65+ Scientists to Government: North Sea Drilling is Not the Answer

Good Friday 2026 saw a striking piece of scientific advocacy land in the public debate: over 65 leading UK climate scientists published an open letter, reported across the Financial Times and Guardian, urging the government to resist pressure to approve new North Sea oil and gas drilling. The letter — signed by figures including Bill McGuire of University College London and Richard Allan — made three core arguments: the climate science is clear that we cannot burn more fossil fuels; most of the North Sea has already been exploited (around 90%); and the remaining resources would do almost nothing to reduce UK energy prices.

The political context is charged. Energy Secretary Ed Miliband is facing pressure from multiple directions — the Conservative opposition, Reform UK, trade unions worried about North Sea jobs, Scotland's Labour leader Anas Sarwar (who fears electoral consequences in the Scottish Parliament elections), and even parts of the Treasury under Chancellor Rachel Reeves, who has reportedly signalled support for more drilling. Against this stands the net-zero legal framework of the Climate Change Act, the UK's international climate commitments, and a significant portion of the scientific and environmental community.

The Case Against New Drilling

The scientists' argument rests on the numbers. The Rosebank and Jackdaw fields, the two most prominent candidates for new licensing, would displace only an estimated 1% and 2% of UK gas imports respectively. The North Sea basin is 90% depleted; extraction costs have risen 40% since 2019. Christiana Figueres, former UN climate chief, argues that new drilling 'risks locking in infrastructure that is increasingly out of step with the direction of the global energy system.' Lord Stern of the LSE says it would be 'bad for growth, bad for energy security, and send a damaging signal to the world.' An African climate negotiator, speaking anonymously, warned that UK drilling approval would undermine the Paris Agreement and destroy trust with climate-vulnerable nations who are being asked to keep their fossil fuels in the ground.

The UK Energy Research Centre stated in March 2026 that North Sea drilling 'will not reduce bills or deliver energy security.' The National Energy System Operator calculates that meeting net-zero would cut import dependency by 78%, while failing to decarbonise would see imports rising by a third as production falls.

The Case For

The industry body OEUK makes a different case in its Business Outlook 2026: that oil and gas still meets around 75% of UK energy needs, that domestic production reduces reliance on potentially more polluting LNG imports, and that without a supportive licensing environment, the UK will simply import more. Chief Executive David Whitehouse argues this is not 'either/or'; it is possible to pursue renewables aggressively while also maintaining domestic production. The Tony Blair Institute, in a fourth intervention on net-zero in 12 months, has backed approval of Jackdaw and Rosebank, arguing that Ed Miliband's approach is too 'ideological' and ignores practical energy security realities. Some economists argue that offshore wind contracts at around £91 per megawatt-hour are not as dramatically cheaper than gas as transition advocates suggest, particularly once backup and grid investment costs are included.

The Financial Sector Read

For regulated financial institutions, the North Sea debate is less about taking sides and more about what it signals for transition risk. A UK that approves significant new fossil fuel production sends a signal to investors, rating agencies, and international counterparties that its climate commitments are subject to geopolitical override. That shifts the risk premium on UK-domiciled clean energy assets, changes the ESG profile of UK equities with North Sea exposure, and has implications for the UK's standing in the sustainable bond market. Asset managers with net-zero commitments, stewardship obligations, and regulatory reporting requirements under ISSB S2 need to form a view about what the policy trajectory means for their portfolios over a 10-year horizon.

The Legal Angle

The North Sea drilling debate is already taking shape in the courts. The Rosebank judicial review, in which environmental group Uplift successfully challenged the government's approval of the Rosebank oilfield on the grounds that the environmental impact assessment had failed to account for the downstream combustion emissions of extracted oil, established that UK courts will scrutinise licensing decisions against the UK's statutory climate obligations. If the government approves Rosebank or Jackdaw in a modified form, further judicial review challenges are virtually certain. The Climate Change Act 2008 creates a statutory duty on the Secretary of State to reduce emissions; any licensing decision that materially undermines that duty faces litigation risk under judicial review principles, and the courts have shown they are willing to apply the Heathrow Airport ruling logic (which struck down an airport expansion policy for failing to account for Paris Agreement commitments) to energy decisions.

For the financial institutions that would finance new North Sea development, there are parallel legal considerations. Lenders and underwriters providing project finance for new oil and gas development in the current environment must assess whether those facilities are consistent with their own published net-zero commitments and transition plans. If a bank has published a sector policy restricting financing of new oil and gas exploration, and then finances Rosebank or Jackdaw, it may face civil claims from shareholders for misrepresentation and reputational exposure under consumer protection law from retail customers who were sold products on the basis of that bank's sustainability credentials.
