Older vehicles pollute more and are a fraction of those on the road Beginning with model year 2004, California has implemented Low-Emission Vehicle (LEVII) tailpipe pollution standards for passenger vehicles. These older vehicles are responsible for 73% of all nitrogen oxide exhaust from passenger vehicles and 64% of reactive organic gases.

The bill responds to research conducted by UCS and The Greenlining Institute showing that while pre-2004 vehicles account for fewer than 20% of the cars on California’s roads, they emit nearly 75% of the smog-forming nitrogen oxides emissions.

Primarily, these have focused on the 2007 EPA regulations, which were the first step in the phase-in of diesel engine standards meant to cut particulate emissions by more than 80 percent and smog-forming nitrogen oxides (NO X ) emissions by 90 percent. <mic drop> So, is industry just full of it?

Dan Farber at Legal Planet recently posted on "Cars, Smog, and EPA" An excerpt: For the first 20 years of federal regulation, Congress set the NOx [nitrogen oxides] standards for new cars itself. That’s quite different from the standards for industrial pollution sources, which Congress has always delegated to EPA.
