E.ON has SBTi-validated 1.5°C targets with absolute reduction commitments, but delivery remains unverified. Scope 3 accounting exists yet lacks granular disclosure. Nature, water, and circular economy reporting are minimal or absent. Trade association membership with fossil fuel advocates undermines climate messaging.
E.ON scores 41/100 (Below expectations) on SINK's independent climate assessment, scored from public data only. Fees pay for the review, never the result. Last verified May 2026.
That places E.ON joint 343rd of 847 companies scored, and 6th of 20 in Energy Supply / Utilities.

Ecotricity supplies 100% green electricity but 99% fossil gas, masking its true emissions footprint.
See the breakdown →SSE publishes comprehensive GHG data with external assurance and holds SBTi-validated targets, but absolute emissions rose 10% in FY2024/25 due to increased thermal generation.
See the breakdown →OVO Energy reports detailed operational emissions cuts and has ditched greenwashing REGOs, but 9.8Mt of annual Scope 3 from gas supply to 4 million customers overwhelms progress.
