UB study finds link between ambient ozone exposure, artery wall thickness

Green Car Congress

Long-term exposure to ambient ozone appears to accelerate arterial conditions that progress into cardiovascular disease and stroke, according to a new University at Buffalo study. The study found that chronic exposure to ozone was associated with a progression of thickening of the main artery that supplies blood to the head and neck.

Study finds anthropogenic PM and dust undercutting global solar energy production

Green Car Congress

With colleagues at the Indian Institute of Technology-Gandhinagar (IITGN) and the University of Wisconsin at Madison, Michael Bergin, professor of civil and environmental engineering at Duke University and lead author of the study, measured the decrease in solar energy gathered by the IITGN’s solar panels as they became dirtier over time.

MIT study finds air quality co-benefits of US carbon policies can significantly offset costs, depending upon the policy

Green Car Congress

Selin and colleagues compared the health benefits to the economic costs of three climate policies: a clean-energy standard, a transportation policy, and a cap-and-trade program. In 2011, 231 counties in the US exceeded the EPA’s regulatory standards for ozone, the main component of smog.

Lifecycle study finds that environmental impacts of silicon-anode Li-ion battery could be roughly comparable with conventional Li-ion battery

Green Car Congress

The results demonstrate that the major opportunity for reducing the life cycle impacts of the battery pack is to use clean energy supply for battery operation, such as solar and wind electricity, which could reduce these environmental impacts significantly.
