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. The results are less clear in Dallas and Houston.

NASA satellite images highlight US air quality improvement with reduction of NO2

Green Car Congress

After ten years in orbit, the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite has been in orbit sufficiently long to show that people in major US cities are breathing less nitrogen dioxide. New NASA satellite images released this week demonstrate the reduction of air pollution across the US.

Research shows clean fuel-use for ships off California coast extremely effective in reducing sulfur dioxide pollution

Green Car Congress

The California data were compared to ship-plume measurements made by NOAA near the Port of Houston, Texas in 2006. One finding was that container ships encountered off the Port of Houston, where no clean-fuel use is required, emitted four times as much sulfur dioxide.

Study finds marine workboat engines staying in service two times longer than estimated by EPA; emissions reduction implications

Green Car Congress

This finding reveals important opportunities for clean air improvements, especially in large port cities such as New York and Houston. The incentive funds give boat operators a brand new, more efficient, fuel-saving and lower-emitting engine at a fraction the cost.
