Yesterday, the Supreme Court ruled that the EPA could regulate CO2 and other greenhouse gases coming from new cars and trucks.
Erm. This could put a crimp in our automotive lifestyle. I don't know about the other gases, but CO2 is practically impossible to scrub out of exhaust meaning that this is pretty much another avenue to impose mileage requirements on cars.
This is really quite amazing, because Carbon Dioxide is not actually a pollutant, as such. We breath vast amounts of it in and out every day. In fact, it is the fourth most common gas composing our atmosphere after Nitrogen, Oxygen and Argon. It is not poisonous.
Interesting is that the court begins it's opinion citing current thinking on global warming, a matter of still substantial debate. Man made CO2 caused global warming is absolutely not settled science. One wonders, if the opinions shift and, for instance, solar flux turns out to be the real cause of temperature variation does that automatically invalidate the courts ruling? Of course not.

Oh sure, this will reduce gas milage... but we have this to compensate:

You link might be broken due to formatting. Here it is as again: Auto Prize.
It will be interesting to see what the specs for a winning entry are. better than 100MPG is already claimable by some examples like any electric only car (the Corbin Sparrow, for instance).
