This spring, however, the Trump administration rolled back Obama-era regulations that would have required vehicles to have an average fuel economy of 54. 5 miles per gallon by 2025.
Per the California rules, they’ll need to improve their vehicles’ fuel economy from the current average of around 38 miles per gallon to approximately 51 miles per gallon by 2026.
Five major automakers have signed a binding agreement with California that will compel them to follow the state’s vehicle emissions standards.
The deal they signed with the state this week will mean they have to abide by those guidelines. “We went into this voluntarily, but it is now binding, it’s enforceable,” Spencer Reeder, director of government affairs and sustainability at VW-owned Audi of America, told the New York Times.
Thirteen other states, including New York and Washington, follow California’s standards and will enforce the binding agreement.
In doing so, the companies have effectively made a nationwide commitment to selling vehicles that are more fuel efficient and have lower emissions than are required by federal regulations.
Its fuel economy rules are stricter than federal ones, which has put the state at odds with the Trump administration.
But regardless of whether Biden or Donald Trump win the White House, those five automakers will abide by California’s standards.
Ford, Honda, BMW and Volkswagen agreed in principle to follow California’s standards in July 2019, as did Volvo in March.
They've committed to building cars that outperform federal fuel efficiency standards.
