In January 2021, President Biden signed an executive order Protecting Public Health and the Environment and Restoring Science to Tackle the Climate Crisis. [1] This order provided a clear signal that the Biden administration was recommitting the United States to climate initiatives guided by the best science. [2] With a renewed federal focus on addressing the climate crisis, federal agencies have been tasked with captur[ing] the full cost[] of greenhouse gas emissions as accurately as possible in order to engage in informed decision and policy making.[3] Consequently, agencies have been examining both old and new methods of measuring greenhouse gas emissions. One such measure that government agencies have readopted is the social cost of carbon.
