Rosebank Development Faces New Sanctions Allegations
Campaigners and Green Party co-leader Zack Polanski have formally warned Prime Minister Keir Starmer that the Rosebank oil field, one of the UK's largest untapped offshore reserves, may violate international sanctions linked to the West Bank. The development, located west of Shetland, involves partial ownership by an Israeli firm with operations in occupied territories. The warning escalates pressure on the government to reassess the project's approval.
The Rosebank field, operated by Equinor with partners including Ithaca Energy, received final approval in late 2023. However, new legal analysis suggests the project's supply chain and investment structure could breach UK sanctions regulations concerning Israeli settlements. Polanski's letter, backed by environmental groups, demands an immediate independent review before drilling begins in 2026. The Prime Minister's office has acknowledged receipt but offered no timeline for response.
How Rosebank's Ownership Structure Triggers Sanctions Concerns
At the heart of the controversy is the stake held by Delek Group, an Israeli conglomerate with subsidiaries operating in the West Bank. UK sanctions, updated in 2024, prohibit economic activities supporting settlements deemed illegal under international law. Analysts argue that Rosebank's revenue streams could indirectly benefit Delek's settlement-linked ventures, creating a compliance gray area. Legal experts note that the UK government has not previously applied these sanctions to North Sea projects.
The sanctions regime, aligned with broader EU guidance, targets goods and services originating from Israeli settlements. Rosebank's operators have stated they operate independently of Delek's other business interests. However, campaigners counter that corporate separation does not negate financial flows. This legal ambiguity places the UK government in a difficult position, as it must balance energy security goals with its stated commitment to international law and human rights.
Political and Public Pressure Mounts on Starmer Government
Zack Polanski's intervention marks a significant political escalation, as the Green Party seeks to position itself as a watchdog on ethical investment. The letter, co-signed by over 30 civil society organizations, calls for a suspension of Rosebank's permits pending investigation. Polanski argues that approving the project undermines the UK's credibility in condemning settlement expansion. The government faces a delicate balancing act, as delaying Rosebank could impact domestic oil production targets.
Public opinion appears divided, with recent polling showing strong support for renewable energy but also concerns over energy prices and job security. Rosebank is projected to produce up to 500 million barrels of oil, supporting thousands of jobs in Scotland. However, climate activists argue that new fossil fuel projects contradict the UK's net-zero commitments. The controversy has also reignited debate over the North Sea's long-term role in Britain's energy mix.
Regulatory and Legal Framework Under Scrutiny
The UK's sanctions framework, administered by the Office of Financial Sanctions Implementation (OFSI), focuses on designated individuals and entities. Delek Group itself is not fully sanctioned, but its settlement-linked subsidiaries are. This distinction creates enforcement challenges, as OFSI must determine whether Rosebank transactions constitute indirect support. Legal scholars suggest that a definitive ruling could set a precedent for other international projects with similar ownership structures.
Industry insiders note that the sanctions issue was not raised during Rosebank's environmental impact assessment, which focused on emissions and marine biodiversity. This oversight has drawn criticism from transparency advocates who argue that regulatory reviews must consider geopolitical risks. The UK government has not publicly clarified whether a sanctions-specific assessment was conducted. Calls are growing for a public inquiry into how such risks were evaluated before approval.
Equinor and Ithaca Energy have issued statements emphasizing their compliance with all applicable laws. Both companies have committed to conducting thorough due diligence on their partners and suppliers. However, they have declined to comment on the specific allegations regarding Delek's West Bank operations. This silence has fueled speculation that internal legal teams are scrambling to assess exposure, with potential reputational damage looming if sanctions are confirmed.
Economic and Energy Security Implications for the UK
The Rosebank project is considered vital for the UK's energy security, with projections indicating it could supply 8% of domestic oil demand at peak production. Delaying or canceling the project could force increased reliance on imports from other regions, some with poorer human rights records. Energy analysts warn that sanctions-related disruptions could also deter future foreign investment in the North Sea, compounding decommissioning costs and job losses in the sector.
Conversely, proponents of withdrawal argue that the UK could redirect investment toward renewable projects, creating more sustainable employment. The government's own climate advisors have recommended a managed decline of North Sea production to meet 2050 targets. The Rosebank controversy has thus become a proxy battle for broader energy policy direction, with both sides using sanctions law to advance their agendas. The Treasury is reportedly monitoring the situation closely.
Scottish political leaders have expressed concern that the dispute could undermine devolved energy strategies. The Scottish Government supports North Sea development during the transition period but also champions climate leadership. First Minister John Swinney has called for a pragmatic resolution that respects both legal obligations and economic realities. This regional dimension adds further complexity, as Westminster's decisions will have disproportionate effects on Scottish communities.
Next Steps and Future Outlook for Rosebank
The coming weeks will be critical as the government weighs whether to launch a formal investigation. Legal experts suggest that OFSI could issue guidance clarifying whether oil field investments fall under existing sanctions definitions. Alternatively, the government may seek diplomatic assurances from Israeli authorities regarding settlement activities. Any decision will likely face legal challenges from either campaign groups or industry stakeholders, prolonging uncertainty.
For now, Rosebank's operators are proceeding with preparatory work, including subsea installation contracts. The project's timeline assumes first oil by late 2026, a schedule that could be disrupted by legal proceedings. Investors are closely watching developments, with shares in Ithaca Energy showing volatility since the sanctions warning became public. The situation underscores how geopolitical issues increasingly intersect with energy markets in unpredictable ways.
Regardless of the outcome, the Rosebank case has set a precedent for how the UK navigates complex international sanctions in its domestic energy sector. Campaigners hope the scrutiny will force greater transparency in corporate ownership structures and supply chains. Industry groups worry about regulatory unpredictability. Ultimately, the government's response will signal its commitment to balancing legal obligations, energy needs, and ethical considerations in an increasingly interconnected world.
