Berlin's big environmental festival at the Brandenburg Gate with organic gastronomy and stage program
The UMWELTFESTIVAL by GRÜNE LIGA Berlin has been held annually at the Brandenburg Gate since the mid-1990s – one of Berlin's most symbolic addresses. The Straße des 17. Juni, leading from the Brandenburg Gate through the Tiergarten towards the Victory Column, becomes a festival mile for one day with hundreds of stands, several stages, hands-on workshops, and information booths. GRÜNE LIGA Berlin is the Berlin state association of a nationwide network of ecological clubs and initiatives – its sponsorship ensures a clearly defined environmental profile that is both politically and educationally anchored.
Environmental associations, ecological companies, initiatives from sustainable mobility (cycling, rail, car sharing), organic farming, the energy transition, and climate protection and education present themselves on the festival mile. A characteristic feature of the festival is the hands-on approach: at many stands, you can try out materials, participate in workshops, or apply knowledge directly. This is not a passive trade fair format, but an experience-based environmental arena.
The stages feature a mix of live music, dance groups, talk rounds with female environmental activists, scientists, and politicians, as well as programs for children. Thematic focuses are set anew each year – in 2026, it is soil: its diversity, its function as a CO2 sink and water reservoir, its importance for agriculture, food, and climate. The topic ties into the UN's efforts to establish the "International Year of Soil" as an ongoing task.
The gastronomic offerings at the UMWELTFESTIVAL are consistently organic: stands with organic products from the Berlin-Brandenburg region, vegetarian and vegan specialties, fair-trade coffee, regional juices. Visitors to the festival can also enjoy a culinary day trip through Berlin's sustainable food scene – a concept that has long been standard in Berlin, but is implemented particularly consistently at the UMWELTFESTIVAL.
The 2026 edition puts the topic of soil in the spotlight – a focus designed to highlight the diversity of soil functions: soil as a CO2 sink, water reservoir, nutrient base for agriculture and food, and habitat for billions of organisms. Exhibitors and program items will address the topic accordingly, from soil analysis and permaculture to the debate on soil sealing in Berlin.
The festival is designed as a family event and is also politically ambitious – GRÜNE LIGA Berlin also uses the date to make current environmental policy demands visible. Visitors to the festival typically combine information, hands-on stations, culinary offerings, and stage performances. The festival mile can be walked in two to three hours at a leisurely pace.
The topic of soil runs through all stages, stands, and workshop stations: soil diversity, soil life, sealing, soil degradation, regenerative agriculture, soil as a CO2 sink and water reservoir. Exhibitors will bring appropriately curated content and hands-on materials.
The full stage program and exhibitor list for 2026 will be published in advance on grueneliga-berlin.de.
