The document summarizes Ecuador's Yasuni-ITT initiative from 2007-2013, which aimed to indefinitely maintain the undeveloped oil reserves of 846 million barrels located in Yasuni National Park in exchange for international donations of $3.6 billion. The park contains exceptional biodiversity and some indigenous communities in voluntary isolation. The initiative sought to avoid environmental and cultural risks of oil extraction while obtaining financial compensation. However, the initiative ultimately received less support than hoped and ended in 2013 with plans for limited oil drilling yet protection of other areas.
