Sustainable Seas

The Government have signed up to the 14th sustainable development goal target to prevent and significantly reduce marine pollution of all kinds by 2025. So here is our plan. We want to see the Government ban single-use plastic packaging that is difficult to recycle; introduce a 25p latte levy on disposable coffee cups, with all coffee cups to be recycled by 2023; and bring forward their deposit return scheme and extended producer responsibility schemes before the end of this Parliament. The Government must also set out how they will create and fund the UK’s domestic recycling industry to end the export of contaminated waste to developing countries.

Climate change is causing a triple whammy of harm from ocean acidification, ocean warming and deoxygenation. This harms the entire food web and disrupts our weather systems. The recent Intergovernmental Panel on Climate Change report showed us that a 2°C rise above pre-industrial levels will significantly harm biodiversity and fish stocks, and will destroy nearly all the coral reefs in the world. If we can keep the temperature rise to 1.5°, we will still lose 90% of coral reefs. Until we did this inquiry, I did not know that the UK has a cold-water reef in the south of England.

That is why we have to redouble our actions to reduce our greenhouse gas emissions and meet the Paris agreement on climate change. The Government must set out their plans to achieve that in the first half of this year and set a net-zero emissions target by 2050 at the very latest. Species affected by climate change include krill and plankton; if they are removed from the marine food chain, that could lead to a one-third collapse in the populations of predators such as polar bears, walruses, seals, sea lions, penguins and sea birds.

Britain’s overseas territories and their waters cover an area nearly 30 times the size of the UK, and nearly 90% of the UK’s biodiversity is located in their waters. They have the most unique and biodiverse areas on the planet, and we have a huge responsibility to protect them. We welcome the Government’s December announcement on the creation of a marine protected area for the South Sandwich Islands. We have also discussed with the Minister for Energy and Clean Growth, who is in the Chamber, how the exploitation of minerals from the deep sea could begin in the next decade. The prime sites are around the deep sea hydrothermal vents, but those habitats are unexplored and unique. We heard from scientists that in a very small-scale study they found six hitherto unknown species. This is the great last wilderness left on earth; in fact, it may be where life on earth first began. Mining those sites could have catastrophic impacts—from local extinctions of as yet unmapped ecosystems and species, to the production of sediment plumes, which can travel long distances through the water column, smothering seabed organisms. Our report urges the Government not to pursue licences at active hydrothermal vents in their own jurisdiction and internationally, and to use their experience in regulating marine industries and their influence on the International Seabed Authority to impose a moratorium on exploitation licences in those areas.

We heard how so much of the sea—58% of it—is outside national jurisdictions, has little or no protection and is suffering from the tragedy of the commons: everyone goes there to graze their sheep, but there is nothing left at the end. Everyone goes there to take their piece, but no one is protecting it. We must lead international negotiations. The Government have signed up to the UN’s ambition to protect 30% of the world’s oceans by 2030, but that will work only if our Government, alongside other nations, fund the satellite monitoring and enforcement mechanisms for those areas that we want to protect.

The UN is currently negotiating a high seas treaty. We call on the Government to seize this chance and push for a Paris agreement of the seas. Like the climate change agreement, it would contain legally binding targets and regular conferences of the parties to hold Governments to account, and designate marine protected areas and the funding needed to achieve them. We look forward to the publication of the Government’s international ocean strategy later this year. I hope it will include and build on our Committee’s cross-party ambitions.

We are an island nation. We care passionately about our seas and oceans. I commend the report to the House, and commend my Committee colleagues for such an excellent report.
