What is the history of the UN emblem?

The emblem of the United Nations was approved by General Assembly resolution 92 (I) of 7 December 1946. 

Description:  The design is "a map of the world representing an azimuthal equidistant projection centered on the North Pole, inscribed in a wreath consisting of crossed conventionalized branches of the olive tree, in gold on a field of smoke-blue with all water areas in white. The projection of the map extends to 60 degrees south latitude, and includes five concentric circles" (A/107).

Symbolism: The olive branches symbolize peace. The world map depicts the area of concern to the United Nations in achieving its main purpose; peace and security.
