The article discusses how European biofuel policies impact agricultural markets and the environment. The researchers used a model to analyze the effects of biofuel production on global markets, focusing on Europe. They found that by 2020, the EU's biofuel target will increase global trade, with more biodiesel from the USA and Argentina and ethanol from Brazil coming into the EU. This will lead to the EU importing more biofuels. The increased demand for biofuels will affect agricultural markets, with some of the demand being met by imports and substitutions in the feed market.
