The global momentum for ocean–climate integration reached a historic milestone at COP30 in Belém, where 17 Nations signed on to the Blue NDC Challenge, signaling a transformative shift in how countries embed marine systems into climate action. This initiative seeks to mainstream ocean-based solutions into Nationally Determined Contributions (NDCs) and expedite their implementation, with countries such as France and Brazil leading the way and new members such as Belgium, Cambodia, Canada, Indonesia, Portugal, and Singapore joining the coalition.

Climate and ocean governance have advanced significantly with the release of the “Blue Package,” an integrated plan to promote marine conservation, ocean renewable energy, aquatic food, shipping decarbonization, and sustainable coastal tourism. The project acknowledges that achieving global climate goals is inextricably linked to ocean health, building on growing political momentum worldwide.

Why Are Nations Increasing Ocean Integration in Climate Plans?

With 17 Nations signed on to the Blue NDC Challenge, leaders are addressing critical gaps in existing climate strategies.

Key reasons include:

• Ocean as a climate stabilizer: Over 90% of surplus heat and over a third of CO₂ produced by humans are absorbed by the ocean, which acts as a climate stabilizer.
• Underutilized climate solutions: Despite the potential to reduce global emissions by up to 35% by 2050, ocean-sector mitigation currently accounts for only 12% of NDC commitments.
• Growing ocean opportunity gap: Ocean-based action receives less than 1% of global climate investment.
• Growing climate vulnerabilities: Millions of livelihoods are at risk due to rising sea levels, coastal erosion, declining fish populations, and biodiversity loss.

Countries understand that global climate targets cannot be achieved without incorporating ocean ecosystems and industry into climate policies.

How Will the New Ocean Taskforce Support Implementation?

The launch of the Blue NDC Implementation Taskforce, strengthened as 17 Nations sign on to the Blue NDC Challenge, aims to close longstanding gaps in marine climate action.

Its support framework includes:

• Mobilising political leadership: Uniting world leaders and ministers to support ocean-climate agendas.
• Unlocking finance: Increasing public and private investment opportunities for sustainable maritime enterprises, offshore renewable energy, and blue carbon initiatives.
• Technical support: Assisting nations in updating their NDCs with practical ocean paths.
• Promoting cross-sector coordination: Coordinating initiatives across the Rio Conventions’ frameworks for sustainable development, climate change, and biodiversity.

Leaders emphasized that offshore wind, zero-emission shipping, sustainable fisheries, and resilient coastal tourism may fuel low-carbon growth.

What Challenges Must Countries Overcome to Deliver Blue NDCs?

Despite the significant momentum signaled as 17 Nations signed on to the Blue NDC Challenge, significant barriers remain:

• Mitigation gaps: Because adaptation is prioritized in most NDCs, prospects for mitigation in ocean sectors remain undeveloped.
• Equity concerns: Coastal and Indigenous populations are not adequately supported, with only 13% of ocean acts mentioning equity.
• Low climate finance flows: Despite the revolutionary potential of ocean initiatives, they continue to get minimal support.
• Underrepresentation of key sectors: conservation initiatives like mangroves and seagrass beds are still far behind offshore renewables, aquatic food, and shipping decarbonization.

Officials emphasized that greater multilateral cooperation and creative financing will be necessary to go from intention to implementation.

What Does the Blue Package Aim to Achieve?

Unveiled alongside the announcement that 17 Nations signed on to the Blue NDC Challenge, the Blue Package is a solutions-driven roadmap organized around five Ocean Breakthroughs:

• Marine conservation: Protecting biodiversity and extending protected areas.
• Aquatic food systems: Increasing sustainable aquaculture and lowering fishery emissions.
• Ocean renewable energy: Accelerating the development of offshore tidal and wind power.
• Shipping decarbonization: Making the switch to vessels and fuels with zero emissions for marine transportation.
• Sustainable coastal tourism: Ensuring nature-positive tourism models that safeguard marine habitats is a key component.

Additionally, this package encourages non-state players to coordinate their activities with national objectives, including private businesses, NGOs, academic institutions, and municipal governments.

Strong Calls for Action at COP30

World leaders emphasized the urgency:

• Mexico emphasized the importance of elevating the ocean in climate policymaking.
• The ocean is the “big blue elephant missing from the climate conversation,” according to Panama.
• Belgium demonstrated that industrial transformations, particularly in offshore wind and green shipping, are aligned with ocean-climate action.

A Shift from Ambition to Delivery

For nations spearheading this agenda, COP30 represents a significant shift from promises to tangible results. The Taskforce will assist countries in modernizing coastal infrastructure, ensuring resilient ocean economies, strengthening blue carbon pathways, and supporting maritime sectors with clean technologies. The France-Brazil partnership supporting this proposal sends a clear message: without ocean leadership, the world cannot meet climate goals while multilateral cooperation is under pressure worldwide.
