UK Critical Mineral Reliance Threatens Tech and Net-Zero Goals

Britain's goals for clean energy, artificial intelligence, and advanced semiconductors are at risk due to a heavy reliance on mineral supply chains dominated by China, according to reporting from The Register.

In a report published November 6, 2026, the House of Commons Business, Innovation, Science and Trade Committee stated it cannot confidently confirm that the government passes any of ten security tests designed to secure critical minerals. These tests evaluate whether ministers have identified necessary technologies, required minerals, potential disruption points, and plans for financing, skills, and domestic production.

While mining is a factor, the committee notes that processing is the primary bottleneck. Based on figures from the International Energy Agency, the report notes that China leads as the refiner for 19 of 20 strategic minerals, maintaining a 70 percent average market share. Specific vulnerabilities include gallium and germanium—used in electronic warfare and radar—where China accounts for 95 percent and 93 percent of global production, respectively. The committee also noted that China effectively monopolizes the processing of yttrium and erbium.

Committee chair Liam Byrne warned that Britain cannot deliver net zero or build AI without securing these minerals, noting that the UK remains "dangerously exposed" sixteen years after China first weaponized rare earth chokeholds. The committee estimates that diversifying these supplies will take 10 to 15 years.

To mitigate this, the committee proposes a five-part plan: identifying protected capabilities, mapping mineral needs, expanding domestic recycling and mining, pooling purchasing power with allies, and creating a Critical Minerals Finance Facility. The report further recommends expanding the remit of UK Export Finance and allowing British International Investment to take equity stakes in overseas projects.
