CityTrees filter particulates and nitrogen oxides from polluted city air using Internet of Things technology. Sensors detect the climate conditions locally to influence the automated upkeep while solar panels are used as power sources. These urban green spaces offset 240 tons of carbon dioxide emissions annually, which is equivalent to 275 grown trees, but with a lower cost, smaller space occupied, and lower total maintenance. CityTree is created by Green City Solutions, an environmental tech startup.
