3 Background ADB's project which is named, Economics of Climate Change and Low Carbon Growth Strategies in Northeast Asia. ADB s website says one of the objectives of the project is to contribute to the regional and national debate on the economic costs and benefits of the actions on climate change mitigation. Mission Projecting abatement cost curves for China, Japan, Korea, and Mongolia. Projecting GHG emissions and mitigations for these four countries. The following results are the preliminary findings for the ADB study. 3

4 Background Outcomes GHG emissions and mitigations in 2020/30 Abatement cost curves in 2020/30 Calculation tool AIM/Enduse ACC tool Bottom-up modeling tool Detail technology selection framework Static analysis Mitigation options under a certain carbon price are selected 4

5 Technology D Technology E Technology F Technology G Abatement cost Technology A Technology B Technology C Methodology Key factor of the abatement cost curve analysis GHG abatement cost =Additional annual cost of technology/ Reduction of GHG GHG Reduction Annual cost of technology =Investment cost Capital recovery factor*+ O&M cost -Reduction of annual energy cost *Capital recovery factor = a(1+a) t /((1+a) t -1)= 1/Payback period a : discount rate t : lifetime Abatement cost curves provide technological mitigation potentials and technological implementation costs in each region. Be careful that abatement cost curves vary depending on the setting of: future energy price technology data (technology costs, discount rate, payback periods, etc) baseline scenario (socio-economic settings and energy service demand) 5

6 Methodology Data collection Activity amount (= driving force) Driving forces collected by consultants and researchers from four countries are used for our projection. Mitigation option (= technology) or more options are prepared. Simulation cases Baseline case: Technology frozen case Scenarios: Carbon price:,, USD/tCO2 Payback period: Short, Long Time horizon Base year: 8, Target year: 2020/30 6

19 Policy implications (1) Effective policy varies for the type of technologies Mitigation options are divided by abatement cost into some groups. The effective policy/action varies for each group. (2) Payback period has a large impact Only in Japan were there major changes in reduction potential depending on the payback period. (3) Measures for climate change enhance the stability of energy supply Especially in China, coal consumption increases tremendously without actions for climate change. On the other hand, in the event that actions are taken, coal consumption increase could be held to a small amount. 19

20 Policy implications (1) Effective policy varies for the type of technologies In following example, mitigation options are divided into three groups. Technologies with very HIGH (~) abatement cost Technologies with MIDDLE (0 ~ ) abatement cost Technologies with NEGATIVE abatement cost Abatement cost $US /tco2 $0US /tco2 Technologies with HIGH abatement cost Technologies with MIDDLE abatement cost Technologies with NEGATIVE abatement cost Reduction 20

22 Abatement Cost (US$/tCO2) Policy implications (2) Payback period has a large impact There are major changes in reduction potential depending on the payback period in Japan. 80 In 2020 Short Payback Period (high discount rate) Reduction (MtCO2) In 2020 Long Payback Period (Low discount rate)

23 Abatement Cost (US$/tCO2) Policy implications (2) Payback period has a large impact Measures for extending payback period are required to make reduction larger. 80 In 2020 Short Payback Period (high discount rate) Industrial Residential/Commercial Trasnport Reduction (MtCO2) In 2020 Long Payback Period (Low discount rate)

24 Mtoe Policy implications (3) Measures for climate change and energy security Energy consumption structure in 2020/30 in China. 6,000 5,000 4,000 3,000 2,000 1, , ,323 3, ,233 2,979 2,961 2, ,581 1,464 1,330 5,125 1,153 2,918 4,153 4,133 3, , ,006 1,796 1,645 Gas Base RF RF Oil Coal % 80% 60% 40% 20% 0% % 17% 24% 24% 24% 23% 21% 21% 21% 15% 17% 65% 64% Base RF 11% 15% 15% 18% 20% 25% 24% 12% 12% 13% 10% 10% 11% 53% 49% 48% 57% 48% 43% 43% RF Gas Oil Coal 24

25 Policy implications (3) Measures for climate change and energy security Energy consumption structure in 2020/30 in China. Coal consumption in China would increase tremendously in the event that no mitigation options were introduced. On the other hand, in the event that measures are taken, it was found that the increase from the base year could be held to a small amount. Measures for GHG emission reduction are thought to be an important policy from the standpoint of energy security as well. 25

26 Conclusion Emission Projection, MAC curve Emission/mitigation in 2020/2030 Abatement cost curve Policy Implications The effective policy will vary for technologies and countries. Policy for extending payback period is crucial for Japan. Actions for GHG emission reduction seem to be able to realize more stable energy security for China. 26
