Biodiesel's troubles in Texas

Wired News' Autopia blog is reporting on trouble brewing in Texas over biodiesel. It turns out that Texas has high standards over nitrogen oxide (NOx) emissions. Trouble is, some studies say that biodiesel increases NOx emissions by 2% in B20 (EPA, 2002), while other studies say that NOx emissions are the same or increased by 0.5% (National Renewable Energy Lab, 2003).

Biodiesel's fate will be decided by the Texas Commission on Environmental Quality, which has decided to spend the next year to study the effects of Biodiesel on vehicle exhaust. Lucky for me, I will be passing through while Biodiesel is still legal in the state of Texas.
