Move over, Vilnius, there’s a new green star in town. The European Commission has just crowned Heilbronn, Germany, as Europe’s Green Capital for 2027, recognizing the city’s impressive commitment to sustainability, clean air, and climate-frifinishly living.
The award, announced at a ceremony in Vilnius (this year’s titleholder), celebrates cities that lead the way in urban environmental innovation. Heilbronn earned top marks for its air and water quality, climate adaptation, and circular economy initiatives, plus its smart approach to tackling noise pollution through long-term projects like the Landscape Plan 2030 and Mobility Concept.
The city will also receive €600,000 to boost its ongoing sustainability efforts, from expanding green spaces to engaging locals through community-led environmental programs. With its ambitious 2035 tarobtains and collaborative regional partnerships, Heilbronn is proving that you don’t have to be a capital city to lead Europe’s green revolution.
