Waves at sea level Thierry Meier

The ocean covers more than 70% of the surface of the planet and holds 97% of all water on Earth. It's impossible to ignore, so how is it being overlooked as critical to fighting the climate crisis?

Why a healthy ocean is vital

We rely on the ocean and the life it contains as our life support system; for every other breath we take, and to absorb and store dangerous greenhouse gases.

When the ocean suffers, so do we.

Marine and coastal environments such as saltmarshes, seagrass meadows and the seabed capture and store huge amounts of carbon (known as blue carbon). But when these habitats are damaged or destroyed they can’t continue to absorb or store carbon, which can then end up back in the atmosphere – contributing to global warming.

An ocean filled with seagrass meadows, kelp forests, animals and more, will absorb carbon much like forests on land and keep it locked in.

The healthier our ocean is, the more it can help fight the climate crisis.

That’s why we want to see the UK Government commit to protecting and rewilding our marine ecosystems in the same way as our woodlands and peatbogs. The ocean is our biggest and best hope at fighting the climate crisis. We must protect it, rewild it and invest in it.

What we're calling for

In order to reach net zero – a key goal for COP26 climate discussions - the quantity of carbon dioxide taken from the atmosphere and stored in natural solutions must increase. By protecting and rewilding ecosystems in our ocean, blue carbon stores will have increased capacity and ability to store carbon.

The ocean can help the UK reach its climate goals.

At COP26, we'll be calling on the UK Government to invest in ocean solutions to fight the climate crisis. That means committing to protecting and rewilding our marine environment.

A healthy ocean will support a healthy planet.

Protection

We need to remove damaging fishing activities like bottom-trawling from at least one third of our seas, to allow the seabed to store carbon and let nature recover. Find out about the current state of the UK’s protected seas on our Marine Protection reality checker map and by downloading our Marine unProtected Areas report.

Rewilding

We must restore habitats like seagrass meadows, salt marshes, shellfish beds and carbon-rich seabed habitats, to increase carbon fixing and storage, help nature recover and protect our coasts from floods and storms.

Investment

The UK Government must scale up climate finance to support ocean- and nature-based solutions, including rewilding projects. You can read more about this in our report – Blue carbon: ocean-based solutions to fighting the climate crisis.

What exactly is COP26?

The UN-led Conference of the Parties (COP) was set up nearly three decades ago to bring all nations of the world together to discuss climate issues.

Since then, climate change has gone from being a fringe concern to an absolute global priority.

When Paris hosted the COP21 in 2015, the momentous Paris Agreement was signed. Every country committed to working together to keep global warming to under 2 degrees, and aim for 1.5 degrees to minimise the devastating effects that climate change is having on our planet.

Climate change has gone from being a fringe concern to an absolute global priority.

World leaders set ambitious targets for reducing their country's emissions, with plans to be reviewed and updated every five years. Now that five years is up, which is why COP26 is such a pivotal summit.

What's on the agenda

In the run up to COP26 (delayed for a year because of the pandemic), countries have been laying out their new climate plans.

To keep the 1.5 degree target within reach, global emissions need to halve by 2030. Many governments, including the UK, have committed to reaching net zero by 2050.

They plan to achieve this by:

  • accelerating the phase-out of coal
  • stopping deforestation
  • speeding up the switch to electric vehicles
  • investing in renewable energy

What’s missing from the UK Government’s plans and promises is, crucially, the ocean. Investing in the protection and rewilding of the ocean would help the UK reach its emissions targets faster, and more effectively, than if we continue to just focus on solutions on land.

We’re delighted to be attending the conference in Glasgow in November, so we can speak up for the ocean and make sure that it becomes part of the UK's climate change solutions.

We’ll be urging the UK Government, and decision makers globally, to wake up and #ListenToTheOcean.
