This report presents findings of research commissioned by the Department of the Environment (DoE), and undertaken by the Impact Assessment Unit (IAU) of the School of Planning at Oxford Brookes University. The research's principal aim is to establish clearly what changes, if any, there have been to the quality of Environmental Statements (ESs), since the earlier DoE-commissioned study covering the period July 1988 to December 1989. The IAU reviewed over 150 relevant literature items, and conducted a targetted survey, by postal questionnaire, of 16 of the most experienced environmental assessment (EA) practitioners in the UK. This provided a guide to the growth of EA activity and ES output, and to the nature and determinants of EA and ES quality. Several key criteria for ES quality were identified, together with several dimensions to be included in a study of ES quality. Changes in ES quality, from 1988-90 to 1992-94, were assessed at two levels: (1) a 'macro study', which classified all projects, for which ESs had been submitted under the EA Planning Regulations before and after 1991, and reviewed 25 ES pairs in detail; and (2) a 'micro study' for ten of these pairs. Research findings were obtained on changes in ES quality, and on what factors led to observed quality improvements. Several recommendations are presented.
