In 2004, ExCom instructed UNHCR to pay particular attention to situations of protracted statelessness and to explore, in cooperation with states, measures that would ameliorate and end these situations. In 2006, it provided UNHCR with more specific guidance on how to implement its mandate. The Conclusion on Identification, Prevention and Reduction of Statelessness and Protection of Stateless Persons requires UNHCR to work with governments, other UN agencies, and civil society to address statelessness. UNHCR's activities are currently categorized as identification, prevention, reduction, and protection.
