More about our finalists

European Green Capital

Debrecen leads the way in sustainability, achieving the highest score among the finalists competing for the European Green Capital 2027 title. The Hungarian city excels in biodiversity, green areas and sustainable land use, as well as in waste and the circular economy. Debrecen has enhanced its urban environment through increasing green spaces by 16% and planting thousands of trees to improve the city’s microclimate.

Benidorm also showcased steady progress toward sustainability with commendable scores in biodiversity, green spaces and the circular economy.

Saint-Quentin was praised for its sustainable air quality and noise management, along with strong results in circular economy and climate change mitigation. Since 2014, the city has achieved notable reductions in air pollution, particularly in ammonia emissions from agriculture and particulate matter from transportation. Its city-wide waste system, featuring colour-coded bins and the innovative ‘CLIIINK’ digital reward programme, earned it extra sustainability points.

Siena excelled in biodiversity, green spaces and land use, with outstanding results also in circular economy. The city has an average of 28 m² of public green spaces per capita and achieved an impressive 61.4% municipal waste recycling rate, while reducing waste sent to landfills to just 1%. With strong scores in air quality, water and climate change mitigation, the city rounds out a solid sustainability case.

Next steps

On 1-2 October 2025, the finalist cities will showcase their environmental vision and governance, as well as their communication strategy in case they win, to a jury panel.

The winners will be announced in this year’s European Green Capital Vilnius (Lithuania) on 2 October 2025 at a festive award ceremony.

The European Green Capital winner will receive a financial award of EUR 600 000 to implement their strategy in cooperation with citizens and stakeholders. The title of European Green Leaf is awarded to one or two cities. Each Green Leaf winner is granted a financial award of EUR 200 000 to help organise activities during their title year and support further transformation.

Benefits for cities

Cities are central to environmental protection. They are hubs of innovation and resources, enabling the efficient implementation of sustainable practices and policies that can significantly reduce the environmental footprint of a large proportion of the population. In addition, urban areas, with their large economies and engaged citizens, are influential leaders in setting the example for environmental policies.

The cities selected for the shortlist are recognised as outstanding examples in sustainability. In addition, all applicant cities receive valuable feedback from independent experts, allowing them to benchmark their efforts against other cities and gain insights on how to improve their environmental performance.

Winners attract significant attention on a European or even international level throughout their title year, boosting tourism, investment and cooperation. There are also long-lasting benefits after their tenure ends. Winning cities can change the perspective of citizens on environmental affairs, creating a momentum for ambitious, fundamental urban transformations that will improve cities permanently and attract further investments. This success can inspire other cities to follow in their footsteps, both regionally and globally, providing a sense of pride for citizens who actively support their city’s evolution.
