Reversing biodiversity loss requires integrating biodiversity concerns into all relevant environmental and non-environmental policies across various levels. Task 6.1 of MSP4BIO aimed to understand the status of biodiversity mainstreaming in marine policies and sectors in the EU, highlighting barriers and levers to this process. An empirical study covering eight EU member states and four Regional Sea Conventions used interviews, workshops, and policy document analyses to assess how biodiversity is addressed in policy making. Despite the EU’s ambition to restore and remediate biodiversity impacts, significant gaps in implementation persist. The study identified key barriers such as conflicting policy objectives, inflexible frameworks, inadequate monitoring, and poor coordination, but also highlighted opportunities through increased scientific understanding, public opinion, and binding EU legislation.
