IUCN traditionally participates in BBNJ negotiations as an observer providing scientific and legal advisor to States and regional groups, a provider of evidence‑based options for institutional design and convener of expert dialogues and side events. 

IUCN's overarching goal for this final PrepCom is to ensure that it delivers a coherent, ambitious, and operational package of recommendations that will empower COP1 to take meaningful conservation decisions from day one.

At PrepCom 3, IUCN’s engagement will focus on ensuring that the institutions and rules established now will enable a strong, operational, and ambitious BBNJ Agreement. PrepCom III is mandated to finalize recommendations on the institutional architecture for the first COP. IUCN’s objectives include promoting robust governance structures, including:

  • A strong Scientific and Technical Body

  • A transparent and inclusive Clearing‑House Mechanism

  • An effective financial mechanism

  • Effective COP rules of procedure

IUCN willl also work to ensure institutions are science‑based, transparent, and inclusive of Indigenous Peoples, civil society, and scientific networks.
