New York has launched a major legal action against some of the world’s largest chemical manufacturers, opening another chapter in the growing legal battle over corporate responsibility for environmental harm caused by industrial products.

The lawsuit, filed by New York Attorney General Letitia James in Albany state court, targets companies including 3M, DuPont, The Chemours Company, Corteva, and EIDP over allegations that they contributed to widespread contamination linked to per- and polyfluoroalkyl substances (PFAS), commonly known as “forever chemicals”.

The case raises a question confronting courts around the world: when commercial products leave behind long-term environmental consequences, who should bear the financial and legal responsibility for addressing the damage?

New York is seeking, among other remedies, contributions towards environmental remediation, compensation for alleged damages, measures requiring greater disclosure about PFAS risks, and other relief aimed at addressing contamination associated with the chemicals.

The Long Shadow of ‘Forever Chemicals’

PFAS are a group of synthetic chemicals valued for their resistance to heat, water, and oil. For decades, they have been used in a wide range of consumer and industrial products, including firefighting foams, stain-resistant materials, and other specialised applications.

Their durability, however, has become the source of significant environmental concern. Because PFAS do not easily break down, they can remain in the environment for extended periods, accumulating in soil, water sources, and living organisms.

Scientists and regulators have raised concerns about possible links between certain PFAS exposures and serious health effects, including immune system problems, developmental concerns, and certain cancers. These concerns have contributed to increasing regulatory scrutiny and a wave of litigation across the United States.

The controversy surrounding PFAS demonstrates a recurring problem in environmental law, which is products that provide economic and technological benefits can later become the subject of disputes over their environmental and public health consequences.

Allegations of Failure to Disclose Risks

New York’s lawsuit centres on allegations that chemical manufacturers were aware of potential risks associated with PFAS for decades but continued to manufacture and market products containing the chemicals without adequate warnings to consumers, regulators, and communities affected by contamination.

The state alleges that the companies’ conduct contributed to contamination and shifted the financial burden of cleanup and remediation onto public authorities and taxpayers.

The companies have not been found liable yet merely because the lawsuit has been filed. The allegations will have to be tested through the judicial process, including questions of causation, scientific evidence, regulatory history, and the extent of any knowledge the companies possessed at relevant times.

Those issues are likely to be central because PFAS litigation involves complex questions about historical conduct and evolving scientific understanding.

Environmental Litigation as a Path to Accountability

The New York case forms part of a wider movement in environmental litigation in the US where governments, municipalities, and public authorities are turning to courts to recover the costs associated with industrial contamination. Traditionally, environmental protection has largely been driven by legislation and regulatory enforcement. However, litigation has become an additional mechanism through which governments seek to impose financial responsibility on industries alleged to have contributed to environmental damage.

PFAS-related lawsuits have expanded significantly, with states and local authorities seeking compensation for the costs of removing the chemicals from drinking water supplies and addressing contamination.

Previous settlements demonstrate the financial stakes involved. In 2025, DuPont, Chemours, and Corteva reached a settlement reportedly worth about $2 billion with New Jersey over similar PFAS-related claims, highlighting the potential exposure facing companies involved in the production of these chemicals.

A Test of Corporate Responsibility

The outcome of New York’s lawsuit could influence the future direction of environmental liability claims involving chemical manufacturers.

Could companies that manufactured and profited from products containing persistent chemicals bear the costs of addressing the consequences associated with those products?

A successful claim could strengthen efforts by governments and communities seeking compensation for environmental remediation and public health responses. It could also encourage further litigation against industries whose products create long-lasting environmental challenges.

However, the case will also require courts to navigate difficult questions about corporate responsibility, scientific knowledge, regulatory approval, and causation.

As PFAS litigation continues to expand, New York’s legal action represents another significant test of how far environmental law can go in holding corporations accountable for the long-term consequences of industrial activity.
