In a landmark legal move, the Australian government has launched a lawsuit against American conglomerate 3M, accusing the company of concealing the environmental and health risks of per- and polyfluoroalkyl substances (PFAS), commonly known as ‘forever chemicals’. The case, filed in the Federal Court of Australia, seeks compensation for widespread contamination of water sources and ecosystems linked to the company’s firefighting foams and industrial products. This action underscores a global reckoning with the enduring legacy of PFAS, which do not break down in the environment and have been linked to cancers, immune system damage, and reproductive harm.
Meanwhile, Britain’s recent ban on PFAS in firefighting foams and consumer products is being hailed as a gold standard for regulatory action. The UK government’s phased approach, which began with a restriction on non-essential uses in 2021 and culminated in a near-total ban this year, has drawn praise from environmental groups and public health advocates. The ban is expected to eliminate the primary sources of PFAS contamination in drinking water, a move that the Australian lawsuit seeks to replicate through litigation.
The legal action against 3M, which also names other manufacturers like DuPont, alleges that the company knew about the toxicity of PFAS as early as the 1970s but chose to suppress this knowledge. Internal documents leaked during previous US lawsuits revealed that 3M referred to PFAS as ‘the material that won’t go away’. The lawsuit seeks damages for cleanup costs and health monitoring for affected communities, notably near military bases and airports where Aqueous Film Forming Foam (AFFF) was used extensively.
Australia’s move cannot be seen in isolation. It mirrors a wave of class-action lawsuits in the United States, where over 6,000 cases have been consolidated into multidistrict litigation. In Europe, the European Chemicals Agency is evaluating a sweeping ban on PFAS, while the UN Stockholm Convention has listed several PFAS compounds for global elimination. The scientific consensus is clear: no level of exposure to these chemicals is safe. They have been found in the blood of 97% of Americans and in countless wildlife species, from polar bears to dolphins.
Britain’s ban, which came into effect for firefighting foams in 2022 and expanded to cosmetics and textiles in 2024, demonstrates that a prosperous economy can transition away from PFAS without compromising safety. The Fire Brigades Union supported the ban, noting that alternative fluorine-free foams are now available and effective. The regulatory framework sets a global precedent, showing that the precautionary principle can drive policy without stoking panic.
As a technology and innovation lead, I see this as a pivotal moment for chemical accountability. The rise of blockchain and advanced tracing technologies could help consumers verify PFAS-free products, much like QR codes for organic food. Meanwhile, quantum computing may soon model the complex chemical pathways of PFAS degradation, aiding in cleanup efforts. But the core issue is one of ethics: companies must be held responsible for the full lifecycle of their inventions. The ‘move fast and break things’ mentality has no place when the thing being broken is the planet’s bloodstream.
The Australian lawsuit and Britain’s ban are twin prongs of a necessary revolution. They signal that the era of unaccountable chemical engineering is over. For citizens, this means cleaner water and reduced cancer risks. For innovators, it is a call to design materials that are truly sustainable, not just convenient. The long shadow of these ‘forever chemicals’ is finally being brought into the light, and the message is clear: no company is above the law, and no molecule is beyond scrutiny.
