"MEPs say "first-generation" biofuels - from crops like corn - should not exceed 6% of fuel used in transport by 2020, amending the target from 10%. They want "advanced biofuels" - sourced from seaweed or certain types of waste - to make up at least 2.5%. Biofuels have been seen as a way to cut fossil fuel use, but using food crops can displace food production." (Quoted from article)
