Each of the major philosophical arguments about the proper shape of climate policy suffers from basic flaws. Some suffer from idiosyncratic, internal logical problems but the focus here has been on systematic problems common to all of the arguments. By thinking of the problem as part of the “ethics of climate change,” people ignore the fact that climate change policy is just part of a web of policies, including policies to help the poor and policies concerning ownership of resources. They operate with climate change blinders. Removing these blinders shows that the recommendations from climate ethics do not follow from the arguments.
Moreover, the arguments tend to produce conclusions that are not within the realm of feasibility. It is sometimes good for ethical arguments to be aspirational, to ask us to stretch beyond what we think we can do. But suggestions that will simply never happen are not helpful, particularly when we face an immediate global threat.
1. Gardiner’s list of the theories of justice that are most applicable to climate change is made up of procedural justice, distributive justice, and corrective justice. See Gardiner, “Climate Justice,” in The Oxford Handbook of Climate Justice and Society, eds. John S. Dryzek, Richard B. Norgaard, and David
Schlosberg (Oxford: Oxford University Press, 2011), 310. I do not discuss procedural justice and separate equality from distributive justice. Gardiner refers to theories of equality separately on p. 315.

Shue unfortunately injects concerns about animal cruelty via feedlots into the discussion, arguably confounding the appeal of the pure distributive argument with the appeal of concerns about the treatment of animals.

- 9. An additional requirement for applying any theory of justice to climate change is some form of cosmopolitanism. We have to believe that people who live in one nation owe duties to people who live in other nations, or perhaps nations owe duties to other nations or to people in other nations. While this view is contested, I will take it as correct.
- 10. For example, the Millennium Challenge Corporation has very specific governance requirements for nations to qualify for aid in order to ensure that the money is well spent.

This statement comes at the beginning of a section of his paper on responsibility for past emissions but it not clear whether Gardiner believes the statement to be supported only by a theory of responsibility or whether the consensus view is supported more generally, including by theories of distributive justice. In the next paragraph he notes a lack of consensus on backward-looking considerations, which is the core issue of responsibility.

The numbers were computed by taking the difference between cumulative emissions for a country divided by the total number of lives in that country during the time period and cumulative global emissions divided by total lives during the same time period. This gives the excess per person emissions. This amount was multiplied by the total lives in the country and by the carbon price. Calculations are available from the author. The carbon price is not adjusted for time. The reason is that the carbon price should increase over time at roughly a constant rate. This means that the price in a prior year should be the current price discounted by that constant rate. But the amount would have been owed in that prior year so the amount owed today is the future value of that amount. Taking discounted values and future values at the same rate offsets, we can simply use the current price and add up the total amounts.

- 37. A global cap-and-trade system would generate emissions reductions, so the numbers would not exactly reflect what would happen but the reductions would very likely be modest in the short run. So this calculation gives a reasonable estimate of the transfers that would occur in the early years of such a program.
