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

Green Car Congress

Regulatory regimes seeking to reduce emissions from transport have largely focused on tailpipe emissions—i.e., the criteria pollutants and CO 2 that emerge with the exhaust from the tailpipe. Non-exhaust PM factors include tire wear, brake wear, road surface wear and resuspension of road dust. earlier post ). Background.

CMU study finds SOA levels in cities like LA will remain high despite cleaner cars; nonlinear relationship between SOA and NOx

Green Car Congress

The findings of a study by researchers at Carnegie Mellon University, with colleagues at UC Berkeley, suggest that changing atmospheric NO x levels over the next two decades will likely significantly reduce the effectiveness of stricter new gasoline vehicle emissions standards in reducing concentrations of secondary organic aerosol (SOA).
