Banning SUV's would be a good start, as apart from seriously wasting fuel your average SUV driver appears to be a complete inconsiderate moron on the road!
I like SUVs, so they stay

Let say the tax raises oil to $2 a gallon. an suv gets say 10 mpg, and a lil ole compact gets say 40 mpg.
two folks both commute 40 miles a day. (radical simplification to assume all transport is commuting - you want more detailed analysis you gotta pay me

So it costs 2 bucks a day for the compact, 8 bucks a day for the SUV.
Person A only slightly values the benefits of the SUV. Its not worth it to him, and we have one less SUV on the road.
Person B hates bending over to get in a compact, carries loads of stuff to work and back, etc. So to them maybe the 8 bucks a day is worth it and they buy the SUV despite the tax.
The market solution works - less SUV's are bought, but those who really want them can still buy them.
And even neater stuff happens.
Person A and B both usually go to a movie in the neighborhood movie theater (cinema for you furriners) "Harry Potter and trip to Alpha Centauri" is playing locally, but also at the giant screen theater across town which requires a trip of, you guessed it, 40 miles. It cost person B (who owns an SUV) $8 to go to the big screen, so he settles for watching harry on the local screen. Person A, who owns the compact, only has to pay $2 more for the trip across town, so he goes to see harry build a new civ among the aliens at the huge screen far away.
So thanks to our tax, the person with the gas guzzler is incented to avoid unnecessary trips (an SUV in the garage is no threat to the environment) while the person with the gas frugal car can still make their (not so) wasteful trips.
