The Trump EPA has scrapped a scientific integrity policy released in the waning days of the Biden administration that aimed to limit political interference in the agency’s science.

The agency’s website Thursday no longer included the Biden administration’s revised scientific integrity policy that was released on Jan. 16 — four days before Trump’s second inauguration. The Biden version was available on EPA’s website as of late July, according to a screenshot taken from the Internet Archive.

EPA is revoking its 2025 EPA scientific integrity policy and reinstating its 2012 policy, an EPA spokesperson said in an email Thursday in response to questions about the changes to the agency’s website.

The move was made in response to an executive order President Donald Trump issued in May that directed agencies’ scientific integrity to be governed by “policies that existed within the executive branch on January 19, 2021,” the EPA spokesperson said.
