Washington plans to adopt California’s tough new auto emissions rules with its existing fuel economy limits as new national standard.

The Obama administration plans to combine California’s tough new auto-emissions rules with existing fuel economy limits to create a single new national standard.

President Barack Obama, seeking to end a stand-off between states and the auto industry, plans to issue new national emission limits and mileage requirements for cars and trucks.

Obama plans to announce on Tuesday that he will couple pollution reduction from vehicle tailpipes with increased efficiency on the road.

It would be the first time that limits on greenhouse gases were linked with federal standards for passenger cars and light trucks.
