Adoption and diffusion of marine litter clean-up technologies across European seas: Legal, institutional and financial drivers and barriers

This study reviews existing legal, institutional and policy tools and frameworks, relevant to the introduction and adoption of new marine litter clean-up technologies in two regional European seas, the Mediterranean and the Baltic. A combination of desk studies in six countries bordering the Baltic (Estonia, Germany, Sweden) and the Mediterranean (Greece, Italy, Tunisia), and interviews with experts and stakeholders, is used to identify key drivers and barriers to the adoption and diffusion of marine litter technologies. The main conclusion of the study is that the most influential pieces of legislation relevant to marine litter management are top-down EU policies, often forming the basis of regional and national plans. Moreover, the study finds that several drivers of marine litter technologies may at the same time be critical barriers. These factors include public awareness, consumer behaviour, enforcement of legislation, and the rise of SMEs engaged in recycling and eco-labelling of marine litter.Sofia Frantzi, Roy Brouwer, Emma Watkins, Pieter van Beukering, Maria Conceiçao Cunha, Hanna Dijkstra, Sem Duijndam, Hela Jaziri, Ikechukwu Charles Okoli, Mia Pantzar, Ignacio Rada Cotera, Katrin Rehdanz, Karsten Seidel, George Triantaphyllidis NOTE: Roy Brouwer is also with the Department of Economics and the Water Institute, University of Waterloo, 200 University Avenue West, Waterloo, Ontario N2L 3G1, Canad
