On 25 February 2025, from 2:00 PM to 5:00 PM, the expert dialogue "Access not Ownership: Opportunities and Challenges of the Sharing Economy" took place. The event was organized by the Ecologic Institute on behalf of the Berlin Senate Department for Mobility, Transport, Climate Protection, and the Environment (SenMVKU) and was held in Berlin.

In the context of the political goal of strengthening the reuse of used goods, the project aimed at supporting and executing re-use measures in Berlin in order to foster structures and actors in Berlin that bring the used goods market out of its niche. To do so, the project draws on the experience of several predecessor projects including initial pilot tests, networking activities and the opening of the Re-Use Superstore.
