The vibrant coastal city of Rio de Janeiro in Brazil will welcome the global ocean community in 2027 for the next Ocean Decade Conference: a milestone moment to accelerate science-based ocean action and shape the legacy of the Ocean Decade!

Taking place on 7-9 April 2027, this Conference will be co-organised with the Intergovernmental Oceanographic Commission (IOC) of UNESCO as lead agency of the Ocean Decade, the Ministry of Science, Technology and Innovation (MCTI) of Brazil and the City of Rio de Janeiro.

The event will bring together up to 3,000 participants for three days of dialogue, partnership and action, and will have scope for partners to lead satellite events, exhibitions and networking events relevant to the Conference themes throughout the city of Rio on 5-6 April.

Uniting governments, scientists, civil society, Indigenous leaders, youth, the private sector and philanthropy, the 2027 Ocean Decade Conference aims to:

• Showcase and track achievements towards The Barcelona Statement priorities
• Further refine Ocean Decade priorities for the remainder of the Decade on the basis of a solid preparatory process throughout 2026
• Facilitate partnerships and discussions to shape the post-2030 legacy of the Ocean Decade
• Inform dialogue at the 2028 United Nations Ocean Conference and contribute to the post-2030 Agenda dialogue on ocean issues
