Ecotricity scores 45/100 (Below expectations) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified May 2026.
That places Ecotricity joint 247th of 807 companies scored, and 4th of 21 in Energy Supply / Utilities.
Ecotricity supplies 100% green electricity but 99% fossil gas, masking its true emissions footprint. The company does not formally report Scope 3 combustion emissions (~293,000 tonnes CO₂e annually). A 2024 greenwashing investigation exposed carbon credit gaps. Operational emissions have fallen sharply, but the core business model remains unaligned with climate claims.
