Abstract

I examine the environmental and economic impacts of optimal and second-best climate policies in a macroeconomic model. The model is calibrated to match the dynamics of energy use and energy prices observed in aggregate data. The data suggest that improvements in energy efficiency and substitution between different fossil sources are both important margins for reducing emissions. Compared with carbon taxes, therefore, clean energy subsidies and clean energy intensity standards require much greater reductions in consumption in order to achieve a fixed emissions reduction target. Emissions intensity standards, however, are only mildly more costly than carbon taxes.
