UK researchers report that alcohols in windshield washer fluid are major unreported source of VOCs emissions from cars, including EVs

Green Car Congress

A fleet average nonfuel nonexhaust VOC emission factor of 58 ± 39 mg veh –1 km –1 was calculated for the missing source, which is greater than the total of all VOCs emitted from vehicle exhausts and their associated evaporative fuel losses. While some VOCs are released in exhaust, others may arise from an unexpected source—e.g.,

HEI launches two new non-tailpipe particulate emission studies

Green Car Congress

Emissions from automobile exhaust systems have decreased in recent years due to the introduction of cleaner fuels and new control technologies on internal combustion engines, as well as increases in numbers of hybrid and electric vehicles. Establish a bio-bank of samples to support future HEI-sponsored research in this area.

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.

HEI ACES study of lifetime animal exposure to New Technology Diesel Engine exhaust finds no lung cancer

Green Car Congress

The first study to conduct a comprehensive evaluation of lifetime exposure to new technology diesel exhaust (NTDE)—i.e., exhaust from heavy-duty diesel engines meeting EPA 2007 and later emissions requirements—has found no evidence of carcinogenic lung tumors. Earlier post.) Advanced Collaborative Emissions Study (ACES).

Study Finds Controlling Soot May Be Fastest Method to Reduce Arctic Ice Loss and Global Warming; Second-Leading Cause of Global Warming After CO2

Green Car Congress

Results of the study suggest that soot is second only to carbon dioxide in contributing to global warming. Jacobson found that the combination of the two types of soot is the second-leading cause of global warming after carbon dioxide. Particle traps filter out soot particles from exhaust fumes. Jacobson at Stanford University.

London and Paris launch car scoring initiative based on real-world emissions; ICCT the technical lead

Green Car Congress

This new undertaking will capture detailed information on pollutants from vehicle exhaust using remote-sensing equipment and portable emissions monitoring systems. The meeting, was the first such effort by city leaders and car manufacturers to work together in planning for a sustainable future.
