California is one step closer to being able to regulate greenhouse gas emissions from vehicles after a federal judge today rejected the auto industry’s challenge to a state law, the Los Angeles Times reports. The state still needs a waiver from the Environmental Protection Agency to implement its standards, which aim to reduce emissions by 30% by 2016.
Automakers claimed that federal standards trumped those passed by states in attempts to regulate fuel economy. California and 14 other states attempting to enforce laws stricter than federal standards have sued the EPA for a quicker decision on the waiver. The agency plans to rule by the end of the year. Meanwhile, the auto industry is expected to appeal.
