Ecotricity excels at renewable electricity (100% green) but fundamentally fails on gas: 99% fossil fuel with no credible near-term reduction path. Scope 3 emissions (~293,000 tonnes CO₂e annually) are buried. A 2024 greenwashing investigation exposed carbon credit gaps. Operational emissions are trivial noise masking the real problem.
