MIT study: half of US deaths related to air pollution are linked to out-of-state emissions

Green Car Congress

More than half of all air-quality-related early deaths in the United States are a result of emissions originating outside of the state in which those deaths occur, MIT researchers report in a paper in the journal Nature. Now it’s looking like other emissions sectors are becoming important. That wasn’t really possible before.

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.

Study finds US air pollution deaths nearly halved between 1990 and 2010

Green Car Congress

Improvements in air quality and public health in the US coincided with increased federal air quality regulations, and have taken place despite increases in population, energy and electricity use, and vehicle miles traveled between 1990 and 2010. and ozone from a 21-year computer simulation of air pollution across the US.

Calif. ARB releases GHG scoping plan update; more ZEVs, “LEV IV”, MD and HD regulations; ZEV for trucks; more LCFS

Green Car Congress

The California Air Resources Board released the draft proposed first update to the AB 32 Scoping Plan, which guides development and implementation of California’s greenhouse gas emission reduction programs. California’s zero emission vehicle (ZEV) regulation is also driving a transformation of the fleet. Transportation.

The New Supersonic Boom

Cars That Think

Meanwhile, environmentalists were voicing concern—about how noisy such aircraft are taking off, about the possibility that their high-altitude emissions would erode the ozone layer, and about how disruptive the sonic booms would be. 1,100 miles per hour) without producing a loud, disturbing sonic boom on the ground."
