Carbon Dioxide Emissions Reduction Potential in Japan’s Power SectorThis report commissioned by WWF Japan explores the potential for CO2 emissions reductions from Japan’s power sector.
In Japan, carbon dioxide (CO2) emissions associated with the energy transformation sectors account for over 30% of total CO2 emitted by the national economy. Substantial efforts to reduce the emissions in the power sector—which produces over half of energy transformation emissions—could have a significant impact on climate change mitigation in Japan.
The report compars the estimated quantitative impacts on CO2 emissions, and the overall costs to Japanese society, of providing energy services through two energy pathways: a "Business As Usual" (BAU) scenario, in which current trends in the Japanese economy and power sector continue, and a "Power Switch" (PS) scenario, in which more aggressive transitions to non-fossil and low-carbon fuels are carried out in the Japanese power sector, accompanied by complementary aggressive implementation of energy efficiency measures geared to reduce electricity requirements.
