According to the Union of Concerned Scientists, ride-hailing trips today result in an estimated 69% more climate pollution on average than the trips they displace. In cities, ride-hailing trips typically displace low-carbon trips, such as public transportation, biking, or walking. Uber and Lyft could reduce these emissions with a more concerted effort to electrify its fleet of vehicles or by incentivizing customers to take pooled rides, the group recommends.
The report suggests the surge in taxi apps like Uber is actually contributing to air pollution and climate change. Data compiled by Euromonitor shows a correlation between the surge in the number of ride-share drivers in major European cities and increasing levels of air pollution.
