PREVENTING OZONE

In Your Yard

Lawn mowers and lawn equipment contribute to nearly 10% of the Denver area’s ozone pre-cursor emissions.  You can do your part to reduce emissions from your yard by following these simple tips:

  • Delay mowing until evening — don’t mow, let it grow.
  • Maintain your gas-powered mower to help it run cleaner — change the air filter, oil and spark plugs at least once each season. Keep the underside of the mower free of grass build-up.
  • Avoid using two-stroke gasoline-powered yard equipment, such as weed trimmers, since they emit a disproportionate share of air pollution.
  • Use a funnel to refuel equipment — avoid even small spills and drips.
  • Reduce lawn watering and fertilizing to discourage excessive lawn growth.
  • Xeriscape to reduce lawn area, or change to native western grasses to reduce the need for irrigation and mowing.
  • Choose an alternative to charcoal grilling.
  • Don’t use petroleum distillate charcoal lighter fluids, which emit a lot of harmful vapors. Use an electric starter or charcoal chimney instead.
