The social cost of carbon and inequality

The social cost of carbon is a monetary metric for the damage caused by the emission of an additional tonne of CO2. Previous literature has shown that accounting for inequality between countries significantly influences the social cost of carbon, but mostly omits heterogeneity below the national level. Using a model that features heterogeneity both between and within countries, this column demonstrates that climate and distributional policy can generally not be separated. In particular, it shows that a higher social cost of carbon may be called for globally under realistic expectations of existing inequality.
China has a grand carbon neutrality target but where is the plan?

China’s new long-term targets, to reach peak emissions before 2030 and achieve carbon neutrality by 2060, are yet to be matched with a consistent short-term action plan.
