Effects of wood stove interventions on outdoor particulate matter (PM) levels in developed countries
| Location | Estimated reduction in PM µg·m−3 | Notes | References |
| Launceston, Tasmania, Australia | 38% reduction in winter PM10 | Fuel switching: replacement of wood heating appliances with electric heating appliances. The proportion of households burning wood was reduced from 66% to 30%. | [72] |
| British Colombia, Canada | 22% reduction in winter PM2.5 | Introduction of improved technology stoves and targeting of open fireplaces. The proportion of homes using open fireplaces was reduced from 15% to 3%, and the proportion of homes with improved technology wood stoves increased from 25% to 41%. The community also had an overall increase in wood stove usage. | [73] |
| Missoula, MT, USA | 45% reduction in PM10 | Legislative action and enforcement. Over a 10-year period, the proportion of households burning wood was reduced from 44% to 20% and the contribution of residential wood burning to PM10 was reduced from 47% to 11%. | [74] |
| Libby, MT, USA | 27% reduction in winter PM2.5 | Introduction of improved technology stoves. Over 1100 older model wood stoves were replaced with improved technology stoves. | [75, 76] |
PM10: particles with a 50% cut-off aerodynamic diameter of <10 µm; PM2.5: particles with a 50% cut-off aerodynamic diameter of <2.5 µm.
