Key climate change talks kicked off in Germany today. They are one of the last meetings before the decisive end-of-the-year talks are held in Mexico. Delegations from most of the 194 participating nations begin the five-day negotiating session in the German city of Bonn.
Christiana Figueres, president of the talks, says the industrial countries must lift their emissions reduction pledges, insisting that rich countries slash emissions by 25 to 40 percent by 2020.
The U.N. negotiations aim to reach a deal to succeed the 1997 Kyoto Protocol. That agreement called on a list of industrial countries to cut emissions by a total 5 percent by 2012 from 1990 levels.
