Northwestern/Princeton study explores air quality impacts of aggressive conversion to EVs

Green Car Congress

Researchers from Northwestern University and Princeton University have explored the impact on US air quality from an aggressive conversion of internal combustion vehicles to battery-powered electric vehicles (EVs). This despite evidence that suggests air pollution impacts from the transportation sector exceed those from greenhouse gases. …

6PPD-quinone derived from tire debris is toxic to two trout species, not just coho salmon

Green Car Congress

Every time it rains, fish living downstream of storm drains are exposed to pollutants, including the tire-derived compound 6PPD-quinone, in the runoff. 6PPD is an antioxidant and antiozonant that helps prevent the degradation and cracking of rubber compounds caused by exposure to oxygen, ozone and temperature fluctuation.

Test of Planet-Cooling Scheme Could Start in 2022

Cars That Think

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Even less is understood about the potential risks to people and the environment—could the particles deplete the ozone layer, for example, or significantly alter the weather?

Study finds paved surfaces in Houston worsen air quality

Green Car Congress

New research by a team from the US, China and Japan focusing on the Houston, Texas area suggests that widespread urban development alters weather patterns in a way that can make it easier for pollutants to accumulate during warm summer weather instead of being blown out to sea. ““The very existence of the Houston area favors stagnation.”
