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.
