Consequences for biofuels application

A hundred percent reduction of greenhouse gas emissions will not be possible if biofuels of the first generation are applied. Better results would occur if, besides biofuel production, also power production during a combined process is envisaged. Thus instead of the simple replacement of fuels combined technological developments are to be supported.

If a replacement is envisioned in a first approach, it will be best to focus on such feed-stocks which result in a more than 50 percent emission reduction throughout the total supply chain. In future 80 percent reduction should be envisaged as the target. Moreover, the production of biofuels should also fulfill criteria concerning the origin, the production chain, and social aspects, especially when imported from less developed countries (EEB, 2005), as well as a full LCA.

Only with 2nd generation biofuels is a mostly greenhouse gas free fuel-supply possible which also does not need fossil fuel inputs (Picard, 2006).
