What can you do to help?
Air pollution is the single largest environmental health risk in Europe. Pollutants, such as particulate matter (PM), nitrogen oxide (NO2), sulphur dioxide (SO2), carbon monoxide (CO) and benzo(a)pyrene, can harm human health when high levels of concentration are reached. It is, therefore, crucial to understand the sources of these emissions and tackle them effectively.
With 80,6 % of the final energy consumption in the residential sector being used for heating (space & water heating), it is essential to cover this heat demand with decarbonised and clean energy sources. Whilst wood heating that comes from an existing stock of old and inefficient installations is responsible for some pollutant emissions, modern wood heating installations are quite the contrary. Having closed wood stoves, pellet stoves or boilers are today highly efficient, with near-to-zero emissions being produced.
As a result, our industry is in the driving seat to not only decarbonise our heat demand but also to improve air quality from residential heating, substituting fossil installations and old wood installations with modern biomass heating.
To achieve this objective, four factors play a vital role to decrease emissions from wood heating:
Replace old appliances with modern ones
Improve fuel quality
Feedstock characteristics such as water content have a big impact on combustion efficiency and air emissions. It is estimated that using wood with less than 20 % moisture allows a reduction of emissions by 8 times (compared to wood with 30 % of moisture content) and simultaneously increase efficiency while reducing the amount needed. More broadly, fuel quality standards and certification schemes like ENplus® are essentials to guarantee the lowest levels of air emissions.
Ensure installers are trained, regular maintenance performed
Installers play a pivotal role in the energy transition and switch to domestic renewable energies. They are the ones in contact with end consumers and can increase awareness. In addition, installers and chimney sweepers ensure efficient functioning of biomass stoves via their maintenance and cleaning operations; but also instructing users on how to properly operate and clean the appliances leads to added efficiency. For these reasons, their knowledge on biomass appliances and their recommendations to final users on which appliance is more suited for their needs are key for increased efficiency and lower emissions.
Raise awareness among users
Consumers’ knowledge of proper burning techniques should be improved. Public awareness campaigns should be promoted at national and local levels.
