According to the Government of Canada (One-Tonne Challenge) a gasoline powered lawn mower emits about 48 kilograms (106 lbs) of greenhouse gas in one season. Gas-powered lawn mowers are very inefficient, which means that despite their small size they produce a lot of air pollution. In fact, running an older gasoline-powered lawn mower for one hour can produce as much air pollution as driving a new car 550 kilometers. Source: Ministry of the Environment-Canada. A conventional lawn mower pollutes as much in an hour as 40 late model cars for an hour. Source: EPA statistics for Replacing Gas Power Lawn Mowers Assuming that a typical car travels 18,000 km per year, 33 gasoline lawn mowers would produce as much pollution a car produces all year. The 56 million gasoline-powered lawn mowers generate as much pollution as 1.7 million cars. Traditional landscaping gasoline engines create Ozone, O3, a colourless, odourless gas at ambient concentrations which is a major component of smog.
