Research & Developments is a blog for brief updates that provide context for the flurry of news regarding law and policy changes that impact science and scientists today.
The number of peer-reviewed scientific studies authored by scientists at the EPA has declined since the beginning of Donald Trump’s second administration, according to a new analysis.
The analysis was published by Public Employees for Environmental Responsibility (PEER), a nonprofit organization that advocates for public employees in the natural resource and environmental professions. The report tracks the number of peer-reviewed scientific studies authored by EPA scientists since 1977.
According to PEER’s analysis, 61 peer-reviewed publications by EPA scientists have been published so far this year, putting the agency on track to publish 183 articles by the end of 2026. That would be 67% of the number of articles published the previous year and 54% of the number of articles published in 2024.
“These numbers represent a diminution of scientific contributions from the fewer, remaining EPA scientists,” Kyla Bennett, a science policy director at PEER and a former EPA attorney, said in a statement. “The net result is that the scientific contribution of EPA to a greater understanding of what affects human health and the environment will be diminished.”
Peer-reviewed publications can take years to review and publish, meaning the work for a publication may have occurred during a previous administration. But the decline in publications may indicate a shift away from long-term basic research at the agency, according to PEER.
Since Trump took office, hundreds of scientists have been terminated from the EPA or have chosen to resign, and scientists working within at least one of its research office have been told to pause efforts to publish research, representing “millions of dollars of research, potentially, that’s now being stopped,” one EPA employee told The Washington Post anonymously.
In February, the EPA took final steps to eliminate the Office of Research and Development, the arm of the agency responsible for conducting research. In its place, Administrator Lee Zeldin announced that a new office, called the Office of Applied Science and Environmental Solutions, would be formed but would not operate as a separate division.
Six EPA scientists who signed an open letter expressing frustration about changes to the agency, including the elimination of the Office of Research and Development, were terminated and have filed claims with the federal government arguing that their terminations were illegal retaliation.
