Japanese climate policy scenarios toward 2050 Background: - UK, Germany, France, Sweden,,,,: Long term climate strategies, reducing GHGs drastically toward 2050. Are those the paths we should follow? - In UNFCCC and Japan: Beyond Kyoto Issue started. Quantitative base required. Goal: - To explore the possible paths to low carbon society in Japan toward 2050. - Major output: GHG emission scenarios - Various related research works. - How should we set policy target? (stabilization target, international burden sharing, sustainable development,,) - What technological and societal changes need to be introduced and how? (Options, Policy and Measures) - What implications these scenarios pose to future Japanese economy and society? (Evaluation of policies)
