Wiesbaden celebrates 30 years of the Climate Alliance: A pioneer for environmental protection!
On November 4, 2025, a very special anniversary was celebrated in Wiesbaden: The city can look back on 30 years of membership in the Climate Alliance, the largest European city network for local climate protection. At a festive event in front of the town hall, mayor and head of the environmental department Christiane Hinninger accepted the anniversary certificate, which honors the city's long-standing involvement. Wiesbaden.de reports that Hinninger emphasized how important membership is for the city's future climate protection measures.
Wiesbaden is actively involved in climate protection and is pursuing ambitious goals with the “KLIMA_PLAN Wiesbaden 2045”. This includes a photovoltaic offensive and sustainable building guidelines that promote environmentally conscious construction. In addition, membership in the Climate Alliance enables local strategies to be networked at an international level, including with indigenous communities in the rainforest. Wiesbaden Current highlights that this collaboration is of great importance for the exchange of knowledge and the development of novel ideas.
International networking and visibility
The Climate Alliance brings together around 2,000 cities and communities from over 25 countries who are working together on solutions to the challenges of climate change. According to the city's reports, Wiesbaden's membership gives it the opportunity to take part in various initiatives, such as the renowned “Stadtradeln” campaign. Over 1.1 million cyclists took part in the campaign this year, and many citizens from Wiesbaden took part.
The anniversary certificate was ceremoniously presented by Sarah Mekjian, Head of Communication at the Climate Alliance. Managing director Thomas Brose and chairman Andreas Wolter sent greetings from the UN climate conference COP30 in Belém, Brazil. This connection shows how locally initiated projects and ideas can also gain attention on a global level.
Wiesbaden has not only established itself as a member of an important network, but also plays a pioneering role. The city relies on intensive public relations work and the exchange of best practices to further advance local climate protection and inspire other cities.
