Mow Down Pollution was a program designed to retire and recycle old two-stroke engines and to encourage the uptake of cleaner, more efficient alternatives. With the assistance of Automotive Recyclers of Canada (ARC), Scout Environmental was able to implement the program within Home Depot stores across Canada. Individuals who retired their two-stroke engines received a discount on a cleaner, more fuel-efficient alternative. Within The Home Depot, Scout representatives engaged and educated Canadians on the harmful effects of lawn and garden equipment with old, polluting two-stroke engines. A total of 63,789 units were collected and responsibly recycled and 2,149 metric tonnes of point-of-use GHG and smog-forming emissions were prevented.
