The Environmental Protection Agency announced tough new emissions limits in April, which the agency says are vital to slowing climate change as people around the world endure record-breaking temperatures, raging fires and intense storms. The EPA says the industry could meet the limits if 67% of new vehicle sales were electric by 2032, a pace the auto industry calls unrealistic. But the new rule won’t require automakers to directly increase sales of electric vehicles. Instead, it sets emissions limits and lets automakers choose how to meet them. (Tom Krisher)
