City Tree

The German company Green City Solutions has created “City Tree”: a bench that cleans the surrounding air. Thanks to its vegetal wall, it naturally filters about 240 tons of pollutants per year. This represents the filtering capacity of a forest of 275 trees. Already installed in London, City Tree is also a monitoring tool, that provides measures and information on air quality.
