Most of us don’t think of lawn mowers as causing much air pollution, but running a two-stroke gas-powered mower for one hour can puff out as much pollution as driving a new car for 550 kilometres, according to Ontario’s environment ministry. Multiply that by the 2.7 million Canadians mowing their lawns every weekend in the summer, and lawn mowers become a significant source of green house gasses, air pollution and smog.
What can you do about it?
- The most environmentally friendly alternative to a gas mower is the reel push mower, which provides you with a bit of exercise and emits no pollution.
- A number of manufacturers are producing electric or cordless rechargeable mowers. They are easy to start, require no gas or oil and are very cheap to run. Also, some of these mowers generate about half the noise levels of their gas-powered counterparts.
- Four-stroke mowers are 70% more efficient and choke out less smog-inducing fumes than two strokes. A four-stroke gas mower with a spill-proof can, also prevents gasoline spills thereby lessening the environmental impact of using gas-powered mowers.
