The planned large scale introduction of wood combustion based domestic heating systems in Austria (planned for up to 400,000 households) would increase the Austrian PM2.5 emission by around 6% based on an average emission of 30 mg MJ−1, if the old "high emitting" solid fuel based heating systems are not replaced.
