London, 9 July 2026 – New analysis from think tank Ember finds that Drax biomass power station was the UK’s largest emitter for the eleventh year running, with record emissions of 14.1 million tonnes of carbon dioxide equivalent (CO2e) in 2025.
Drax emitted four times as much CO2e as the second largest emitter, Pembroke gas power station, and more than the top six gas power stations combined.
Despite the scale of emissions, previous Ember analysis has shown that Drax received a record £999m in subsidies in 2025 for burning biomass for power generation, costing UK households £13 each.
