One challenges the elitism that is implicit in overriding democracy: according to the utilitarian calculus the government should value the interests of the future far more highly than most voters would do. Indeed, if we are guilty of radically undervaluing the future, then this neglect applies not just to carbon emissions, but to all the other ways in which we could help the world of the future. The government should force us to save far more than we do, perhaps by subsidising bequests instead of taxing them - in the utilitarian calculus there is nothing special about curbing global warming as a means of benefiting the future. Are we radically neglecting the future by not saving enough?
…Personally, I doubt whether the utilitarian calculus is the right ethical framework in which to think about global warming. It gives us numerical answers, but it just does not feel as though the calculus captures my concerns. …Is there an ethical basis for being concerned about global warming that does not depend upon the notion that quite generally we are radically negligent about future people? I think that there is, but this concern depends upon a rights-based notion of ethics rather than on utilitarianism. Most professional economists will at this point stop reading because they will think that rights are a quagmire. But here goes.
Natural assets such as biodiversity, and natural liabilities, such as carbon, are not owned by the current generation, because we did not create them. We have them because previous generations passed them on to us, and we are obliged to do the same. If we deplete natural assets, or run up natural liabilities, we have an obligation to compensate future generations in some other way…Ultimately, in a democracy our policy decision rules must rest on ethical principles that are widely shared by citizens. I suspect that most people feel that they should reduce carbon emissions, but the key issue is why? Is their motivation better captured by the utilitarian calculus used by economists, or by a sense of custodial obligation towards our natural legacy, of which carbon is but one instance?
