The study found that shared electric scooters are not always as environmentally friendly as other vehicles.
According to foreign media reports, a new study published by the University of North Carolina in the Environmental Research Letter found that sharing electric scooters may be more environmentally friendly than most cars, but their environmental protection may be lower than other options. .
The researchers analyzed emissions associated with four aspects of each scooter's life cycle (production of materials and components for each scooter; manufacturing process; transporting scooters from the manufacturer to their city of use; collecting, charging, and re-routing The scooter is assigned to evaluate the environmental protection of the electric scooter.
At the same time, the researchers conducted a small survey of the riders of electric scooters to see what transportation methods they would use if they did not use electric scooters. The researchers found that 49% of passengers would ride or walk; 34% would drive; 11% would take the bus; 7% would choose not to go out. These results are similar to a larger survey in Portland, Oregon.
Jeremiah Johnson, an associate professor of civil engineering and environmental engineering at the University of North Carolina, said: "The study found that cycling or electric bicycles are basically more environmentally friendly than using shared electric scooters. But the only possible exceptions are those who use paid shared bicycles because these shared bicycle companies use cars and trucks to redistribute bicycles in their service areas, which sometimes makes them less environmentally friendly than using electric scooters."
Similarly, the study found that driving a car is almost always less environmentally friendly than using an electric scooter. But some results are surprising. For example, taking a bus on a high-passenger route is generally more environmentally friendly than an electric scooter.
At the same time, Johnson pointed out: "We found that the environmental impact of electric scooter charging is quite small, accounting for about 5% of its overall impact. The real impact comes mainly from two aspects: transport vehicles used to collect and redistribute scooters; production Enter the emissions associated with each scooter's materials and components."
This means that the environmental footprint of each scooter has two main factors. First, the fewer the number of driving times to collect and redistribute the scooter, the less the impact. The second factor is the life of the scooter: the longer the scooter is used, the longer it will offset the effects of all components.
Johnson said: "There are many factors to consider, but electric scooters are environmentally friendly compared to certain modes of transportation." Companies and local governments can do something to further reduce their impact. For example, allowing or encouraging companies to collect scooters only when the battery exhaustion threshold is reached will reduce the impact of the scooter because you will not collect scooters that do not require recharging. ”
