Ground-level Ozone and Your Yard

Did you know that operating a typical gasoline-powered lawn mower for one hour produces the same amount of ground-level ozone forming pollution as driving an average car almost 200 miles?

There are many ways that you can help reduce ground-level ozone everyday.  Here are some tips for reducing air pollution while maintaining your lawn and garden.

  1. Consider using less polluting gas-powered equipment.
    • Consider purchasing electric equipment such as lawn mowers, weed eaters, and leaf blowers/vacuums.
    • California has regulations requiring lower-emitting gas-powered lawn equipment in their state.  This equipment is also sold outside of California.  Contact you local equipment dealer and ask about the availability of this equipment.
  2. Use manual tools when possible.
    • Consider purchasing manual equipment such as push reel mowers, rakes and hedge clippers.
  3. If you need to use gas-powered equipment, purchase equipment with a four-cycle engine instead of one with a two-cycle engine.
    • Four-cycle engines emit less air pollution than two-cycle engines.
  4. Properly maintain your equipment.
    • Follow the manufacturers guidelines for maintenance.
    • Keep the underside of the mower deck clean.
    • Maintain sharp mower blades.
    • Periodically tune-up your equipment.
    • Change the oil and clean or replace filters regularly.
  5. Reduce your mowing time.
    • Use low maintenance turf grasses that grow slowly and require less mowing.
    • Decrease your lawn area (mowing area) by planting more trees, shrubs and flowers.
