Until a few years ago biofuels were considered a robust option for reducing CO2 emissions. However, over the past few years much evidence has emerged that this thinking is only part of the story and that it does not capture the full climate impact of biofuels.
The European Union established a 20% target for renewable energy use by 2020 and a 10% target for renewables in the transport sector by 2020. Bioenergy, including solid biomass and waste, is expected to represent 60% of the EU’s renewable energy use and biofuels is expected to cover most of the 10% renewable energy use in transport.
The average performance of light commercial vehicles has increased during the last
decades. Due to this enhanced performance, the achieved levels of fuel consumption
and CO2 emission reductions are smaller than the engine efficiency improvements
realized in the same period. A possible way to realize this full potential is by
