The ATT Network was launched in September 2013 by the Geneva Forum and GCSP. Since May 2015, it is composed of: the Centre on Conflict, Development and Peacebuilding (CCDP), the GCSP, Small Arms Survey, and UNIDIR. It acts as a platform to exchange information, elaborate and provide practical guidance on ATT implementation, build related capacities and implementation resources, develop networks among implementation actors and communities, and help states preparing for ATT follow-up meetings. The Network is inclusive, informal, and works through activities such as thematic public meetings, training workshops, working group discussions, and the production of implementation guidelines.
