SAN FRANCISCO, California (Reuters) -- California released its final plan Friday to reduce greenhouse gas emissions from cars and trucks by about 30 percent by requiring hundreds of dollars in technology to control air pollution in new cars.
The plan is the first of its kind among U.S. states. It has been closely tracked by car makers as California accounts for nearly 13 percent of the U.S. auto market and because other states may adopt similar rules.
Auto makers have said they may sue to block the plan.
