In late August 2026, the Bundesverband GebäudeGrün e. V. (BuGG) announced the Building Greening Action Week, a nationwide German campaign scheduled for September 14 to 20. The initiative focuses on urban greening and the de-sealing of surfaces through various in-person, online, and hybrid activities designed to facilitate knowledge transfer and encourage practical implementation of green infrastructure.

By mid-September, efforts toward urban climate resilience are being highlighted through the Climate Adaptation Week, a nationwide initiative by the German Federal Ministry for the Environment. In Leipzig, activities include tours of research green roofs, discussions on the “Sponge City” concept to prepare for hot summers, and consultations regarding subsidies for greening projects.
