I beg to move,

That this House has considered World Ocean Day.

It is a pleasure to speak under your chairship, Mrs Latham. Our ocean, our largest ecosystem, is a precious natural resource and for too long we have taken it for granted and somewhat abused it. Over and illegal fishing in some parts of the world, pollution, including by chemicals, plastics and nutrients, and overdevelopment along coastlines have all contributed to our ocean not being as healthy as it should be. There is an urgency to tackle global climate change, and given the right focus, support and investment, the ocean is one of our best and most cost-efficient nature-based solutions. As an island nation, our national seas also have huge social and economic value for the UK and especially for our coastal communities. The ocean is our bright blue hope.

Today is the 31st anniversary of World Ocean Day, which gives us the opportunity to highlight and support the implementation of worldwide sustainable development goals and to foster public interest in the protection of the ocean and the sustainable management of its resources. This year it specifically raises awareness and supports the goal and the commitment from global leaders to conserve at least a third of our land, water and ocean by 2030, known as 30x30. It also builds on the high seas treaty agreed in March this year by a number of nations to protect the world’s biodiversity in international waters.

The historic high seas treaty took 10 years of negotiations to reach agreement. It aims to safeguard and recuperate marine nature and provides the ability to more easily realise the target of establishing 30% of the global ocean as marine protected areas by 2030. The treaty also strengthens governance of the world’s ocean by providing the framework to manage the ocean and sustainably use its biological resources. Prior to the treaty, there was no means for nation states to declare marine protected areas beyond their national jurisdiction. The new treaty supports a holistic ocean governance framework as a means to implement the obligations to protect and preserve the marine environment, as included in the United Nations convention on the law of the sea.

That is an important step as the ocean covers 70% of the planet’s surface area and produces around 50% of the oxygen we breathe. It has a hugely significant role to play in slowing down the rate of climate change. Since 1978, more than 90% of the Earth’s increased heat and 40% of carbon emitted from burning fossil fuels have been absorbed by the ocean. Furthermore, it is estimated that the ocean has absorbed between 25% and 30% of all carbon dioxide emissions caused by human activity, making it the largest carbon sink in the world.

The sea is home to most of our biodiversity. According to the United Nations, 3 billion people globally rely on the ocean for their livelihoods, and around 200 million people are employed either directly or indirectly in related industries. However, the UN also states that carbon emissions from human activity are causing ocean warming, acidification and oxygen loss.

A debate about the ocean could cover many topics, including plastic, sewage, chemical or nutrient pollution, marine protected areas, fishing, and renewable energy opportunities and risks. I am sure that some hon. Members will discuss those today. I want to focus on blue carbon and ocean-based solutions to climate change, which, worryingly, are disappearing and require urgent global restoration and protection. We also need to conserve and use ocean resources sustainably, as healthy oceans and seas are essential to human existence and life on Earth. For too long our ocean has been the missing part of our path to net zero. It is essential that Governments across the world take rapid action to increase the ocean’s critical role in tackling climate change.

Our oceans offer significant solutions that can mitigate and combat climate change. It is predicted that blue carbon ecosystems could sequester and store around 2% of UK emissions per year. There is huge potential lying beneath our waters, which have yet to be fully realised.

According to estimates from the Office for National Statistics, the UK’s salt marshes and subtidal muds and sands alone captured at least 10.5 million tonnes of carbon dioxide equivalent in 2018—the real amount could be as much as six times higher. That carbon sequestration, according to the ONS, is of significant economic as well as environmental value—valued at more than what is earned from exploiting our oceans for oil and natural gas.

Let us not forget that our coastal salt marsh areas can help protect against flooding from sea level rise if properly restored, maintained and managed. Seagrass meadows provide among the most productive ecosystems in the world. An area the size of a football pitch can support more than 50,000 fish and more than 700,000 invertebrates, which is good news for our marine habitats and fishing communities around the UK. One acre of seagrass can sequester 740 lb of carbon per year, or 83 grams of carbon per square metre, which is the same amount emitted by a car travelling 3,860 miles.

[Theresa Villiers (Chipping Barnet) (Con)]

Does my hon. Friend agree that there is not enough understanding of how important blue carbon is or of the crucial role that the ocean could play in absorbing and capturing carbon? It is, therefore, great that we have the opportunity to debate it today.

[Sally-Ann Hart]

Yes, I completely agree with my right hon. Friend. One issue is that we do not yet have enough data and research to truly evaluate the amazing role that blue carbon can play.

UK coastal habitats such as seagrass and salt marsh provide an estimated £48 billion of economic benefits to society, despite occupying only 0.6% of the total land area. Based on available data, the Office for National Statistics values the UK’s marine natural capital assets at £211 billion, so protecting and restoring the UK’s marine natural capital assets preserves more than the environment. It has value for people and the economy.

Maintaining and, more importantly, restoring and improving marine ecosystems to sequester carbon is vital in mitigating climate change. Fully restored, our coastal ecosystems could capture emissions equivalent to one third of the UK’s 2028 emissions and save an estimated £6.2 billion in spending on artificial flood defences by 2050. It is essential that the UK Government take further measures that protect and restore our marine areas, ensure greater research and provide more sustainable funding for all types of blue carbon and carbon dioxide removal. But no Government can fund entirely the actions needed to unleash the full power of nature. They need to look carefully at how they can encourage and facilitate private sector funding.

There are new fledgling organisations such as the social enterprise Bright Tide, which was founded by Harry Wright. Bright Tide is doing a sterling job in working with businesses to address urgent climate and biodiversity challenges around the world. I ask the Minister to outline what the Government are doing to recognise and facilitate funding to protect ocean nature-based solutions.

Also, will the Minister update the House on the measures that the Department for Environment, Food and Rural Affairs has taken to ensure that blue carbon habitats are restored, increased and properly protected? Our ocean is incredibly important to coastal communities such as mine—beautiful Hastings and Rye—because many livelihoods, from fishermen and tourism to aquaculture and renewable energy, depend on a healthy, clean and functional coastal environment to ensure long-living and sustainable industries. Without careful planning and review of impacts from human activities, both the environment and livelihoods are at risk.

I chair the all-party parliamentary group on coastal communities and the all-party parliamentary group for the ocean. Coastal communities and our national seas are interlinked—co-dependent. The APPG for the ocean’s first inquiry, into blue carbon and ocean-based solutions to climate change, produced an excellent and comprehensive report, “The Ocean: Turning the Tide on Climate Change”, and three of our eight recommendations were echoed in the Government’s recent environment improvement plan. They include our recommendations to remove trawl or dredge zones, which can destroy marine ecosystems and disturb seabed carbon stores, from UK MPAs; create highly protected marine areas; and include more aspects of marine carbon storage and sequestration, specifically seagrass and salt marsh habitats, in the UK greenhouse gas inventory.

Our report also highlighted that investing in coastal and ocean-based solutions can considerably boost industry and the economy in coastal areas. As an MP for a coastal community and as chair of the APPG on coastal communities, I recognise at first hand the solutions that the ocean can offer in mitigating and combating climate change. I also recognise the added value, huge benefits and potential that ocean-based solutions can have for coastal communities in creating new skills and jobs in tourism, ecotourism, seabed mapping activity, the renewable energy industry, environment and ecology, aquaculture, fishing and so on. Nature is the most cost-effective solution in combating climate change, as well as providing added value. We must unleash her power.

The report also highlighted that blue carbon and ocean-based solutions are often neglected in conversations about climate change, despite the fact that the destruction of marine habitats such as seagrass—the wonder grass—may be of greater consequence than land-based destruction such as deforestation. Why are they overlooked? Part of the reason is the lack of understanding, research and data. Certain types of ocean-based solutions, such as those that could occur in the open ocean or seabed, are even less understood and require greater mapping to understand the clear benefits. It is time to review our ocean, not only as something that needs protecting, but as a useful tool—a living, breathing organism that can help us tackle climate change.

Finally, with the increasingly diverse uses and potential uses of the ocean and the growth in areas designated for marine conservation, there are clearly growing spatial pressures on our ocean—spatial squeeze. That may have an effect on our more traditional industries, such as our fishing fleets. I know that the fishermen of Hastings and Rye are concerned about that. We must ensure that offshore renewables—windfarms and tidal stream energy for example—blue carbon habitats, marine protected areas, fishing grounds, aquaculture, cables, oil and gas all coexist, where possible, so that there is space for all without detriment to traditional industries such as fishing or to the marine environment. There is an argument to be explored for a new approach to marine spatial planning that involves the co-management of our national seas and greater accountability for regulators. I would be keen to hear the Minister’s thoughts on that.

By protecting, researching and investing in ocean-based solutions and blue carbon habitats, the UK can ensure that our net zero targets are met, that coastal communities can benefit from significant opportunities and that the ocean becomes an active player in climate change mitigation. We all need to work together to ensure that that happens.

[Theresa Villiers (Chipping Barnet) (Con)]

It is a great pleasure to serve under your chairmanship, Mrs Latham. I warmly thank and congratulate my hon. Friend the Member for Hastings and Rye (Sally-Ann Hart) on securing this debate on World Ocean Day. She is a great champion of coastal communities in general and Hastings and Rye in particular.

As we have heard, the ocean covers 70% of the Earth’s surface and is the largest carbon sink on the planet. To take just one example, salt marsh and seagrass habitats can store and hold massive amounts of carbon for thousands of years, so there is huge potential for ocean-based solutions—so-called blue carbon—to play a key role in delivering net zero and protecting the climate from disaster. At the same time, well-managed blue carbon projects can help deliver levelling up through the creation of new high-paying, high-quality jobs in coastal communities.

The massive potential of blue carbon was highlighted in the report, “The Ocean: Turning the Tide on Climate Change”, published last year by the APPG for the ocean, of which I am a member. In it, we pointed out that we cannot hope to succeed in our ambitions on combating climate change without using ocean and land-based carbon removal solutions, so we need better mapping of the blue carbon habitat within the UK’s exclusive economic zone. We also need more research, more data and a better understanding of the capacity of the marine environment to absorb and store carbon. That goes beyond salt marshes and seagrass to include ideas such as seaweed cultivation and ocean alkalinity enhancement.

To harness the potential of blue carbon, it is vital that we do more to protect the marine environment and the biodiversity it contains. That brings me to plastic. Plastic pollution is one of the great tragedies of our time. Plastic is a versatile material that has many benefits, but we must find a way to reduce its use, recycle more of it and, above all, ensure it is disposed of responsibly. It is shocking that, less than a century after its invention, such a vast volume of plastic has made its way into every corner of the ocean. I feel genuinely disturbed when I see pictures of the impact that it has on wildlife, including of young birds that perish because they are fed plastic by their parents, which mistake it for food. We have to do something about the situation. I know the Government are taking a strong, leading role in tackling the scourge of plastics pollution and have passed some of the world’s first laws against microbeads in personal care products, which was a big step forward.

I also welcome the fact that the Government pioneered the Commonwealth Clean Ocean Alliance to seek the international action that is so crucial. They are also leading the Global Ocean Alliance to meaningfully protect 30% of land and sea by 2030, but there is a vast amount of work that still has to be done. For example, we need to consider how to reduce the flow into the sea of microfibres from clothing. In that regard, I commend the campaign led by my hon. Friend the Member for South Leicestershire (Alberto Costa), the National Federation of Women’s Institutes and the Marine Conservation Society for filters that catch such fibres to become mandatory in new washing machines sold from 2025.

Let us also see the delivery of the Government’s long-promised extended producer responsibility and deposit return schemes to promote plastic recycling, reuse and responsible disposal. I have mentioned that to the Minister many times; she knows my views. I hope that the frankly chaotic situation with the Scottish National party version of DRS will not jeopardise getting a workable scheme in place across the whole of the UK.

Above all, we must have more concerted action globally if we are to tackle the problem of plastics pollution in the ocean effectively. Progress on that is being made, too: the draft high seas treaty agreed in March signals a real intent to ensure that human activities in the high seas are consistent with conservation objectives. I urge the Government to engage energetically in securing the international treaty on plastics that is vital in driving forward the rescuing of our oceans.

In conclusion, we have a responsibility to act against plastic pollution and the destruction of precious ocean habitats. Together with our overseas territories, we are stewards of one of the world’s largest marine estates. This nation built a vast empire largely because we had the most powerful Navy on the planet, which has protected our shores and our freedom ever since it was founded by Alfred the Great over 1,000 years ago. Our continuing links with the overseas territories are one of the last legacies of that once-mighty empire, so let us use those ties of friendship and history to work with overseas territories to push forward with further protection for the seas and oceans that have played such a seminal part in our island’s story. It is essential that we safeguard them for the future.

[Chris Grayling (Epsom and Ewell) (Con)]

It is a great pleasure to serve under your chairmanship, Mrs Latham. I echo the words of congratulation of my right hon. Friend the Member for Chipping Barnet (Theresa Villiers) to my hon. Friend the Member for Hastings and Rye (Sally-Ann Hart) on securing this debate. This issue is enormously important, and does not get enough time in this House. Even as the co-chair of the all-party parliamentary group on global deforestation, I find that we are too apt to look at what happens on land, and not apt enough to look at what happens at sea. This is a very appropriate and topical debate, particularly on World Ocean Day, as my hon. Friend said.

I am pleased to see the progress that has been made in recent months, including the treaty that was agreed back in March and the output of the various conferences of the parties of the past 18 months. I hope that the next COP, due to take place in the United Arab Emirates this autumn, will drive improvements to our approach to tackling biodiversity loss. I equally hope that it will reflect the need to protect ocean biodiversity.

I will focus on three aspects of the challenge we face: the need to protect more, the need to restore more, and the need to enforce more. Let me start with protection. The Minister knows of my concern to ensure that we accelerate our work on marine protected areas and highly protected marine areas; we debated that in this Chamber only recently. That is fundamentally important both for our nation and for the globe, because protected areas are about not just the UK but important areas of marine ecology around the world.

But let us start at home. We are making progress. The work that the Government have done on Dogger Bank and in other areas is very welcome, as is their ambition. As the Minister knows, my only concern is the pace. We need to do more, because although we have marine protected areas, most people would judge them not to be particularly well protected at all. In those areas, we still allow large industrial trawlers to scan the seabed with huge mechanical equipment, causing all kinds of damage and destruction. That may be appropriate in some parts of the sea, but it is inappropriate in our marine protected areas. It is particularly important that we accelerate the process that has started. As we have left the common fisheries policy, we have the freedom to apply proper protections. We will renegotiate our fishing arrangements with the European Union in the next couple of years. I suspect that those in Brussels are probably expecting things to carry on much as they are. We must ensure that is not the case, and that we really do take a significant step forward in applying UK-focused and ecology-focused rules to our fisheries, particularly those that are in need of much greater protection.

There is also the issue of the highly protected marine areas, which are much smaller. A substantial part of the seas around the United Kingdom are covered by our protected marine areas. The highly protected marine areas are much smaller, which is as it should be, because very little fishing should take place there at all. They need to expand too, and the Benyon review was very constructive in that respect. Of course, Lord Benyon is now very much at the heart of delivering this.

We must not make the same mistake as Scotland, which pressed ahead without engaging and involving the fishing communities. I take the view that the fishing communities of this country benefit from measures that look after our marine life and particularly our fisheries, because without those, the fishing communities have no livelihood. I do not think that our fishing fleets in the UK have anything to fear from a more robust approach to marine protection, because they see their fisheries disappear when we have huge industrial boats scouring the ocean in areas where we should be restoring fish stocks, not allowing them deteriorate still further. The benefit of highly protected marine areas, where there is virtually no take at all, is that they really do give the fish and the other life a chance to recover. In fact, fish stocks in areas around the most protected areas, where there is genuine enforcement, are now better as a result, and fishing fleets benefit from that.

I will continue to push the Minister, who I know is very sympathetic on this issue, and, through her, her officials to get on with this. They have made a good start, but I still see no reason why we cannot deliver a complete ban on bottom trawling in marine protected areas and deliver a significant increase in the area covered by highly protected areas in the time left in this Parliament. Our fishing communities and our ecology would benefit greatly if we did.

My hon. Friend the Member for Hastings and Rye mentioned the 2030 goals—the 30x30 protections. We have to play our part in ensuring that other countries do the same as us, and help them where they need political, financial or other support to do so. It is all well and good the UK protecting our waters, but if others do not do the same, we clearly do not achieve anything like what we need to achieve globally. Our ocean is a global asset. We have to protect it. We need to support other countries in enforcing proper protections in their marine protected areas, and in banning the most damaging fishing practices in those areas, so that see the ecology recovers.

This does work. When we put in place greater protections, numbers rise. We need only look at the whale population. Whales were in serious danger of extinction, but since positive steps were taken globally to ban whaling, numbers have started to surge. People can go and see these magnificent creatures all around the world now. If we take similar steps to provide appropriate protections in key areas of marine ecology—I am talking about excluding fishing, not from whole seas, but in key areas—we will benefit enormously. I am thinking of areas such as Galapagos, where until recently there was a genuine threat from some of the big, global fishing fleets that were sailing around the Pacific. We need to ensure that absolute, proper protection is in place, backed by enforcement; I will come back to enforcement in a moment. This is not just about protection of what is there; it is also about restoration of habitats that have been lost. My hon. Friend the Member for Hastings and Rye and my right hon. Friend the Member for Chipping Barnet are absolutely right: there are opportunities to recreate habitats in the ocean, which can make a real difference to supporting and restoring marine life.

My hon. Friend the Member for Hastings and Rye mentioned seagrass. There is clearly an opportunity for us in the United Kingdom on that. There are interesting projects taking place around the UK to begin to restore some of the seagrass that has been lost. We have lost something like 90% of our seagrass beds. We need to restore those, and we need to create the space for that to happen, because that helps marine species to recover. I would also mention kelp. If she has seen the extraordinary photography in the recent BBC “Wild Isles” series, she will have seen just how extraordinary kelp forests around the UK are. They, too, have disappeared to much too great an extent. We need to reverse that.

This does not really apply to our shores, but we must also focus on mangroves, because mangroves in coastal waters around the world have disappeared at an alarming rate, and they play a hugely important part both in the ecology of coastal areas and in protecting local communities against rising sea levels, floods, storm tides and the rest. I would therefore like—this does not fall within the Minister’s Department; it falls more to the Foreign, Commonwealth and Development Office—those elements of our aid budget that go on supporting ecological projects to support the restoration of mangroves around the world. Of course, there are big, global efforts taking place to do that, and to restore other marine habitats.

One of the most extraordinary projects I have come across in the last couple of years is the work being done by Mars Sustainable Solutions, and community groups working with it around the world, to restore coral reefs. The before and after for such projects is quite extraordinary. If a simple piece of netting, which looks like the inside of a chip pan, is placed on the seabed near a reef that has deteriorated, the reef regrows quickly, so there is a real opportunity to restore some of what has been lost.

Too many of our reefs are in danger, and too many have suffered damage from changes to water temperature, boats and the impact of mankind, but it is possible to restore reefs more quickly than one might imagine. Across the piece, we have an opportunity. Replanting seagrass, supporting the regrowth of kelp, and restoring coral reefs and mangroves can all play a part in capturing carbon, helping to restore local habitats and making the ocean healthier, so we as a nation should be putting as much effort as we can into helping the restoration of those habitats around the world. As I say, I speak as somebody who campaigns on deforestation and, indeed, on reforestation, but we must not forget marine environments.

Then we come to the issue of enforcement, because all our efforts are pointless if illegal operations destroy marine habitats again. Along with the treaties that have been agreed over the last 18 months, the good work being done on restoration, and what I hope our Government and others will do to put in place proper protections in marine protected areas, we also need really robust enforcement, because we have too many illegal and unregulated fishing operations doing real damage to fish stocks and marine environments around the world. Often they are carried out by vessels that simply go dark. Law-abiding, decent fishing vessels go around and do their stuff with proper tracking systems onboard, so we know where they are. If I opened up an app on my phone, I could probably see where most of the vessels are. Those that do not play within the rules disappear—they go black. That cannot be tolerated, because then however many rules we put in place, damage is still being done.

We as a country need to play our part as we move to the next stage in the negotiation of global agreements. We have done some really good work in putting together frameworks for the future, but they now need to be translated into action if we are to deliver the protections and the constructive approach that have been agreed by countries around the world. However, in order to do that, there has to be proper enforcement of what is put in place. My message to the Minister is this: when it comes to illegal and unregulated fishing, we need to make sure as a nation that we take a lead in saying that the next step is not just practical ecological measures, but the enforcement to go alongside them.

There are tools that we can use. The amount of Earth observation data is now substantial—we have satellite data for even relatively small areas. Supermarkets use Earth observation data to make sure that the products they source do not come from areas of land that have been deforested, which is great. In this country, that is being driven by our pathfinding legislation, the Environment Act 2021. We have a bit more to do, as the Minister and I discuss regularly, and I will happily help push other Departments to work with her to deliver that. But that is on land, and we need to do the same in the oceans. The technology can also be used by supermarkets to look at the origin of the fish stocks they are purchasing. It can also be used by enforcement authorities to look at what is happening—who is fishing where, and who is doing what where—and to take the appropriate action. We can also support countries that do not share our economic strength or ability to take enforcement action; that piece is enormously important. It must be a central part of what we as a nation do, going into the next stage of the various COPs and international discussions about how we turn the 2030 agreements into action. We must provide proper protection, both for restoration work and for what we have at the moment.

Those are the challenges. None of them will be easy, but they are challenges that we have to meet. As a global community, we cannot see the ocean continue to deteriorate and decline. My right hon. Friend the Member for Chipping Barnet is absolutely right about plastic. I happen to believe that before too long, we will end up harvesting it from the oceans. The plastic needs to be removed, but we may well find that it has positive uses, now that technology is moving on, in helping us to combat climate change through a move away from conventional fuels, for example. We may well end up having a positive reason to take that plastic out of the ocean, but we should certainly stop putting it in. We should be taking all the steps that we can to avoid the further pollution of the ocean and further degradation of marine habitats.

We have the foundations and frameworks in place for the next 10 years. They are already agreed in principle, and they now need to turn into action. That action is about protecting what we have, restoring what we lost and enforcing good behaviour to ensure that rogue elements do not get away with doing further damage to our marine habitats. That is not a small task, but I am delighted that we have this Minister in place, because she is very committed to this issue. I congratulate my hon. Friend the Member for Hastings and Rye on calling for this debate. World Ocean Day is a moment for all of us to think about what else we can do, individually and collectively, to protect our oceans.

[Patricia Gibson (North Ayrshire and Arran) (SNP)]

I echo the congratulations to the hon. Member for Hastings and Rye (Sally-Ann Hart) on bringing forward this important debate. It has become something of an annual event to have a debate that coincides with World Ocean Day on 8 June, and it follows, as we have heard, from a recent debate on the impact of plastic in our oceans.

This year’s theme is “Planet Ocean: Tides are Changing”. The tides may well be changing, because experts warn us that we are reaching a tipping point that will bring devastating and dramatic consequences for mankind with regards to our oceans. The purpose of World Ocean Day is

“to inform the public of the impact of human actions on the ocean, develop a worldwide movement of citizens for the ocean, and mobilize and unite the world’s population on a project for the sustainable management of the world’s oceans.”

This day reminds us all of the major role that oceans play in our everyday lives. They are the lungs of our planet, a major source of food and medicine, and a critical part of our biosphere. The ocean covers the majority of the Earth, but only a small portion of its waters have actually been explored. Despite humanity’s utter reliance on it, and compared to the breadth and depth of what it gives us, the ocean receives only a fragment of our attention and resources in return. That surely has to change.

The latest estimates from the UN Educational, Scientific and Cultural Organisation warn that more than half of the world’s marine species may stand on the brink of extinction by 2100. Temperatures have increased by 1.1°C, and an estimated 60% of the world’s marine ecosystems have already been degraded or are being used unsustainably. Warming of 1.5°C threatens to destroy 70% to 90% of coral reefs, and a 2°C increase means a near 100% loss—a point of no return.

The ocean occupies over 70% of the planet’s surface area and produces at least 50% of the world’s oxygen. It is a hugely significant force in mitigating climate change. Despite that, its role is most often considered as passive rather than active, but it has a significant role to play in slowing down the rate of climate change. Since 1978, over 90% of Earth’s increased heat and 40% of carbon from fossil fuels have been absorbed by the ocean. In addition, it is predicted that the ocean has absorbed between 30% and 50% of all carbon dioxide emissions caused by human activity, which makes it the biggest carbon sink in the world, as we have heard today.

I want to talk about ocean acidification. When CO₂ dissolves in sea water, the water becomes more acidic. The acidity of our oceans has increased by 26% since about 1850, and staggeringly, the pace of change is around 10 times faster than at any time in the last 155 million years.

Ocean acidification reduces the amount of carbonate, which is a key building block in sea water. That makes it more difficult for marine organisms such as coral and some plankton to form their shells and skeletons and existing shells may begin to dissolve. The present-day pH of sea water is highly variable and a single organism can cope with fluctuations of different pH levels during its lifetime. The problem with ocean acidification is the sustained nature of the change, as the risk comes with the lifetime exposure to lower pH levels. Further, the rapid pace of acidification will influence the extent to which calcifying organisms will be able to adapt.

The impact of ocean acidification is not uniform across all species, but a more acidic environment will harm marine species such as molluscs, corals and some other varieties. Marine organisms could also experience changes in growth, development, abundance and survival in response to ocean acidification. Most species seem to be more vulnerable in the early stages of life. Juvenile fish, for example, may have trouble locating a suitable habitat. Research suggests that ocean acidification will also be a driver for substantial changes in ocean ecosystems this century. Those changes may be made worse by the combined effects of other emerging climate-related hazards, such as the decrease in ocean oxygen levels—a condition known as ocean deoxygenation—which is already affecting marine life in some regions. Ocean acidification also has the potential to affect food security, coastal protection, tourism, carbon storage and climate regulation because more acidic oceans are less effective in moderating climate change. To reduce the impact of ocean acidification, we need to improve our air quality, develop sustainable fisheries management practices and sustainably manage habitats, as well as establishing and maintaining marine protected areas, about which we have heard a lot today. Currently, only around 8% of our oceans are protected. We need to do more, but on a global and international basis.

A recent YouGov survey of 1,696 adults found that almost three quarters of people in the UK say ocean life needs more protection. At this juncture, I wish to pay tribute to Sir David Attenborough, whose “Blue Planet” programmes brought the ocean world into our living rooms and showed us the wonders and the beauty of our oceans in such an educational and breathtaking way. He also warned us that the living world cannot operate without a healthy ocean—nor can we. The ocean may connect, sustain and support us all, but, according to the UN,

“its health is at a tipping point and so is the well-being of all that depends on it.”

The UN hopes World Ocean Day will help inform the public of human actions on the ocean and develop a worldwide movement to protect it and unite the world in seeking to sustainably manage our oceans, making this is an important day on the global calendar.

I will end with the wise words of Sir David Attenborough:

“Nowhere is more powerful and unforgiving, yet more beautiful and endlessly fascinating than the ocean.”

It is time we act globally in a way that shows we understand how important our oceans are and stop taking them for granted.

[Alex Sobel (Leeds North West) (Lab/Co-op)]

It is an honour to serve under your chairship, Mrs Latham. I thank the hon. Member for Hastings and Rye (Sally-Ann Hart) for securing this important debate. She and all speakers covered the issues comprehensively and laid out a number of solutions and actions that we would like to see taken forward. There is probably an element of unanimity in the debate around what needs to be done.

On World Ocean Day, we acknowledge this year’s theme of “Planet Ocean: tides are changing” as a call to intensify our efforts to understand, preserve and harness the power of our oceans. Our vast oceans hold the key to so much: biodiversity, marine ecosystems, climate change mitigation, food security, renewable energy and the future preservation of our planet. The role of our oceans in combating climate change is grossly underappreciated. More 70% of our planet’s surface is made up of ocean, which produces at least half of our world’s oxygen. Since 1978, the ocean has absorbed more 90% of the Earth’s increased heat and 40% of fossil fuel emissions, making it the world’s largest carbon sink. However, these watery giants are seldom acknowledged as active players in the fight against climate change. We need to draw focus to the power of blue carbon habitats, such as saltmarshes, seagrass meadows and mangroves. We heard extensively from other speakers on those issues.

Our seas and oceans are a rich source of biodiversity. Healthy sea beds are home to many species and drive richer marine ecosystems. Our marine environment and the creatures that call it home face numerous threats from human activity, such as damage from waste and toxins, dredging and dragging of the sea bed, and the destruction of corals, maerls and sandbanks—I could go on.

The Government’s commitment to the UN’s pledge to protect 30% of land and sea by 2030 is all well and good, but their actions do not suggest that they will get us there. The latest analysis from the Wildlife and Countryside Link—the largest environment and wildlife coalition in England—found that although 40% of English waters are designated as marine protected areas, only a maximum of 8% of English seas are effectively protected for nature. While the three new protected marine areas announced by DEFRA this year are welcome, we should note that those sites represent not even 0.5% of English seas.

The impact of humankind on our oceans cannot be understated. It has now been five years since David Attenborough’s groundbreaking “Blue Planet II” forced marine plastic pollution into the public consciousness and inspired millions across the globe to take action. His work encouraged a seismic shift in the public consciousness and helped to put plastic pollution on the political agenda. Despite that, the plastic pollution problem in our oceans continues to get worse. The UN estimates that plastic pollution in oceans and other bodies of water could more than double by 2030. Plastics pose a significant threat to the stability of our global ecosystems and human health, as evidenced by the discovery of microplastics in both seabird eggs and human blood.

It is a global crisis, and we are not exempt from responsibility. In the UK, around 14 billion plastic bottles, 9 billion aluminium and steel cans and 1.5 billion glass bottles are consumed each year. In fact, 75% of the litter found on our streets comprises drinks containers, and much of it finds its way into our waterways. Despite that, the Government’s proposed deposit return scheme is limited to certain materials, rather than creating a framework that could include more types of plastic or bioplastics in the future. Their plan to eliminate all avoidable plastic waste by 2042 is years behind schedule. Only a Labour Government will tackle waste, improve recycling rates and introduce an all-in deposit return scheme to tackle the problem head on.

Our seas are also of huge economic significance, supporting many British people through fishing, offshore energy, building, and tourism—I could go on. The Government’s lack of action is a huge threat to many of those jobs. Consider the worrying 44% drop in the levels of shellfish caught and landed in the UK in just the last year. In Teesside, the local fishing industry has reported a 95% drop in their catches of shellfish, such as lobsters and crabs. Such die-offs are devastating to nature and the fishing sector. However, when the shadow Secretary of State, my hon. Friend the Member for Oldham West and Royton (Jim McMahon), addressed the House on 30 March and asked the Environment Secretary to join him in meeting the North East Fishing Collective, she responded with uncharacteristic clarity:

“I do not need to meet with them,”. —[Official Report, 30 March 2023; Vol. 730, c. 1132.]

So uncaring and callous is the Secretary of State’s attitude to our own waters and biodiversity, we can only assume she has less care for our global oceans. Talking of global oceans, let us not forget that UK overseas territories account for the fifth largest marine estate in the world. I praise Government Ministers, especially Lord Goldsmith, for the blue belt programme and Darwin initiative funding. When I spoke to many of the overseas territories in May at the UKOT conference in Westminster, they still felt that the UK did not give them a voice at global negotiations. That approach would change under Labour, as we would adopt a modern, respectful and engaged partnership with our overseas territories.

It is that sort of attitude that encapsulates how little the Government care about the impact of their actions on the livelihoods of the people they are elected to serve. The tourism industry, for example, has pleaded with the Government to help it stop sewage being dumped into waters near our beautiful beaches. Last month, nine UK beaches lost their blue flag status, including the iconic Brighton beach, which was subject to 45 sewage discharges last year. Just last month, the Government blocked Labour’s Bill that would have ended the sewage scandal and finally have made water bosses accountable.

Our coastal communities should not have to worry about water companies using their water as open sewers while the Government turn a blind eye. While it is positive to see World Ocean Day being celebrated in this way, it is now incumbent on the Government to convert warm words into concrete action and protect our blue planet.

[The Parliamentary Under-Secretary of State for Environment, Food and Rural Affairs (Trudy Harrison)]

It is a pleasure to serve under your chairmanship again, Mrs Latham—two days in a row—especially for such an important debate. I have enjoyed hearing the knowledge and passion of colleagues this afternoon. It is clear that all colleagues present today recognise the importance of our ocean and the urgency with which we need to take action, and with which we are taking action. I am particularly grateful to my hon. Friend the Member for Hastings and Rye (Sally-Ann Hart) for securing the debate, which was perfectly timed, given that today is the UN’s World Ocean Day, the theme of which, as has already been said, is “Protect 30x30”, aimed at protecting at least 30% of our blue planet by 2030.

Despite the official title of UN World Oceans Day—of course, there are many different oceans—I will refer to it as World Ocean Day, because it is one ocean, all connected. The nature and species that survive, thrive and depend on our ocean see no boundaries. There is one global connected ocean, and it makes sense to design policy responses accordingly. There have been many calls this afternoon for us to work collaboratively with devolved Administrations and internationally with other countries. I will come on to the progress that has been made.

Marine life is important. A safe, healthy ocean underpins our lives and our economies and my hon. Friend the Member for Hastings and Rye was correct to say that more must be done. More is being done, but it will not be easy. We have to tackle the triple planetary crises of biodiversity loss, climate change and pollution. Without action, plastic pollution entering the ocean is set to triple by 2040. Over 1 million species, including 33% of reef-forming corals and one third of marine mammals, are predicted to disappear entirely over our lifetimes. Meanwhile, 33% of our global fish stocks are over-exploited.

I want to pay tribute and give thanks to my right hon. Friend the Member for Chipping Barnet (Theresa Villiers) for the sterling work that she did in my Department, setting the scene and paving the way for the Environment Act 2021, off the back of which we have the recently launched environmental improvement plan 2023, which goes into far more detail than I can possibly give here today. It is not just about oceans, but about all aspects of how we will protect our planet and halt the decline of nature by 2030.

We know that many small island—or, more appropriately, big ocean—developing states are bearing the brunt of the challenges from climate change and plastic pollution. They have been raising the alarm for decades while contributing little to the problem. Here in the UK we are seeing the effects, including estimated losses of 85% of our saltmarsh and 92% of our seagrass habitats in the last 100 years.

I also want to thank the hon. Member for North Ayrshire and Arran (Patricia Gibson) for a most insightful and interesting contribution and making us all more aware of ocean acidification. I found her contribution staggering in terms of the acceleration that our oceans are enduring.

But we can be proud of the Government’s record. I was pleased to hear the hon. Member for Leeds North West (Alex Sobel) commend the work of Lord Goldsmith, who attended the APPG for the ocean’s annual general meeting earlier this week, which my hon. Friend the Member for Hastings and Rye also attended. The work is cross-Government. I am also proud of the UK’s international leadership, where we have been at the forefront of securing critically important international agreements. Just last week the Under-Secretary of State for Environment, Food and Rural Affairs, my hon. Friend the Member for Taunton Deane (Rebecca Pow), was involved in the second intergovernmental negotiating committee on plastic pollution, demonstrating that we continue to work with other countries. At the UN biodiversity summit in December, as leader of the Global Ocean Alliance and ocean co-chair of the High Ambition Coalition for Nature and People, the UK helped to deliver a landmark global deal for nature.

The Kunming-Montreal global biodiversity framework commits to halting and reversing biodiversity loss by 2030, including through the 30x30 target for land and the ocean. The Secretary of State attended that conference, which made such fantastic progress, along with my noble Friend Lord Benyon, who is the Minister with responsibility for oceans. There can be no better parliamentary champion for mangroves than the Secretary of State, although his passion is matched by my right hon. Friend the Member for Epsom and Ewell (Chris Grayling), who is a fantastic champion for all things environment and nature. Once again, I heard his plea loud and clear to chivvy along officials in DEFRA, but I think we are making tremendous progress. These things are not easy, but I will support our teams and all the NGOs and devolved Administrations we work with in going as fast as we can, because we understand the urgency. I welcome the constant nudging and encouragement from him on this and other matters.

The UK was also instrumental in agreeing the draft text of the “biodiversity beyond national jurisdiction” agreement earlier this year, which will provide the framework to implement greater protection and governance for over 60% of the global ocean. This is vital to achieving the global 30x30 target.

We also know that biodiversity loss and climate change are inextricably linked. With a 2° rise in global temperature, a predicted 90% of coral reefs will be lost, so we continue to work to raise ambition on ocean-climate action across the United Nations framework convention on climate change, to fill key evidence gaps and to build capacity around the world to protect and restore blue carbon habitats. I hope my hon. Friend the Member for Hastings and Rye will recognise the work that is being done. She called for more research and development, and for better understanding, which is what we are working towards.

As a founding member of the High Ambition Coalition to End Plastic Pollution, which now numbers well over 50 countries, we are pushing for an effective and ambitious plastic pollution treaty that will end plastic pollution by 2040. As I mentioned, the Under-Secretary of State for Environment, Food and Rural Affairs, my hon. Friend the Member for Taunton Deane, was in Paris last week, and I am pleased that the critical decision was made to start drafting the new treaty text, with our world-leading scientists, businesses and NGOs working towards an agreement by the end of 2024.

Alongside protection, we know we have to manage our global ocean sustainably. That is why, last year, the UK joined other ambitious ocean leaders as part of the High-Level Panel for a Sustainable Ocean Economy, again working and collaborating internationally, and it is why we pushed for the June 2022 WTO fisheries subsidies agreement to curtail harmful subsidies and tackle one of the key drivers of overfishing.

In parallel, we are determined to end illegal, unreported and unregulated fishing. I was pleased to speak at a recent debate secured by my right hon. Friend the Member for Epsom and Ewell on this subject. With expanding membership, the IUU Fishing Action Alliance will bring further international pressure and action to stamp out this harmful practice.

Effective ocean action is possible only with the right resources and tools to deliver it. SDG 14, “life below water,” is the least funded of all the sustainable development goals, so the UK is helping to mobilise finance for ocean action. I was particularly pleased to hear my hon. Friend the Member for Hastings and Rye reference the importance of private finance because, of course, taxpayers’ money can go only so far. My noble Friend Lord Benyon, as the Minister with responsibility for green finance, is working diligently and determinedly to secure that private finance, particularly for the oceans. The UK’s blue belt programme is supporting the British overseas territories. It is so important that we work with our overseas territories to take action to protect the ocean. With £30 million of support since 2016, the blue belt now protects 4.3 million sq km of ocean and supports sustainable growth.

Our £500 million blue planet fund is supporting developing countries to address biodiversity loss and climate change by tackling marine pollution and supporting sustainable seafood in some of the world’s most important but fragile ocean environments. Just this morning, Lord Benyon hosted a roundtable to understand how public and private sector investment can come together to deliver a blended finance solution through the excellent global fund for coral reefs programme, which supports the ocean, reefs and climate-vulnerable communities.

But, of course, our action starts at home. We remain committed to achieving a good environmental status in our seas, and we will shortly publish an update to our programme of measures to do so. We have already built a comprehensive network of marine protected areas— 374 sites covering 38% of the UK’s waters and 40% of England’s—and we are focused on making sure that they are properly protected. Nearly 60% of England’s inshore MPAs now have fisheries byelaws in place. Having left the EU, we can put in place management to protect against damaging fishing practices in our offshore sites. The first four byelaws for offshore sites were made last year, and we plan to finish putting in the management needed in all MPAs by the end of next year.

Using the new powers in the Environment Act 2021, we now have a statutory target to make sure our MPAs are recovering our biodiversity. We have announced the first three highly protected marine areas, which provide the highest levels of protection. Those sites will be designated in the next month, and we are starting to look at further sites.

Protecting and restoring critical blue carbon habitats is a key part of our approach to protecting coastal communities, such as the one I live in, from rising seas and more frequent storms. That will deliver biodiversity and absorb carbon dioxide.

I am delighted that the cross-Administration UK Blue Carbon Evidence Partnership is publishing its evidence needs statement today, setting out key research questions and demonstrating the UK’s ambition to fill critical blue carbon evidence gaps. In response to the UN decade of ocean science for sustainable development, the UK has established a National Decade Committee to inspire and enable a whole-of-society approach to meeting the interconnected challenges to the ocean that we have heard about today.

[Chris Grayling]

The Minister referred to discussions that we had this week about these issues, when we spoke about the complexity of getting consent to reforest an area of the UK. Have she and her officials looked at what barriers there are, if any, to restoring areas of seagrass or kelp? If there are planning barriers, will she and her Department look at ways that we can alleviate the situation and make it easier to do that?

[Trudy Harrison]

It would not be appropriate for me to speak more about the work we are doing to speed up the way we plant trees in this country, as this is a debate about oceans. I am not the Minister directly responsible for oceans, so I will ask Lord Benyon to write to my right hon. Friend with more detailed information about any hold-ups that he has identified in the planning system, particularly around sea kelp.

Hon. Members referred to technologies, and the UK is a global leader in offshore wind. Through our offshore wind environmental improvement package, which is currently before the House as part of the Energy Bill, we are supporting the drive for net zero and energy security. The package will support the rapid deployment of offshore wind while protecting our precious marine environment through an innovative set of measures, including new environmental standards for offshore wind infrastructure, measures to enable strategic compensation and the establishment of a new marine recovery fund.

We know that the sea will only get busier. My Department is leading the cross-governmental marine spatial prioritisation programme to optimise use of our sea space and work together to increasingly co-locate uses where possible. That includes our domestic fishing industries. We are working to ensure that the industries are sustainable environmentally, economically and socially, with a diverse fishing fleet run by a fishing industry with whom we are committed to working much more closely. Of course, supporting our fishing communities through this transition is vital. We recognise the fantastic work they do, and the provision of fish and seafood continues to be an absolute priority. We have developed regional fisheries management groups and are making good progress on DEFRA’s first six frontrunner fisheries management plans. Those plans are being prepared for public consultation, building on a huge amount of engagement that has already taken place, and five FMPs will be published by the end of 2023.

As I have set out, we have good reason to be proud of the UK’s commitment and also its leadership, working with other countries. We have secured progress on many international agreements and continue to champion ocean protection here and internationally. Collaboration and awareness raising are vital, and the debate has certainly raised awareness. I hope I have been able to demonstrate the successful collaboration and outcomes that have come from those international negotiations and agreements.

That brings me back to the importance of World Ocean Day, which helps with both those aims. There is still much more to do and we can deliver together. I am grateful for the opportunity to speak in the debate about the work we are doing in DEFRA. I again thank my hon. Friend the Member for Hastings and Rye not just for the way in which she has enlightened us today, but for her continued passion for the environment. I very much look forward to visiting her constituency next week and meeting some of her farmers, who seem equally passionate about the transition towards much more environmental stewardship in food production. I look forward to seeing her there.

[Sally-Ann Hart]

I thank the Minister for her comprehensive speech and her agreement that more needs to be done despite the UK’s global leadership on this matter. She might be interested to know that the APPG’s next inquiry is on the future of ocean technology, where there is some exciting stuff going on.

I thank my right hon. Friend the Member for Chipping Barnet (Theresa Villiers), who highlighted the need for more research and data, the issue of plastic pollution and the leading role that the UK plays globally in combating that. I thank my right hon. Friend the Member for Epsom and Ewell (Chris Grayling), who highlighted the importance of ocean-based solutions to climate change, the acute need to protect, restore and enforce our marine protected areas, which also protect our UK fishing livelihoods, and the role that the UK can play globally in this.

I thank the SNP spokesperson, the hon. Member for North Ayrshire and Arran (Patricia Gibson), and the shadow Minister, the hon. Member for Leeds North West (Alex Sobel), for their valuable contributions, illustrating—almost—that our ocean is not something that separates us, but which joins us together in political action.

Question put and agreed to.

Resolved,

That this House has considered World Ocean Day.
