A tree that has the environmental benefits of a small forest

smart tree (1)

Created by start-up Green City Solutions, CityTrees are covered in moss and lichens which have a massive surface area that can absorb particulate matter, nitrogen dioxide and ozone. The trees’ inventors estimate that a single structure has the environmental benefits of 275 urban trees, but taking up 99% less space and at just 5% of the cost. So far, CityTrees have been rolled out in several cities in countries including Norway, France, Germany, Belgium, Macedonia and Hong Kong. The cost for each tree can be mitigated by the potential for advertising on them. https://greencitysolutions.de/en/
