ABSTRACT
This book began with the question of whether voluntary environmental programs work—that is, whether they actually improve environmental outcomes. Breaking the question down further, we have asked: Quantitatively, how large are the gains? Are there significant differences between energy- and nonenergy-related programs? How do participation incentives, as well as the process for setting goals, affect outcomes? How convincing are alternate approaches to baselines and evaluation? We now want to re-examine these questions looking across the seven case studies in this volume.
