This article assesses the impact of the Aarhus Convention, a key international agreement for promoting public participation, over the past decade. It evaluates the roles of civil society organizations, national governments, and international bureaucracies in advancing the Convention's principles, particularly within the international climate regime. The review finds that while stakeholders and secretariats have successfully increased awareness about participation issues, the implementation of Aarhus principles in climate negotiations often leans towards domestic solutions, such as including civil society representatives in governmental delegations, rather than integrating these principles into international negotiation strategies.
