UNITAR is entrusted with a key set of responsibilities within the United Nations Organization in convening high-level meetings for the UN Secretary-General.

In order to benefit from the presence of the Special Representatives of the Secretary-General participating in the SRSG Seminar, UNITAR has been requested by the Department of Peacekeeping Operations (DPKO) with the Department of Field Support (DFS), and the Department of Political Affairs, to facilitate the coordination of their respective internal Heads of Mission Conferences which take place immediately following the Seminar. The three Departments play a key role in UN operations worldwide.

In partnership with the United Nations Office at Geneva (UNOG), UNITAR has launched the Geneva Lecture Series, a series of conferences open to the public that are held at the UN in Geneva. Each lecture invites internationally recognized personalities to engage with the public to address pressing global challenges faced by the international community.
