Australia has filed a lawsuit against US industrial conglomerate 3M over its firefighting foams containing per- and polyfluoroalkyl substances (PFAS), commonly known as ‘forever chemicals’. The suit, lodged in the Federal Court of Australia, alleges that 3M knowingly sold products that contaminated water supplies and caused environmental damage, without adequately warning authorities. This is the latest front in a growing global backlash against PFAS, which are linked to health issues including cancer and immune system disruption.
For taxpayers, the bottom line is clear: remediation costs for PFAS contamination are staggering. The Australian government estimates cleanup could run into billions of dollars, a burden that will ultimately fall on the public purse. Market reaction was muted, with 3M’s shares dipping only fractionally, but the legal liabilities are mounting.
The company faces similar claims from US states and municipalities, and this Australian suit could set a precedent for other nations. From a fiscal perspective, governments are realising that the long-term costs of chemical pollution dwarf the short-term profits of manufacturers. It is a classic case of externalised costs coming home to roost.
The question now is whether 3M will settle or fight, and whether shareholders will finally demand accountability for the risks that have been swept under the carpet for decades.
