This research examines conditions under which environmental regulatory disclosure is more versus less likely to work, with focus on the case of the Philippines. Two major findings arise out of a case study. First, we observe a mismatch between the nature of information and the main addressees of the disclosed information, which led the operation of the subject disclosure program to deviate from its targets. Second, this institutional deficiency has to do with the organizational culture and routine practice of the implementing agency. The second finding challenges a major justification of information-based environmental regulation (IBER) administered in weak states and underscores the role that administrative capacity plays in making novel regulations come into effect. Contrary to the popular belief that IBER creates non-governmental forces that offset a limited statehood, it may be less likely to work where state administrative capacity is weak.
