Fig. 4.

The development of the net emission transfer via international trade between Annex B and non-Annex B countries for six aggregated regions from 1990 to 2008 using the TSTRD method. Net emission transfers represent the emissions from the production of exports (SI Appendix, Fig. S4) minus the emissions in other countries from the production of imports (SI Appendix, Fig. S5). The colored areas are the emission transfers for each region, the solid black line is the net emission transfers for each region with the rest of the world, and the dashed black line is the net emission transfers for the Annex B with non-Annex B countries (comparable with Fig. 2).
