Greater fuel economy = lower C02 emissions, regardless of what fuel you burn. Biodiesel isn't a silver bullet, but in the real world nothing ever is. Bio and the development of alternative fuels contributes (in a small way) to the shift away from dino oil is all there is and all there will ever be. And it means that at least my money isn't going to anti-American oil barrons and theocracies.
And a good number of folks have used their CRD's for home-brew biodiesel from waste oil, or for straight WVO projects.
Anyway, back on topic, it will be interesting to see whether the automakers actually roll out some of this technology. The hybrid tech was actually developed in the 1990's with public tax $$ here in the US, under something called "the Partnership for a New Generation of Vehicles." Toyota thought it was a big threat to their long-term bottom line, so they started developing their own. The US Big 3, the beneficiaries of that tax money, put their results up on a shelf (including an 80 mpg diesel electric hybrid prototype) and ignored them. Had they taken the long view, you might be able to buy your 40 mpg Jeep today.
