The winners of Smogathon 2016 suggested building a large green wall in the centre of Kraków. Based on the modern technologies the artificially placed wall made of metal and moss would clean local air, lower the temperature, retain water, increase biodiversity and serve as a decoration for the city centre [1,2]. The project was not completed due to lack of scientific data on its effectiveness and the weak price and outcomes balance; the city is still searching for more economical and practical solutions [6].
