of the Environmental Protection Agency, shall conduct a 
study of— 
(1) published methods for evaluating the 
lifecycle fossil and renewable carbon content of fuels, 
including conventional and advanced biofuels; and 
(2) methods for performing simplified, stream-
lined lifecycle analyses of the fossil and renewable 
carbon content of biofuels. 
(b) REPORT.—Not later than 1 year after the date 
of enactment of this Act, the Secretary shall submit to 
the Committee on Energy and Natural Resources of the 
Senate and the Committee on Energy and Commerce of 
the House of Representatives a report that describes the 
results of the study under subsection (a), including rec-
ommendations for a method for performing a simplified, 
streamlined lifecycle analysis of the fossil and renewable 
carbon content of biofuels that includes— 
(1) carbon inputs to feedstock production; and 
(2) carbon inputs to the biofuel production 
process, including the carbon associated with elec-
trical and thermal energy inputs.

(1) IN GENERAL.—The Secretary, in consulta-
tion with the Secretary of Transportation, shall con-
duct a study of the adequacy of railroad transpor-
tation of domestically-produced renewable fuel. 
(2) COMPONENTS.—In conducting the study 
under paragraph (1), the Secretary shall consider— 
(A) the adequacy of, and appropriate loca-
tion for, tracks that have sufficient capacity, 
and are in the appropriate condition, to move 
the necessary quantities of domestically-pro-
duced renewable fuel within the timeframes re-
quired by section 111; 
(B) the adequacy of the supply of railroad 
tank cars, locomotives, and rail crews to move 
the necessary quantities of domestically-pro-
duced renewable fuel in a timely fashion; 
(C)(i) the projected costs of moving the do-
mestically-produced renewable fuel using rail-
road transportation; and 
(ii) the impact of the projected costs on 
the marketability of the domestically-produced 
renewable fuel; 
(D) whether there is adequate railroad 
competition to ensure—

(i) a fair price for the railroad trans-
portation of domestically-produced renew-
able fuel; and 
(ii) acceptable levels of service for rail-
road transportation of domestically-pro-
duced renewable fuel; 
(E) any rail infrastructure capital costs 
that the railroads indicate should be paid by the 
producers or distributors of domestically-pro-
duced renewable fuel; 
(F) whether Federal agencies have ade-
quate legal authority to ensure a fair and rea-
sonable transportation price and acceptable lev-
els of service in cases in which the domestically- 
produced renewable fuel source does not have 
access to competitive rail service; 
(G) whether Federal agencies have ade-
quate legal authority to address railroad service 
problems that may be resulting in inadequate 
supplies of domestically-produced renewable fuel 
in any area of the United States; and 
(H) any recommendations for any addi-
tional legal authorities for Federal agencies to 
ensure the reliable railroad transportation of
