General Motors sued California on Friday to overturn the state’s zero-emissions-vehicle mandate, which requires automakers to produce a limited number of ZEV vehicles in 2003 and increase the number in following years. The lawsuit claims that the California Air Resources Board didn’t take seriously automakers’ concerns about the mandate’s cost or consider a reasonable alternative to the plan. A big reason for GM’s yelps: New York, Massachusetts, and Vermont are set to follow the California rule, and the four states together account for about 18 percent of the U.S. auto market. Other automakers have declined to join the suit.
