                                 A BILL


 
To promote low-carbon, high-octane fuels, to protect public health, and 
 to improve vehicle efficiency and performance, 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 ``Next Generation Fuels Act of 2023''.

SEC. 2. FINDINGS.

    Congress finds that--
            (1) continued increases in new automobile efficiency are 
        needed to improve consumer welfare and reduce carbon emissions;
            (2) the widespread availability of low-carbon, high-octane 
        fuel will allow continued cost-effective improvements in 
        automobile efficiency by enabling increased engine compression 
        ratios;
            (3) high-octane automobiles and low-carbon fuels are 
        readily available to consumers at little incremental cost;
            (4) ethanol is a cost-effective and low-carbon octane 
        enhancer;
            (5) the widespread adoption of climate-smart practices and 
        precision technologies by United States corn producers over the 
        past decade have further reduced the carbon intensity of 
        conventional ethanol;
            (6) on average, ethanol has been estimated to have 
        lifecycle greenhouse gas emissions that are 46 percent lower 
        than average gasoline, with some corn ethanol achieving a 61-
        percent reduction compared to gasoline; and
            (7) ethanol has one of the highest blending octane values 
        available in the marketplace.

SEC. 3. HIGH-OCTANE VEHICLES.

    Title II of the Clean Air Act (42 U.S.C. 7521 et seq.) is amended 
by adding at the end the following:
