The Hamburg Green Building Award, presented by the Environment Agency (BUKEA), honoured outstanding green building projects for the third time this year, highlighting Hamburg's commitment to adapting its city to climate change. The basis for this is Hamburg's green roof strategy, which will have been in place for eleven years by 2025 and has made Hamburg a pioneer of green architecture in Germany. Supplemented since 2024 by the green facades strategy, the city is pursuing a clear goal: climate-resilient neighbourhoods with cool places to stay, better water storage and new habitats for animals and plants.

The annual Asphaltsprenger Festival on the PARKS site is now a firm favourite with nature enthusiasts and interested parties. Here you can find out about environmental protection, urban nature and sustainable urban development.

The festival, organised by the Loki Schmidt Foundation and the BürgerStiftung Hamburg, took place at the same time as the Hafengeburtstag. For the fourth time, the PARKS site was transformed into a lively meeting place for environmentalists, families, music fans and the curious - and offered an unparalleled programme on 10 May.

At the heart of the festival is the desire for a city in which nature and people are given more space again. Numerous Hamburg environmental organisations presented themselves at almost 50 stands, providing information about their projects and inviting people to get involved. Here you could not only learn how each individual can contribute to environmental protection, but also become directly active: Whether it was developing digital microscopes to analyse the water from the flood basin, building insect hotels or taking part in the bee trail - a thirst for research and action were expressly encouraged.

A worthy celebration: from 29 May to 9 June 2025, the festival celebrated its 10th anniversary with a particularly festive ten-day edition. Over 50 rooftops throughout Rotterdam opened their doors to visitors, offering spectacular views, extraordinary encounters and a varied cultural programme. Special attractions included guided rooftop tours with music, spoken word performances, architectural tours and even a city beekeeper who shared his knowledge. A rooftop cinema and various concerts in the evening also ensured a varied experience

We are passionate about taking art and encounters to new heights, literally!

That was the motto of our guided tour as part of the ‘Long Day of Urban Nature’ on 21 June. Together with 15 interested people, great local cooperation partners and a few degrees Celsius too many, we explored a total of three roofs in HafenCity.
