Nearly 90 percent of residents in cities around the world breathe polluted air, which is the single largest environmental health risk, according to the World Health Organization. To address this global problem, Green City Solutions created a mobile installation of specific moss culture that has large surface leaf areas and that can remove pollutants from the air. As Curbed NY reported, this new mossy air filter has been installed in Oslo, Paris, Brussels and Hong Kong. According to the team, CityTree has the same effect as up to 275 trees but requires 99 percent less space and just five percent of the cost.
