On his first day in office on January 20, 2021, President Biden signed an Executive Order titled, “Protecting Public Health and the Environment and Restoring Science to Tackle the Climate Crisis” (the Order). The Order directed federal agencies to immediately begin a review of federal regulations and regulatory action over the last four years. The Order directed agency heads to consider revision, rescission, or suspension of regulations rather than directing any particular course of action. However, the Order illuminates the Biden Administration’s priorities with respect to the regulatory landscape for energy and the environment.
