I will never forget the date - June 14, 1992 - for as long as I live. On that day, the United Nations Conference on Environment and Development, popularly known as the Earth Summit, came to a successful conclusion in Rio de Janeiro, Brazil.
In March 1990, the UN elected me as chairman of the preparatory committee (prep com) for the Earth Summit. The prep com met five times between March 1990 and April 1992. At the Earth Summit in June 1992, I was elected to chair the main committee. This challenging but important assignment took 27 months to accomplish.
