There are also some reports on bilateral talks between the US and China at Joe Romm’s climate progress blog which may be worth checking out.

Prof Stephen Howes also recently gave a seminar on post-Kyoto proposals from China at http://rspas.anu.edu.au/rmap/seminars.php .

The Chinese carbon budget proposals are probably less generous to high per-capita emitters that contraction and convergence approaches. In his talk Garnaut noted that “at some time during this century, I suggested 2050 but we can discuss the appropriate date, there will need to be a convergence on equal per-capita emissions”. The suggestion from Garnaut and others that a 25% reduction by 2020 on 2000 levels for Australia would be consistent with a stabilisation target of 450 ppm CO2-e is partially based on a convergence date of 2050. A 2050 convergence date would be considered by many low per-capita emitters as quite generous to high per-capita emitters. For this reason, a 25% reduction by Australia would not be considered by developing countries to be sufficient.
