6. Description of content:  Proposed rule - The Environmental Protec tion Agency (EPA) is 
proposing to  revise the greenhouse gas (GHG) emissions standards for light -duty vehicles 
for 2023 and later model years to make the standards more stringent. On 20 January 
2021, President Biden issued Executive Order 13990 "Protecting Public Health and the 
Environment and Restoring Science To Tackle the Climate Crisis" directing EPA to consider 
whether to propose suspending, revising, or rescinding the standards previously revised 
under the "The Safer Affordable Fuel -Efficient (SAFE) Ve hicles Rule for Model Years 2021 -
2026 Passenger Cars and Light Trucks," promulgated in April 2020. The SAFE rule 
significantly weakened the standards established in 2012, which in part set GHG 
standards for model years 2021 -25. EPA believes that in light o f the significant 
contribution of light -duty vehicles to transportation sector GHG emissions, standards 
more stringent than those relaxed in the SAFE rule are appropriate under the Clean Air 
Act. EPA is proposing to revise the GHG standards to be more stri ngent than the SAFE 
rule standards in each model year from 2023 through 2026. EPA is also proposing to 
include several flexibilities to incentivize the production and sale of vehicles with zero and 
near-zero emissions technology to reduce compliance costs and to address the lead time 
of the proposed standards. In addition, EPA is proposing some technical amendments to 
clarify and streamline our regulations. Compliance with the proposed standards would be 
feasible at reasonable costs to manufacturers. The pr oposed revised standards would 
result in significant benefits for public health and welfare, primarily through substantial 
reductions in both GHG emissions and fuel consumption and associated fuel costs paid by 
drivers, and the benefits of the proposed sta ndards would be far in excess of costs.  G/TBT/N/USA/1760
