Green City Solutions



Our vision is a world in which people in cities can live healthily. We want to create living conditions that allow all people around the world to permanently have cleaner air to breathe.





Mosses for cleaner air

Different types of moss bind environmental toxins such as particulate matter and nitrogen oxides while producing oxygen at the same time.

Cutting edge IoT technology

Integrated IoT technology delivers comprehensive information on performance and status as well as environmental data on the CityTree’s surroundings.

Variable ventilation

Controllable ventilation technology allows airflow to be intensified, meaning that the filter effect can be increased as required.

Optimum watering

Water provision is either connected or independent, thanks to a fully automated irrigation system.

Energy provision

Energy can be provided independently via solar panels (if necessary with additional fuel cell), or via a grid connection.

Pleasant cooling effect

Mosses store large quantities of moisture, and the considerably increased evaporation surface creates an immense cooling effect.
