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 ongoing business or to help start new green ones. 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 learning from successful examples, with a view to creating a portfolio of relevant information to replicate 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 characterised according to the type of environmental pressure they address – the pressure generated by fishing, presence of marine litter, changes in the hydrographic conditions, pollution (including 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 in order to make the maritime economy greener in a profitable way, either by introducing innovative techniques/ products or by changing the way economic operators operate in different maritime sectors.
