This report explores the multiple roles and potential of CSOs in international policymaking and examines the strengths and weaknesses of CSOs and state-based organizations in global governance. It looks particularly closely at the resources, access, skills and experience that each group of actors brings to the table. It concludes that the infrastructure used to incorporate CSOs into the United Nations and other multilaterals must be strengthened and expanded if more integrated and effective forms of collaboration are to be developed and outlines policy recommendations how this goal can be accomplished.
