This book analyses some key issues relative to environmental legislation in the United Kingdom and Belgium such as: environmental competences, environmental permits and building permits, environmental liabilities, environmental levies, subsidies and policy agreements. It is obvious that these areas are not only relevant to academics, but also to those who are, on a regular basis, confronted with the existence, application and enforcement of environmental legislation: business people, lawyers, consultants and civil servants. This study compares two legal systems with a completely different background (civil law versus common law) and indicates how one system might benefit from elements embedded in the othersystem. Secondly (for business people, consultants, lawyers in Europe), it gives practical information about environmental legislation relevant to companies operating in Belgium and/or the United Kingdom.
