Texas study finds PHEV use could increase ozone at night, decrease ozone during the day

Green Car Congress

APRIL 22, 2011

A study by researchers at the University of Texas found that in general, use of plug-in hybrid electric vehicles (PHEVs) can lead to an increase in ozone during nighttime hours (due to decreased scavenging from both vehicles and EGU stacks) and a decrease in ozone during daytime hours. The results are less clear in Dallas and Houston.
