The 17th Conference of Parties to the United Nations Framework Convention on Climate Change (COP17) opened in Durban, South Africa, on Monday, with 195 countries taking part. The focus of discussions is on what to do after the 1997 Kyoto Protocol, the only binding climate agreement at present, expires at the end of 2012.

The treaty imposes greenhouse gas emission cuts on developed countries, with the commitment period set from 2008 to 2012, among other provisions.

COP17 continues through Dec. 9, but it is not expected to produce a long-term comprehensive framework requiring both developed and developing countries to cut emissions. Among the developing countries, however, there are calls for revising the protocol to create a second commitment period for reduction efforts by developed countries that are party to it.
