The second round of climate change talks in Bonn concluded a little after 5 in the evening on June 12. Twelve days of heated talks among representatives of 182 countries yielded very little: developed countries were not ready to do anything. After much wrangle, 37 developing countries agreed on how much emission the developed countries should reduce after the first commitment period of the Kyoto Protocol ends in 2012. The developed countries are listed in Annex I of the protocol.

Of two ad hoc working groups one focussed specifically on emissions reduction targets of Annex I countries for second and third commitment periods under the protocol, and the second on long-term actions of all countries to address and adapt to climate change.
