The Interreg ADRION Programme is an EU programme for funding transnational projects in the field of Innovation, Culture, Environment, Mobility services and Transport in order to enhance economic, social and territorial cohesion in the Adriatic-Ionian area, which covers four Member States (Croatia, Greece, Italy and Slovenia) and four non-Member States (Albania, Bosnia-Herzegovina, Montenegro and Serbia). We have decided to invest 118 M EUR in four priority axes: 1. Support the development of a regional innovation system 2. Promote the sustainable valorisation and preservation of natural and cultural heritage as growth assets 3. Enhance the capacity in transnationally tackling environmental vulnerability, fragmentation, and the safeguarding of ecosystem services 4. Enhance capacity for integrated transport and mobility services and multimodality.
