Using a bottom-up approach, the project addressed the local stakeholders engaged in different sectors of the maritime economy across all EU regional seas aiming to gather examples of greening traditional business operations or starting new green businesses. This approach included questionnaires and open interviews addressed to industry bodies and associations, port authorities, small and medium-sized enterprises, NGOs, etc. These actions aimed at acquiring the experiences gained from the successful examples in order to create a portfolio with the relevant information for the reproduction of the successful examples elsewhere in the EU, as well as to learn from the unsuccessful examples (understanding/knowing the factors that led to their failure). To increase the relevance of the result for MSFD implementation, the identified examples were characterized according to the type of environmental pressure they address – pressure generated by fishing, the presence of marine litter, changes in hydrographic conditions, pollution or noise, etc. Based on this information, the project identified the ways in which regional, national and EU policies could enable and support such activities. The main objective was to explore the knowledge and experience of the economic actors involved, to make the “blue economy” greener in a profitable way, either by introducing innovative products or by changing the way economic operators operate in the different maritime sectors.
