Dubious design and inefficient operations are just some of the reasons why shared scooters’ eco-credentials are thin.
Early fleets lasted just a few months, even in the best cases. And with their aluminum frames and lithium-ion batteries, replacing them meant emitting a. “Amortizing lithium-ion batteries plus the manufacturing emissions over 200 trips rather than 2,000 trips doesn’t look good,” Matute says.
Combine these manufacturing and operational emissions and you account for the bulk of a rental program’s environmental impact. The researchers of the North Carolina study calculated that 93 percent of a shared e-scooter’s carbon footprint falls into these categories. Companies are also making their scooters longer lasting. Between 60 and 70 percent of e-scooter operators—including European giants like Tier and Bolt—source their scooters from either Segway-Ninebot or Okai, and both companies have worked to design more robust and durable products. Even Okai’s basic model, the choice of e-scooter for cash-strapped operators, is expected to last around two years.
But as it stands, the ecocredentials of most e-scooter rental programs are foggy. Despite recent improvements that operators have flagged, they’re still cagey about disclosing how scooters are manufactured, what their current life cycles are, and how they’re collected, charged, and distributed.

Big Oil profits aren’t driving gas prices, experts say, despite Biden’s ‘price gouging’ accusationsBig Oil has been the go-to boogeyman for President Biden and Democrats over alleged “price gouging,” with “Putin’s price hike” a close runner-up. But profits made by the oil industry — while at record levels — ebb and flow with global energy markets, not because the firms are manipulating costs, according to market analysts.
