A UK city regulator has closed a probe into Drax, the power generation company, concerning its environmental claims about biomass. Reporting states that Drax—previously the UK’s largest coal-fired power station—now relies on wood pellets as fuel and imports millions of tonnes from Canada each year. The probe focused on how Drax describes the environmental impact of its biomass operations. Multiple outlets covering the same matter say the watchdog has decided to drop the investigation rather than pursue further action. The reports do not indicate that new findings change Drax’s approach, but they confirm the regulator’s decision to close the probe into the company’s public claims. The disclosures highlight the wider scrutiny around how biomass is sourced and assessed in environmental terms, particularly where fuel is imported internationally. Drax’s pellet supply chain and related emissions assessments remain central points of public attention, even though this specific regulatory inquiry is no longer ongoing.
