Social evaluation of natural resource projects in rural areas of Iran, which has certainly numerous positive and negative impacts, can have an important role in identifying the strengths and weaknesses and improving the implementation process of such projects in the future. The purpose of this research is the social evaluation of the Hosseinabad carbon sequestration project in South Khorasan using the network analysis method to investigate the level of trust formed between the people and the organizations involved in the implementation of this project. According to the results of this study, the evaluation of different trust network indicators showed the formation of a coherent and integrated network among the beneficiaries of the project. The formation of trust indicates the positive impact of the project executives on the local people's perspective and promises to provide a suitable environment for the implementation of natural resource projects in this area. A study of the power distribution among organizations also shows that out of the 44 organizations studied, most of the power is owned by about 10 organizations, which is one of the weaknesses of this project and it is suggested to distribute the relationships based on uniformity. Confidence in the entire network with proper planning and policy reduced the focus of power in one or more limited organizations.
