In the summer of 2025, the state capital of Mainz was included in the "Blue Green City Coaching" research and development project. This project is funded by the Federal Ministry for the Environment, Climate Protection, Nature Conservation, and Nuclear Safety as part of the Natural Climate Protection Action Program (ANK) and is supported in its implementation by the Federal Environment Agency. The German Association of Cities also supports the project. The aim of the project is to establish blue-green infrastructure as an effective tool for adapting to the consequences of climate change in cities.
