In order to evaluate the true impact of the fuels we use we need to know the well to wheel carbon output of the fuel. That means we need to look at all of the carbon emissions that go into producing, distributing and using the fuel. With a well-to -heel analysis, a locally produced algae biodiesel would probably be much cleaner than electricity produced at an older, coal-fired power plant.
The state of California wants to give their residents the opportunity to purchase low-carbon fuels so they will be publishing rankings of the full life cycle carbon emissions of various fuels. Governor Arnold Schwarzenegger wants to cut vehicle fuel carbon ten percent by 2020. Schwarzenegger's plan would also allow for credits for companies selling low carbon fuels.
