3M

3M, one of the world’s largest makers of PFAS, will halt all production of these “forever chemicals” by the end of 2025, walking away from a business that brought in roughly $1.3 billion a year. The company expects to absorb up to $2.3 billion in pre-tax charges to exit — a sign it sees long-term liability as the bigger risk than lost revenue. The move follows mounting pressure from regulators, lawsuits, and a coalition of fund managers overseeing $8 trillion in assets who urged dozens of companies to phase PFAS out. Compounds linked to cancer, thyroid disruption, and developmental harm have turned up in drinking water and food supplies worldwide, and 3M’s deadline signals that the era of treating them as ordinary industrial inputs is drawing to a close.
