Approximately 20% of the world's annual carbon dioxide (CO2) emissions result from land-use change, primarily deforestation in the tropical regions of Central and South America, Africa, and Asia. These lands are shifting from relatively high-carbon stock natural forests to generally lower-carbon stock crop, agroforestry, grazing, or fuelwood lands and urban areas. While this transformation by land clearing, forest harvest, and fire provides short-term economic benefits and rural livelihood, it is also a major source of greenhouse gas emissions and other social and environmental problems.
However, significant carbon sequestration and greenhouse gas mitigation potential exists in the tropics, and other regions outside the U.S. Most of the sequestration activities identified in the Practices section of this Web site could be implemented in other countries.
This section of the Web site provides information in the following areas to help understand the technical and implementation issues regarding international sequestration opportunities:
