For the participating mayors, sustainability is a top-level issue. As political representatives, they are making a special effort towards sustainable development in their cities. Through this dialogue format, they exchange insights on strategies and measures related to sustainable development. They provide key impulses for municipal sustainability policy and sustainable urban development at a national level through their joint recommendations and policy papers. The RNE has facilitated this dialogue process.

Strategic cornerstones for sustainable development in municipalities
To provide a basis for shared dialogue, the participating mayors have laid out a set of strategic cornerstones for sustainable development in municipalities. In doing so, they voice their commitment to the 2030 Agenda and its Sustainable Development Goals as well as the sustainable development goals Germany has set itself. They also make a firm commitment to the goal of achieving climate neutrality and maintaining the 1.5 °C target.
The cornerstones form the strategic foundation of their shared understanding of sustainable urban development. The participating mayors base their own approaches to policymaking on these and thereby provide important impulses for municipal sustainability policy throughout Germany.
At the heart of the dialogue format and of the cornerstones is the principle that this is a top-level issue. Because sustainable development calls for responsible leadership and clear decisions, both regarding sustainability goals and when conflicts arise between equally important targets or regarding the setting of priorities.
The current third version of the cornerstones was published in November 2019.

Meetings and events of the “Sustainability City” dialogue
Meetings which generally take place once a year are the primary focus of the joint dialogue. These non-public discussions provide a framework in which the participants can engage in open and constructive exchange of ideas related to this topic area as well as the challenges of implementation. Joint resolutions are discussed and the groundwork is laid for the dialogue’s ongoing work. The “Sustainable City” dialogue will be continued in 2020 as well.
Additional joint events supplement the annual meetings. On 20 February 2019 numerous members of the Bundestag and mayors came together in Berlin for the first “Sustainable City” parliamentary evening.
