MODERATE
The bill was revised to remove the requirement for a preliminary feasibility study, mandating instead that the Department of Transportation immediately adopt clean fuel rules. The effective date for these rules was accelerated from January 1, 2028, to on or before January 1, 2027, and the overall law now takes effect in 2050 rather than the year 3000. Additionally, the list of eligible alternative fuels was expanded to include renewable electricity and industrial emissions, broadening the scope of the program.
