Trump Administration's EPA Relied on Industry Science to Weaken Formaldehyde Cancer Regulations
Newly disclosed documents expose a concerted effort by the Trump administration's Environmental Protection Agency (EPA) to dismantle stringent formaldehyde regulations, heavily influenced by chemical industry-funded research. The revelations highlight a significant policy reversal that replaced Biden-era protections with weaker standards, potentially endangering public health.
Industry Influence and Scientific Manipulation
The documents, obtained through a Freedom of Information Act request by the Environmental Defense Fund (EDF), detail how the Trump EPA in late 2025 moved to undo findings established by the Biden EPA in late 2024, which had determined that any exposure to formaldehyde increases cancer risk. Instead, the Trump administration adopted less protective figures, largely aligning with studies led by Rory Conolly, a scientist funded by chemical trade groups.
Between 2008 and 2024, the EPA had previously concluded that Conolly's research was outdated or unreliable. However, under Trump, the agency changed formaldehyde risk levels to match Conolly's assertion that some exposure is safe, at 0.3 parts per million (ppm). Advocates argue this move involved "cherrypicking" data, ignoring broader scientific consensus that cancer risks occur at lower levels.
Meetings and Conflicts of Interest
The documents also reveal an unusual three-day meeting in 2023 between the EPA and top formaldehyde producers, users, and trade groups, where Conolly presented. Maria Doa, a former EPA scientist now with EDF, stated that much of the justification was "based on what Conolly did," emphasizing the chemical lobby's aggressive tactics to protect profits.
Further conflicts of interest emerged with the appointment of former American Chemistry Council officials, Nancy Beck and Lynn Dekleva, to leadership roles in the EPA's chemical safety office. Their oversight directly influenced the regulatory changes, according to Kyla Bennett of Public Employees for Responsibility, who noted that industry attacks targeted key scientific bodies like the EPA's Integrated Risk Information System (Iris) and the National Academy of Science Engineering and Medicine (Nasem).
Broader Implications for Public Health
Erik Olson of the Natural Resources Defense Council Action Fund warned that this case sets a dangerous precedent, potentially allowing the re-evaluation and weakening of regulations for other carcinogens. He called for congressional investigation, noting that increased exposure to toxic chemicals could lead to higher healthcare costs and insurance bills for the public.
In response, the EPA defended its actions, claiming the Biden administration used "flawed analyses" and that the new assessment incorporates a wider range of views with "gold standard science." However, critics argue this stance contradicts decades of research and independent reviews, raising serious questions about regulatory integrity and public safety.
