Specific countries will end up paying more for Climate Change than others
but the projected costs are not fair for all.

"...India is the country likely to bear the highest cost per tonne of CO2, at a mid-range estimate of US$86. The US is in second place at US$48, followed by Saudi Arabia, Brazil, and China. The estimates themselves are uncertain, but the rankings, the authors write, are not: they stay pretty much the same regardless of where in the range you look.
The per-country costs are largely unfair: the countries that contribute the least to global carbon emissions stand to pay some of the higher costs. India, for instance, is set to pay around four times its fair share of the cost relative to its emissions. China, on the other hand, is the exact opposite.
