The problem:
Krakow is one of the most polluted cities in the EU (8th in 2018), according to the WHO. Citizens formed Krakow Smog Alert in response to this problem, and successfully campaigned for a ban on solid fuel heating – burning things like wood, charcoal, peat or coal. This is one of the main sources of air pollution in the country.
Yet without a ban in smaller cities surrounding Krakow, air pollution levels remain dangerously high.
