  • A new study has found that ride-sharing services result in much more pollution than other kinds of private and public transportation.
  • 2
  • Ride-sharing trips also draw passengers away from more environment friendly methods of travel, like public transportation, walking or biking, the study found.
  • 3
  • Several studies in recent years have suggested that ride-sharing services like Uber and Lyft can worsen traffic problems in cities, which continue to have high rates of private vehicle ownership.
  • 4
  • The new study, carried out by the not-for-profit group Union of Concerned Scientists, represents an attempt to center on how ride-sharing services affect pollution.
  • 5
  • The research examined the effects of ride-sharing services on seven of America's largest cities.
  • 6
  • Overall, the researchers reported that ride-sharing trips now "result in an estimated 69 percent more climate pollution on average than the trips they displace."
  • 7
  • The study notes that the same passengers could have chosen to travel by bus, train, bike, scooter or on foot.
  • 8
  • One of the big reasons they give for this result is that ride-sharing vehicles are often driven with no passengers in the car.
  • 9
  • This happens when drivers are either waiting for rider requests, are on the way to pick up passengers or are driving in between pickups.
  • 10
  • This situation, known as "deadheading," takes up about 42 percent of all ride-sharing driving activity, the study found.
  • 11
  • The researchers said that deadheading results in about 50 percent more carbon dioxide than one person driving in a private vehicle.
  • 12
  • Both Uber and Lyft do offer a choice of a "pooled" ride, which involves drivers picking up additional riders during the same trip.
  • 13
  • The study urges services like Uber and Lyft to work to increase the amount of pooled rides.
  • 14
  • It also urges the two companies to increase the number of electric vehicles on the road and to improve connections to public transportation centers.
  • 15
  • Both Uber and Lyft have said in the past that most studies on the subject overstate the effects of their services on pollution.
  • 16
  • They have noted that the majority of vehicles on the road belong to private individuals or companies.
  • 17
  • Uber told Reuters news agency in a statement it had no comment on the latest report.
  • 18
  • But the company said it aims to be part of the solution to address climate change by working directly with cities.
  • 19
  • The statement added that Uber would continue to promote pooled trips and other means of transportation.
  • 20
  • Lyft told Reuters in a statement that the study made misleading claims about ride-sharing.
  • 21
  • But the company said it shares the goals of increasing the number of pooled rides and putting more electric vehicles in service.
  • 22
  • Both companies already operate businesses that offer electric scooters and bikes and have begun to include public transportation information in their systems.
  • 23
  • In some cities, they have also promoted vehicle electrification.
