Acknowledgments

This report reflects the efforts of many people, both inside and outside of companies, who seek to improve the environmental performance of business. Without them there would be no report. We thank them for their contributions and wish them much success as they strive to make this a better world for us all. It also builds on an earlier paper, "Corporate Environmental Performance Indicators: Bridging Internal and External Information Needs," by Daryl Ditz and Janet Ranganathan presented at the 1996 Fenner Conference on the Environment, Tracking Progress: Linking Environment and Economy Through Indicators and Accounting Systems, in Sydney, Australia.

We are indebted to the Andrew W. Mellon Foundation for providing major funding for this work, and to the many colleagues and friends who freely gave of their time.
