The issue of'sustainability'in the developed world is nowhere more critical than in the field of personal travel, which in many countries has become the fastest-growing contributor to global warming. Unless the use of cars can be brought under control, there is little chance of meeting government targets for reducing greenhouse emissions. Personal Transport and the Greenhouse Effect sets out the steps that could be taken to lessen the conflict between personal mobility and long-term environmental security. It provides a detailed analysis of the policy options available for limiting carbon dioxide emissions, and highlights the limitations of technological measures in solving the problem. Instead, the book's 12-point plan for sustainability shows how a significant reduction in emissions requires the use of all the policy measures available. This valuable contribution to a crucial area of debate covering energy, transport policy and the environment will be essential reading for policy makers, planners and students alike. Peter Huges is deputy editor of Local Transport Today, and has contributed to a wide range of publications including The Daily Telegraph, The Guardian, New Scientist and Energy Policy.

Ethanol production in the United States totaled almost 5 billion gallons in 2006, about 1 billion gallons more than in 2005. While this was a significant increase, further expansion in the industry is continuing, with production expected to exceed 10 billion gallons by 2009. This large and rapid expansion of U.S. ethanol production affects virtually every aspect of the field crops sector, ranging from domestic demand and exports to prices and the allocation of acreage among crops. Many aspects of the livestock sector are affected too. As a consequence of these commodity market impacts, farm income, government payments, and food prices also change. This book examines the economics of ethanol production and its impact on food prices and greenhouse gas emissions.
