In addition to his mediation roles, Kheel wrote a multi-volume text on labor law and the popular book
The Keys to Conflict Resolution: Proven Methods of Resolving Disputes Voluntarily. He was also widely involved with such philanthropic organizations as the Gandhi Society for
Human Rights, and in the
civil rights movement in the 50s and 60s where he served as Executive Director of the
National Urban League during the term of NUL President
Lester Granger. Kheel was one of the principals in
Tom Mboya's efforts of the late 50s and early 60s to organize the "Airlift Africa" project that ultimately brought some 230 African students to the U.S. over the period 1960–63 to study on scholarship at Class I accredited colleges. Among these students was President
Barack Obama's father,
Barack Obama, Sr. who later settled in Hawaii where President Obama was born. Kheel was one of the lead developers of the
Puntacana Resort and Club in the
Dominican Republic. to help resolve the continuing conflict between environmental protection and economic development. Kheel's commitment to sustainable development was wide and consistent. He created the Earth Times during the process leading to the 1992 Earth Summit in Rio de Janeiro, which preceded the 1997 Kyoto summit whereby more than 100 countries signed the Kyoto protocol and committed to reduce the emissions of carbon dioxide. To promote the Rio summit Kheel enrolled the help of his friends and client artist Robert Rauschenberg to create a poster named the Earth Pledge, which was signed by hundreds of Heads of state, ambassadors, delegates, and prominent dignitaries. The Earth Pledge was widely promoted during the summit, and applauded by Secretary General Maurice Strong. The proceeds of the sale of Rauchenberg's artwork were used to start the Earth Pledge Foundation, which went on to become an incubator of early stage sustainability solutions in the waste, architecture, fashion, and food systems, with projects that significantly accelerated the adoption of sustainability solutions in New York city. The Earth Pledge Foundation was managed by Kheel's protégée and environmental activist Leslie Hoffman from 1994 until 2011.
