2005 Toxicity-Weighted Emissionsby Pollutant

Residential Wood Combustion

U.S. Metropolitan Housing Survey (2005)

53,000+ uncertified woodstoves

18,000+ certified woodstoves

Almost 2,000 OWBs

American Lung Association of Maine (Nov 2008, N=3,204)

38% planned to burn wood

16% use wood as principal heating fuel

¼ of woodstoves > 20 years old

Market Decisions (Nov 2009, N=400) 43% of Mainers burn wood for heat

67% of Mainers do not perceive woodsmoke as an air pollution problem
