Towards Sustainable Public Transportation: Evaluating the Carbon Reduction Potential of E-Jeepneys in the Philippines

抄録

Electric jeepneys (e-jeepneys) offer a cleaner alternative to traditional jeepneys that remain essential to the Philippine public transport system. This study examines the environmental impact of integrating e-jeepneys using a bottom-up approach with consideration to fleet composition, trip data, and fuel consumption. Four scenarios were analyzed: Business-As-Usual (BAU), Abrupt Jeepney Phaseout, Slow Jeepney Phaseout, and a Clean Energy Scenario. Findings show e-jeepneys lower operational emissions by 1.31 MTCO2 but increase power demand by 3.39 TWh, raising power generation emissions if the electricity mix remains unchanged. This shows that while e-jeepneys reduce vehicle emissions, their carbon reduction potential is limited by the current energy mix. Transitioning to renewable energy then plays a crucial role since a 48.2% emission reduction with the Clean Energy scenario was observed. The study emphasizes the need for investments in renewable infrastructure to maximize e-jeepneys' environmental benefits, ensuring meaningful carbon reductions alongside electrification.
