| Summary/Abstract |
In this paper we consider future options for Japanese energy and climate policy. We assess the economic and environmental impacts of changing the share of electricity generated by nuclear power and varying the mid-term GHG targets. The quantitative approach we use is based on the global macro-econometric E3MG model.
Our analysis reveals that the cost of denuclearisation to Japanese GDP is close to zero, and for employment the impact is slightly positive. Our results also show a double-dividend effect if (revenue-neutral) carbon taxes are levied in order to meet the GHG reduction targets, and this double-dividend effect is largest in the scenarios without nuclear power. However, our analysis suggests that a very high carbon tax rate would have to be imposed in order to achieve a 25% reduction in GHG emissions in 2020 (compared to 1990 levels) while simultaneously phasing out nuclear power.
