ABSTRACT
As environmental policymaking has matured, information-based policy instruments and transparency issues have been gaining a prominent role. As one such instrument, reporting standards do not demand a particular environmental performance from their targets, but instead ask for the provision of information about environmental performance. The central idea behind reporting is that such information is valuable for the targets themselves-for instance because it allows them to identify strengths and weaknesses in their environmental performance-as well as for a variety of stakeholders who can sanction poor and reward good environmental performance.
