The North East Atlantic Fisheries Commission (NEAFC) is the RFMO for the North East Atlantic. The area stretches from the southern tip of Greenland, east to the Barents Sea, and south to Portugal. Its objective is the long-term conservation and optimum utilisation of the fishery resources in the Convention Area. There are 5 contracting partners, Denmark (for Faroe Islands and Greenland), the European Union, Iceland, Norway and the Russian Federation, with 6 cooperating Non-Contracting parties, Bahamas, Canada, Curacao, Liberia, New Zealand and Panama.

The European Coast Guard Functions Forum (ECGFF) is a self-governing, non-binding, voluntary, independent and non-political forum bringing together the Coast Guard authorities from 25 EU Member States and Schengen associated countries, as well as representatives of the EU institutions and bodies with competencies related to EU CG Functions. Since its establishment in 2009 the European Commission and EU Agencies, have supported the ECGFF. The rotating chair, supported by a secretariat, governs the Forum with responsibility to implement the annual programme.

The Convention for the Conservation of Salmon in the North Atlantic Ocean (1983) created the intergovernmental organization NASCO (North Atlantic Salmon Conservation Organization) with the objective to conserve, restore, enhance and rationally manage wild Atlantic salmon. It created a large, protected zone, free of fisheries targeting Atlantic salmon in most areas beyond 12 nm from the coast. NASCO has six Parties: Canada, Denmark (in respect of the Faroe Islands & Greenland), the European Union, Norway, the Russian Federation, and the United States of America. France (in respect of St.Pierre & Miquelon) attends as an observer. Iceland withdrew in 2009.

Denmark including Greenland and the Faroe island, Iceland, Finland including Åland island, Sweden and Norway are parties to this agreement, which covers mutual notification, assistance and aerial surveillance of oil and other chemicals at sea. Very few countries have sufficient resources for combating oil spills and other pollution incidents on their own, and for that reason, it is important that nations cooperate closely with other nations on mutual assistance.

The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) was established by international convention in 1982 with the objective of conserving Antarctic marine life. This was in response to increasing commercial interest in Antarctic krill resources, a keystone component of the Antarctic ecosystem and a history of over-exploitation of several other marine resources in the Southern Ocean. CCAMLR is an international commission with 26 Members, and a further 10 countries have acceded to the Convention. Based on the best available scientific information, the Commission agrees a set of conservation measures that determine the use of marine living resources in the Antarctic.

The Bonn Agreement is the mechanism by which ten Governments, together with the European Union, cooperate in dealing with pollution of the North Sea by oil and other harmful substances. The signatories to the Agreement are the Governments of Belgium, Denmark, France, Germany, Ireland, Netherlands, Norway, Sweden, the UK, and the European Union. Spain joined as a Contracting Party in 2019.

The Baltic Sea Task Force on Organised Crime (BSTF-OC) was created in 1996 in Visby (Sweden) through a decision of the Heads of Governments of the Baltic Sea States.

BALTFISH was initiated in 2009 as a flagship project within the EU Strategy for the Baltic Sea Region, EUSBSR. A Memorandum of Understanding was signed in December 2013 by the ministers in the eight member states in the Baltic Sea Region, and thus changing the status of BALTFISH from a flagship project to a permanent fisheries forum. BALTFISH works on two levels. There is a high-level group (HLG) composed of the Member States fisheries directors and invited officials from the European Commission. There is also the BALTFISH Forum Seminar composed of representatives from Member States, the European Commission and the Baltic Sea Advisory Council as well as representatives from other relevant stakeholders in the Baltic Sea fisheries.

The Baltic Sea Region Border Control Cooperation (BSRBCC) is a flexible regional tool for daily inter-agency interaction in the field of environmental protection. It also aims to combat cross-border crime in the Baltic Sea region, with a particular focus on the maritime environment. Cooperation Partners are Police, Border Guards, Coast Guards and Customs Authorities. The BSRBCC Border Guard Chiefs meet annually and is responsible for the cooperation initiative, and approving the operational strategy. It also has an operational and economic mandate for cooperation. The BSRBCC presidency, which is for one year, is supported by a secretariat, which includes representatives from the last, current and next Presidency, thereby ensuring continuity. The Baltic Border Committee (BBC) prepares and implements the cooperation strategy through joint operations, where national representatives integrate national action and local cooperation into wider cooperation as necessary. Each MS operates a 24/7 National Coordination Centre (NCC), whilst the Presidency maintains an International Coordination Centre (ICC).

The ARHC aims to promote technical cooperation in the domain of hydrographic surveying, marine cartography and nautical information as well as examining the implications in the Arctic Ocean Region of matters of general interest. It also aims to stimulate the widening of hydrographic activity in the Arctic Ocean Region and encourage seeking technical advice and assistance in establishing and strengthening hydrographic capabilities. It helps to define the needs for new hydrographic products and services, facilitates information exchange, and aids in the planning and organization of hydrographic activities. The following are member countries of the ARHC: Canada, Denmark, Norway, Russia, United States of America, and Iceland.
