Fig. 4: Change in PM2.5 exposure inequalities by racial–ethnic group from truck electrification grid emissions.
From: Impact of truck electrification on air pollution disparities in the United States
a, Absolute exposure disparity by year from electric trucks for each racial–ethnic group compared to the total population. b, Relative exposure disparity by year, including diesel and electric trucks, compared to the total population. Results represent a low renewable energy cost scenario.
