Yale study finds asphalt a significant source of air pollution, especially on hot, sunny days

Green Car Congress

A new study now finds that asphalt is a significant source of air pollutants in urban areas, especially on hot and sunny days. Yale researchers found that common road and roofing asphalts produced complex mixtures of organic compounds, including hazardous pollutants, in a range of typical temperature and solar conditions.

Study Finds Asian Monsoon Carries Pollution Into the Stratosphere

Green Car Congress

The Asian monsoon circulation provides an effective pathway for pollution from Asia, India, and Indonesia to enter the global stratosphere, according to a new international study led by scientists at the National Center for Atmospheric Research (NCAR) in Boulder, Colo. NCAR scientist William Randel, the lead author.

Study finds anthropogenic PM and dust undercutting global solar energy production

Green Car Congress

According to a new study led by a team at Duke University, airborne particulate matter and dust are cutting solar photovoltaic energy output by more than 25% in certain parts of the world, with roughly equal contributions from ambient PM and PM deposited on photovoltaic surfaces.

California ARB soliciting research suggestions for FY 2012-2013 plan; sustainable communities, behavior, pollutant exposure, air pollution science, GHG targets

Green Car Congress

The FY 2011-2012 plan focused primarily on five areas of interest: sustainable communities; behavior and technology adoption; health and air pollution exposures; air pollution science; and greenhouse gas targets. These regulations have led to considerable improvements in air quality throughout California.

Study finds modifying urban form may be a strategy to reduce air pollution

Green Car Congress

Based on their findings in a new study, researchers from the University of Washington and the University of Minnesota suggest that modifying urban form—as a means of affecting motor vehicle usage—may be a strategy to mitigate urban air pollution. Their paper appears in the ACS journal Environmental Science & Technology.

Cutting Non-CO2 Pollutants Can Delay Abrupt Climate Change; The Fast Action Climate Agenda

Green Car Congress

HFCs are powerful greenhouse gases originally developed as substitutes for ozone-depleting chemicals. A binding legal agreement exists that can cut HFCs now—the Montreal Protocol ozone treaty—and many alternatives to HFCs have already been developed and are waiting for the right regulatory incentive from the Montreal Protocol to be deployed.
