NOTES
All Countries
Light trucks are vehicles of about 3,856 kg or less gross vehicle
weight rating (GVWR). For United States and Canada, the exact definition
is 8,500 pounds or less, and, for the time period of this table, there are four
and two categories of light trucks, respectively, within the range of zero through
8,500 pounds.
Canada
Loaded vehicle weight (LVW): See Appendix B under the United States for definition.
From September 1, 1997, Canadian standards are harmonized with U.S. standards by regulation, for all classes of on-road vehicles.
Passenger cars and light trucks: For cars (light-duty vehicles) and light trucks (light-duty trucks, LDT), Canadian 1996 regulated standards were technically equivalent to those of the United States for 1988 model year vehicles, but in practice, manufacturers and importers provided vehicles meeting U.S. 1996 standards.
Mexico
Particulates: No regulations are in effect for particulates for these vehicles.
United States
Useful life: The life over which the standards must be met. See Appendix B for a more complete definition.
Measurement units: The U.S. regulations are written in units of grams per mile. This table has converted the U.S. regulations to grams per kilometer. A simple conversion back to U.S. measures will result in rounding error and/or an incorrect level of precision in some cases. Appendix D provides the original U.S. measures.
Coverage: This table is a simplification of the U.S. emissions standards for passenger cars and light trucks.
Implementation schedules: Schedules are summarized in Appendix B. The standards were phased in over several years.
Passenger cars and light trucks: Data are for gasoline-fueled vehicles only. See Appendix B for the differences for diesel fueled vehicles.
Light trucks: There are four categories of light trucks. The regulations presented here are for the LDT2 category, which has a GVWR up to 2,722 kg (ie., 6,000 pounds or less) and a LVW of 1701 kg to 2,608 kg (i.e., 3,751 pounds through 5,750 pounds). (GVWR and LVR are defined in Appendix B.) In 1996, LDT2s accounted for more than 60 percent of the sales of new light trucks.
