Abstract
This study examines how Nigeria’s upstream oil and gas decarbonisation agenda is interpreted and implemented by manufacturing firms embedded within the Port Harcourt industrial cluster. While national policy and operator-level strategies place emphasis on emissions reduction and technological innovation, limited empirical attention has been given to the value chain involvement, how decarbonisation pressures is interpreted across extended supply chains, particularly in relation to Scope 3 emissions. Through a multi stakeholder approach involving other actors in the value chain (international oil companies (IOCs), Multinational oil companies (MNCs), National oil companies (NOCs), manufacturing companies in Port Harcourt, policy makers and regulators), this research based its theoretical framework on Technology–Organisation–Environment, Diffusion of Innovation theory, and Stakeholder Theory, while adopting a pragmatic convergent mixed methods design. An ongoing online survey structured with open-ended and closed-ended questions administered through JISC captures quantitative patterns in decarbonisation adoption, while the scheduled semi-structured interviews explore governance dynamics and organisational responses in greater depth. Although the survey is ongoing, preliminary findings show an insignificant low-carbon drive in procurement activities or decarbonisation pressures alongside significant infrastructural and financial constraints. By repositioning manufacturing firms as active intermediaries in Nigeria’s energy transition journey, the paper contributes to academic knowledge on value chain governance, industrial sustainability, and low-carbon transitions in resource-dependent economies.
