This report has been prepared by the London Environmental Economics Centre (LEEC). LEEC is a joint venture, established in 1988, by the International Institute for Environment and Development (IIED) and the department of Economics of University College London (UCL). Popularly known as "The Pearce Report", this book is a report prepared for the Department of the Environment. It demonstrates the ways in which elements in our environment at present under threat from many forms of pollution can be costed. The book goes on to show ways in which governments are able, as a consequence of this analysis, to construct systems of taxation which would both reduce pollution by making it too costly and generate revenue for cleaning up much of the damage. The book ends with a series of skeleton programmes for progress.
