Strategic Vision and Achivements

Jena is implementing its ‘Smart City Jena’ strategy focused on digital urban transformation as a mid-sized German knowledge city. Through its designation under the ‘Modellprojekte Smart Cities’ (MPSC) federal funding programme, Jena is developing integrated approaches to sustainable mobility, energy transition, and citizen participation — aiming to serve as a replicable model for cities of 100 000–200 000 inhabitants across Germany and Europe.

Challenges

Challenges are defined by cities to clearly express the urban issues they are facing. They describe specific needs and contexts, helping innovators, companies, and organizations understand the problem and propose relevant, tailored solutions.
Jena has not published any challenges yet.

Experimental Capacity

Pilots

Pilots are real-life implementations of selected solutions in cities. They allow stakeholders to test ideas in real conditions, measure their impact, learn from the results, and determine whether the solution can be improved, replicated, or scaled to other contexts.
No pilots have been launched yet for Jena.
