I'm so glad that others are saying it - I've felt like a voice in the wilderness saying the medium term solution to the problem is to encourage the use of diesel. That will reduce fuel consumption dramatically.

I drive a diesel, so yes, I agree. We are wasting a lot of fuel unnecessarily, due to public perception of diesels in the U.S. (and due to unfair emissions regulations, which are modeled around gasoline emissions).
The EURO5 thing looks like it will put the kibosh on small diesels, though. That will unquestionably result in higher CO2 emissions.
BTW, in my neck of the woods, one can get soy-based biodiesel locally. When petroleum-based diesel fuel was running close to the same price, I was using it (B99). Made my old oil burner run a little smoother, but the fuel economy went down a little. Now, though, petrodiesel is quite a bit cheaper ($2.55/gal vs. $3.20/gal).
Do you have biodiesel available over there?
