ICCT | Highlighted on Fuelcons
The actual impact of plug-in hybrid and battery electric vehicles (PHEV and BEV) on greenhouse gas (GHG) mitigation depends on their real-world usage. PHEVs, with their smaller batteries compared to BEVs, which implies lower emissions during vehicle production, can contribute to GHG emission reduction. However, their overall environmental impact hinges on efficient operation and the Utility Factor (UF), quantifying the electric distance fraction. Accordingly, fuel consumption and CO2 emissions of PHEVs are correlated with operating environments (e.g. private vs. company cars) and charging frequency. Two white papers from the International Council on Clean Transportation (ICCT) recently delved into PHEV real-world usage in Europe and the US, addressing the divergence between real-world and type-approval (WLTP/EPA) fuel consumption.
