Tallinn (EST)
“The title of European Green Capital for the year 2023 provided significant impetus for the city to accelerate the green transition and apply sustainability principles more extensively. The title year had a clear impact on increasing awareness within the city organisation and fostered the understanding that all daily activities and the provision of city services are linked to the green transition, and sustainability goals must be considered every day.”
Mayor Mr. Jevgeni Ossinovski

Test in Tallinn
Test in Tallinn is one of our innovation programmes initiated by the European Green Capital year 2023, aimed at transforming our city into a living laboratory for sustainable urban solutions. By partnering with technology companies, research institutions, and startups, we provide a real-world environment to test and implement technologies in mobility, energy efficiency and renewable energy.
During the programme we have received 61 applications, approved 28 test projects, and had partners from 18 different countries around the world. We have worked out evaluation criteria, how testing projects contribute to city needs and understand the risks associated to implementations.
This initiative does not only help us achieve our climate goals but also positions Tallinn as a leader in smart city solutions. For instance, we are currently testing satellite data that monitors air quality and emissions, advanced energy management systems for buildings, and various renewable energy projects that could be scaled up to benefit the entire city.
Lessons learned and recommendations
- Helping companies to test requires creative approaches to involve and commit different level city departments. It helps to grow the city’s competence in evaluating innovation and see different possibilities to develop services in greener and cost-effective ways.
- We recommend signing contracts with innovation project parties and taking commitment to scale proven solutions.
- Testing gives the city free technology and enhanced cooperation with start-ups, universities, science parks and other cities.
Budget
It has been a very cost-effective project. The city is covering the salary of the innovation expert responsible for the project. Also, the expenses of promotional activities up to €7,000 per year are included in the city budget.
