This book takes a global perspective in assessing how far we have come - and where we seem to be goinq - with biofuels use in transport. It reviews recent research and experience in a number of areas: potential biofuels impacts on petroleum use and greenhouse gas emissions; current and likely future costs of biofuels; fuel compatibility with vehicles; air quality and other environmental impacts; and recent policy activity around the world. It also provides an assessment of just how much biofuels could be produced in OECD and non-OECD regions, given land requirements and availability, what the costs and benefits of this production might be, and how we can maximise those benefits over the next ten years and beyond.
