improve vehicle efficiency and performance, and for other purposes. 

IN THE SENATE OF THE UNITED STATES 

MARCH 22, 2023 

Mr. GRASSLEY (for himself, Ms. KLOBUCHAR, Ms. ERNST, and Ms. 

DUCKWORTH) introduced the following bill; which was read twice and referred to the Committee on Environment and Public Works 

A BILL 

To promote low-carbon, high-octane fuels, to protect public 

health, and to improve vehicle efficiency and performance, and for other purposes. 

1 Be it enacted by the Senate and House of Representa2 tives of the United States of America in Congress assembled, 

3 SECTION 1. SHORT TITLE.

•S 944 IS

1 (1) continued increases in new automobile effi2 ciency are needed to improve consumer welfare and 

3 reduce carbon emissions; 

4 (2) the widespread availability of low-carbon, 

5 high-octane fuel will allow continued cost-effective 

6 improvements in automobile efficiency by enabling 

7 increased engine compression ratios; 

8 (3) high-octane automobiles and low-carbon 

9 fuels are readily available to consumers at little in10 cremental cost; 

11 (4) ethanol is a cost-effective and low-carbon 

12 octane enhancer; 

13 (5) the widespread adoption of climate-smart 

14 practices and precision technologies by United 

15 States corn producers over the past decade have fur16 ther reduced the carbon intensity of conventional 

17 ethanol; 

18 (6) on average, ethanol has been estimated to 

19 have lifecycle greenhouse gas emissions that are 46 

20 percent lower than average gasoline, with some corn 

21 ethanol achieving a 61-percent reduction compared 

22 to gasoline; and 

23 (7) ethanol has one of the highest blending oc24 tane values available in the marketplace.
