R&DI institutions have adopted solutions based on Portfolio Management Project (PMP) to select the best projects in terms of both cost and strategic results. The candidate projects must meet sustainability requirements, since investments in sustainability have emerged as the most important global issue for business, industry, government, and academia. The objective of this research was to develop a conceptual model for analyzing a portfolio of sustainability projects. Such a portfolio provides descriptors widely recognized to support technology transfer, notably in the agricultural domain. This conceptual model was developed from a case study of Embrapa (Brazilian Agricultural Research Corporation). Although the proposed model has become a simple tool, the results revealed it is interesting for reclassification of the Embrapa’s projects, pointing to solutions on sustainability with a potential for technology transfer.
