The 2019 Cycling4Trees challenge, initiated and operated in close collaboration with Siemens Mobility GmbH from July to September 2019 between the teams of Berlin, Cologne, and Munich, was won by team Berlin throughout the whole three months’ challenge. As a result, all three trees, sponsored by Siemens for the winner of each month, were planted in Berlin on November 21st, 2019. The trees found their new home on Falkenseer Chaussee in Spandau and provide for a better climate in the city of Berlin from now on.
