As climate geoengineering (CE) research moves from modelling and laboratory studies to field experiments, there is a need to move from transparency in principle to transparency in practice. The objective of this paper is to focus attention on two distinct roles that disclosure-based governance is anticipated to play: minimization of the potential for environmental and social concerns associated with CE research; and to generate and maintain legitimacy in the research process itself. Disclosure-based governance must recognize the iterative and inherently normative nature of CE governance and support the development of a decentralized system of disclosure serving multiple ends.

CIGI Papers present in-depth analysis and discussion on governance-related subjects. They include policy papers that present CIGI experts' positions or contributions to policy debates, and background papers that contain research findings, insights and data that contribute to the development of policy positions.
