The Kyoto Protocol was negotiated in Kyoto, Japan, in December 1997. It was opened for signature on March 16, 1998, and closed a year later. Under terms of the agreement, the Kyoto Protocol would not take effect until 90 days after it was ratified by at least 55 countries involved in the UNFCCC. Another condition was that ratifying countries had to represent at least 55 percent of the worldâs total carbon dioxide emissions for 1990.
Through ratification, the United States agreed to dispose of its unitary chemical weapons stockpile, binary chemical weapons, recovered chemical weapons, and former chemical weapon production facilities by April 29, 2007, and miscellaneous chemical warfare materiel by April 29, 2002.he end of World War II did not stop the development or stockpiling of chemical weapons.
