> The whole bio-fuel industry is a very complex mix of economics (often requires subsidies to make sense), geopolitical (less imported oil), environmental concerns (mass scale farming soil degradation and CO2 emissions derived from it) and logistical (completely different transportation and refining process).

Don't forget lobyying by the relevant sectors!

And the social implications of converting farmland from growing food to growing sugar cane/corn/soy. It is a VERY complex topic, but it seems overall it is a marginally positive thing for Brazil (even in emissions). While a very negative thing in the US because of all the subsidies required to make corn ethanol viable and overall negative emissions impact compared to oil gasoline.
