About us

The Regional Hubs for Sustainability Strategies (RENN) support actors from civil society, local government, business, politics and administration who want to play a role in sustainable development in Germany. To this end, each hub boosts and connects their initiatives and skills at local and Land level as well as in their respective RENN region. With four regional hubs, RENN.north, RENN.central, RENN.south and RENN.west, the network spans the whole of Germany.

For the second phase of funding (2022–2024), the RENN network totals sixteen RENN partner organisations, one per Land, including four RENN hubs. The RENN Coordination Centre, which is based at the Office of the German Council for Sustainable Development (RNE) in Berlin, is responsible for the overall coordination of the RENN network.

The RENN network is part of the RNE network and plays an integral role in the Joint Action for Sustainable Development, which the RNE coordinates on behalf of the Federal Chancellery and in coordination with the Conference of Federal State Minister-Presidents. The Joint Action for Sustainable Development aims to boost visibility surrounding pre-existing sustainable development engagement in Germany, to further promote this commitment and networking and to empower actors who are yet to play an active role in the sustainability transition. After all, for the implementation of the UN’s 2030 Agenda to succeed, it must enjoy widespread societal support and active participation beyond the federal and Land level. Interested parties are now able to sign up for the Joint Action on the multifunctional online platform. As partners for regional implementation, the RENN will mobilise support and communicate information to boost the Joint Action.

The RENNs’ work is based on the goals of the 2030 Agenda and the 17 Sustainable Development Goals (SDGs), which are also the framework for the German Sustainable Development Strategy. The hubs pool inspiration, ideas, experience and discourse on the topic of sustainability to use as the basis for sustainability activities and networking for a diverse mix of target groups.

Organisation and structure

For the second phase of funding (2022–2024), the RENN network totals sixteen RENN partner organisations, one per Land, including four RENN hubs and the supra-regional RENN Coordination Centre based at the RNE Office in Berlin. As such, the networks spans the whole of Germany.


RENN.north covers the five Länder of Bremen, Hamburg, Lower Saxony, Mecklenburg-Western Pomerania and Schleswig-Holstein.


RENN.central covers the five Länder of Berlin, Brandenburg, Saxony, Saxony-Anhalt and Thuringia.


RENN.south covers the two Länder of Baden-Wuerttemberg und Bavaria


RENN.west covers the four Länder of Hesse, North Rhine-Westphalia, Rhineland-Palatinate and Saarland

First funding phase (2016–2021)

The German Federal Chancellery initially funded the four Regional Hubs for Sustainability Strategies (RENN) for a first project phase from 2016 to 2021. In 2016, the German federal government commissioned the RNE with selecting four RENN hubs, with the RNE consulting the Länder for proposals. This was followed by an official application process. Existing, primarily non-governmental organisations that were already working in the area of sustainability were consequently selected to handle the task of regional networking. The aim here was to avoid creating structural redundancies. A total of 20 partners from the 16 Länder were chosen to make up the RENN network. The RENN Coordination Centre was then set up at the RNE to lead the network.

What concrete form does sustainable development take locally?

This was the topic of discussion for some 200 sustainability actors from all over Germany at the "Berlin RENN.days 2018", which were held on 13 and 14 November 2018. The meeting was marked by inspiring examples, both sobering and galvanising experiences as well as strategies for even broader acceptance of societal change.
