10.4.3 Effects on CO 2 Emissions
Figure 10.11 depicts CO 2 emissions from Japan in 2011 according to each scenario.
In the zero nuclear power scenario, CO 2 emissions increase because fossil fuel
power generation increases to compensate for shortages in the electricity market.
In the 20% nuclear power scenario, CO 2 emissions decrease by 7.68% compared
with the zero nuclear scenario. From the viewpoint of CO 2 emissions, nuclear power
is an important energy source, even if FIT is introduced.
10.4.4 Effects on Other Countries
The level of nuclear power generation in Japan has no significant effect on the GDP
of other countries. International fossil fuel prices, however, could increase negative
impacts on the Japanese economy. The CGE model used here explicitly includes
oil-producing countries, although political and economic strategies of such countries
are not considered.
10.5 Conclusion
This chapter assesses the importance of nuclear power generation in Japan from the
perspective of real GDP and CO 2 emissions. The assessment is conducted using a
multicountry multisector CGE model. The model is based on the GTAP-Power
database, which is an electricity-detailed extension of the GTAP 9 database. The
