Chakravarty et al. have proposed an original burden-sharing scheme for global CO2 emission reduction efforts whose underlying theme of ÒEat the RichÓ (or as it turns out, rather, the middle-class) might resonate well in current times of economic crises. The core methodological elements of Chakravarty et al.'s proposal include the construction of a current global income distribution curve, which is assumed to remain constant over time. The authors then boldly assume a constant elasticity of CO2 emissions with respect to income, irrespective of country, development status, or time to determine each country's share of Òhigh emitters.Ó
