        Mr. Marshall, Mr. Ricketts, and Mr. Rounds):
  S. 3055. A bill to require the Administrator of the Environmental 
Protection Agency to update the modeling used for lifecycle greenhouse 
gas assessments for approved fuel pathways under the Renewable Fuel 
Standard, and for other purposes; to the Committee on Environment and 
Public Works.
  Mr. THUNE. Madam President, I ask unanimous consent that the text of 
the bill be printed in the Record.
  There being no objection, the text of the bill was ordered to be

                                S. 3055

       Be it enacted by the Senate and House of Representatives of 
     the United States of America in Congress assembled,

     SECTION 1. SHORT TITLE.

       This Act may be cited as the ``Adopt the Greenhouse gases, 
     Regulated Emissions, and Energy use in Transportation model 
     Act'' or the ``Adopt GREET Act''.

     SEC. 2. DEFINITION OF ADMINISTRATOR.

       In this Act, the term ``Administrator'' means the 
     Administrator of the Environmental Protection Agency.

     SEC. 3. LIFECYCLE GREENHOUSE GAS EMISSIONS FOR APPROVED FUEL 
                   PATHWAYS.

       (a) In General.--Subject to subsection (b), not later than 
     90 days after the date of enactment of this Act, and not 
     later than every 5 years thereafter, the Administrator shall 
     update the methodology used by the Environmental Protection 
     Agency in lifecycle analyses with respect to greenhouse gas 
     emissions that result from a fuel pathway to which a D code 
     has been assigned pursuant to a petition described in section 
     80.1416 of title 40, Code of Federal Regulations (or 
     successor regulations), that has been approved by the 
     Administrator.
       (b) Requirements.--
       (1) First update.--In carrying out the first update 
     required under subsection (a), the Administrator shall adopt 
     the most recent Greenhouse gases, Regulated Emissions, and 
     Energy use in Transportation model (commonly referred to as 
     the ``GREET model'') developed by Argonne National 
     Laboratory.
       (2) Subsequent updates.--In carrying out the second and 
     each subsequent update required under subsection (a), the 
     Administrator shall--
       (A) as necessary, adopt, review, or update a methodology 
     determined to be appropriate by the Administrator; or
       (B) adopt the methodology described in paragraph (1).
       (3) Establishment of fuel pathways.--For any fuel pathway 
     to which the Administrator assigns a D code pursuant to a 
     petition described in section 80.1416 of title 40, Code of 
     Federal Regulations (or successor regulations), that is 
     approved by the Administrator after the date of enactment of 
     this Act, the Administrator shall, not later than 90 days 
     after the date on which the Administrator assigns that code, 
     adopt the methodology described in paragraph (1) for purposes 
     of modeling lifecycle analyses with respect to greenhouse gas 
     emissions that result from that fuel pathway.
       (c) Report.--If the Administrator fails to carry out 
     subsection (b)(2) before the applicable deadline described in 
     subsection (a), the Administrator shall submit to the 
     Committees on Agriculture, Nutrition, and Forestry, Energy 
     and Natural Resources, and Environment and Public Works of 
     the Senate and the Committees on Agriculture, Energy and 
     Commerce, and Science, Space, and Technology of the House of 
     Representatives a report describing the reasons for the 
     failure to carry out subsection (b)(2), which may include a 
     determination by the Administrator that the methodology 
     adopted or updated in a previous update under subsection (a) 
     remains the most current methodology based on available data, 
     research, and technology.
