In its third edition, the EU Blue Economy Report continues to analyse the scope and size of the Blue Economy in the European Union. It aims at providing support to policymakers and stakeholders in the quest for a sustainable development of oceans, coastal resources and, most notably, to the development and implementation of polices and initiatives under the European Green Deal in line with the new approach for a sustainable Blue Economy. For the purposes of the Report, the Blue Economy includes all those activities that are marine-based or marine-related. Therefore, the Report examines not only established sectors (i.e. those that traditionally contribute to the Blue Economy) but also emerging (those for which reliable data are still developing) and innovative sectors, which bring new opportunities for investment and hold huge potential for the future development of coastal communities. Analyses are provided for the EU as a whole and by sector and industry for each Member State.
