Pfizer discloses robust climate data with GHG Protocol alignment and SBTi validation, but progress is dire: only 15% of its 46% emissions reduction target achieved by 2024, renewable energy stuck at 14% despite RE100 membership, and hazardous waste flat since 2022. Critically, Pfizer's climate messaging is undermined by active membership in trade associations (US Chamber, NAM) that lobby against climate policy.
Pfizer scores 39/100 (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.
