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. Scores are free. Nobody can pay to change a score, speed it up or hide it. Last verified May 2026.
That places E.ON joint 390th of 1,023 companies scored, and 6th of 21 in Energy Supply / Utilities.
