That doesn’t make the ”CO2 outsourcing” claim untrue. For the 1990-2008 period, the paper[1] cited as the source for the graph in question notes:
> Collectively, the net CO2 emission reduction of ∼2% (0.3 Gt CO2) in Annex B countries from 1990 to 2008 is much smaller than the additional net emission transfer of 1.2 Gt CO2 from non-Annex B to Annex B countries (equivalent to subtracting the net emission transfers in 2008 from 1990 in Fig. 2).
The situation may have improved since then[2], but already in 2008, China’s consumption share of its own emissions was 80%. This figure in itself neither proves or disproves whether developed nations have outsourced their emissions.
