Air quality study co-authored by Emily Fischer published in PNAS

A paper published Monday by Proceedings of the National Academy of Sciences shows that air quality improvements have slowed. It attributes this stalled emissions decline to industrial, construction, residential and diesel sources, which have increased relative to decreasing car and power plant emissions. The study “Unexpected slowdown of US pollutant emission reduction in the past decade” was co-authored by Assistant Professor Emily Fischer.
