Comparing different approaches to tackle the challenges of global carbon pricing

Climate change mitigation faces two main policy challenges: the need for global cooperation to tackle the collective action problem and the need to share the burden of global carbon pricing fair way following the principle of common but differentiated responsibility (CBRD). In this paper we explore the best ways to incentivize regions to reduce their CO2 emissions while minimizing the welfare losses for low-income countries using simulations with a recursive dynamic computable general equilibrium (CGE) model.
