An excellent graphic from Roger Pielke, Jr. [the GHG emissions of Haiti and Somalia are the only ones consistent with an 80% reduction from total-world levels].
Bottom line? No country, save Haiti and Somalia, is currently producing emissions at a level even remotely consistent with levels consistent with an 80% reduction in the world’s totals. Hence, all of the finger pointing and debates in political negotiations are based on relative hypocrisy (“We’re doing relatively less bad that you are!”) or faith-based assumptions in the efficacy of future policies (“Our targets are more aggressive than yours!”).
There remains huge hurdles to achieving emissions reductions of the sort called for in current political debate. Until we see evidence of it actually occurring, somewhere, we should be very cautious about picking what policies will ultimately achieve results. Instead, we should try a diversity of approaches and see what works.
