Enphase Energy has published consistent ESG reporting aligned with major frameworks, but its decarbonisation commitments are weak. Scope 3 supply chain emissions lack full disclosure, targets are intensity-based rather than absolute, and the company has no SBTi validation. Critical gaps exist in biodiversity, water, and circular economy reporting.
Enphase Energy scores 44/100 (Below expectations) on SINK's independent climate assessment, scored from public data only. Scores are free. Companies can never pay for anything about their own score. Last verified May 2026.
That places Enphase Energy joint 306th of 934 companies scored, and 2nd of 12 in Electrical Equipment / Lighting.
