Green City Solutions is a biotech and IoT startup leading the way in the business of air pollution reduction.

Our company has developed a freestanding solution, called "CityTree", which features a moss culture that naturally absorbs the pollution that occurs in urban environments.
Each unit has the effect of up to 275 traditionally planted urban trees, yet it requires less than 1 % of the space and no groundwork. The CityTrees have a reach of up to 50 m and thanks to IoT technology, solar power and water reservoirs, they only need a few hours of maintenance each year.
