Abstract The environmental impacts of transportation network companies (TNCs) have been under intense debate with conflicting claims. However, there are limited empirical studies that quantify TNCs’ environmental impacts. This study examines the impact of TNCs on urban air quality in 388 metropolitan statistical areas (MSAs) in the U.S. over the period from 2010 to 2018. Based on difference-in-differences and yearly regression models, we generate three major findings: (1) The entry of TNCs has a positive impact on the overall urban air quality measured by AQI; (2) despite the positive impact on the overall air quality, TNC entry increases CO and NO2 pollution; and (3) TNC entry reduces PM10 pollution but has no statistically significant impact on PM2.5 pollution, and the effect on PM10 reduction takes 2 years to appear. The findings provide useful insights into the management and design of shared mobility and urban transport systems.
