Overview
On 31 March 2026, financial think tank Planet Tracker published a major new report titled PFAS: From non-stick to stuck in court, accompanied by a first-of-its-kind litigation risk dashboard covering 1,079 publicly listed companies and more than 5,200 associated facilities globally. The report finds that the enormous financial and legal fallout from per- and polyfluoroalkyl substances (PFAS) is no longer contained within the upstream chemical manufacturing sector. It is moving aggressively down supply chains and into businesses that used these chemicals in their operations, sometimes decades ago, without ever producing them. Textiles manufacturers, food packaging producers, general industrial facilities, and a wide range of downstream users now face material remediation liabilities and reputational harm that they may not have anticipated or disclosed to investors.
The report draws an explicit parallel between PFAS litigation and the legal trajectories of asbestos and tobacco, two of the most consequential mass tort episodes in corporate history. Planet Tracker notes that in the United States alone, more than 15,000 active PFAS-related lawsuits are currently consolidated in federal courts. That volume of litigation has produced multibillion-dollar settlements and judgements that are materially affecting corporate valuations, cash flows, and credit profiles across multiple industry sectors. The report warns that because PFAS are persistent by nature, and because the body of health evidence linking exposure to serious illness continues to strengthen, the legal and financial exposure will compound over time rather than diminish.
For Australian environmental professionals, contaminated land consultants, M&A advisors, and their clients in the property, development, and financial sectors, this report represents a meaningful recalibration of how PFAS risk must be assessed and communicated. The assumption that a site is low risk simply because it is not a fire training area, an airport, or a primary chemical plant is no longer tenable. The Planet Tracker findings heighten the professional obligation to interrogate secondary and downstream PFAS exposure pathways with the same rigour previously reserved for known high-risk site types.
Key details
Planet Tracker’s PFAS litigation risk dashboard is the first publicly available tool of its scale and scope. It scores 1,079 publicly listed companies on their exposure to PFAS-related litigation and remediation liability, covering 5,200-plus facilities worldwide. The scoring methodology draws on publicly available data including facility operating histories, known PFAS-associated industrial activities, regulatory enforcement records, and disclosed litigation positions. The dashboard is designed specifically for investors and lenders who need to quantify environmental liability as a component of corporate credit and valuation analysis, not merely as an ESG checkbox exercise.
The report documents that PFAS litigation has become one of the largest environmental mass torts in history. The US$10.3 billion (approximately AU$16 billion) settlement reached by 3M in 2023 with US water utilities, and the separate multibillion-dollar settlements by DuPont and its spin-off entities, are cited as anchor data points. However, Planet Tracker’s analysis goes further by demonstrating that these headline settlements involve upstream manufacturers, while the next wave of litigation is targeting the far larger universe of downstream users who incorporated PFAS-containing materials into their products or processes. Industries identified as facing elevated exposure include apparel and textiles, food and beverage packaging, non-stick cookware supply chains, firefighting equipment users, semiconductor manufacturing, and general industrial facilities that used PFAS-based surface treatments or cleaning agents.
The persistence of PFAS in soil and groundwater is central to the financial argument. Unlike many industrial contaminants that degrade over time, PFAS compounds do not break down under natural environmental conditions, which means historical use at a facility creates a long-tail liability irrespective of when operations ceased. The report highlights that health-based investigation thresholds for PFAS in drinking water continue to tighten globally as new epidemiological evidence emerges. In the United States, the Environmental Protection Agency finalised maximum contaminant levels for six PFAS compounds in drinking water in 2024, including a limit of 4 nanograms per litre (4 ng/L) for both perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS), a threshold so low it effectively signals zero acceptable residual contamination from an engineering remediation standpoint. These tightening standards directly drive remediation cost estimates and, by extension, the litigation damages being sought against responsible parties.
Planet Tracker’s methodology for assessing litigation risk is explicitly financial rather than purely regulatory. The report models how unquantified PFAS liabilities function as off-balance-sheet risks that distort true enterprise value, affect credit ratings, and create disclosure obligations under securities law. The think tank warns that companies which have not yet been named in litigation but carry material PFAS exposure through historical operations represent a latent liability pool that investors and lenders are increasingly unable to ignore. The dashboard is intended to make that latent exposure visible at a portfolio level for the first time.

Australian context and implications for NEPM 2013, PFAS NEMP 3.0, and contaminated land practice

Background and context
Headline Summary: Planet Tracker releases major report and dashboard warning investors and downstream users of expanding PFAS litigation and remediation risks.
On 31 March 2026, financial think tank Planet Tracker published a significant new report, “PFAS: From non-stick to stuck in court,” highlighting that the financial and legal fallout of "forever chemicals" is rapidly moving down the supply chain. While historical regulatory and legal focus has centered on upstream chemical manufacturers and high-risk hotspots (such as airports and defence sites), the report warns that downstream users—including textiles, packaging, and general manufacturing facilities—now face severe local remediation liabilities and reputational damage, despite never manufacturing the chemicals themselves.
To help quantify this exposure, Planet Tracker has launched a new PFAS litigation risk dashboard that scores 1,079 publicly listed companies and over 5,200 associated facilities globally. The report notes that PFAS litigation has ballooned into one of the largest environmental mass torts in history, creating multibillion-dollar liabilities that are materially impacting corporate valuations, cash flows, and credit profiles.
Why it matters for environmental professionals:
For Australian contaminated land consultants, M&A advisors, and ESG practitioners, this represents a fundamental shift in how Environmental Due Diligence (EDD) and corporate risk reporting must be conducted:
