Given that resources—particularly financial, human, and technical—are indeed limited, it is essential for companies to evaluate the opportunities and threats associated with each CCS technology in order to allocate these resources effectively to research and development (R&D) projects. This research specifically focuses on prioritisation and resource allocation, presenting a fuzzy multi-criteria group decision-making methodology that was successfully applied to assess the development opportunities for CCS technologies at the Pars Special Economic Energy Zone (PSEEZ). In fact, the proposed methodology serves as a systematic and effective decision support tool, thereby enabling decision-makers to prioritise and select the most attractive technologies, where the attractiveness of each technology is defined by the associated opportunities and threats inherent in its acquisition and development. https://jogpt.pgu.ac.ir/article_239129_fc2926439ea54ea120f0f18158fa12ed.pdf
