The importance of considering non-exhaust traffic emissions; the role of EVs

Green Car Congress

the criteria pollutants and CO 2 that emerge with the exhaust from the tailpipe. However, there is more than 15 years of research showing that the contribution of non-exhaust primary particles to the total traffic generated primary particles is significant in urban areas. Further, a 2013 review by Denier van der Gon et al. Background.

Study finds total PM10 emissions from EVs equal to those of modern ICEVs; role of weight and non-exhaust PM

Green Car Congress

A new study by a team from the University of Edinburgh and independent engineering company INNAS BV has found that, when factoring in the additional weight and non-exhaust PM factors, total PM 10 emissions from electric vehicles (EVs) are equal to those of modern internal combustion engine vehicles (ICEVs). Timmers and Achten (2016).

Study finds reduction of low-frequency noise from transition to electric buses improved residents’ health

Green Car Congress

Accompanying the lower noise levels from bus traffic was a reduction of fatigue, day time sleepiness and low mood, a study at the University of Gothenburg shows. The proportion who felt exhausted once or twice a week declined from 49 to 39 percent—that is, down to the same proportion as in the reference group. Applied Sciences.

CARB releases results of multi-year E15 study; multiple air quality benefits with slight reduction in fuel economy

Green Car Congress

The California Air Resources Board (CARB) has released the results of a multiyear study evaluating exhaust emissions from the use of California Reformulated Gasoline (CaRFG) that contains 15 volume percent ethanol (E15). California currently limits the ethanol content of gasoline to 10 percent. The study used two fuels—an E10 and E15.
