Carbon to Sea is proud to join Woods Hole Oceanographic Institution, Scripps Institution of Oceanography, and many other grantees and partners at the Ocean Pavilion in COP30 Brazil’s Blue Zone.

Located within the COP30 Blue Zone, the Ocean Pavilion will once again serve as the central hub for delegates to exchange ideas on how to address the climate crisis by leveraging marine science and ocean-based solutions. This year’s pavilion highlights the interconnectedness of the ocean and forests, emphasizing the unique setting of Belém—at the mouth of the Amazon River, where the rainforest meets the sea—and the essential role of both ecosystems in sustaining planetary health.

“This year has already seen important progress on advancing ocean-based carbon removal solutions into broader conversations on the health of our oceans and climate,” said Diane Hoskins, Carbon to Sea’s Director of Global Policy. “This is an important opportunity to represent the fast-growing field of mCDR at COP30 and connect with partners who share our goal of promoting rigorous science and innovation to protect our oceans.”

The 2025 Ocean Pavilion will feature nearly 60 presentations, keynote addresses, and in-depth discussions organized around key themes including Ocean Life and Biodiversity, Blue Economy and Finance, Ocean Justice and Equity, and Forest to Sea. Visitors will be able to meet with scientists, thought leaders, and the next generation of students actively working toward solutions for the planet’s most pressing environmental challenges. Pavilion sessions will also deliver a status report on global ocean issues expected to be addressed at COP30 and renew calls for enhanced ocean observing systems—critical to closing data gaps on sea-level rise, ocean warming, ocean acidification, deoxygenation, and climate impacts on ecosystems and biodiversity.

This year, Ocean Pavilion partners will also present the Belém Ocean Declaration, calling on nations to take concrete steps to safeguard the ocean and the communities that depend on it. The declaration also calls on leaders to recognize oceans and forests as twin pillars of planetary stability and to urgently integrate ocean protection and solutions into global climate strategies, biodiversity goals, and sustainable development for a resilient, equitable future.

COP30 follows a year of notable progress on the global ocean agenda. The Third UN Ocean Conference, held in Nice, France, in June 2025, produced the Nice Action Plan and the Blue NDC Challenge, advancing integration of ocean-based solutions into national climate commitments. In September, the UN Agreement on Marine Biological Diversity of Areas Beyond National Jurisdiction (BBNJ) achieved the 60 ratifications needed to enter into force, creating new opportunities for global cooperation on high-seas conservation.
