What share of the growth in global greenhouse gas emissions is due to consumption in rich nations compared to poor nations?

Since 1990 emissions in Annex B countries (those with emission constraints) have largely stabilized, while emissions in non-Annex B countries (developing countries) have increased substantially (e.g., Figure 2, http://edgar.jrc.ec.europa.eu/background.php). Several recent studies indicate that it is likely that a significant share of the growth in non-Annex B emissions is due to consumption in Annex B countries (e.g., US, http://pubs.acs.org/doi/abs/10.1021/es0629110; UK, http://randd.defra.gov.uk/Document.aspx?Document=EV02033_7331_FRP.pdf; China, http://www.agu.org/pubs/crossref/2009/2008GL036540.shtml). This is due to a shift of Annex B countries towards services with a corresponding increase in imports. Despite the availability of data and methods no one has undertaken a comprehensive study of how consumption (as opposed to production) acts as a driver for greenhouse gas emission increases over time. A key question for climate negotiations is how much of the emissions growth in non-Annex B countries is due to consumption in Annex B countries. There is a need for both retrospective studies looking into historical developments as well as studies looking at how this may change as Annex B countries begin more aggressive mitigation after 2012.
