It is a pleasure to serve with you in the Chair, Dr Murrison. I am grateful to my hon. Friend the Member for Chatham and Aylesford (Tristan Osborne), a fellow south-east coast MP, for securing this debate, and to all those who intervened. I also congratulate my hon. Friend on his leadership of the APPG. Marine issues, including sustainable fisheries, have only recently become part of my ministerial portfolio, so this is a very timely debate for me. I am pleased to have the chance to set out my stall. Our stewardship of the ocean matters. Our seas are central to so much of what we care about: nature recovery, food security, clean energy, coastal livelihoods and communities, climate resilience and our identity as an island nation. People rightly care deeply about the marine environment, but they also care about livelihoods, food production, energy security and the future of communities that depend on the sea. I pay tribute to campaigners and all those who work in the sector on these important matters. Having responsibilities across those issues will enable me to take a more strategic view, consider the whole picture and look for a balanced decision-making process that supports our prosperous fishing industry and healthier, more resilient seas. I want my Department to make decisions that recognise the connections. I also want our decisions to be rooted in evidence, engagement and long-term stewardship. The Government are committed to protecting and improving the marine environment, including playing our part in delivering the global biodiversity framework target to protect at least 30% of the ocean by 2030. Domestically, our marine strategy and environmental improvement plan provides an important framework for action, including our statutory target for at least 70% of marine protected area features to be in a favourable condition by 2042. We are committed to the effective protection of our comprehensive network of MPAs around the UK. In English waters, we are continuing to implement fisheries management byelaws, including introducing further protections in due course. That includes proposals to restrict bottom trawling, following the Marine Management Organisation's consultation last year. The MMO is carefully considering the significant number of responses received and will announce its response in due course. Such decisions are not always easy, and must be taken carefully, transparently and with a clear understanding of both environmental and socioeconomic impacts. We are also reviewing the English marine protected area network to consider whether sites are in the right places and have the right levels of protection. That matters because the network is effective only if it is ecologically coherent, well managed and able to respond to the pressures that our seas face now and in the future. Those pressures are increasing. Climate change is already altering the marine environment, affecting habitats, species distribution and the communities and industries that depend on them. At the same time, we must manage the impact of growing demands on our marine environment and space, including those resulting from the expansion of offshore wind. That expansion is essential to our clean power and energy security ambitions, but it must be delivered in a way that also supports marine recovery. Reforms led by the Department for Environment, Food and Rural Affairs, such as the marine recovery fund launched in December last year, will help unlock clean power while delivering effective compensation to protect nature. The marine recovery fund is one element of our offshore wind environmental improvement package, which aims to ensure continued protection of the marine environment while speeding up consent for offshore wind. Marine spatial prioritisation and co-location work will also help us manage competing demands, including offshore wind, fishing, conservation and other sea uses. That is exactly the kind of area where we need to look across Government goals and avoid treating each decision in isolation. We are also committed to supporting the fishing sector to adapt to growing pressures on marine space, and we will work with the industry to safeguard its long-term viability. I know that the European Commission is developing its Ocean Act, and I look forward to learning more about the important work that the EU is doing to cover both conservation and stewardship. Marine protection also relies on enforcing the rules. Responsibility for delivering on that and tackling marine pollution incidents depends on the nature of the incident and source of the pollution. A number of bodies have statutory roles in responding to marine pollution, while any investigation and enforcement action are matters for the relevant independent regulators and enforcement authorities. In the case of pollution originating from terrestrial sources, the Environment Agency has a key role to play, while the Maritime and Coastguard Agency has an important role if the pollution comes from a marine source. Fines and sentences are imposed independently by the courts, which determine the appropriate penalty based on the circumstances of each case and applicable sentencing guidelines. I can confirm to Members that DEFRA and the Environment Agency are engaging with the Ministry of Justice to strengthen the overall enforcement regime so that environmental offences carry meaningful consequences and provide a stronger deterrent against pollution. Links between marine protection and fisheries are particularly important. Food security is national security, and seafood has an important role to play. A sustainable fishing industry depends on healthy fish stocks and healthy seas. Fisheries management plans are helping us to take a more evidenced view of how we support fisheries sustainably. They demonstrate why fishery management and protection of the marine environment must be addressed together, and set out a range of short, medium and long-term actions to maintain or restore stocks to sustainable levels and to improve the marine ecosystem. We cannot, however, deliver ocean conservation alone. As my hon. Friend the Member for Chatham and Aylesford said in his opening remarks, the UK continues to play a leading role internationally in ocean protection, and it remains committed to delivering our shared global mission to halt and reverse biodiversity loss by 2030. We are proud to be a founder and chair of the Global Ocean Alliance, as well as ocean champion of the High Ambition Coalition for Nature and People, in which role we are committed to protecting and restoring the health of our ocean. We continue to work with partners to protect vulnerable ecosystems and coastal communities. The UK has bolstered these efforts by leveraging finance for the ocean through the Blue Planet Fund, which is our largest marine official development assistance programme. Also, I am delighted that in July the UK ratified the biodiversity beyond national jurisdiction agreement. It will enable greater conservation of the two thirds of the ocean that lie beyond national jurisdiction, and support the delivery of the global biodiversity framework, including the target to protect at least 30% of our ocean by 2030. Later this month, the International Whaling Commission will mark its 80th anniversary, and next month will also mark the 40th anniversary of the global moratorium on commercial whaling, but there is more work to do. The UK will be at the forefront of global efforts to protect and promote the welfare of whales and other cetaceans as the chair of the IWC conservation committee. We also look forward to being a leading voice on ocean issues at the UN biodiversity conference in October and the climate conference of the parties in November, and to engaging proactively in the work of the first meeting of the BBNJ conference of the parties next year. We are also working with international partners to secure a new international agreement to end plastic pollution that addresses the full life cycle of plastics and promotes a global circular economy. We are committed to reaching an agreement at the first round of negotiations in March 2027. Finally, this Government recognise the continuing need for high-quality science to support our domestic and international work, and to ensure that Government decisions are based on the best available evidence. The UK has a leading role to play in ocean science, and we regularly call on others to help us to address emerging ocean threats and to inform the implementation of our international commitments and management measures. As this debate has shown, effective ocean stewardship means taking a long-term and joined-up approach, both domestically and internationally. As I have said, bringing together marine and sustainable fisheries will help to balance environmental, social and economic considerations. By protecting and restoring the marine environment, supporting sustainable fisheries and coastal communities and grounding decisions in the best available evidence, we can help to secure healthier seas for future generations. I again thank my hon. Friend the Member for Chatham and Aylesford for securing today's debate, and for raising such important issues.
