HEI launches two new non-tailpipe particulate emission studies

Green Car Congress

JANUARY 8, 2023

The Health Effects Institute (HEI) has launched two new studies funded under RFA 21-1, Quantifying Real-World Impacts of Non-Tailpipe Particulate Matter Emissions. The new studies are: Improved Characterization of the Real-World Contributions and Impacts of Non-tailpipe Particulate Matter Emissions ,” led by Greg Evans, University of Toronto.

A new study from UC Berkeley confirms what EV fans already know: EV adoption does, in fact, make the air cleaner. Perhaps even more importantly, the study offers some quantifiable, granular data about how much electric vehicles are impacting emission rates in the here and now, not in the foreseeable future. annually. “We
