The article discusses how greenhouse gas emissions contribute to climate change and how the Clean Development Mechanism (CDM) can help reduce these emissions. The focus is on the potential for implementing CDM projects in Tanzania, specifically in the area of Land Use, Land Use Change, and Forestry (LULUCF). The researchers examined the economic feasibility, institutional requirements, and potential for sustainable development of LULUCF CDM projects in Tanzania. A case study was conducted in Mwanza to gather data and assess different scenarios. Key findings include the need for more CDM projects in Africa, particularly in the LULUCF sector, and the potential benefits of such projects for both the environment and local communities.
