This article test, whether John Rawls´ Theory of Justice is still relevant in a warming climate.

It can be argued that economic growth in developed countries benefits people in developing countries, as we can afford to give more development aid. I argue, however, that this has not been large enough to compensate for its the negative side effects, most notably that of a warming climate. Furthermore, the costs of current carbon fueled economic growth favoring present generations in the developed countries will mainly be paid by future generations of the poor in developing countries.
