Westminster has put the UN High Seas Treaty into domestic law. The Biodiversity Beyond National Jurisdiction Act 2026 received Royal Assent on 12 February 2026, according to legislation.gov.uk. For ports on the Tyne and Humber and for university labs from Newcastle to Hull, this sets out how UK-led science and commercial R&D can operate in waters beyond any nation’s control.

The Act implements the treaty opened for signature in New York in September 2023 and uses its definitions, including “areas beyond national jurisdiction” and “marine genetic resources”. In plain terms, it covers UK ships and UK-controlled projects that collect or use genetic material from the high seas, and it reaches into onshore labs when that material or its digital sequence information is used here in the UK.

Before a UK craft heads out to collect marine genetic resources on the high seas, the lead scientist must provide detailed pre‑collection information to the Secretary of State. As a default, there’s a seven‑month wait from submission before samples can be taken. That clock can be shortened if there’s a compelling reason, but expeditions launching from the Tees, Tyne or Humber will now need longer lead‑times baked into their planning.

After sampling, post‑collection details must be sent “as soon as available” and no later than eleven months after the last collection day. Any samples used in UK utilisation projects must be deposited in a publicly accessible repository and any digital sequence information recorded in a publicly accessible database-both operating to current international practice-within three years of the project starting. All samples and data must be trackable using the treaty’s standardised identifiers.

When UK utilisation leads to publications, patents or product development, the Act requires information to be reported within one month of the result. If a product reaches the market, information must be given within one month of launch and then annually for as long as the product remains available. In short: biotech spin‑outs in places like Newcastle Helix or Leeds will need a compliance diary alongside their lab notebooks.

To support transparency, the Secretary of State may pass information to the treaty’s Clearing‑House Mechanism, except where protected by the National Security Act 2023 or where the treaty doesn’t require disclosure. That means much of the UK’s high seas research trail will be visible internationally, with limited carve‑outs.

Repositories and UK‑based databases holding high seas material or digital sequence information must keep it clearly identified as such and provide access for others, subject to reasonable conditions. Every two years they must report usage figures to the Secretary of State, giving the identifiers for the relevant samples or datasets. This formalises data‑sharing norms many Northern labs already follow, but with statutory teeth.

Day‑to‑day fishing is out of scope. Activities carried out under Fisheries Act 2020 licences, and work done to meet the scientific evidence objective in that Act, are excluded. So skippers in North Shields, Whitby and Fleetwood are not suddenly being dragged into a high seas biotech regime. Military activities and anything done in Antarctica are also excluded.

On benefit‑sharing, ministers gain powers to make regulations that could require disclosures and payments to implement decisions taken by the treaty’s Conference of the Parties. Civil sanctions and other enforcement tools can be created. The Act also guards against double compliance where a UK operator would otherwise face identical reporting to both the UK and another treaty party.

Devolution matters here. Scottish Ministers and Northern Ireland’s Department of Agriculture, Environment and Rural Affairs (DAERA) can make their own regulations in devolved areas, with affirmative or negative procedures set out on the face of the Act. That gives Edinburgh and Belfast a direct hand in how rules land for Aberdeen‑based research or Belfast‑led data projects, while cross‑border Northern supply chains will want to track both UK‑wide and devolved guidance.

If the treaty’s parties agree new high seas protected areas or emergency measures, the UK must give effect to them. The Secretary of State can make regulations, charge fees, and create civil or specified criminal offences to enforce those measures. In urgent cases, rules can be made first and approved after. Ministers can also issue written directions to UK craft; ignoring a direction without reasonable excuse is an offence carrying up to two years on indictment.

Licensing and environmental assessment law is updated. The Marine and Coastal Access Act 2009 now allows activities to be designated with high seas duties in mind, and environmental impact assessments are triggered for BBNJ activities where there are reasonable grounds to believe they may cause substantial pollution or significant and harmful changes-or where effects are unknown or poorly understood. For North Sea contractors laying or surveying cables that cross into the high seas, staging from Teesside or the Tyne, that raises the bar on screening and evidence.

Scotland makes parallel changes to marine licensing and EIA regulations. “BBNJ works” are brought squarely within the system, with the same emphasis on precaution when impacts are uncertain. Equivalent assessments by others can be accepted, but approvals must still be compatible with the UK’s treaty obligations.

Standards and guidelines adopted under Article 38 of the treaty can be brought into UK or Scottish licensing by regulation. Expect technical updates to flow through in step with international decisions, with operators needing to track consultations and adjust compliance plans accordingly.

Most of the Act took effect on the day it was passed, 12 February 2026, but key operational sections-covering pre‑ and post‑collection rules, benefit‑sharing enforcement and guidance-will start on dates set by regulations. For Northern universities, ports and offshore contractors, the immediate task is housekeeping: map projects that may touch high seas material, plan for the seven‑month pre‑notice where relevant, line up suitable repositories and databases, and make sure Article 12 identifiers and reporting lines are built into project design. The law is global in reach, but its paperwork will be managed on Tyneside, Teesside and the Humber. The detail sits on legislation.gov.uk; the workload sits here in the North.
