What's the social cost of carbon?
Daniel Hall provides some additional thoughts:
1. Muse about uncertainty all you want, but ultimately you have to name your price.
2. This is higher than a lot of mainstream economists who work on this issue. Bill Nordhaus thinks the right value today is around $10 per ton of CO2 (see Table 5-4 of this publication); Billy Pizer at RFF thinks it is close to double this (ungated version here, see Table 5 (3 in gated version) suggesting the correct valuation is 82% higher). On the other hand Nic Stern estimates it should be $80 per ton of CO2.
3. Carbon prices in Europe are currently about 70% of this level (thanks partially to the weak dollar).
4. Carbon prices in the U.S. are short of this mark by about… oh, that’s right, $50.
