Tree City @ BaumEntscheid

Hybrid Space Lab is developing a visual strategy in support of the climate adaptation law for Berlin “BäumePlus-Gesetz” that is developed by the Berlin NGO BaumEntscheid.

Climate Adaptation @ BaumEntscheid, Berlin, 2025-2026

BaumEntscheid in Berlin is a broad movement comprising members from all political camps, social classes and age groups. BaumEntscheid is a rapidly growing team of dozens of volunteers, including lawyers and experts in the field of urban planning. BaumEntscheid is convinced that a weatherproof city benefits everyone in Berlin.

At least every second street tree is diseased, and for some tree species the figure is as high as 90%. Only every third tree that is felled is replanted. Berlin is becoming hotter, greyer, drier and more dangerous for too many people, especially those on low incomes.

BaumEntscheid wants to make Berlin heat-proof and weatherproof by means of a referendum, so that life in Berlin remains bearable despite heat and extreme weather.
The Berlin Climate Adaptation Act, which BaumEntscheid developed together with experts, is intended to provide the necessary climate adaptation policy so that Berlin remains a healthy and safe city for all of us and for future generations.

BäumePlus Law

BaumEntscheid wants to make Berlin heat-proof and weather-proof by means of a referendum, so that life in Berlin remains bearable despite heat and extreme weather.

The BäumePlus Law is intended to ensure the necessary climate adaptation policy so that Berlin remains a healthy and safe city for all of us and for future generations.
The BäumePlus Law was developed in a broad-based process involving numerous volunteer experts from the fields of science, politics, administration and business, as well as committed citizens and lawyers.

Berliners will vote on the law in a referendum in 2026. If the majority votes in favour, by at least a quarter of all eligible voters, the law will come into force immediately.

In a decision on November 3, 2025, the Berlin House of Representatives passed Germany’s first climate adaptation law in the form of the “BäumePlus-Gesetz” (Tree Plus Law) of the Baumentscheid (Tree Decision) with cross-party support and no dissenting votes in an unprecedented collaboration between referendum, political parties, and politicians.
