Carbon policy is an important market design problem that has been put off for too long. On 31 January-1 February there will be a two-day conference in Washington on Carbon Market Design: Issues and Opportunities. The conference is open to the public, but registration is required and space is limited. This modafinilsmart should be an excellent event. For background on some of the broader issues of climate policy from a market design perspective I recommend you look at the Global Energy Policy Center.
