An idea for the city 
of the future

The idea is as simple as it is satisfying. The City Trees developed by a business startup in Dresden are actually sustainable green advertising panels. They can meet their own needs with rainwater collectors and solar panels that make them totally autonomous and virtually maintenance-free. The manufacturer 
is relying primarily on mosses, whose many tiny leaves offer a much higher level of gas exchange than deciduous trees. One City Tree is designed to absorb about 30 kilograms of carbon dioxide – as much as 20 roadside trees – and 37 grams of particulate matter a year. And they also look good thanks to their evergreen moss and integrated park benches. They are financed by advertising and offer space 
for lettering and QR codes. The project is being monitored by HTW Dresden, TU Dresden and Berlin’s Humboldt Univer­sity. Prototypes are already operating in Saxony, and Berlin is next on the list. A total of 50 City Trees are scheduled to be “planted” in Germany during 2015.
