This book discusses federal standards for emissions of carbon monoxide from new motor vehicles. The first federal standards for emissions of carbon monoxide from new light- duty vehicles (LDV) or passenger cars, and light-duty trucks (LDT) including vans and other truck derivatives, took effect with the 1968 model year. The car and truck CO emission standards now in effect were first applied to all production models uniformly in 1983 and 1984, respectively. The car standard is 3.4 gram per mile and the truck standard is 10.0 grams per mile. Both represent 90% reductions, but from different starting points. The car standard is a 90% reduction from the 1970 model year level, which itself was a reduction from 1967, the last precontrol model year. The truck standard is a 90% reduction from 1969, the last precontrol model year for light-duty trucks. An additional feature of note is that the 10.0 g/mile standard is a 90% reduction only for the upper end of the LDT GVWR range, specifically those over 6000 pounds GVWR. For lighter LDT's the reduction from uncontrolled levels is less than 90%. The 3.4 and 10.0 standards meet the mandates of the Clean Air Act, and no further increases in stringency have been formally proposed by the United States Environmental Protection Agency (EPA). EPA has, however, mentioned the possibility of a tighter truck standard.
