The values in Tables A-1 through A-3 are the same as those reported in the 2016 TSD and Addendum adjusted for inflation to 2020 dollars using the annual GDP Implicit Price Deflator values in U.S. Bureau of Economic Analysis (BEA) NIPA Table 1.1.9: 113.626 (2020)/ 92.486 (2007) = 1.228575 (U.S. BEA 2021). Values of SC-CO2 presented in this TSD are rounded to the nearest dollar; SC-CH4 and SC-N2O are rounded to two significant figures. The annual unrounded estimates are available on OMB’s website for use in regulatory and other analyses: https://www.whitehouse.gov/omb/information-regulatoryaffairs/regulatory-matters/#scghgs.
