Climate talks open as Obama EPA move boosts effort
Delegates at the Copenhagen climate summit welcomed the White House plan to regulate greenhouse gases under the clean air law, while urging stronger U.S. and Chinese commitments. Leaders and observers stress finance for poorer nations and robust post Kyoto pledges as 15,000 delegates gather amid protests and high stakes. The talks aim to replace Kyoto, with the EU seeking 20 percent cuts by 2020 and up to 30 percent if others join. Obama proposes a roughly 17 percent reduction by 2020 from 2005 levels, contingent on Congress action.
