This research brief describes work documented in Fighting Air Pollution in Southern California by Scrapping Old Vehicles (MR-1256-PPIC/ICJ).

Excerpt: A California program to scrap old passenger cars and light-duty trucks (light-duty vehicles, or LDVs) would improve air quality in the greater Los Angeles area at a reasonable cost. Although presently unfunded and with its future in doubt, the program — if implemented — would help the state meet federal clean-air requirements for ozone in 2010 in the South Coast Air Basin, which includes all of Orange County and the urbanized portions of Los Angeles, Riverside, and San Bernardino Counties. Moreover, because the program appears more cost effective than alternatives for lowering LDV emissions, it — or an improved version — should be implemented.
