                                 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.

    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.
                                 <all>
