When global negotiations began on climate change, there was a clear divide between the developed and developing nations, the latter being supported by the poor countries. They rightly claimed that the rich nations had caused global warming and, hence, they needed to take action, as well as pay for the actions of, and damages suffered by, the developing countries. In 1992, there was thus a consensus to differentiate between the two categories, which was “converted into an operational firewall in the 1997 Kyoto Protocol, which assigned legally binding targets and timetables for reducing emissions to developed countries, backed up by rigorous rules for accounting, transparency, and compliance, while asking virtually nothing of developing countries.”
