Fact Sheet: SAFE Vehicles Rule

The final rule will increase stringency of CAFE and CO2 emissions standards by 1.5% each year through model year 2026, as compared with the CO2 standards issued in 2012, which would have required increases of about 5% per year.  

Overall Impact

Lower costs, thousands of lives saved, and minimal impact to fuel consumption and the environment. 

  • $200 billion reduction in total costs over the lifetimes of vehicles through MY 2029, including the value of increased safety
  • $100 billion reduction in regulatory costs 
  • $1,400 reduction of total consumer cost of ownership per new vehicle
  • More than $1,000 reduction in sales price per new vehicle  
  • 2.7 million additional new vehicles sold (because new vehicles are more affordable)


  • 3,300 fewer crash fatalities
  • 46,000 fewer hospitalizations after serious crashes projected over the lifetimes of vehicles built through MY 2029
  • 397,000 fewer injuries 
  • 1.8 million fewer vehicles damaged in crashes


  • All new vehicles will continue to be subject to the strict pollution standards of the Clean Air Act and new vehicles will be subject to higher pollution standards than the older vehicles that will be retired because of this rule 

  • 40.4 mpg projected overall industry average required fuel economy in MY 2026, compared to 46.7 mpg projected requirement under the 2012 standards
