What are the Renewable Fuel Standards?

(a) The values of the renewable fuel standards are as follows: Table 1 to Paragraph ( a )—Annual Renewable Fuel Standards Year Cellulosic biofuel standard (%) Biomass-based diesel standard (%) Advanced biofuel standard (%) Renewable fuel standard (%) Supplemental total renewable fuel standard (%) 2010 0.004 1.10 0.61 8.25 n/a 2011 n/a 0.69 0.78 8.01 n/a 2012 n/a 0.91 1.21 9.23 n/a 2013 0.0005 1.13 1.62 9.74 n/a 2014 0.019 1.41 1.51 9.19 n/a 2015 0.069 1.49 1.62 9.52 n/a 2016 0.128 1.59 2.01 10.10 n/a 2017 0.173 1.67 2.38 10.70 n/a 2018 0.159 1.74 2.37 10.67 n/a 2019 0.230 1.73 2.71 10.97 n/a 2020 0.32 2.30 2.93 10.82 n/a 2021 0.33 2.16 3.00 11.19 n/a 2022 0.35 2.33 3.16 11.59 0.14 2023 0.48 2.58 3.39 11.96 0.14 2024 0.59 2.82 3.79 12.50 n/a 2025 0.71 3.15 4.31 13.13 n/a 2026 0.79 5.24 6.42 15.50 n/a 2027 0.84 5.37 6.61 15.78 n/a (b) Except as specified in paragraph (c) of this section, EPA will calculate the annual renewable fuel percentage standards using the following equations: Where: Std CB,i = Cellulosic biofuel standard for year i, in percent. Std BBD,i = Biomass-based diesel standard for year i, in percent. Std AB,i = Advanced biofuel standard for year i, in percent Std RF,i = Renewable fuel standard for year i, in percent. RFV CB,i = Annual volume of cellulosic biofuel required by 42 U.S.C. 7545(o)(2)(B) for year i, or volume as adjusted pursuant to 42 U.S.C. 7545(o)(7)(D), in gallon-RINs. RFV BBD,i = Annual volume of biomass-based diesel required by 42 U.S.C. 7545(o)(2)(B) for year i, in gallon-RINs. RFV AB,i = Annual volume of advanced biofuel required by 42 U.S.C. 7545(o)(2)(B) for year i, in gallon-RINs. RFV RF,i = Annual volume of renewable fuel required by 42 U.S.C. 7545(o)(2)(B) for year i, in gallon-RINs. G i = Amount of gasoline projected to be used in the covered location for year i, in gallons. D i = Amount of diesel projected to be used in the covered location for year i, in gallons. RG i = Amount of renewable fuel projected to be contained in the projection of G i for year i, in gallons. RD i = Amount of renewable fuel projected to be contained in the projection of D i for year i, in gallons. GE i = Amount of gasoline projected to be exempt for year i, in gallons, per §§ 80.1441 and 80.1442. DE i = Amount of diesel fuel projected to be exempt for year i, in gallons, per §§ 80.1441 and 80.1442. (c) For the 2026 and 2027 compliance years, EPA will calculate the annual renewable fuel percentage standards using the following equations: Where: Std CB,i = Cellulosic biofuel standard for year i, in percent. Std BBD,i = Biomass-based diesel standard for year i, in percent. Std AB,i = Advanced biofuel standard for year i, in percent Std RF,i = Renewable fuel standard for year i, in percent. RFV CB,i = Annual volume of cellulosic biofuel required by 42 U.S.C. 7545(o)(2)(B) for year i, or volume as adjusted pursuant to 42 U.S.C. 7545(o)(7)(D), in gallon-RINs. RFV BBD,i = Annual volume of biomass-based diesel required by 42 U.S.C. 7545(o)(2)(B) for year i, in gallon-RINs. RFV AB,i = Annual volume of advanced biofuel required by 42 U.S.C. 7545(o)(2)(B) for year i, in gallon-RINs. RFV RF,i = Annual volume of renewable fuel required by 42 U.S.C. 7545(o)(2)(B) for year i, in gallon-RINs. SRERV BBD,i = Small refinery exemption reallocation volume for biomass-based diesel for year i, in gallon-RINs. SRERV AB,i = Small refinery exemption reallocation volume for advanced biofuel for year i, in gallon-RINs. SRERV RF,i = Small refinery exemption reallocation volume for renewable fuel for year i, in gallon-RINs. G i = Amount of gasoline projected to be used in the covered location for year i, in gallons. D i = Amount of diesel projected to be used in the covered location for year i, in gallons. RG i = Amount of renewable fuel projected to be contained in the projection of G i for year i, in gallons. RD i = Amount of renewable fuel projected to be contained in the projection of D i for year i, in gallons. GE i = Amount of gasoline projected to be exempt for year i, in gallons, per §§ 80.1441 and 80.1442. DE i = Amount of diesel fuel projected to be exempt for year i, in gallons, per §§ 80.1441 and 80.1442. (d) The price for cellulosic biofuel waiver credits will be calculated in accordance with § 80.1456(d) and published on EPA's website.
