| Outline of Research at the Start |
To investigate how transport electrification would contribute to climate change mitigation, this research aims to develop an integrated modeling methodology to couple transport model, economic model, and climate model, with the objective of helping shape the policy agenda for electrified transport.
|
| Outline of Final Research Achievements |
A global transport model coupled with an economic model and climate model was employed to investigate the role of transport electrification in global climate change mitigation. Although the direct CO2 emissions from transport sector can be reduced significantly by transport electrification, the market diffusion of electric vehicles without implementing ambitious penetration of renewable energy in the power sector leads to the result of increasing emissions from energy supply. In addition, the carbon price for achieving the target of a 2°C global temperature rise decreased due to the undertaking of an ambitious transport electrification policy. The GDP and welfare loss rate associated with pricing carbon can be thereby mitigated significantly. EV policy can help to relieve the negative impacts of climate change mitigation efforts on the macroeconomy.

| Academic Significance and Societal Importance of the Research Achievements |
本研究は、運輸部門の電化が将来の世界全体の温室効果ガス排出量や気候変動にどのような影響を与えるか、また、排出削減や気候変動緩和のためにはどのような政策や戦略が必要かを明らかにした。今回の研究は気候変動緩和に対する運輸部門の電化の貢献や、低炭素移行に向けた潜在的な解決策としてのEVの役割を過小評価するものではない。むしろ、より調和のとれた包括的な政策を策定するためには、運輸部門の電化と電力部門の相互作用が必要であることを強調している。運輸部門の電化をカーボンプライシングなどのエネルギー政策と組み合わせることで、運輸部門からの排出削減と社会全体の低炭素化の同時達成をできる可能性がある。
