Following the retirement of Sérgio Duarte in February 2012, Angela Kane, then USG for Management, was appointed as the new High Representative for Disarmament Affairs.

UNODA supports the development and implementation of practical disarmament measures after a conflict, such as disarming and demobilizing former combatants and helping them to reintegrate in civil society.

It supports and participates in multilateral efforts to strengthen the non-proliferation of WMD and in this connection cooperates with the relevant intergovernmental organizations and specialized agencies of the United Nations system, in particular the IAEA, the OPCW and the CTBTO PrepCom.

The CAB focuses its efforts in the conventional field (all weapons not considered WMDs, including small arms and light weapons) of promoting transparency and confidence-building, curbing the flow of small arms in regions of tension, and developing measures of practical disarmament.

The IO Branch organizes a wide variety of special events and programmes in the field of disarmament, produces ODA publications such as the Disarmament Yearbook and occasional papers, and maintains the databases for specialized areas such as Register of Conventional Arms, Status of Treaties and Article 7 - Mine-Ban Convention.
