WASHINGTON (AP) -- A Senate blueprint for tackling global warming would require power plants and vehicles to reduce their greenhouse gases by 70 percent. A chief sponsor said President Bush's approach of voluntary action will not meet the goal.
The proposal Thursday by Sens. John Warner, R-Va., and Joe Lieberman, a Connecticut independent, was seen as a compromise that could get the 60 votes needed to pass, perhaps next year.
''It is the tipping point ... a breakthrough,'' said Lieberman, who heads the Senate Environmental and Public Works subcommittee that will write the legislation. Warner is the panel's top Republican.
