A U.S. federal judge has rejected an automakers'
lawsuit against California, saying the state has the authority to
regulate greenhouse gas emissions from vehicles.
The ruling by U.S. District Court Judge Anthony Ishii clears one
of the hurdles in California's effort to regulate tailpipe emissions
from cars, trucks and sports utility vehicles.
Automakers sued the state over the tailpipe standards it approved
The new standards would force automakers to build cars and light
trucks that produce about 30 per cent less greenhouse gases by 2016.
However, the state still needs a waiver from the U.S.
Environmental Protection Agency to begin implementing the program.
The EPA has not yet issued a decision.
