Reading the Data on Developing Countries
• Rapid growth in energy use and emissions
• China is the major player, both in rate and scale:
– 618 GW installed capacity in 2006
– 106 GW newly installed
source: J. Kejun (2007)
• Have modeling scenarios caught up?
• What are the implications for global stabilization goals?

Conclusions
• There is considerable uncertainty about future growth…
• … but, the scenario shown here is plausible, consistent with current observations and historical experience
• If developing countries continue to grow along this baseline path, aggressive stabilization targets quickly become impossible to meet (without overshoot)
• Annex B countries must find a way to engage China
