Executive Summary Blue Growth is the expanding but sustainable use of ocean resources for economic growth, improved livelihoods and ocean ecosystem health. Blue Growth is expected to increase across all sectors in the North Atlantic over the next decade, involving new activities and additional locations for existing activities. Coordinating these activities and ensuring sustainability can present significant challenges. The potential for collaboration across Blue Economy sectors to enhance synergies and avoid conflicts is central to effective marine spatial planning. Well-managed Blue Growth could make important contributions towards achieving United Nations Sustainable Development Goals (SDGs) including SDG2: Zero Hunger; SDG7: Affordable and Clean Energy; SDG8: Decent Work and Economic Growth, and SDG14: a healthy marine environment. Improved science and technology are key to ensuring that Blue Growth is sustainable, particularly in the face of changing climatic and marine conditions. Greater integration between marine sectors is being actively fostered through several ongoing and newly-established initiatives, including the United Nations’ ‘Decade of Ocean Science for Sustainable Development’ and a new international treaty for conservation and sustainable use of marine biological diversity in areas beyond national jurisdiction. The ATLAS project is developing a knowledge base to inform the development of international policies to ensure deep-sea Atlantic resources are managed effectively. This in turn will contribute to the European Commission’s long-term Blue Growth strategy.
