3M has cut operational emissions 59% ahead of SBTi targets but is defined by massive PFAS contamination across three continents. A $10.3–12.5 billion US settlement, Belgian criminal investigation, and Dutch liability claims reveal systemic environmental damage that no carbon reduction offsets. Water and nature scores collapse under documented pollution legacies.
3M Company scores 38/100 (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 3M Company joint 410th of 847 companies scored, and 3rd of 10 in Chemicals.
