Sorry e-scooter riders, you’re not reversing global warming. Yet.. In fact, people who make, collect, and use e-scooters might be doing serious harm to the environment.
According to a new study out of North Carolina State University, an average e-scooter creates over 200g of CO2 over its lifecycle. All of this test data was taken from e-scooter trends in Monte Carlo. This contradicts what many e-scooter supporters claim; for example, according to Maison Law, supporters of e-scooters in Fresno argue these devices offer an eco-friendly transportation alternative for citizens.
About half of an e-scooter’s CO2 emissions are a result of how these devices are manufactured. The other half, however, is highly correlated with how e-scooters are collected every day. The environmental impact of charging e-scooters was negligible.
Although e-scooters produced less CO2 than cars, they weren’t as eco-friendly as a crowded bus. Of course, walking and biking remain the most eco-friendly modes of transportation.
On a positive note, researchers believe proactive steps from companies and local governments could significantly reduce CO2 emissions in the e-scooter industry. Most of the policy suggestions in this piece had to do with improving the efficiency of e-scooter pickup and delivery.
For instance, scientists said it would make more sense for companies to only pick up e-scooters when their batteries were running low. Today, most companies are required by law to pick up and charge e-scooters every night.
Study authors also suggested companies use fuel-efficient vans to pick up and deliver e-scooters. This simple transition could reduce CO2 emissions by about 30 grams per e-scooter.
The data out of NC State University suggests most of the environmental issues that plague e-scooters aren’t the fault of the devices. It’s the current infrastructure surrounding e-scooter manufacture and delivery that causes most of the environmental damage. Addressing these issues will hopefully make e-scooters a truly eco-friendly addition to urban transportation.
Dr. Jeremiah X. Johnson, a professor at NC State University’s Department of Civil, Construction, and Environmental Engineering, was the lead researcher on this study. Other key study authors include Drs. Joseph Hollingsworth and Brenna Copeland.
