The Case for Carbon Pricing
When it comes to responding to the problem of anthropogenic climate change, the overwhelming preference among policy experts is for a system of carbon pricing. This is normally justified on the grounds that it maximizes the welfare of future generations. The objective of this chapter is to provide a philosophical defense of carbon pricing based instead on contractualist foundations. The central claim is that the negative externality of greenhouse gas emissions violates a reciprocity condition that is a central normative constraint in the system of cooperation in our society. A system of carbon taxation is recommended on the grounds that it addresses this externality problem more directly than any other policy alternative. The merits of such a regime are illustrated using the example of agricultural production and the carbon emissions associated with food supply.
