Background The amount of particulate matter (PM) and soot – both health and climate damaging pollutants – caused by private wood burning is growing significantly within the EU. In Germany, wood burning is responsible for emissions of 28 000 tonnes of PM10 every year – more than emitted by cars, trucks and motorcycles together. In Denmark, stoves and boilers produce about 70% of overall PM2.5 emissions, which added up to about 20 500 tonnes PM2.5 from residential wood burning in 2013. The issue of particulate matter caused by wood burning has yet to be appropriately addressed. Objectives The LIFE - CLEAN HEAT project aims to significantly reduce PM caused by wood burning in seven EU Member States (by about 15-20% in the medium term). In order to reach this goal, the following objectives will be pursued: Increase awareness and promote better handling/management of stoves; Increase market share of stoves with fewer emissions; Promote alternatives to wood burning; Exchange of information, good governance and more ambitious regulation; Press ahead with development of better stoves/boilers; and Promote labelling and measurement procedures for wood burning stoves. A photo competition, a short film, a mobile exhibition and talks by experts will be organised to raise awareness, and discuss technical and political approaches for a reduction in air pollutants caused by wood burning. The results will be disseminated in workshops in other European countries. Expected results: In total, the project is hoping to reach over 17 million consumers in at least seven European countries: Some 150 000 consumers educated with flyers about using stoves with fewer emissions and improved building efficiency; Some 20 000 people watch the short film on YouTube and at events; Some 60 000 consumers visit the mobile exhibition at events; Some 100 000 people visit the project website; Transfer of activities to at least five other Member States; Comprehensive media work leading to at least 200 articles reaching a wide readership and six million consumers informed by reports on TV and radio; At least 75% of participants stating they are better informed about wood burning, who will then optimise their handling of existing stoves and consider buying better stoves; Several thousand decision-makers and experts better informed through printed material, the mobile exhibition and talks; Networking activities and newsletter reach a further 500 persons all over Europe; and In the medium-to-long term, 10 municipalities include stricter regulations on wood burning in their air pollution policies, the labelling of stoves is brought forward with stricter limit values for particulate matter, and the market share of stoves with fewer emission (including particle filters and eco-labels e.g. ‘Blauer Engel’) increases by 20%.
