The EPA’s April 12, 2023 proposal was described as potentially avoiding nearly 10 billion tons of carbon dioxide emissions through 2055 and saving the average consumer about $12,000 over a light-duty vehicle’s lifetime. Those were projections for the proposed rule, not the final rule adopted in 2024.
The EPA announced on April 12, 2023 that proposed vehicle standards could avoid nearly 10 billion tons of carbon dioxide emissions through 2055 and save consumers an average of $12,000 over a vehicle’s lifetime.

Key Evidence
Roll Call’s April 12, 2023 report attributes both projections to the EPA’s proposed vehicle standards: nearly 10 billion tons of avoided carbon dioxide emissions through 2055 and $12,000 in lifetime savings for the average consumer.
The figures were estimates tied to the proposal, not guarantees or measured results. Supporting coverage from Government Fleet and Thomasnet repeated the emissions projection, while the Resources for the Future analysis examined the consumer effects of the proposed standards.
The EPA later finalized a different version of the standards on March 20, 2024. The agency projected that the final rule would avoid 7.2 billion tons of carbon dioxide emissions through 2055, so the later figure should not be substituted for the original April 2023 proposal when checking this historical claim.
What the Evidence Shows
Roll Call reported on April 12, 2023 that the Environmental Protection Agency had proposed stricter vehicle emissions standards and that the agency estimated the proposal could avoid nearly 10 billion tons of carbon dioxide emissions through 2055 while saving the average consumer $12,000 over a light-duty vehicle’s lifetime.
