Bermuda and the United Kingdom have signed the Hamilton II Declaration to coordinate efforts for protecting the Sargasso Sea. This initiative builds upon the original Hamilton Declaration signed over a decade ago.
Why it matters
The declaration establishes a framework to secure legally binding protections for the high seas under the United Nations Biodiversity Beyond National Jurisdiction Agreement. It seeks to preserve the region for future generations by aligning international policy with ecological preservation.
The declaration involves a coalition of over 20 non-government organizations alongside sovereign territories. It operates as the foundational process for state parties to eventually formalize protection measures under the BBNJ Agreement.
The players
Bermuda
Bermuda is a British Overseas Territory in the North Atlantic Ocean known for its active role in marine conservation.
United Kingdom
The United Kingdom is a sovereign nation and a formal party to the United Nations Biodiversity Beyond National Jurisdiction Agreement.
European Union
The European Union is an economic and political union that plans to officially join the declaration at the next BBNJ meeting.
The details
The signing in Bermuda includes participation from the Azores, the Bahamas, the Cayman Islands, Monaco, and the Turks & Caicos Islands. It serves as a precursor to the upcoming conference in New York where further international support will be sought.
Timeline
The Hamilton II Declaration was signed on October 19, 2026.
The first BBNJ Conference of Parties is scheduled for January 2027 in New York.
The Big Picture
This effort aligns with the United Nations Biodiversity Beyond National Jurisdiction Agreement to address regulatory gaps in the high seas. It represents a shift toward formalizing marine protection through coordinated international legal frameworks rather than voluntary commitments.
The potential implementation of legally binding protections could restrict commercial activities in the Sargasso Sea to ensure biodiversity. This move may influence future international maritime regulations and shipping protocols in the North Atlantic.
The takeaway
The Hamilton II Declaration highlights how smaller territories are driving global marine policy by building coalitions with larger nations. This collaborative model demonstrates the necessary steps required to move from voluntary agreements to enforceable international environmental law.
What happens next
A further signing ceremony and an official signing by the European Union are scheduled to occur at the first BBNJ Conference of Parties in New York in January 2027.
