Comparing the Environmental Impact of Conventional and Electric Jeepneys, Accounting for Idling Emissions: A Case Study Using Actual Transportation Data from UP Diliman Campus

Abstract

This study analyzes the Energy Demand and Emissions of Traditional PUJs in UP Diliman Campus using real transportation data from 2018, considering idling emissions. The objective is to assess the energy demand and emissions reduction potential when transitioning to electric PUJs. The findings reveal that the total transportation activity of all PUJs in UP amounted to 5,696,777.65 vehicle-kilometers, with an energy demand of 0.878 ktoe, including idling energy demand. However, if all PUJ units switch to electric PUJs, the energy demand significantly decreases to 0.145 ktoe, demonstrating the greater energy efficiency of electric jeepneys. Regarding PUJ emissions, three key insights were identified: idling emissions are a significant source of emissions for PUJs in UP Diliman, GHG emissions reduction attributed to shifting to electric PUJs depends on the power generation mix, and adopting electric PUJs significantly lowers PM and NOx emissions, known to cause respiratory illnesses and premature mortality.
