Curbing emissions through (efficient) carbon liabilities: A note from a climate skeptic's perspective

We propose a new climate policy that is efficient, robust, and asks for payments proportional to realized climate damage. In each period, countries are made liable for their share of the responsibility in the current damage. Efficiency follows from countries' anticipations of climate change, hence of future payments. Robustness is achieved thanks to the introduction of a market for carbon liabilities. Rather than being based on the expected discounted sum of future marginal damage (as with a carbon tax or tradable emission permits) our proposal relies only on observed realized damage and on the well-documented emission history of countries.
