S. 4072 would have prohibited the use of fiscal 2024 funding to implement, enforce, or administer certain EPA rules on tailpipe emissions for vehicles. This includes the proposed May 2023 rule and the final March 2024 rule setting multipollutant emissions standards for light-duty and medium-duty vehicles for model years 2027 and beyond.
The Senate rejected S. 4072 on April 18, 2024 by a vote of 52 to 46 (Roll Call 142; a 60-vote majority was required for passage). We have assigned pluses to the yeas because the federal government has no constitutional authority to impose environmental regulations.
