U.S. Climate Regulation Database

This is a database of regulations and other actions by federal agencies that are relevant to climate change mitigation and adaptation. The database includes links to archived versions of proposed and final regulations as well as technical support documents, regulatory impact analyses, agency guidance, and other relevant resources.

This database includes both steps taken to address the impacts and causes of climate change, as well as attempts to roll back or eliminate such actions. Our Climate Deregulation Tracker provides additional information about the Trump administration’s efforts to weaken climate policies that the Obama administration put in place. Our Climate Reregulation Tracker follows the Biden administration’s progress in reinstating and strengthening those policies. 

Regulations are organized by agency and then by subject matter. Click on the images below to learn more about the climate change regulations, guidance, and other policy documents issued by each department.
