The projected carbon benefits are 75 Mt C over the lifetime of the projects. It has accepted 14 forestry projects and one soil carbon management project as of February 2000. Estimated total carbon benefits over the lifetimes of eight projects in at least initial implementation stages are about 13 Mt C rising to 25.5 Mt C if the projects are fully funded and implemented on 1.27 Mha. Some projects have been designed that could expand across whole regions. The Scolel Te project in southern Mexico has initiated agroforestry activities on about 150 small farms.
Projects offer varying rates of carbon benefits over time.
Projects summarized in Table 5-2 have reported project lifetimes ranging from 16 to 99 years, averaging 41 years. These projects appear to deliver carbon benefits quickly relative to other project types, however, by annually avoiding high losses of carbon stocks per hectare of mature forest.
