The New Jersey legislature is debating new vehicle emission rules that would go into effect in 2006. The rules, based on the strict model in California, would include a requirement that 10 percent of the cars sold in the state produce no emissions. This would require manufacturers to sell approximately 45,000 zero-emission cars in the state by 2020, or earn credit for approaching that goal with other technologically advanced cars. The bill enjoys wide bipartisan support in the legislature.Both the federal and California programs set fleet-wide emission standards for new cars solely in participating states. By 2002, under the federal program, tailpipe emissions from cars would have to meet a standard of .097 grams per mile, whereas the California standard is .059 grams per mile. The federal government does not require the sales of zero-emission vehicles.
