The change to planned rules was an election-year concession to labor unions and auto executives, according to people familiar with the plan.

In a concession to automakers and labor unions, the Biden administration intends to relax elements of one of its most ambitious strategies to combat climate change, limits on tailpipe emissions that are designed to get Americans to switch from gas-powered cars to electric vehicles, according to three people familiar with the plan.

Instead of essentially requiring automakers to rapidly ramp up sales of electric vehicles over the next few years, the administration would give car manufacturers more time, with a sharp increase in sales not required until after 2030, these people said. They asked to remain anonymous because the regulation has not been finalized. The administration plans to publish the final rule by early spring.
