Although reasonable people may disagree on what equity and justice may require of any national ghg emission reduction commitment, there are only a few considerations that are arguably morally relevant to national climate targets. This entry will end with the identification of a few equity frameworks that have received serious attention in the international community. It is important to stress, however, that although there is some legitimate disagreement about which of these formats to follow in international negotiations, almost all national emissions reductions commitments of large emitting countries fail to pass any reasonable ethical scrutiny. In discussing equity and the distributive justice of national commitments, the relevant criteria for being treated differently that have been recognized by serious participants in the debate about equity include: (A) per capita considerations, (B) historical considerations, (C) luxury versus necessity emissions, (D) economic capacity of nations for reductions, (E) levels of economic development, and (E) and combinations of these factors.
The fact that reasonable people may disagree about the importance of each one of these criteria does not mean that anything goes as a matter of ethics and justice. In addition, the positions actually been taken by nations on these issues in the negotiations utterly fail any reasonable ethical scrutiny. For this reason, concerned citizens of the world should focus heavily on the obvious injustice of national positions on these issues rather than worrying about what perfect justice requires.
In addition, in all probability, a global framework for equity would include some forward looking considerations including per capita considerations and backward looking considerations such as historical responsibility from a specific date, modified by certain economic considerations including economic ability to respond rapidly and perhaps differences between necessity emissions and luxury emissions.
We would stress, it is not as necessary to get immediate agreement on the final framework as it is to achieve a wider understanding of the utter failure of national commitments thus far to deal with the equity and justice issues. Along this line each nation should be asked to answer a series of questions about their commitments which include:
A. What specifically is the quantitative relevance of your emission reduction commitment to a global ghg emissions budget to keep warming below the 2°C warming target? In other words how does your emissions reduction commitment in combination with others achieve an acceptable ghg atmospheric concentration that limits warming to 20 C.
B. What is the atmospheric ghg concentration level that your target in combination with others is aiming to achieve?
C. How specifically does your national commitment take into consideration your nation’s undeniable obligation under the UNFCCC to base your national climate change policy on the basis of “equity”? How have you operationalized equity?
D. What part of your target was based upon “equity”?
