Resumed 5th Session of the Intergovernmental Conference (IGC) on Biodiversity Beyond National Jurisdiction (BBNJ) | New York, 20 February – 3 March 2023

The session concluded the global negotiations on the Treaty on the conservation and sustainable use of marine biological diversity of areas beyond national jurisdiction, also known as the Treaty of the High Seas, aiming to protect the ocean, tackle environmental degradation, fight climate change, and prevent biodiversity loss.

date:  17/04/2023

The high seas provide invaluable ecological, economic, social and food security benefits to humanity and are in need of urgent protection. Areas beyond national jurisdiction cover nearly two-thirds of the world's oceans, comprising the high seas and the seabed beyond national jurisdiction. They contain marine resources and biodiversity and provide invaluable ecological, economic, social, cultural, scientific and food-security benefits to humanity. However, they are under mounting pressure from pollution (including noise), overexploitation, climate change and decreasing biodiversity.

Faced with these challenges, and in view of future increasing demands for marine resources for food, medication, minerals and energy, among others, an overwhelming majority of states agreed on the need for a high seas treaty, which takes the form of a new Implementing Agreement under the United Nations Convention on the Law of the Sea (UNCLOS) to protect and sustainably use the resources of these areas. The Agreement will further implement existing principles in UNCLOS to achieve a more holistic management of activities carried out in the high seas. These principles include the duty to cooperate, to protect and preserve the marine environment and to undertake prior impact assessment of activities.

The new treaty will make it possible to establish large-scale marine protected areas on the high seas, which are also necessary to meet the global commitment of the Kunming-Montreal Global Biodiversity Agreement concluded last December to protect at least 30% of the oceans by 2030. For the first time, the treaty will also require assessing the impact of economic activities on biodiversity in the high seas. Developing countries will be supported in their participation in and implementation of the new treaty by a strong capacity-building and marine technology transfer component, funded from a variety of public and private sources and by an equitable mechanism for sharing the potential benefits of marine genetic resources.

The Treaty is the fruit of more than a decade of global engagement to find solutions for this crucial global environmental issue. The EU and its Member States have been leading the BBNJ High Ambition Coalition which played a key role in reaching the agreement. The coalition gathers 52 countries that are committed, at the highest political level, to achieve ambitious actions for the protection of the ocean. It was launched at the One Ocean Summit 2022 in Brest by Commission President von der Leyen together with the French Presidency of the Council.

The Agreement shall enter into force once 60 States have ratified it. The EU will work to ensure this happens rapidly and to help developing countries prepare for its implementation. To this end, the EU has pledged €40 million as part of a Global Ocean Programme and has invited members of the High Ambition Coalition to do the same within their capabilities.
