General Observations Regarding LCA of <strong>Biofuels</strong><br />
• Importance of indirect effects is now recognized<br />
– No consensus on how to quantify these effects<br />
– No consensus on how (or if) to incorporate into policy<br />
• LCA results are highly scenario specific – very difficult to<br />
generalize for a particular biofuel<br />
• 2 nd generation biofuels are clearly preferred over 1 st<br />
generation biofuels<br />
