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

Green Car Congress

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.

Study Highlights the Importance of Considering Climate Effects of Non-CO2 Emissions from Transport in Mitigation Strategies and Policies

Green Car Congress

The on-road transportation (ORT) and power generation (PG) sectors are major contributors to CO 2 emissions and a host of short-lived radiatively-active air pollutants, including tropospheric ozone and fine aerosol particles, that exert complex influences on global climate.
