The Eurotowns network aims to address the issues of sustainability, innovation and welfare in small to medium-sized cities, in order to support the achievement of the EU 2030 strategy objectives.

In order to underline the specific scale of those medium-sized cities, their USP has been translated as : "big enough to cope, small enough to care".

All members of the Eurotowns network participate in a General Assembly which compares political and technical achievements.

The Assembly elects an Executive Council every two years, a body that ensures the implementation of the projects carried out by the network.
