Some kinds of research dealing with environmental problems are faced with the need to measure the relative qualities of different environmental situations. The assessment of environmental impact for resource development projects (including the no-build alternative) when alternative locations are considered implicity involves a comparison of the qualities of different environments. Russell Train, Head of the EPA, has made a plea for the development of environmental indices. There have been a number of attempts to quantatively rank or rate environmental situations. Economists are emphasizing the need to objectively measure the value of environmental attributes, and considerable work has been done in trying to understand the way in which people perceive environmental attributes.
