While numerous studies find that deep-saline sandstone aquifers in the United States could store many decades worth of the nation's current annual CO2 emissions, the likely cost of this storage (i.e. the cost of storage only and not capture and transport costs) has been harder to constrain. We...

The approach used to model technological change in a climate policy model is a critical determinant of its results in terms of the time path of CO2 prices and costs required to achieve various emission reduction goals. We provide an overview of the different approaches used in the literature,...

Climate policymaking faces twin challenges of carbon leakage and public sector revenue requirements. A large literature advocates the use of CO2 pricing and recycling the revenues to lower distorting taxes as a way to minimize costs. In this paper, we explore the implications of labor tax...
