How can we transform the city so that it becomes resilient, regenerative and resource-creating?

At a time when urban areas need to radically rethink their energy, environmental and social models, Tenerrdis invites you to take part in its Collaborative Day dedicated to urban ecosystems.

This 2025 edition is part of a dynamic of open innovation. Its ambition is to encourage the emergence of new projects based on feedback and concrete needs expressed by local authorities, companies, developers, researchers and startups.

If you'd like to take part in this challenge and mobilize our network to help you find solutions to your innovation problems, respond to this call for expressions of interest! The Tenerrdis ecosystem will help you to :

Explore organizational, technological and social innovations on major urban issues: energy, resources, logistics, digital technology, circularity, etc.
Identify challenges with high innovation potential, based on existing use cases, experiments or demonstrators.
Co-build your future collaborative projects !

Based on the main themes of the provisional program, we invite you to propose a workshop lasting 1h15. Contributions should include :

A specific issue arising from your challenges or an experiment
An open, collaborative approach
An ambition to spin off or structure an innovative project, to be pursued after the event.
