Obama's a busy man

His administration is announcing new car mileage and emissions standards:

The rules, which will begin to take effect in 2012, will put in place a federal standard for fuel efficiency that is as tough as the California program, while imposing the first-ever limits on climate-altering gases from cars and trucks.

The effect will be a single new national standard that will create a car and light truck fleet in the United States that is almost 40 percent cleaner and more fuel-efficient by 2016 than it is today, with an average of 35.5 miles per gallon.

And he has support from both environmental groups and the auto industry.
