Blue NDC
Challenge

The Paris Agreement has driven progress on global climate action, however, Parties are still not collectively on track towards achieving its purpose and long-term goals.

This fall (2025), countries will submit new plans under the Paris Agreement explaining how they will tackle climate change. These plans are called Nationally Determined Contributions, or NDCs. As the window of opportunity to get back on track narrows, this is our chance to change course and mobilize a crucial untapped resources in the fight agains climate change: the Ocean.

The Blue NDC Challenge is a global call for all ocean nations to place the ocean at the heart of their climate plans ahead of UNFCCC COP30, which Brazile will host in November, 2025. By joining, governments commit to accelerating ocean-based mitigation and adaptation actions that deliver benefits for climate, nature and people.

Depending on their national context, countries can include:

  • Sustainably managing, conserving and restoring coastal and marine ecosystems;
  • Phasing out offshore oil and gas production;
  • Scaling up responsible marine renewable energy;
  • Decarbonizing and adapting maritime industries, like shipping;
  • Fostering sustainable, climate-resilient fisheries and aquaculture.

Voices of support

"Ultimately, industrial marine sectors and natural ecosystems are underused tools in addressing climate change and other development needs. As world leaders gather in Nice and prepare for the United Nations Climate Change Conference in Belém (COP30), they can take inspiration from the Seychelles in championing ocean-based climate action," Wavel Ramkalawan is President of the Republic of Seychelles

"We are pleased to join the Blue NDC Challenge and work alongside COP30 host, Brazil, as well as France, Fiji, the Republic of "Seychelles, Mexico, Palau to highlight the vital role of the ocean in global efforts on climate change. This is an important initiative, and we commend France and Pacific countries in their longstanding leadership on this issue. There are significant opportunities in sustainably managing, conserving and restoring coastal and marine ecosystems, among other blue solutions. We acknowledge the links being drawn between the Paris Agreement and the ocean program this year, as we approach a decade of the Paris Agreement.” Senator Murray Watt, Minister for the Environment, Australia

"For Brazil, the Blue NDC Challenge represents a key opportunity to strengthen ocean-related climate action and to emphasize the essential role of ocean-based solutions in achieving emission reduction targets. Through this initiative Brazil seeks to advance international cooperation on ocean climate action in the lead-up to COP30, and to underscore the need for all countries to fully integrate the ocean into their national climate strategies.” Marina Silva, Brazil Minister for the Environment and Climate Change 🇧🇷

"The ocean was part of our first NDC and the second round is an opportunity to consolidate the role of the ocean in our climate policies. Our perspective covers both adaptation and mitigation, associated with the conservation measures that include climate co-benefits of Marine Protected Areas. Nature based solutions are central in this regard, considering synergies with other processes like the CBD and the 30×30 target.” Julio Cordano, Director of Environment, Climate Change, and Oceans at the Ministry of Foreign Affairs of Chile 🇨🇱

“The ocean already plays a vital role in stabilizing our climate–but it has vast untapped potential to be an even greater part of the solution. From harnessing clean energy like offshore wind to restoring marine ecosystems that store vast amounts of carbon, there are many ways that countries can use ocean-climate solutions to deliver on the Paris Agreement,” said Janis Searles Jones, CEO of Ocean Conservancy. "I thank Brazil for their leadership on the road to COP30. Thank you for launching this Challenge to solidify ocean-based climate solutions as a key part of national climate plans--and to get the resources and assistance needed to make them a reality."

“Ocean-based climate solutions can deliver up to 35% of the emissions reductions needed to keep 1.5°C within reach. But we are running out of time to maximise the ocean’s potential. That’s why countries must place the ocean at the heart of their climate strategies. We applaud Brazil’s leadership in launching the Blue NDC Challenge, this is a vital step to mobilize ambition, support, and coordination to fully integrate the ocean into national climate plans,” Tom Pickerell, Global Director of the Ocean Program at World Resources Institute and Head of the Secretariat for the High Level Panel for a Sustainable Ocean Economy

“The Paris Agreement was the beginning – a promise that ambition would grow over time. Ten years on, the time for promises is now over. The Blue NDC Challenge is how we turn Paris ambition into Belém action, by fully leveraging ocean-based climate action,” Loreley Picourt, Executive Director, Ocean & Climate Platform

“As the host of the next climate conference, Brazil has a unique opportunity to lead by example with an ambitious, science- and nature-based agenda that amplifies the voices of vulnerable communities. Including the ocean in national commitments — and ensuring their implementation — is essential to addressing the climate crisis with the urgency it demands. We see the Blue NDC challenge, and Brazil’s leadership, as crucial steps toward more effective, integrated, and resilient climate solutions,” Marina Corrêa, Oceans Lead at WWF-Brazil

Join the Challenge

When joining the Blue NDC Challenge, countries commit to integrating ocean-based climate solutions into their climate strategies or achieving their NDCs with ocean-climate solutions.

Group-741

This approach is designed to be inclusive, as a way to highlight how ocean-based climate solutions contribute to national climate goals. Stronger, ocean-inclusive NDCs and implementation plans increase climate ambition and send a clear signal to investors and technical partners to unlock finance, technology and other support to accelerate implementation.

Countries joining the Blue NDC Challenge will be supported by a global coalition of partners, including the Ocean Breakthroughs, led by the Marrakech Partnership for Global Climate Action and the UN High Level Climate Champions; and the NDC Partnership, hosted by the World Resources Institute. These partners provide technical assistance, capacity building, and pathways to climate finance to help countries turn commitments into action.
