The Green Belt in Frankfurt am Main spans in the inner area of the city and covers almost a third of the city's wider area which is around 80 square kilometres, around half of which is the city forest (6). In 1991, as stated in the city council's Green Belt Constitution, the Belt has been declared a protected open space while it also outlined the long term goal of securing and developing it (1). The green belt with its landscapes, excursion destinations and the large network of paths is important for the quality of life in Frankfurt and at the same time offers a place of retreat for plants and animals. It is essential for a good urban climate (1).

Details on the roles of the organisations involved in the project

Based on the initial concept of the architect and urban planner Till Behrens, in 1991 the city council of Frankfurt am Main initiated a project year, in which the area and the goals of the Frankfurt Green Belt were to be determined. In the planning process, political actors as well as citizens and representatives of the private sector took part. For the execution of the project plan and the long-term maintenance of the Green Belt, first an internal administrative working group GrünGürtel were created that later formed into the GrünGürtel GmbH that emerged from the former Bundesgartenschau GmbH. Later the inter-agency project group GrünGürtel was created with the contribution of the Environmental Office, the Green Space Office of the city of Frankfurt am Main (6). The project group, employees from the Environmental Department, Green Commission, and the City Planning Office work together on the development and maintenance of the Frankfurt Green Belt (1).

Project implemented in response to ...

... an EU policy or strategy? Unknown
... a national policy or strategy? Yes (Frankfurt, one of 19 communities developing a “Masterplan 100 % Climate Protection“, will play a leading role in reaching Germany’s climate protection objectives (5). Within the above-mentioned plan, the city has committed itself to halving energy consumption by 2050 and covering its remaining energy requirements with renewable energies. By 2050, greenhouse gas emissions will be reduced by 95 percent compared to 1990. An ambitious aim, where everyone, inhabitants, companies, clubs, and institutions, must lend a hand (5).)
... a local policy or strategy? Yes (The city council of Frankfurt am Main unanimously passed the Green Belt Constitution on November 14, 1991. In doing so, it has made the Green Belt Constitution, which consists of four parts, a standard for its actions. Specific information and instructions for the sustainable legal safeguarding of the Green Belt are set out here. (6))
