International Tropical Timber Agreement

The International Tropical Timber Agreement (ITTA), 1983) is an agreement to provide an effective framework for cooperation between tropical timber producers and consumers and to encourage the development of national policies aimed at sustainable utilization and conservation of tropical forests and their genetic resources.
The International Tropical Timber Organization was established under this agreement, which first "opened for signature" on November 18, 1983, then "Entered into force" on April 1, 1985. There were subsequent treaties, with an increasing number of signatories, in 1994 (ITTA2) and 2006 (ITTA3).
ITTA2 (1994) was drafted to ensure that by the year 2000 exports of tropical timber originated from sustainably managed sources and to establish a fund to assist tropical timber producers in obtaining the resources necessary to reach this objective.
It further defined the mandate of the International Tropical Timber Organization. The agreement was opened for signature on January 26, 1994, and entered into force on January 1, 1997.
ITTA3 (2006) aimed to "promote the expansion and diversification of international trade in tropical timber from sustainably managed and legally harvested forests and to promote the sustainable management of tropical timber producing forests". It entered into force on 7 December 2011.
