Phasing out fossil fuels and investing in renewables will help reduce particulate matter (PM2.5), sulphur dioxide (SO2), and nitrogen dioxide (NO2), which can cause respiratory diseases.

Residential heating emissions can be reduced by insulating buildings, installing efficient boilers, and using clean energy sources for district heating. More information can be found in the Clean Air Tech Hub report on development and greater uptake of cleaner solid fuel household heating solutions, as well as in a report on ‘Increasing policy coherence between bioenergy and clean air policies and measures’ (full report | summary report | policy measures database).
Transport
Nearly 50% of nitrogen oxide emissions across Europe come from road traffic, particularly in urban areas and along busy streets. Diesel cars are among the primary sources.
Traffic emissions can be reduced by:
- Management of traffic and parking spaces, speed limits and low-emission zones
- Switching to clean public transport, walking and biking
- Fleet renewal and shift towards fleet electrification

Agriculture
More than 90% of ammonia emissions to air in the EU come from agriculture: 75% from manure and 20% from inorganic fertiliser.
This leads to eutrophication and acidification of ecosystems, and to the formation of secondary particulate matter with impacts on human health.
Agricultural emissions can be reduced by:
- Closed manure storage and more precise application of manure and fertilisers
- Improved livestock feeding strategies
