The Top Five Biofuel Crops

Rapeseed / Canola (2/5)

Major cultivation regions: European Union, China, Canada, India

Worldwide production in 2006: 46 million tons

Sustainability:
+ not a food crop: does not disturb markets
- needs fertilizers, water, good soils, and subsidies
- energy balance: producing rapeseed biodiesel might produce more CO2 than consuming biodiesel prevents
