Two years after the 36-hour marathon to finalise the Ocean Biodiversity agreement, delegates gathered once again in the plenary room of the United Nations headquarters in New York to prepare entry into force of the new Treaty. After the successful adoption of the new agreement for the conservation and sustainable use of marine biodiversity of areas beyond national jurisdiction (BBNJ), the United Nations gathered for the Preparatory Commission meeting for entry into force of the new Biodiversity Treaty between April 14-25, 2025. Delegates moved quickly through all topics of the two weeks, marked by general agreement to guide further work towards implementation of the agreement. The Australian National Centre for Ocean Resources and Security (ANCORS) was represented in the negotiations on different national delegations.
Moving quickly through agenda items
Different informal working groups met to discuss the 3 overall “clusters” relating to Governance, Clearinghouse Mechanism and Financial Rules. Broad agreement across the session was seen, with the conference closing early on Friday.
Secretariat and Meetings of the Conference of the Parties (COPs)
On multiple days throughout the two-week conference, discussions evolved around the future Secretariat of BBNJ. Ideas were exchanged about the size and structure, the possible relationship to the UN and headquarter arrangements, its legal capacity and considerations on cooperation with other frameworks and bodies. While all different possible models remain on the table, a tendency towards preference for some link to the UN while having large autonomy, as on the case of the UNFCCC was voiced by the majority of delegations. The seat of the secretariat was discussed and two possible options – Belgium and Chile explored with countries discussing separate elements and naming the importance of certain services, rather than highlighting any preferences for a location.
Initial discussions about the frequency and location of COP meetings began, with ideas to have annual meetings in the initial phase and transition into every two years once yearly discussions are no longer necessary. Budgetary cycles could be independent from the meeting cycles of the COP meetings. The format of meetings was agreed to be ideally in person, unless an emergency arises, where COP meetings could take place virtually with remaining questions on voting. Delegates were more open to virtual (hybrid or online) meetings of subsidiary bodies and intersessionally.
Subsidiary Bodies
As set out in the agreement, BBNJ will establish new institutional arrangements which need further refinement in relation to their size, composition, selection of members and functioning.
The BBBNJ establishes the following subsidiary bodies and mechanisms to support implementation:
Committees
- The Access and Benefit Sharing (ABS) Committee
- The Capacity Building and Transfer of Marine Technology (CBTMT) Committee
- The Finance Committee
- The Implementation and Compliance (ICC) Committee
Bodies & mechanisms
- The Scientific and Technical Body (STB)
- The Clearing-House Mechanism (CHM)
One discussion point was whether to orientate the rules of procedure for the committees on the basis of the rules of procedure for the Conference of the Parties (COP). General agreement was made that they can be applied mutatis mutandis, at least in the initial phase, but that some additional rules will be needed regarding the specifics of each subsidiary body. Most delegations voiced that subsidiary bodies will have limited membership, with expert knowledge, operating in an objective manner. How many members will serve on the bodies will need to meet equitable geographical representation and gender balance, while being small enough to stay functional. Generally, there was agreement of the value of limiting terms of members and hold staggered elections to not renew the entirety of members of a subsidiary body at the same time and keep institutional knowledge. Each committee was discussed separately, and views expressed by delegations. Transparency, inclusivity and cost-efficiency were mentioned as being key when designing these bodies. Intersessional work and technical assistance will be needed from now until the next meeting in August 2025 and beyond.
Preliminary characteristics & modalities of subsidiary bodies based on PrepCom 1 discussions:
Scientific and Technical Body (STB)
Selection criteria: members serving in their expert capacity, nominated by Parties, elected by COP, suitable qualifications (not defined), taking into account need for multidisciplinary expertise, incl. relevant scientific and technical expertise and expertise in relevant traditional knowledge of Indigenous Peoples and local communities, gender balance and equitable geographical representation.
Possibility for roster of experts; and IPLC advisory group (as part of STB or potentially separate).
May include: marine biology, oceanography, Env. Science, Social Science, Law, relevant traditional knowledge of Indigenous Peoples and local communities and other relevant fields (in package elements).
Number of members: majority supports limited number.
Terms of office: preference for limited terms, staggered elections.
Cooperation: Possible engagement with other subsidiary bodies, as well as with other scientific and technical bodies of other agreements, other relevant scientific institutions and other relevant bodies and frameworks.
The Access and Benefit Sharing (ABS) Committee
Selection criteria: appropriate qualifications in related fields (examples from Plant Treaty).
Number of members: 15
Selection: nominated by Parties, elected by COP, gender balance and equitable geographical distribution and providing for representation on the Committee from developing States, incl. from least developed countries, SIDS and from landlocked developing countries.
Terms of office: preference for limited terms, staggered elections.
Cooperation with other Sub-bodies, particularly with the Finance Committee, the STB and the CHM.
The Implementation and Compliance (ICC) Committee
Selection criteria: ‘appropriate qualifications and experience’, nominated by Parties, elected by the COP, gender balance and equitable geographical representation.
Characteristics: non-punitive and non-adversarial.
The Capacity Building and Transfer of Marine Technology (CBTMT) Committee
Selection Criteria: Multidisciplinary expertise, ‘manageable number of members’, gender balance and equitable geographical representation, including from SIDS and landlocked developing countries.
Characteristics: proactive, guidelines for needs assessments, monitoring and review, mobilisation of funds.
Collaboration with IFBs, involvement of civil society and Indigenous Peoples and Local Communities.
Cooperation with CHM and STB, modalities to facilitate cooperation with other IFBs, including under CBD ABS and regarding Digital Sequence Information.
Terms of office: preference for limited terms, staggered elections.
Finance Committee
Selection: appropriate qualifications/expertise, gender balance, equitable geographical distribution.
Cooperation: With other Sub-bodies, particularly with the CBTMT Committee.
Discussions started on the Scientific and Technical Body (STB) regarding its size, composition, selection of members. First ideas about possible size of the STB were exchanged, with preferences ranging between a large body (each state party) and a rather small body (approx. 30 members) with the option to draw upon external knowledge. Greater support was voiced for a smaller body. Most delegations refrained from naming specific expertise, with general agreement on a broad and multidisciplinary body with the option to draw on external expertise from a roster of experts (or establish working groups on specific issues, where needed). Questions remain as to how to select the experts to reflect the required diversity, expertise and equitable geographical representation and gender balance. The idea was raised to have an Indigenous Peoples and local communities Advisory group, which could also be a standalone group to advise more generally on all aspects of the agreement – not limited to recommendations to the STB. This could be a way to allow self-nominations of traditional knowledge holders, who, as mentioned in a side event on traditional knowledge, generally nominate themselves and would not serve in their positions when ‘nominated by Parties’, as it is the case for members of all subsidiary bodies.
The Access and Benefit Sharing (ABS) Committee has its number of 15 members established in the Treaty. As the aim of the committee is to support access and benefit sharing of marine genetic resources (MGRs), experiences from other agreements, including the Plant Treaty on Genetic Resources and interlinkages with other bodies and frameworks under the Convention on Biological Diversity (CBD) will be needed.
The Capacity Building and the Transfer of Marine Technology (CBTMT) Committee is meant to incorporate multidisciplinary expertise, act proactively, and assist in developing guidelines for needs assessments, as well as in monitoring and review, and mobilisation of funds. Cooperation with other sub bodies, in particular with the Clearing-House Mechanism and the Scientific and Technical Body will be crucial. Such collaboration will also be needed with other frameworks and bodies will be crucial, including under the Convention on Biological Diversity, as well as the involvement of civil society and Indigenous Peoples and Local Communities, When considering the composition of the CBTMT committee, it was highlighted by delegates to keep it to a “manageable number”, while ensuring gender balance and equitable geographical representation, including from different States groups, such as Small Island Developing States (SIDS), Least Developed Countries (LDCs) and Landlocked Developing Countries (LLDCs).
The Implementation and Compliance Committee (ICC) is supposed to facilitate the success of the agreement after its entry into force. While there is agreement that such a committee cannot punish non-compliance and should rather serve in a non-punitive and non-adversarial manner, details about composition in regard to conflicts of interest, and how to portray the special circumstance of SIDS, and situations of LDCS and LLDCs, as well as represent gender balance and equitable geographical distribution will still require further deliberation.
The Nervous System of the BBNJ Agreement – the Clearing-House Mechanism (CHM)
The Clearing-House Mechanism will be central for implementation of the BBNJ agreement and ensure transparency and accountability. As defined in the BBNJ Agreement, such as mechanism aims to be a centralised infrastructure, and associated practices, that facilitate the digital exchange of information among diverse stakeholders, while enabling a broader set of users to directly register and access information. The Clearing-House Mechanism (CHM) was discussed at several days of the conference session. While not mandated for COP1, delegations voiced the need for the CHM to be set up and ready as soon as the agreement enters into force. While it is clear that a cost-effective design is preferred and interoperability will be needed, technical details will eventually require technical experts to figure out the nitty-gritty part of the agreement. Ideas by Parties included a multilingual, interoperable design of the CHM and to guarantee special requirements to State Parties, sustained capacity building, a dedicated section of the mechanism for SIDS in form of an individual tab on the website. It is envisioned to serve as a centralised platform for ABS, generate the batch identifier for MGRs and match CBTMT needs with available capacity. To carry out its functions, it will need to be appropriately financed, include human resources and expertise and will need to effectively collaborate with other subsidiary bodies, as well as with other international frameworks and bodies. Moreover, it is envisioned to facilitate access to traditional knowledge (TK) of IPLCs. An incremental and phased approach might be needed to meet the expectations the CHM sets out. A pilot or interim phase was suggested by Parties to begin with the design and test it before entry into force of the agreement in order to ensure smooth operation when 60 countries have ratified. The idea was raised to establish intersessional work to further prepare the technicalities, with formalities of such a group yet to be decided. Prior to the next PrepCom Meeting in August, the Secretariat will provide a flowchart explaining data flows and interlinkages of the CHM with other bodies.
Funding implementation
It is well understood that the implementation of the BBNJ agreement will require initial and consistent long-term financing. Across the two weeks, preliminary discussions took place on the Finance committee, financial rules and a Memorandum of Understanding (MoU) with the Global Environment Facility (GEF). Prior to the session, the Co-chairs provided an overview of different models, which could serve as potential examples – including options to be independent (as in the case of the ISA) versus incorporated into the UN system, with accountability over financial issues to the UN General Secretary (like with UNFCCC), or the head of the secretariat (as the Basel/Stockholm/Rotterdam and Minamata model), or the option to have a trust fund, managed by a different organisation, as in the case of the CBD (see aid to discussions provided by UNDOALOS). The model to which the financial rules will apply, therefore will depend on the model which is chosen for the Secretariat. Delegates highlighted the need for finance to be predictable, new, and additional, with effective participation of recipient countries, accounting for special requirements of SIDS. Regarding the Special fund, inspiration can be drawn from other instruments and the importance of minimising administrative burden and building on experience of trust funds was voiced. Further intersessional work on financial resources and the financial mechanism will be needed, also in regard to the ecological fund (52.5).
Cooperation with other institutions
BBNJ will need to find its place alongside already existing frameworks and bodies covering different geographical areas and sectors of international waters and biodiversity governance. Other IFBs, including the the Convention on Biological Diversity (CBD), the Food and Agriculture Organisation (FAO), the International Seabed Authority (ISA), the United Nations Environmental Programme (UNEP), the North East Atlantic Fisheries Commission (NEAFC) and the Western and Central Pacific Fisheries Commission (WCPFC) were present and participated in discussions in the plenary and in side events on how to “not undermine”, and still “enhance cooperation and coordination”. Constructive contributions to the debate included examples of cooperation with other bodies and existing instruments that may provide examples of establishing links or examples of data needed for BBNJ (such as the CBD CHM on ABS and biosafety). Parties agreed to BBNJ being mutually supportive and non-duplicative.

Looking ahead – Unresolved Issues and what to expect from the Intersessional Period & PrepCom2.
Further clarity will be needed in how to represent equitable geographical representation in the different committees of the agreement and whether this implies the individual person being represented from a specific group (e.g. women, SIDS, or traditional knowledge holders) or whether focus should be put on their interests and knowledge to be represented in these bodies. Suggestions included representing the 5 regions of the UN (Africa, Asia, Eastern Europe, Latin America and the Caribbean and the Western Europe and Other States), some States called for additional seats for specific groups of States, including SIDS, LDCs, LLDCs and archipelagic States, as well as for representatives of traditional knowledge of Indigenous Peoples and local communities. Discussions started with preliminary views on how interaction among the Secretariat, the CHM and the subsidiary bodies, as well as their interaction with other bodies could take shape. While some ideas were flagged, including to link scientific and technical bodies among themselves, having data exchanges among different CHMs, or the direct interaction between secretariats through MoUs or also informally, a concrete roadmap how BBNJ could be the catalyst for cooperation remains to be thought through.
Open questions also remain regarding traditional knowledge of Indigenous Peoples and Local Communities (IPLCs) and interaction in subsidiary bodies, such as the STB. The idea for an advisory group was voiced to provide recommendations and support implementation of the treaty. Discussions surrounding the representation of traditional knowledge holders pointed to the preference for self-nomination (as opposed to being nominated by others, as foreseen in the BBNJ text – “nominated by Parties”), which the advisory group could provide for.
The Secretariat will develop a number of materials in the intersessional period in the lead-up of PrepCom2.
- Matrix for criteria for the Secretariat
- Flow chart for CHM
- Working group for CHM
The Upcoming PrepCom is scheduled for 18-29th August, 2025, in New York, where remaining issues will be taken up, such as to further elaborate on the issues of cooperation and coordination with other bodies. A new document, based on PrepCom1 discussions will be prepared by the Secretariat, serving as a basis for discussions for the upcoming meeting.
