In 2027, Heilbronn (DE) will be the European Green Capital, and the European Green Leaf Awards – for smaller cities – will go to Assen (NL) and Siena (IT).
Heilbronn demonstrates a successful intersectoral collaboration of noise, climate and air pollution into its ‘Landscape Plan 2030’ and the city’s ‘Mobility Concept’. Citizen engagement is central, with participatory platforms, awareness campaigns, and protection for quiet areas.
Heilbronn will be granted a financial prize of €600,000. The money will contribute to the city’s effort to implement measures of sustainability and participation to enhance its environmental sustainability as European Green Capital 2027. Heilbronn will succeed 2025 titleholder Vilnius (Lithuania) and 2026 titleholder Guimarães (Portugal).
Both Green Leaf Award winners, Assen and Siena, impressed the jury with their exemplary approaches to engaging their communities in the green transition. Assen and Siena, as European Green Leaf 2027 award winners, will receive a financial prize of €200,000 each.
