Mowdown Pollution is a great iniative of the Clean Air Foundation http://www.cleanairfoundation.org/ and The Home Depot of Canada http://www.homedepot.ca/ that encourages Canadians to retire their older, higher polluting gasoline mower or trimmer.
We developed an online training module including live action and screencast videos to help train the reps who ran the program in 166 Home Depot stores coast to coast.
