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.

KIT study finds extraordinarily cold Arctic stratospheric winter enhanced ozone degradation above the Arctic

Green Car Congress

Extraordinarily cold temperatures in the stratosphere during the winter of 2010/2011 caused the most massive destruction of the ozone layer above the Arctic so far, according to a study by climate researchers at KIT (Karlsruhe Institute of Technology). These chemical conversion products attack the ozone layer and destroy it partly.

National Research Council report finds it unlikely the US will meet cellulosic biofuel mandates absent major innovation or a change in policies

Green Car Congress

One opportunity to reduce the cost of biofuels is to reduce the cost of bioenergy feedstock, which constitutes a large portion of operating costs, and increase the conversion efficiency from biomass to fuels. Currently, no commercially viable biorefineries exist for converting cellulosic biomass to fuel. Barriers and opportunities.

SCOPE Biofuels Project Releases Assessment on Environmental Effects of Biofuel Technologies

Green Car Congress

Low-input cultivation of perennial plants, e.g. from short-rotation forestry and grasslands, may be an effective source of cellulosic biomass and provide environmental benefits (reduced pollution and lower greenhouse gas emissions). However very few studies include water use impacts. Ravindranath et al.

National Academies Report Examines Hidden Cost of Energy Production and Use in US; Estimates $120B in 2005

Green Car Congress

A new report from the National Research Council examines and, when possible, estimates, “hidden” costs of energy production and use—such as the damage air pollution imposes on human health—that are not reflected in market prices of coal, oil, other energy sources, or the electricity and gasoline produced from them.
