Burning Wood Produces Wood Smoke and Air Pollution

We have a wintertime air pollution problem. During fall and winter, Multnomah County sees a rise in pollution that comes from wood smoke. Check for burn restrictions before burning wood. 

Wood smoke from home heating accounts for more than half of our fine particle pollution on the average winter day. These pollutants are harmful to human health.

Our air must meet federal standards for fine particle pollution under the Clean Air Act. Although we currently meet these standards, we are at risk for violating federal law if we have too many days of unhealthy air.

If we don’t clean up our air, we’ll face several issues:

  • Health impacts - The longer we wait to clean up our air, the longer we’ll all be breathing unhealthy levels of pollution. Health effects of wood smoke»
  • Economic impacts - Federal funding for transportation (highway) projects could be at risk.
  • Business impacts - Restrictions placed on large businesses located in Multnomah County, which may push jobs outside our community.

Ways to Reduce Wood Smoke

Heat Your Home with a Cleaner Fuel

  • Use a cleaner heat source such as an electric heat pump, or a furnace that uses electricity, natural gas, propane or oil.
  • Check local air quality conditions before you burn, every time.
  • Remember, NEVER heat your home using a gas oven, kerosene heater, camping stove or BBQ. Using space heaters as your main heating source is also unsafe.

Replace Equipment

  • Use Energy Trust of Oregon cash incentives to help pay for a new electric or natural gas-burning device.
  • Uncertified wood stoves and inserts create twice as much air pollution as EPA-certified stoves. Switching to a certified device will help reduce the amount of fuel needed to warm your home.
  • A tax credit may be available when you replace a wood or pellet stove that is at least 75 percent efficient. Learn more here

Burn Cleaner

  • Burn only dry, split, well-seasoned wood. Properly seasoned wood is darker, weighs less, and sounds hollow when hit against another piece of wood.
  • Keep wood covered and off the ground. Store it at least 12 months before burning.
  • Build small, hot fires.
  • Never burn trash or construction debris such as treated wood, painted wood or particle board. They make toxic smoke and can damage your stove.

Weatherize Your Home

You can help make your home warmer by adding insulation and sealing drafts around doors and windows.
