The directive sets mandatory targets for EU member states to ensure a share of 20% renewable energy in total energy consumption. For the transport sector a mandatory share of 10% renewable energy is required in 2020, which is expected to be met mainly with biofuels. The criteria include minimum GHG savings for biofuels of at least 35% compared to fossil fuels from 2013 onwards, rising to 50% in 2017 and 60% in 2018. Furthermore, the directive determines that biofuel feedstock must not be grown on environmentally sensitive land, including protected areas and land with high biodiversity value or high carbon stock.
