Summary:
The aim of the study is to assess the effect of the subsidy to replace old wood stoves for new clean burning stoves, and to what extent the scheme has influenced the total particle emissions and pollution concentrations in Oslo municipality. NILU selected three methods; 1) emission and dispersion modelling for 4 different scenarios; 2) estimate the emission reduction associated with the subsidy scheme in Oslo municipality; and 3) a comparison of changes in emissions, wood consumption and emission factors over time in municipalities with and without subsidy. Modeling and assessment of the potential emission reduction associated with the subsidy scheme shows that it has a potentially significant effect on the reduction of particulate emissions and concentrations of PM2.5 and PM10. The estimates show that the subsidy scheme in Oslo municipality gives a significant reduction in average emission factor over time. However, the effect on total PM-emissions is small.
