawn mowers. Over the past seven years, they've retired 18,000 gas lawnmowers and trimmers, resulting in the reduction of 406 tonnes of greenhouse gas and smog-forming emissions.
