emit 19.6 kg of PM2.5, as much as 196 diesels and 1 0 0 0 petrol cars!
The NSW Air Emissions Community Web tool (image, below) shows that residential wood heating
is responsible for more PM2.S emissions in Sydney that all other sources combined

Proportion of PM2.5 emissions (the most health-hazardous air pollutant) emitted by residential wood heaters (purple line
joining the triangles) in Sydney by month. This g raph from NSW EPA website, is from their emissions inventory which
shows that more than half of all man-made PM2.5 emissions are from the small proportion of households using wood
heaters. ABS statistics showthat only 5Vti of Sydney households use wood as the main form of heating.

A B C News April 2008: Wood smoke worse that car exhausts
"In t h e limited a m o u n t o f studies that have been done so rar that h a v e directly comp ared
s m o k e from fires w i t h t h e s a m e l e v e l o f pa r t i c u l a t e s a n d s m o k e f r o m c a r e x h a u s t ,
industry have a l l tended to s h o w that the effects f r o m the w o o d s m o k e are actually worse
f o r l u n g conditions t h a n a s i m i l a r a m o u n t f r o m , say, car exhausts"
Norwegian Study comparing genetic damage from woodsmoke and traffic in human
cell lines: "In conclusion, woodsmoke p articulate matter (WSPM) generated more DNA damage than trafficgenerated PMp er unit mass in human cell lines, possibly due to the high level of polycyclic aromatic hydrocarbons in
WSPM. This suggests that exp osure to WSPM might be more hazardous than PM collected from vehicle exhaust with
respect to development of lung cancer."
Greenhouse gases.
Methane emissions from the average woodheater can cause more global warming than heating the same house with gas
or reverse cycle airconditioning.

and five other states sued the U S E P A because their "25 years of inaction on woodstove emission
standards violates the C l e a n Air Act". However, progress h a s b e e n slow. T h e n e w standards reduce

correctly-operated stove burning seasoned w o o d . Real-life emissions are often m u c h higher.
