S. 3531 would require the federal government to produce the National Climate Adaptation and Resilience Strategy to address vulnerabilities of federal agencies to climate change. The bill also would establish the position of Chief Resilience Officer and would authorize working groups to coordinate efforts between agencies to adapt to climate change. The Government Accountability Office would assess both the strategy and its implementation within two years of completion. CBO estimates that enacting S. 3531 would have an insignificant effect on direct spending and no effect on revenues over the 2023-2032 period. CBO has not estimated the discretionary costs of implementing S. 3531. The bill contains no intergovernmental or private-sector mandates as defined in the Unfunded Mandates Reform Act.
