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. Fees pay for the review, never the result. Last verified May 2026.
That places Enphase Energy joint 278th of 847 companies scored, and 3rd of 10 in Electrical Equipment / Lighting.
