At COP30 in Belém, 17 countriesincluding France, Brazil, Belgium, Canada, and Singaporejoined the Blue NDC Challenge, signalling a global push to integrate ocean-based climate solutions into national climate plans under the Paris Agreement.

What is the Blue NDC Challenge?

• A global voluntary initiative encouraging countries to embed ocean-related mitigation and adaptation actions into their Nationally Determined Contributions (NDCs).
• Seeks to close the “ocean opportunity gap”, as oceansdespite covering ~70% of Earthreceive <1% of global climate finance and are underrepresented in mitigation plans.

Key Features

• Expanded Membership: Coalition now includes 17 countries, with recent entrants such as Belgium, Canada, Indonesia and Singapore.
• Ocean Taskforce: Supported by France and Brazil to assist governments in integrating ocean solutions into updated 2030 NDCs and translating commitments into policy and implementation.
• Blue Package: A coordinated action framework across five Ocean Breakthrough sectors:
  1. Marine conservation
  2. Ocean (aquatic) food systems
  3. Offshore renewable energy
  4. Shipping decarbonisation
  5. Coastal tourism
• Mitigation & Adaptation Focus:Recognises oceans’ potential to deliver up to ~35% of global emission reductions required for the 1.5°C target.
• Blue Carbon Pathways: Integration of mangroves, seagrasses and salt marshes into national mitigation and adaptation strategies.

Why Oceans Matter for Climate Action

• High Mitigation Potential: Offshore renewables, low-carbon shipping, and sustainable fisheries can significantly cut emissions.
• Adaptation & Resilience: Coastal ecosystems protect shorelines, support livelihoods, and enhance food security.
• Underfunded Sector: Ocean-related actions account for <1% of global climate finance, despite large co-benefits.

Global Context

• A growing majority of countries now include ocean priorities in their NDCs, but adaptation dominates, while mitigation commitments remain limited.
• Conservation and blue carbon are most common; shipping decarbonisation, offshore renewables, and low-carbon aquatic food systems are underrepresented.

Significance of the Initiative

• Mainstreams the Ocean–Climate Nexus in national climate policy.
• Mobilises Finance & Technical Support through coordinated action and partnerships.
• Links Climate Action with Development: Job creation, clean energy expansion, biodiversity protection, and coastal community resilience.
• Supports Synergy across global environmental frameworks (climate, biodiversity, sustainable development).
