Converging on a Climate Agreement

I read the blog post and it's an interesting idea, but could you tell us what the numbers are and how you arrived at them? Such as:

1. What are the developing countries considered?
2. What are the developed countries considered?
3. What are the current per capita emissions of the above countries?
4. What did you use for the population growth rates?

It just doesn't quite seem to add up from what I've seen considering the developing world currently has around 3 billion people and the developed world has around 1 billion and more population growth is projected to occur in the developing world rather than the developed world. In my unscientific analysis I considered the following as developed:

US
Canada
European Union
Japan
Australia
New Zealand

And the following as developing:
India
China
Mexico
Brazil
Russia

Which is really an incomplete list since many more countries emissions will be increasing over the next few decades. Thanks.

Jim, Thanks for your interest. We considered the following blocs/countries: (i) G8 (ie US, Canada, Japan, Russia, France, Germany, Italy, United Kingdom); (ii) non-G8 OECD countries except Mexico; (iii) China; (iv) India; (v) Brazil; (vi) Mexico; (vii) South Africa; (vii) Rest of World. This level of aggregation was chosen in part because business-as-usual projections are only available at a regional-aggregate level, and in part based on G8 committment to lead climate change mitigation efforts. We are currently performing an analysis
with a higher level of diaggregation.

It is also important to note that the 1600 billion ton target is based on a 50% probability of not exceeding 2C; a lower probability will require a more stringent target.

All current and projected emissions data comes from the US Energy Information Agency while population data comes from the
UN (World Populatin Prospects, 2006).
