Yard Maintenance

Yard maintenance is often overlooked as a source of air pollution. However, emissions from lawnmowers, snowblowers, chainsaws, weed-eaters and leaf blowers/vacuums are significant: small engines are big polluters.

Here are some tips that will help reduce the emissions your yard activities generate:

  • Avoid using outdoor power equipment on hot summer days when smog is already a problem.
  • Use small gas-powered machines (mowers, chainsaws etc.) less often or for shorter periods of time.
  • Follow the manufacturers recommended gasoline to oil mix for two-stroke engines.
  • If you have a choice, four-stroke engines are less polluting than two-stroke.
  • If you are replacing gas powered equipment consider manual options, electric, or low-emissions alternatives.
  • Mowing after 7p.m. allows ozone-forming chemicals to dissipate overnight.
  • Avoid idling, it is hard on air-cooled engines and wastes gasoline.
  • Perform regular maintenance to make sure your equipment is running at optimum efficiency.
  • Use snow blowers for moderate or heavy snowfalls, for light snow consider manual alternatives.

Did you know?

  • Depending on the year, make and model, lawnmowers emit as much pollution in one hour as driving a car from 20 to 200 miles.
  • Electric mowers reduce pollution by 90%.
  • Four-stroke engines are 70% more efficient than two-stroke engines.
