Policy frameworks

Policy frameworks at various levels, from regional and European to global, provide important mechanisms for achieving a more harmonised understanding of the issue of munitions in the sea. They enable cooperation among stakeholders and help to address risks to the environment, the economy, human health and safety, as well as broader security concerns.

At present, these frameworks show considerable variation in their development, scope and level of implementation. While numerous legal and policy instruments exist, they do not yet form a fully coherent or operational system for proactive munition management. Responsibilities are distributed across different areas of law, including environmental protection, the law of the sea and disarmament regimes, resulting in a fragmented governance landscape. A key limitation is that existing frameworks rarely establish clear mandates for action. In many cases, the removal of munitions in the sea is only triggered where there is an immediate risk to human safety, maritime traffic or critical infrastructure. By contrast, long-term environmental risks or impacts on economic activities such as fisheries or offshore energy do not typically create comparable legal obligations. As a result, responses often remain reactive and case-specific rather than preventive and strategic.

At the same time, coordination between authorities, both within and across countries, is often limited, and responsibilities are not always clearly defined. This further constrains the ability to develop and implement large-scale or cross-border remediation efforts. Despite these challenges, important progress can be observed across different governance levels. At the regional level, cooperation has proven particularly effective in translating broader commitments into practical coordination. The Baltic Sea Region, driven notably by the Baltic Marine Environment Protection Commission (HELCOM) and the Council of the Baltic Sea States, is widely regarded as a leading example of structured and sustained collaboration. At the European level, environmental legislation provides a strong framework for monitoring and addressing pressures on marine ecosystems, while recent initiatives such as the European Ocean Pact (2025) signal growing political ambition to develop a coordinated approach to unexploded ordnance (UXO). At the global level, international agreements establish overarching principles for marine environmental protection and cooperation, but do not provide a dedicated regime for addressing munitions in the sea.

Overall, while a broad set of policy and legal frameworks is in place, a clear regulatory and operational gap remains with regard to the systematic management and remediation of munitions in the sea. At the same time, increasing political attention, technological advances and growing regional experience indicate a gradual shift towards more coordinated approaches. Several initiatives are actively contributing to this development, including projects such as MMinE-SwEEPER, MUNIMAP, MUNI-RISK and REMARCO, which work on advancing legal frameworks, improving coordination and supporting the development of more coherent strategies for addressing munitions in the sea.

Below, you can explore regional, European and global frameworks in more detail. Further information on individual countries is available under Knowledge: Countries.

  • Across Europe, regional sea conventions and cooperation frameworks provide important mechanisms for aligning national efforts and facilitating exchange among coastal states. They play a key role in translating broader environmental obligations into practical coordination at sea-basin level and in fostering dialogue between policy, science and operational actors.

    While their mandates differ, most regional frameworks have, to varying degrees, engaged with the issue of munitions in the sea. This engagement ranges from early-stage knowledge exchange and research cooperation to more advanced forms of coordination, including dedicated expert groups, monitoring activities and the development of regional guidance or action plans.

    Compared to other governance levels, regional cooperation often represents the most operational layer of engagement. It enables the identification of priority areas, the sharing of data on munition locations and encounters, and the integration of risk considerations into maritime activities such as fisheries, offshore energy development and seabed use.

    At the same time, regional frameworks generally do not establish binding obligations for the systematic remediation of munitions in the sea. Their role is primarily to support coordination, improve knowledge and promote precautionary and risk-based management approaches.

    The Baltic Sea Region is widely regarded as a leading example of advanced regional cooperation. Work carried out under the Baltic Marine Environment Protection Commission (HELCOM) and the Council of the Baltic Sea States demonstrates how sustained collaboration, supported by expert groups and political dialogue, can gradually strengthen the management of munitions-related risks.

    In other European sea basins, including the North-East Atlantic, the Mediterranean and the Black Sea, regional organisations are increasingly recognising the issue and integrating it into their broader environmental and maritime policy frameworks. However, the level of institutionalisation and operational activity varies significantly between regions.

    The Munitions in the Sea projects aim to further strengthen the role of regional frameworks. By engaging with them through workshops, joint activities and the development of monitoring strategies and roadmaps, they contribute to building a more consistent and coordinated regional approach.

    Below, you can explore the main regional organisations across the different European sea basins in more detail.

    Baltic Sea

    HELCOM

    HELCOM is an intergovernmental organization bridging policy and science on matters related to the environment of the Baltic Sea. A regional platform for environmental policy making, HELCOM was established in 1974 to protect the marine environment of the Baltic Sea from all sources of pollution. It has 10 Contracting Parties: Denmark, Estonia, the European Union, Finland, Germany, Latvia, Lithuania, Poland, Russia and Sweden.

    Focus Munitions in the Sea

    For over three decades, HELCOM has been addressing the issue of munitions in the sea, among other things through the establishment of dedicated expert groups. Following intensive media coverage at the beginning of the 1990s on the occurrence of dumped chemical munitions in unknown locations within the Helsinki Convention area, the 14th meeting of the Helsinki Commission in 1993 decided to set up the ad hoc Working Group on Dumped Chemical Munitions (HELCOM CHEMU). Its task was to elaborate a report on the dumping locations and effects of chemical weapons in the marine environment.

    At its 2010 Ministerial Meeting, the Helsinki Commission decided to establish an ad hoc HELCOM Expert Group to update and review the existing information on dumped chemical munitions in the Baltic Sea (HELCOM MUNI). The HELCOM MUNI report on Chemical Munitions Dumped in the Baltic Sea was submitted to the 2013 HELCOM Ministerial Meeting in Copenhagen as background information.

    The Terms of Reference (ToR) of the HELCOM Expert Group on Hazardous Submerged Objects (HELCOM EG Submerged) were agreed upon by the HELCOM Heads of Delegation meeting HELCOM HOD 43-2013. HELCOM EG Submerged compiles and assess information about all kinds of hazardous objects and assess the associated risks. The compilation and assessment were used to produce a thematic assessment report on challenges related to warfare materials in the Baltic Sea. In 2022 the Group’s TOR were updated and its mandate extended through 2026.

    The need to address the issue of submerged munitions is also reflected in HELCOM’s 2021 Baltic Sea Action Plan (BSAP), which contains two actions directly related to hazardous submerged objects.  

    HELCOM also contributes to fostering dialogue and shaping regional policies by cooperating with other regional players such as the European Union, for instance through participation in the “Our Baltic” process, and the Council of the Baltic States (CBSS). HELCOM, moreover, actively participates in international projects such as MUNIMAP,  MUNI-RISK  and MMineSwEEPER. Through this role, the organization helps raise awareness, acts as a science-policy interface and ensures that scientific findings are effectively communicated to decision-makers across and beyond the Baltic Sea Region.

    CBSS – Council of the Baltic Sea States

    The Council of the Baltic Sea States (CBSS) is an intergovernmental political forum promoting cooperation and stability in the Baltic Sea Region. Established in 1992 by Baltic Sea Foreign Ministers after the Cold War, it comprises 11 members: Denmark, Estonia, Finland, Germany, Iceland, Latvia, Lithuania, Norway, Poland, Sweden, and the EU.

    Focus Munitions in the Sea

    CBSS began actively coordinating regional dialogue on sea-dumped munitions during the German Presidency of the CBSS (2022–2023), notably through the Kiel Roundtable on Dumped Munitions in the Baltic Sea. This event laid important groundwork for the growing cooperation and practical action seen today, reinforcing the CBSS’s strategic role in facilitating high-level political dialogue on this critical issue—alongside key partners such as the European Commission and HELCOM.

    The Declaration of the 20th CBSS Ministerial Session, held in Wismar, Germany, on 2 June 2023, explicitly acknowledged “the environmental, human safety, security and economic risks emanating from the thousands of tons of conventional and chemical munitions dumped in the Baltic Sea. In addition, they can pose a risk to marine life, fishing and navigation, impede the installation of offshore energy infrastructure, and may negatively impact on aquaculture, tourism and other sectors of the blue economy.”

    Beyond fostering political dialogue, the CBSS Secretariat actively participates in international projects such as MUNI-RISK and MUNIMAP as a communication and political dialogue partner. Through this role, the Secretariat helps raise awareness and ensures that scientific findings are effectively communicated to decision-makers across the Baltic Sea Region. Issue of submerged munitions is regularly raised at the Committee of Senior Officials meetings, Civil Protection Network and EUSBSR PA Secure members are also informed about the progress in the projects and other related developments. 

    Additionally, CBSS Director General has taken part in various expert panels and conferences and contributed to reports and publications, further underlining the organisation’s commitment to maintaining momentum and ensuring that the issue of sea-dumped munitions remains firmly on the regional and international agenda.

    North-East Atlantic

    Logo of the OSPAR Commission

    OSPAR

    OSPAR is the mechanism by which 15 Governments and the European Union cooperate to protect the marine environment of the North-East Atlantic. OSPAR started in 1972 with the Oslo Convention against dumping and was broadened to cover land-based sources of marine pollution and the offshore industry by the Paris Convention of 1974. These two conventions were unified, updated and extended by the 1992 OSPAR Convention. The fifteen Governments are Belgium, Denmark, Finland, France, Germany, Iceland, Ireland, Luxembourg, The Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom. OSPAR is so named because of the original Oslo and Paris Conventions ("OS" for Oslo and "PAR" for Paris).

    Focus Munitions in the Sea

    Under the OSPAR Commission’s work on human activities, dumped chemical and conventional munitions in the North-East Atlantic are recognised as a significant environmental and safety concern stemming from large-scale disposal after the First and Second World Wars. These sea-dumped munitions include bombs, grenades, torpedoes, mines, phosphorus incendiary devices and chemical weapons such as mustard gas. Encounters with these munitions, which are reported centrally under OSPAR Recommendation 2023/02 and displayed in the OSPAR Data and Information Management System, occur widely, especially in areas such as the Channel and southern North Sea, with around 900 encounters reported each year, over half of which involve fishing gear entanglement. These encounters pose direct threats to human health and potential risks to marine organisms and sediments, particularly where toxic agents persist or bioaccumulate.

    OSPAR’s approach focuses on improving knowledge, risk assessment and safe management rather than broad-scale removal, recognising that disturbing munitions can increase hazards and mobilise contaminants. OSPAR Contracting Parties have worked to identify detailed locations of dumpsites and areas with high encounter densities, and to integrate this information into decision-making for seabed activities such as dredging, cable laying, sand and gravel extraction, and offshore renewable energy development. In most cases, leaving munitions undisturbed to disintegrate naturally remains the common management practice, but Contracting Parties are encouraged to consider alternative risk-based options where clusters are identified. By centralising reporting, sharing data and promoting precautionary management, OSPAR aims to mitigate safety risks and protect the marine environment while accommodating the sustainable use of the North-East Atlantic.

    Mediterranean Sea

    UNEP and MAP Logo

    UNEP/MAP

    The Mediterranean Action Plan was established in 1975 as a multilateral environmental agreement within the framework of the United Nations Environment Programme (UNEP) Regional Seas Programme. Mediterranean countries and the European Community endorsed MAP as the institutional framework for cooperation in addressing shared challenges related to marine environmental degradation.

    UNEP/MAP and the Contracting Parties to the Barcelona Convention – 21 Mediterranean countries and the European Union – have progressively developed a uniquely comprehensive institutional, legal, and implementation framework, integrating essential building blocks for sustainability in the Mediterranean.

    Over the past four decades, the UNEP/MAP – Barcelona Convention system has adapted to emerging environmental challenges and contributed to a growing body of knowledge on marine and coastal ecosystems, as well as the interactions between development and the environment in the Mediterranean region.

    Focus Munitions in the Sea

    In accordance with Article 4 of the Protocol for the Prevention and Elimination of Pollution of the Mediterranean Sea by Dumping from Ships and Aircraft or Incineration at Sea (amended 1995), the dumping of wastes or other matter is prohibited. The article provides exceptions for a list of items that may be dumped, subject to strict regulation by legally binding guidelines updated at COP 2017 (Albania) and COP 22 (Slovenia). The list of permitted items includes:

    • dredged material;
    • fish waste or organic materials resulting from the processing of fish and other marine organisms;
    • platforms or other man-made structures at sea;
    • inert, uncontaminated geological materials.

    However, it is recognised that there are legacy areas in the Mediterranean where munitions waste still exists. Therefore, UNEP/MAP seeks to benefit from projects such as MUNI-RISK and MMinE-SwEEPER to raise awareness and utilise state-of-the-art methodologies developed for the remediation of such sites in the region.

    Black Sea

    Logo of the Commission on the Protection of the Black Sea against Pollution

    Black Sea Commission

    The Commission on the Protection of the Black Sea Against Pollution (or Black Sea Commission) is the regional governing body created to implement the Bucharest Convention signed by the six Black Sea coastal countries in 1992 (Bulgaria, Georgia, Romania, Russian Federation, Turkiye and Ukraine). On 31st October 1996, the Black Sea countries also signed the first Black Sea Strategic Action Plan for the Rehabilitation and Protection of the Black Sea, later on amended in Sofia in 2009. This plan defines the policy measures, actions, and activities required to achieve the environmental objectives of the Bucharest Convention. The Black Sea Strategic Action Plan recognises that collective action is required from all Black Sea countries to reduce the impact of pollution on the sea’s ecosystems.

    The areas of work of the Black Sea Commission are, inter alia, to monitor and assess pollution, control pollution from land-based sources, ensure conservation of biological diversity, address environmental safety aspects of shipping, address environmental aspects of management of fisheries and other marine living resources and promote integrated coastal zone management and maritime policy.

    Focus Munitions in the Sea

    Considering that the topic of munitions in the sea becomes burning on the Black Sea agenda and can eventually pose a risk to marine life, fishing and navigation, aquaculture, tourism and other sectors of the blue economy, the BSC Permanent Secretariat is willing to initiate the discussion and contribute to remediating and assessment of submerged marine munitions in  the Black Sea by participating in international projects such as MUNI-RISK and MMinE-SwEEPER as a communication and political dialogue partner. Through this role, the Secretariat will assist in awareness raising and effective communication on the regional level.

  • At the European level, the governance of munitions in the sea is shaped by a combination of environmental legislation and emerging policy initiatives. While there is currently no explicit legal obligation to recover or remediate submerged munitions, the issue is increasingly being addressed within the broader framework of EU environmental and maritime policy.

    EU environmental law establishes a set of converging obligations aimed at protecting marine ecosystems and preventing pollution. Key instruments such as the Water Framework Directive and the Marine Strategy Framework Directive require Member States to identify, monitor and address pressures on the marine environment. These obligations are complemented by the precautionary principle, which requires preventive action where environmental risks are plausible, even in the absence of full scientific certainty.

    Additional legal considerations arise under the Habitats and Birds Directives, particularly where munition sites overlap with protected Natura 2000 areas, as well as from sectoral legislation such as REACH and the Environmental Crime Directive. Together, these instruments provide an important regulatory context for assessing and managing the risks associated with munitions in the sea. However, these frameworks do not directly regulate historical munitions contamination, nor do they establish a dedicated and operational remediation regime. As a result, the management of munitions in the sea remains fragmented and largely dependent on national implementation and interpretation.

    More recent political initiatives indicate a shift towards greater coordination at EU level. In particular, the European Ocean Pact (2025) identifies the development of a comprehensive strategy for unexploded ordnance (UXO) as a flagship action. This initiative recognises UXO in European waters as both an environmental and security concern and calls for the use of advanced detection and disposal technologies. Although the Ocean Pact currently remains a soft-law instrument, it marks an important step towards a more coherent, cross-border approach. It can be seen as a preparatory phase for the possible development of more structured or binding measures in the future.

    Overall, the European framework provides a strong environmental and legal foundation, but a clear gap remains with regard to a dedicated, harmonised regime for the systematic remediation of munitions in the sea.

  • At the global level, the governance of munitions in the sea is not addressed through a single dedicated treaty or institutional framework. Instead, it is shaped by a range of international agreements, technical standards and policy discussions that touch on related issues such as marine environmental protection, chemical weapons governance and maritime safety.

    Existing international conventions establish important overarching principles. The United Nations Convention on the Law of the Sea (UNCLOS) provides the general legal framework for ocean governance and requires states to protect and preserve the marine environment. Similarly, the London Convention and its Protocol regulate the dumping of wastes at sea and aim to prevent marine pollution. In parallel, the Chemical Weapons Convention, implemented by the Organisation for the Prohibition of Chemical Weapons (OPCW), addresses the prohibition and destruction of chemical weapons and has also considered questions related to chemical munitions in the marine environment. Beyond these legal frameworks, operational guidance is provided through technical standards such as the International Mine Action Standards (IMAS), which include provisions for underwater survey, risk assessment and clearance of explosive ordnance.

    Taken together, these instruments form a patchwork of legal obligations, principles and technical guidance. They promote environmental protection, pollution prevention, precaution and international cooperation, but they do not constitute a coherent or operational regime for addressing legacy munitions in the sea. In particular, they do not establish a clear obligation for systematic recovery or remediation. As a result, most practical action continues to take place at national and regional levels, often supported by international research initiatives and technical cooperation.

    The issue has nevertheless gained intermittent attention within the United Nations system, particularly in the context of discussions on oceans, environmental protection and maritime security. Reports of the UN Secretary-General and related General Assembly resolutions have highlighted the long-term risks associated with munitions in the sea and emphasised the importance of continued international cooperation and knowledge exchange.

    Overall, while global frameworks provide an essential foundation of principles and guidance, a significant governance gap remains. At the same time, increasing awareness of environmental and security risks may create new opportunities for the issue to gain greater prominence on the international agenda in the future.
