On 14 November 2025, the RE4GREEN EU Social Lab on climate and mobility convened for its fourth in-person workshop at the Museum für Naturkunde in Berlin, an inspiring setting that vividly reflects the history of nature, the environment, and all living and non-living beings. The session was organised by ECSA as part of the ongoing Social Lab process within the RE4GREEN project.

Building on insights and results from earlier meetings, this workshop focused on translating previous reflections into practice, with particular attention to the Do No Significant Harm principle and a constructive review of the micromodules developed within the project. The day provided space for evaluation, co-creation, and forward-looking visioning—encouraging participants to consider how the green transition can be shaped in concrete project contexts.

The unique atmosphere of the Natural History Museum invited us to imagine pathways towards a greener and more harmonious future, fully capturing the spirit of the Social Lab methodology and the broader ambition of RE4GREEN.

We sincerely thank all participants from diverse fields for their valuable perspectives and active engagement throughout the workshop. Special appreciation goes to our colleagues Chrysanthi Bairaktari and François Jost for their excellent organisation and coordination, which made the day both productive and enjoyable.
