Based on model year 2008 NMOG certification data for vehicles sold in California, 22% of new vehicles are certified as LEV, 55% as ULEV, and 22% as SULEV. Light-duty passenger cars and trucks are responsible for a major fraction of ozone- forming emissions: NO x (15% of California emissions), CO (42%), and ROG (21%).
