Emissions from sustainable increases in residential wood combustion in Switzerland

Existing fuel consumption and installation trends in the Swiss small scale residential wood combustion (RWC) fleet were parameterized and projected, giving an indication of potential future fleet characteristics. These usage projections were then applied to an in-house combustion emission inventory and estimates of future PM2.5 emissions were made. Where possible uptake of new technology was accounted for. A cases study involving the costs benefit analysis of retrofitting one of the system classes (Fireplaces) with electrostatic precipitators (ESPs) was conducted. A scenario detailing 100% uptake of the ESPs is shown and identifies significant capital expenditure costs relative to improvements in air quality external costs.
