Auto makers regularly cite the "patchwork" of safety, fuel-efficiency, and emissions regulations in North America as a hindrance that makes doing business difficult and raises costs.

There's no doubt they would much prefer a scenario where they could resist progress in these areas by unleashing their lawyers on a single regulator. :D

(OK, perhaps that's a bit too cynical...)

Quote:

New Mexico is now the 13th state to do so, which is really starting to complicate things for carmakers. Other states that have enacted the law, which is allowed under a special provision of the Clean Air Act include: Maine, California, Vermont, Rhode Island, Massachusetts, Connecticut, New York, New Jersey, Pennsylvania, Maryland, Washington and Oregon. Arizona, Colorado and Florida are in the process of enacting the law.

The Clean Cars program involves three key elements:

Stricter standards for traditional air pollutants for LEV II vehicles
A fleet-wide standard set for reducing vehicle greenhouse gas emissions
Zero emission vehicles program that drives advanced vehicle research and production.
