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.

California Air Resources Board posts revised draft of strategy to reduce “Super Pollutants”

Green Car Congress

NOVEMBER 29, 2016

The California Air Resources Board (CARB) has posted a revised draft of California’s proposed Short-Lived Climate Pollutant (SLCP) Strategy. SLCPs are a category of pollutants which remain in the atmosphere for a relatively brief period, but have global warming potentials that are much higher than those of CO 2. Black carbon.

EPRI-NRDC report finds widespread vehicle electrification and a cleaner grid could lead to substantial cuts in GHG by 2050

Green Car Congress

SEPTEMBER 21, 2015

Use of electric vehicles would achieve greater reductions in GHG emissions, corresponding to the rate that the electric grid becomes cleaner, through greater reliance on renewables and low- and non-emitting generation. With a 62% share of light- and medium-duty vehicles in 2050 electric vehicles would consume 13% of grid-supplied electricity.

Urban regions account for an ever increasing fraction of Earth’s population, and are consequently an ever increasing source of air pollutants. These pollutants include anthropogenic aerosols, which have important climate and health implications.

The California Air Resources Board (ARB) and the National Oceanic and Atmospheric Administration (NOAA) are collaborating in the $20-million CalNex research project to examine the nexus between air pollution and climate change. The complex roles that ozone and aerosols play in the atmosphere provide examples of such trade-offs.

Researchers describe the “where” and “when” of life cycle emissions from gasoline and ethanol in the US

Green Car Congress

OCTOBER 11, 2012

Researchers from the University of Minnesota have produced a spatially and temporally explicit life cycle inventory (LCI) of air pollutants from gasoline, ethanol derived from corn grain, and ethanol from corn stover for the contiguous US (the lower 48 states). The researchers included a sixth pollutant, ammonia (NH 3 ).
