Carbon neutrality may take 2-100 years for biofuels feedstocks, say researchers

In Sweden, researchers at the University of Gothenburg have shown that calculating the carbon lifecycle of biofuels is much more complex than previously thought, with between two and 100 years required for a feedstock to become carbon neutral depending on a variety of factors. Therefore policy should be based upon feedstock whose carbon neutrality can be achieved in x-number of years, such as 20 years.
