Major policy measures ■More nuclear power ■ “ Voluntary Action Plan ” by Keidanren ◆ Keidanren: Japan Federation of Economic Organizations ■Enhanced application of energy saving law (more appliances) ■National announcements to arouse people to reduce emission from daily life ■(No Emission Trading and Environmental Tax – under discussion)  Lack of an effective measure

Last study ■BAU: follows IEEJ2002 ■National Alternative: ◆ less nuclear, more renewables and energy efficient technologies ■Regional Alternative: North East Asian regional cooperation ◆ Pipeline oil and gas import, electricity import ◆ Oil Refining on Commission with China ◆ Regional Cooperation in Nuclear (Funding) ◆ Cooperation in Energy Efficiency and Renewables (Funding  early implementation of technologies)

Governance Design Laboratory © 2007 Governance Design Laboratory. All right reserved. Regional Alternative (1) ■Pipeline Oil Import from Siberia ◆ 1 million bbl/day, from 2010, $1.5/bbl higher price ■Pipeline Gas Import from Sakhalin ◆ 6 million ton from 2015, price is set $3/GJ in 2005 (rise at the rate of crude oil price) ■Electricity import from Sakhalin ◆ 2GW from 2012, 4GW from 2014, 5 USC/kWh (fueled by natural gas)

Governance Design Laboratory © 2007 Governance Design Laboratory. All right reserved. Regional Alternative (2) ■Oil Refining on Commission with China ◆ 10,000 bbl/day in 2004, increase to 60,000 bbl/day in 2010, remain same until 2015, finish in 2016 ◆ Commission fee is set $3/bbl ■Regional Cooperation in Nuclear ◆ Funds ●Nuclear Research: 8 million USD from 2007 to 2015, raise to 100 million USD until 2025, raise to 300 million USD by 2030 ●Waste Agreement: 8 million USD from 2006 to 2015, 25 million USD from 2016 to 2030 ■Cooperation in Energy Efficiency and Renewables ◆ Funds ●Energy Efficiency: cost $1/HH since 2006 (approx. 50 million USD/year), Renewables: cost 50 million USD/year to Elec. Gen. ◆ Effect ●2 years earlier implementation of technologies in energy efficiency and renewables ●Cost reduction by 10%
