Overview
- The EPA, which unveiled the plan Thursday, would push compliance for light- and medium-duty vehicles to the 2029 model year.
- Citing weaker electric-vehicle sales, the agency says automakers cannot meet the tougher limits without a faster shift to EVs.
- Reuters reports the delay would trim near-term compliance costs for carmakers by about $1.7 billion.
- The slower phase-in would cut fewer greenhouse gases and smog-forming pollutants in the next few years than the original schedule.
- This is a proposal, not a final rule, and it now moves into a public comment process before any changes take effect.
