SMARTDEC aims to create and develop an Atlantic network of the maritime transport sector to provide the tools, knowledge and structure needed to rapidly meet the challenge of reducing the pollutant emissions of the waterborne transportation in the Atlantic Area (AA). This joint initiative gathers key actors from different regions in Ireland, France, Portugal & Spain that will be organised as hubs with a quadruple helix approach in which research & academia, policy makers, society and the industry (clusters, SMEs & start-ups) will collaborate to develop common strategies to achieve the decarbonisation of the maritime transport sector. Even if some initiatives are being developed world-wide on this, there is still a lack of a well-structured initiative in the AA. SMARTDEC will boost the innovation capacity of decarbonisation of the maritime transport sector by promoting the adoption of promising technological solutions currently available and validated to match with relevant end-users.
