The Ethics of Emissions Trading

This article defends three ethical arguments against emissions trading. The first argument alleges that emissions trading is morally objectionable, because it 'commodifies' the atmosphere. The second argument involves various objections to attaching prices to units of emissions - loosely speaking, the objection is to pricing that which is priceless or should not be priced. The third argument turns on the idea that if a large cut in emissions is to be made by society overall, everyone should 'do their bit' by making a particular kind of sacrifice rather than paying others to do it instead. Some general conclusions concern the limitations of confining the analysis to idealised emissions trading, the difficulty in separating 'economistic' thinking about policy delivery from policy choice and the need to focus questions of justice on consumers rather than on producers.
