On January 20, 2021, President Biden issued Executive Order (E.O.) 13990, "Protecting Public Health and the Environment and Restoring Science to Tackle the Climate Crisis," to establish a national policy to empower our workers and communities; promote and protect our public health and the environment; and conserve our national treasures and monuments, places that secure our national memory. 86 FR 7037 (Jan. 25, 2021).
