Advantages of second-generation biofuels Harm-01 A public consultation carried out by the Commission between April and July 2006, http://www.euractiv.com/ " They have a more favourable GHG balance . Cellulose ethanol could produce 75% less CO2 than normal petrol, whereas corn or sugar-beet ethanol reduces CO2 levels by just 60%. As for diesel, Biomass-to-Liquid (BtL) technology could slash CO2 emissions by 90%, compared with 75% for currently-available biodiesel; They are able to use a wider range of biomass feedstocks, and do not compete with food pro- duction ; They could use less land . For example, a new genetically modified variety of sugarcane is able to produce up to 200 tonnes of biofuels per hectare. In this case, plant science could triple pro- duction volumes per hectare of land. They could be produced at cost-competitive prices, especially if low-cost biomass is used, and; They offer a better quality of fuel than first-generation biofuels.” * Independent specialised European Union affairs portal for EU policy professionals. Challenges of second-generation biofuels Harm-02 A public consultation carried out by the Commission between April and July 2006, http://www.euractiv.com/ Cost: Relatively high production costs (currently higher than those for both mineral oil-based petrol and conventional bio-ethanol) mean that second-generation biofuels cannot yet be pro- duced economically on a large scale. Technological breakthroughs: Key developments are needed on enzymes, pre-treatment and fermentation in order to make processes more cost- and energy-efficient. Biotechnology could offer a solution by offering the opportunity to change the characteristics of feed materials for
