Did you know the ocean is the planet’s greatest carbon sink? It absorbs excess heat and energy released from rising greenhouse gas emissions trapped in the Earth’s atmosphere, mitigating the effects of climate change.

​Nature-based solutions in oceans and coastal areas are a vital part of strategies to strengthen livelihoods, ensure food security and protect lives.

UN Climate Change addresses ocean-related climate action under a range of bodies and processes, and in collaboration with other UN agencies and non-party stakeholders.

By collecting climate data and information. This year, countries must submit their first-ever Biennial Transparency Reports (BTRs), assessing the actions they have taken to deliver on their Paris Agreement climate commitments.

Under the enhanced transparency framework, the first BTRs are due by December 2024 and will provide a snapshot of countries' progress in cutting emissions, putting in place climate policies, and providing resources where they're needed. They will highlight existing solutions and inform the next round of national climate plans (NDCs) with even more ambitious targets.

Strong climate reporting provides crucial data and information that help governments make informed decisions, attract climate finance and achieve broader development goals.
