The convention (the signed document of international agreement) guiding the work of the World Heritage Committee was developed over a seven-year period (1965–1972). The United States initiated the idea of safeguarding places of high cultural or natural importance. A White House conference in 1965 called for a "World Heritage Trust" to preserve "the world's superb natural and scenic areas and historic sites for the present and the future of the entire world citizenry". The International Union for Conservation of Nature developed similar proposals in 1968, which were presented in 1972 at the United Nations Conference on the Human Environment in Stockholm. Under the World Heritage Committee, signatory countries are required to produce and submit periodic data reporting providing the committee with an overview of each participating nation's implementation of the World Heritage Convention and a "snapshot" of current conditions at World Heritage properties.
