View from a green roof in Hamburg
The green roof subsidy programme in Hamburg, Germany started in 2014 and offers financial support for the voluntary creation of green roofs and green facades to the sum of 3,5 million Euro until the end of 2024. Private and public building owners can receive subsidies to cover up to 60% of installation costs, including materials and labor. The subsidy programme is based on the thickness and surface area of the green roof rather than the water retention capacity alone. The programme is part of Hamburg's green roof strategy and the overall strategy for sustainable rainwater management.
