Dr Savage urges the Government to ensure proper co-ordination, funding, enforcement mechanisms, and transparency in implementing the BBNJ treaty.

  • Mark Field Con Sheffield Hallam

    Our scientists are ready to lead. The National Oceanography Centre, with its cutting-edge research and fleet of autonomous submersible vessels—including one known as Boaty McBoatface—is already mapping deep sea currents and gathering the knowledge we need to understand and protect the ocean.

  • Barry Gardiner Lab Brent West

    The BBNJ treaty is the missing part of the jigsaw. It creates a framework for the establishment of protected areas on the high seas, but it does not create those protected areas itself. We must do so not in order to understate what the Bill does, but to understand clearly what action we must take following its passage.

  • Barry Gardiner Lab Brent West

    I pay tribute to the work of the previous Conservative Administration, who expanded the blue belt programme to nominally protect more than 4 million sq km of ocean. However, given that £2 million of this £8.6 million comes from official development assistance, which itself is being cut, I hope it will not seem churlish if I ask that the programme be ringfenced for the future.

  • Barry Gardiner Lab Brent West

    The history of these great mammals shows just why we now need the BBNJ. Human greed will destroy biodiversity wherever it is found on our planet, unless we act decisively to regulate our most destructive activities.

  • Barry Gardiner Lab Brent West

    The UK has been a world leader with the blue belt programme, but at home we continue to practise the opposite of what we preach. Despite continued advice from scientists to reduce catch quotas, that reduction has not happened.

  • Barry Gardiner Lab Brent West

    High seas fisheries often have unimaginably high levels of bycatch. This is particularly true of tuna fisheries, because tuna often school with other pelagic species, such as dolphins, manta rays and billfish.

  • Charlotte Cane LD Ely and East Cambridgeshire

    European eels are critically endangered, facing threats such as climate change and pollution. Creating eel passes and banning bottom trawling in marine protected areas would protect these species. Measures to safeguard the Sargasso sea and other vital breeding grounds should be prioritised.

  • Emily Thornberry Lab Islington South and Finsbury

    The commitment to the BBNJ treaty can be tested by how well we protect marine areas like those around the Chagos islands. These waters are essential for preserving biodiversity and supporting endangered species globally.

  • The UK and Mauritian Governments are committed to promoting the conservation of the environment of the archipelago. However, there is no funding mechanism in place to ensure proper marine protection in the Chagos archipelago.

  • Wera Hobhouse LD Bath

    Expressed concern about the lack of a dedicated funding mechanism for marine protection in the Chagos agreement, emphasising the importance of following the example set by the BBNJ agreement to ensure future conservation efforts.

  • Emily Thornberry Lab Islington South and Finsbury

    Highlighted that there is no incentive or funding mechanism for marine protection in the Chagos archipelago, suggesting that the treaty should have followed the lead of the BBNJ agreement to ensure long-term environmental protection.

  • Steve Race Lab Exeter

    Welcomed the Government's leadership on this issue and supported the Bill for enacting the UN high seas treaty, emphasising its importance in protecting marine life and ecosystems globally. He also discussed the significance of the Met Office’s role in climate science and ocean research.

  • Martin Rhodes Lab Glasgow North

    Welcomed the Bill for signaling the Government's commitment to multilateralism, emphasising that it will help protect biodiversity in large expanses of seas beyond national waters. He also stressed the importance of implementing the treaty effectively and continuing to advocate for global marine protection.

  • Josh Fenton-Glynn Lab Calder Valley

    The Bill is crucial for protecting our oceans and biodiversity. The legislation will establish marine protected areas, regulate deep-sea mining and destructive fishing, and ensure equitable sharing of marine science benefits. It supports the 30% ocean protection by 2030 goal. The high seas are vital for carbon absorption, weather regulation, and oxygen production. We must take action to lead other countries in making a difference.

  • Chris Hinchliff Ind North East Hertfordshire

    The Bill is essential for protecting our natural environment by providing a legal framework to ratify the UN BBNJ agreement. It addresses the need for protection of deep sea ecosystems and endangered species from industrial fishing practices like bottom trawling. The UK must be at the table for the treaty’s first COP to protect its national interests, including the 8 million seabirds that rely on the high seas.

  • Josh Newbury Lab Cannock Chase

    Supporting the Bill as it enables the UK to ratify the UN BBNJ agreement and address threats like overfishing, pollution, and deep sea mining in international waters. The legislation will extend marine licensing requirements and mandate environmental outcome reports for harmful activities. It also ensures transparency in the collection of marine genetic resources, embedding safeguards like 'polluter pays' principle.

  • John Whitby Lab Derbyshire Dales

    The oceans are under strain from climate change, pollution, overfishing, habitat destruction, and plastics. The high seas treaty represents a significant step forward but the success will depend on enforcement and funding for marine protected areas. Bottom trawling should be banned in all marine protected areas to ensure their protection.

  • Tristan Osborne Lab Chatham and Aylesford

    The high seas treaty is a welcome move towards managing international waters, reflecting the obligation to create a system of management. The Bill creates licence for marine protection areas in international waters which supports genetic heritage research and conservation efforts. Questions remain about enforcement, dispute resolution, and funding.

  • Martin Rhodes Lab Glasgow North

  • Barry Gardiner Lab Brent West

    Stressed the importance of the ocean as a solution to climate change and questioned whether giving up on fisheries from EU with EU reset is fully supported.

  • Andrew Rosindell Con Romford

    Asked about guarantees that Mauritius will protect the Chagos archipelago in the same way as the UK, emphasising the need to ensure protection of this vital area under both Labour and Conservative Governments.

  • Seema Malhotra Lab Sheffield Central

    Responded that both the UK and Mauritius attach great importance to protecting marine biodiversity. The UK will still manage environmental protection on Diego Garcia and the surrounding 12 nautical miles, with ongoing discussions for a separate written agreement regarding a marine protected area.

  • Seema Malhotra Lab Sheffield Central

    Addressed concerns about protecting intellectual property rights, clarifying that the Secretary of State will not transmit information to the clearing-house mechanism that would be protected under intellectual property or trade secrets law. Reiterated the importance of ratification and implementation processes.
