マレーシアの乗用車を対象に、ガソリン車（ICEV）、ハイブリッド車（HEV）、電気自動車（EV）の運用エネルギーとCO2排出量を比較する簡易モデルを構築。HEVとEVはICEV比で年間CO2排出をそれぞれ38.69%、45.96%削減するが、EVの性能は電源構成に強く依存する。シナリオ分析から、電化だけでは不十分で、グリッドの脱炭素化と充電インフラの整備が不可欠と指摘。バランスのとれた移行戦略を提言。
English
This study develops a simplified comparative model for operational energy use and CO2 emissions of gasoline ICEVs, HEVs, and EVs under Malaysian conditions. HEVs and EVs reduce annual operational CO2 by 38.69% and 45.96% respectively, though EV performance heavily depends on the electricity generation mix. Scenario analysis indicates that electrification alone cannot achieve rapid decarbonisation without grid decarbonisation, aggressive adoption, and infrastructure. A balanced transition strategy combining electrification, efficiency improvements, and power-sector decarbonisation is recommended.

📄 Abstract（原文）
Malaysia’s road transport sector contributes significantly to national energy consumption and CO₂ emissions. This study develops a simplified comparative model to assess the operational energy use and CO₂ emissions of gasoline internal combustion engine vehicles (ICEVs), hybrid electric vehicles (HEVs), and electric vehicles (EVs) under Malaysian passenger-car conditions. Useful traction energy was estimated at 13.76%, 23.48%, and 69.19% for ICEVs, HEVs, and EVs, respectively. Compared with ICEVs, HEVs and EVs reduced annual operational CO₂ emissions by 38.69% and 45.96%, respectively, although EV performance remains strongly dependent on the electricity-generation mix. Scenario analysis indicates that electrification alone is unlikely to deliver rapid transport-sector decarbonisation without aggressive adoption, grid decarbonisation, and supporting infrastructure. HEVs and improved ICEV technologies can provide short- to medium-term transition benefits, while EVs offer stronger long-term potential with the expansion of renewable electricity, charging infrastructure, and clear policy support. The findings support a balanced transition strategy that combines electrification, vehicle efficiency improvements, and power-sector decarbonisation.
