This is a pathbreaking account of how the environmental movement has led to profound changes in the perceptions and practices of large-scale corporations, as shown here in the chemical and petroleum industries. The book traces how market, social, and political pressures drive corporations to respond to environmental issues, analyzes the cultural frames that organizations use to come to terms with these external influences, and describes the resulting changes in organizational culture and structure. For this expanded edition, the author has written a new chapter that brings his original assessment up to date, expands and modifies the model and data used in the original edition, and offers a broad picture of the current state of corporate environmentalism and where it is going.
