The BLUEAIR project aims at enhancing the institutional capacities of ADRION countries and regions in the definition of a common approach towards the implementation of the S3 policy on Sustainable Blue Economy at macro-regional level. Based on the Community Manifesto, the BLUEAIR Innovation Community is meant to be a strategic network of quadruple helix players sharing the long-term goal of coordinating initiatives and cooperating to the definition of new common actions for pushing a Sustainable Blue Economy in the Adriatic-Ionian area. One of the Community assets is the Database of blue transregional solutions (https://blueair-solutions.sf.bg.ac.rs/), enabling the transregional matchmaking between providers/seekers of blue technical solutions with a transregional impact. The BLUEAIR project (Blue Growth Smart Adriatic Ionian S3 – BLUEAIR adrioninterreg.eu) is financed by the Interreg ADRION Programme 2014-2020 and will end in July 2023.
