EPA Administrator Lisa Jackson told reporters that a formal "endangerment finding," which would trigger federal regulations on greenhouse gas emissions, probably would "happen in the next months."
A formal endangerment finding would obligate the agency to regulate greenhouse gas pollution under the Clean Air Act - even if Congress doesn't pass a final climate-change bill.
President Obama and Jackson have said they would prefer that Congress - rather than the EPA - take the lead in implementing new greenhouse gas limits. Businesses and energy industry leaders also have largely favored congressional action over EPA-imposed limits, because they believe lawmakers are better positioned to combine economic safeguards with any new carbon cap.
"Legislation is so important, because it will combine the most efficient, most economy-wide, least costly (and) least disruptive way to deal with carbon dioxide pollution," Jackson said. "We get further faster without top-down regulation."
But Jackson insisted the EPA would continue on a path that began when the Supreme Court ruled in 2007 that greenhouse gases qualified as pollutants and could be regulated if the government determined they threatened the public.
