Since International and European relations often work best within a framework of agreed legal instruments, considerable effort has been devoted to developing a series of conventions and other international and European instruments that promote the conservation of marine biological diversity.
These include:

• Convention on Biological Diversity (CBD)
• EU Common Fisheries Policy
• EC Habitats Directive
  • SAC (Special Areas of Conservation)
• EC Bird Directive
  • SPA (special Protected Areas)
• MPAs (Marine Protected Areas)
• ICZM (Integrated Coastal Zone Management)
• EBM (Ecosystem based Management)
