Borgese moved to Chicago with her husband, who taught at the University of Chicago. With Richard McKeon and Robert Hutchins, G. A. Borgese formed the interdisciplinary Committee to Frame a World Constitution, which published a Preliminary Draft of a World Constitution in 1948. The members of the Committee at the time of the publication of the Draft were, in addition to Hutchins and Borgese, Mortimer J. Adler, Stringfellow Barr, Albert Léon Guérard, Harold Innis, Erich Kahler, Wilber G. Katz, Charles Howard McIlwain, Robert Redfield, and Rexford Tugwell. Elisabeth was the secretary of the Committee and edited its journal, Common Cause, which was published by the University of Chicago Press from 1947–1951. In 1952, G. A. Borgese died in Fiesole, Italy. In the mid-1960s, Mann Borgese worked as an editor, researcher and translator in Chicago.

Elisabeth lived with psychiatrist and writer Corrado Tumiati (1885–1967) from 1953 until his death in 1967.

She wrote extensively on topics including peace, disarmament, human rights, world development, and the Law of the Sea. When the Constitution of the World was republished in 1965, Elisabeth Mann Borgese provided a critical introduction. In 1967, she began to focus specifically on marine law, working with Wolfgang Friedmann and Arvid Pardo, then Malta's Ambassador to the United States.
