This policy discussion paper is intended to stimulate debate about how to develop more and better opportunities for formal and nonformal environmental education for British adults. A summary found at the beginning of the paper lists its implications for the government, all providers of adult education, all providers of work-related training, businesses, the voluntary sector, and the National Institute of Adult Continuing Education. The paper considers the case for environmental adult education, reports on the level and kinds of activity that currently exist, and identifies a series of developments that are desirable and necessary steps in the transition to a more sustainable society, using government legislation and responsible individual, workplace, and community action as appropriate. In the belief that practices of educational organizations should act as examples, the paper also considers the process of institutional change. Contains 14 references. (YLB)
