Editor's note: The regulatory tracker was last updated on March 31, 2026. Rules are up to date as of March 30, 2026.

As the Trump administration returns to office for a second term with renewed deregulatory ambitions, the executive branch and its agencies are implementing significant policy changes. The Brookings Center on Regulation and Markets Regulatory Tracker (“Reg Tracker”) provides background information and status updates on a curated selection of significant regulatory and deregulatory changes made by the Trump administration. This tracker allows you to monitor a curated selection of new, delayed, and repealed rules, notable guidance and policy revocations, executive actions, and important court battles across key policy areas such as environmental, health, labor, and more.

The Reg Tracker focuses on major regulatory changes implemented under the current Trump administration. Entries we tracked during the Biden administration and during President Trump’s first term can be accessed through the “Biden” or “Trump Term 1” archive checkboxes, respectively.

For a more thorough explanation of the Reg Tracker, including an explanation of how entries are selected, an overview of the rulemaking process, and guidance on how to use the Reg Tracker’s interactive features, click here .
