COP30: Why It Matters for the Ocean (and for Us All) 

This November, the world will meet in Belém, Brazil, for COP30 – the 30th United Nations Climate Change Conference. It’s a milestone moment for global climate action, as countries set new 2035 targets to curb emissions and limit warming to 1.5°C. 

At Live Ocean, we know the ocean is central to that goal. It regulates our climate, absorbs the majority of excess heat and carbon, and supports life on Earth, yet it remains underrepresented in global climate plans. Here in Aotearoa New Zealand, we have responsibility for the fourth largest ocean space on the planet – so we’re not too small to matter.  

As COP30 approaches, we’ll be watching closely because a healthy ocean is one of the most powerful allies we have for a stable climate future.

What is COP30?

COP30 is the 30th “Conference of the Parties”. This major United Nations Climate Change Conference brings together brings together world leaders, governments, NGOs, civil society, and businesses to negotiate and cooperate on climate action. In November 2025, leaders from nearly 200 countries will gather in Belém, Brazil, to assess progress under the Paris Agreement and agree on next steps to limit global warming. 

Why Is This Year’s COP Important?

2025 is a milestone year, marking a critical halfway point to 2030, when countries are expected to meet their climate pledges under the Paris Agreement. For the first time, countries will bring forward their new 2035 climate targets – the next generation of Nationally Determined Contributions (NDCs). These targets will shape how fast the world cuts emissions over the next decade, and whether we can still keep 1.5°C within reach. 

What Does The Ocean Have To Do With Climate Change?

Everything. The ocean absorbs more than 90% of excess heat caused by greenhouse gas emissions and around a quarter of the CO₂ we produce each year. It is the planet’s largest carbon sink and climate regulator – but it’s also under immense pressure from warming, acidification and biodiversity loss. A healthy ocean is essential for a stable climate.

Is The Ocean Part Of The COP Agenda?

Increasingly, yes – but not enough. While recent summits have started to recognise the ocean –climate connection, ocean-based solutions are still missing from many national climate plans. From restoring coastal habitats like mangroves and seagrasses to protecting marine areas that store carbon, there’s huge untapped potential for action.

Why Does This Matter To Live Ocean?

At Live Ocean, we’re driven by the science that shows ocean health and climate stability are inseparable. COP30 is a global moment to spotlight that link, to ensure decision-makers see ocean protection and restoration not as a side issue, but as a core part of climate action. Our work champions and supports the people and projects leading the way in ocean research, restoration and resilience here in New Zealand. Learn more about the projects we support.

What Can We Do From Here in Aotearoa New Zealand?

Stay engaged and informed. Follow credible climate and ocean updates, support initiatives that protect and restore marine environments, and use your voice to call for ambitious climate leadership. 

What’s Next?

We will share updates on key outcomes throughout the event.
