I found this interesting, if you were to run your lawn mower for about 1 hour it will produce about the same amount of pollution as a car that has driven 500km.

Using a two-stroke lawn mower to cut a decent-sized lawn can produce as much smog-forming pollution as driving a modern car from Ottawa to Toronto.

If Canada wants to have the average household drop there green house emissions then lets have a look at some flexible numbers.

It took me 1hr to mow my parents law, thats 50′ x 100′ lot, thats more or less the average size of an older lot in Edmonton (before the housing boom) so in that hour the lawn mower potentially released as much pollution as driving a modern car 500km. The grass usually gets cut at least once a week. So in a month thats 2000km most people don’t drive that much in city conditions.

It make sense for Canadians to look into more efficient small engines, i would assume this would account for small boats, dirt bikes, chain saws, and land escaping equipment.

People also seam to want the perfect golf course looking law, cutting the grass so its 1″ long. Believe it or not having your lawn cut that short will cause the lawn to loose moisture and is actually hard on the grass. Remember its a plant, grass grows long, so leave it longer. This will allow it to shade its self keeping i’m moisture and reducing your water bill.
