Study finds all-electric rideshare fleet could reduce carbon emissions, but increase traffic issues

Green Car Congress

They used the model and the data to estimate the life cycle air pollution, greenhouse gas, and traffic externality benefits and costs of serving rides based on Chicago TNC trip data from 2019 to 2022 with fully electric vehicles. The authors acknowledge funding from Carnegie Mellon University’s Wilton E.

New study finds gasoline stations vent up to 10x more benzene fumes than previously thought

Green Car Congress

The findings appear in the journal Science of the Total Environment. At gas stations, fuel vapors are released into the atmosphere from storage tanks through vent pipes. Our goals were to quantify vent pipe releases and examine exceedance of short-term exposure limits to benzene around gas stations. —Hilpert et al.
