The California Air Resources Board no longer includes low emission vehicles (LEVs) in its Buyer's Guide to Cleaner Cars. LEVs are 50 percent cleaner than cars certified to CARB's basic new car standard. However, as a result of progressively stricter manufacturer fleet average standards, emissions from LEVs are about the same as emissions from the average new car sold in California. Hence the omission.
