Our ocean gives us every second breath. It absorbs around a third of the CO2 we pump out, and has taken in over a nuclear bomb’s worth of heat every second for the past 150 years. It underpins our climate system and keeps our planet habitable: It is the blue beating heart of our planet.
Evidence continues to pile up that thriving ocean life is essential for tackling the climate crisis. Yet, when it comes to inclusion in climate policies, marine habitats are often neglected. At the same time, illegal and unsustainable fishing practices are driving the collapse of diverse marine ecosystems across the globe, with devastating consequences for people and for our climate.
We call on national governments to recognise the critical importance of our ocean and blue carbon in the fight against the climate emergency and to take the necessary steps to eradicate illegal and unsustainable fishing to protect marine biodiversity and fisheries in particular.
Protecting our one global ocean
As we face up to global warming, the world must recognise that preserving the vast reservoirs of blue carbon in coastal and marine environments is vital for avoiding catastrophic climate breakdown.
The COP26 climate talks in November 2021 are arguably the most important meeting for generations. They will either set us on the road to a sustainable future for humanity, or towards conflict, suffering and mass extinctions.
EJF calls for world leaders to:
- Recognise the critical importance of our ocean and blue carbon in the fight against the climate emergency.
- Include specific, legally binding targets to protect and restore blue carbon environments in their updated Nationally Determined Contribution implementation plans, under the Paris Agreement.
- Commit to the 30x30 ocean protection plan and designate at least 30% of the ocean – including ecologically representative areas – as fully or highly protected marine protected areas by 2030.
- Implement an international moratorium on deep sea mining to protect the deep sea from irreversible, large-scale harm.
What is blue carbon?
Blue carbon is the carbon captured by the world's ocean and coastal ecosystems. From coastal mangroves to whales at sea, a thriving ocean filled with life captures carbon like no other ecosystem on Earth.
From carbon sink to carbon source
Degradation and destruction of these ecosystems through coastal development, pollution and damaging fishing practices is occurring at a furious rate. Damage to these marine environments reduces their capacity to act as a carbon sink, and increases the release of stored carbon. This results in emissions of CO2, which contribute to the climate crisis.
The current loss of mangroves, salt marshes and seagrass are estimated as among the highest of any ecosystem on Earth. Every half an hour a seagrass meadow the size of a football pitch is destroyed, and the destruction of seagrass is estimated to release around 299 million tonnes of carbon every year. Additionally, the annual loss of all coastal wetlands is estimated to release around 450 million tonnes of carbon.
And it isn't just marine plants we need to cherish. In the last decade scientists have discovered that the so-called "great whales" lock up large amounts of carbon from the atmosphere – up to 30,000 kilos over a lifetime. Some of this sinks to the ocean floor when they die, where it is stored in sediments for vast periods of geological time. Their faeces fertilise the surface waters, feeding microscopic algae called phytoplankton, that produce a vast volume of the oxygen we breathe and absorb billions of tonnes of carbon every year.
Protecting our climate, wildlife and livelihoods
The protection of marine environments is vital in the mitigation of climate change. Preservation of these ecosystems will cut carbon emissions, and their effective management will also promote increased carbon uptake. Sequestering and storing blue carbon demonstrates the opportunities within nature-based solutions to tackle global climate change.
Doing this will not only help us address the climate crisis. It will also help us to protect wildlife and people. Blue carbon protection brings economic benefits and food security by helping maintain healthy fisheries and, with 40% of the global population living within 100 kilometres of the coast, plays a vital role in protecting coastal communities from natural disasters, such as storms and flooding.
These benefits make the protection of blue carbon potentially highly cost effective, with over 20% of the most commercially important fish species occupying seagrass meadows at critical stages of their development. Another vital coastal ecosystem, mangroves, reduce flood damage by up to 29% and provide flood protection benefits estimated to be worth at least 65 billion US$ per year.
Vital part of our climate systems
Coastal wetlands store 3-5 times more carbon per acre than tropical forests and seas. The dense meadows of seagrass that lie in coastal waters around the world not only act as nurseries for vast numbers of species, they also contain up to 18% of oceanic carbon.
Nature’s solution to climate change
Restoring and protecting blue carbon is by no means an excuse for polluters to continue along a ‘business-as-usual’ path. Increased carbon removal from the atmosphere must also be accompanied by a global reduction in human-related carbon emissions.
However, it is clear that these reservoirs of blue carbon are a remarkable gift. Their protection and restoration remain an effective, low-cost, and natural way of mitigating the global climate crisis. Preserving blue carbon avoids the risk of unanticipated harm from untested high-tech climate fixes. It offers opportunities for countries to achieve their emission reduction targets through Nationally Determined Contributions, while also promoting oceanic and biological health.
Mangroves are essential for wildlife and for us all. They store up to four times more CO2 than tropical rainforest by hectare, but they are under threat. It’s time for seaforestation to support these amazing ecosystems.

EJF's Blue Carbon Campaign
Despite their incredible importance, blue carbon ecosystems and wildlife don’t get the recognition or protection they deserve. Whales are still struggling, and mangroves and seagrass meadows are in retreat globally. We want to see thriving wildlife and ecosystems, and a "seaforestation" of the mangroves and seagrass meadows which have been lost.
That’s why we are joining with other NGOs, celebrities and scientific experts to send a clear message to world leaders: protect blue carbon! Our open letter to protect ocean environments will be delivered ahead of the crunch climate talks in Glasgow this year.
