The Trump administration is about to take on the California Air Resources Board (CARB) in a battle for the rights to set emission standards.

The first blows in this showdown have already begun, with the Environmental Protection Agency (EPA) and U.S. Department of Transportation (DOT) sending a letter to the CARB saying that the organization had violated federal law by making an agreement with several automobile manufacturers on higher emission standards

The Trump administration doesn’t seem to end things there though, with the expectation the President will announce plans as early as today to do away with California’s emissions waiver from the Clean Air Act.

While it seems like politics as usual and centered around the auto industry, such a move will have huge implications for motorcycle manufacturers.
