“RMI analysis indicates that the United States must reduce VMT by 20 percent before the end of the decade to limit warming to 1.5°C—and this remains true even under ambitious EV adoption scenarios.”
The source article is discussing, without sharing their supporting evidence, the transition to EVs. If 100% of vehicle miles were driven by EVs charged with clean energy there would be no need to reduce mileage. We're talking about city design for the next hundred years. Not the transition to EVs over the next 5 to 20 years.
Clean energy and clean transportation is possible. Some might even say it's inevitable. Once achieved there is no existential requirement to reduce vehicle miles.
Nonsense. It's perfectly possible for us to achieve clean energy and clean transport.
