Advisory Council on Historic Preservation

The Advisory Council on Historic Preservation (ACHP), an independent United States federal agency, is charged with the mission to promote the preservation of the nation's diverse historic resources. The ACHP advises the president and Congress on national historic preservation policy and also provides a public forum for stakeholders and the public to influence federal agency decisions regarding federal projects and programs that affect historic properties. The ACHP promotes the importance of historic preservation to foster an understanding of the nation's heritage and the contribution that historic preservation can make to contemporary communities, along with their economic and social well-being.
In 2025, Trump issued an executive order that implemented leadership changes at the ACHP to expedite energy projects under the auspices of a "National Energy Emergency", which permitted fossil development on federal lands while preventing new clean energy projects.
