This text examines the impact of environmental policy and law on the energy sector in the European Community, the US and Canada. It compares jurisdictional contexts, timing, application, instrument choice, and relative openness of the three regimes as they impact upon the energy sector. A major theme is the influence of US environmental law doctrines and approaches. The analysis includes oil and gas exploration, production, processing and transportation and non-nuclear electricity generation and transmission. The energy sector is a significant source of air and water contaminants, as well as a major land user. It is also a considerable contributor to urban smog problems, acid rain and disposal of toxic waste, as well as to the global problems of ocean pollution and the greenhouse effect. Consequently the energy sector feels the effects of new and more stringent environmental standards, and it is these effects which these books seek to examine in depth, with helpful references to the key legal materials and leading judicial decisions.;This book is intended for practising lawyers, corporate environmental advisers, energy consultants, public officials and academic lawyers interested in energy and the environment. Readership will be on both sides of the Atlantic.
