Road trips make nearly 70 percent more pollution than the modes of transport they replace by adding more cars to the road and generating more traffic, the study says.
- The analysis uses publicly available data to assess the impact of driving a lift
- It is found that rides hate cause 69 percent more pollution than journeys that they move
- Non-pooled journeys usually correspond to a longer driving time
- The use of ride hailing also increases the total number of car trips
- Scientists recommend encouraging pooled journeys and using electric vehicles
Riding companies are much worse for the environment than the modes of transport that they replace according to a new analysis.
Published in a study this week by the Union of scientists involved evaluating publicly available data on journeys from seven major US metro lines, researchers say that journeys from Uber and Lyft companies cause on average about 69 percent more pollution than the journeys they move.
Behind the inequality, scientists say, are longer driving times, increased congestion and an increase in the total number of car journeys in addition to reducing the number of journeys on public transport.
The Union of Concerned Scientists (USC) estimates that a non-pooled ride with journeys generates approximately 47 percent more emissions than a private car journey in a vehicle with average fuel efficiency due to factors such as ‘deadheading’ or the amount of time a driver travels without a passenger to be around to reach the next collection point.

In addition, the USC says that instead of reducing or replacing the number of car journeys, companies that drive are increasing the volume with many riders who choose to use Uber or Lyft instead of more environmentally friendly modes of transport such as buses or trains.
Uber already registered 10 billion journeys worldwide in 2018, while Lyft had facilitated 1 billion.
The abundance of journeys that make travel possible also contributes to congestion in urban areas, scientists say another factor behind increased emissions.
prior studies have linked the impact of congestion to greater fuel consumption and subsequently increased emissions.
In urban areas such as San Francisco and Manhattan, the latter of which saw double the number of journeys and taxi rides between 2010 and 2017, congestion has slowed the average travel time by a few kilometers per hour.
Despite the negative impact, researchers say that companies that come by car can take various plausible measures to reduce their CO2 footprint.
Among them, according to the USC, traditional combustion engine vehicles are being replaced by electric cars.
Their analysis shows that an electric, combined ride can reduce emissions by 68 percent compared to a ride with a private vehicle in an average car. In comparison with a non-pooled ride in a personal car, that percentage increases by 79 percent.

In addition, the USC says that companies coming with the ride can encourage more pooled rides by offering ‘attractive prices’, although both major services are already offering discounted rides through the pooling option, suggesting that convenience and privacy are probably the deciding factor. give for most riders.
Whether Uber or Lyft has the will to pursue more environmentally friendly policies is also an open question.
Lyft outlined a plan to become “CO2 neutral” in 2018, but those plans, which purchase CO2 offsets, have questionable effectiveness and are not enforced outside of the company’s own promise.
Uber has done even less to reduce its emissions, except for the idea of providing drivers with incentives to use electric or hybrid vehicles.
