Go green is the need of the hour for survival in all scopes due to the side effects of financial development which has resulted in climate change and environmental damage. Banks can certainly play a proactive role in financial development and ecological preservation. Banks of this kind is named as “Green Banking”. Green Banking (GB) means guaranteeing eco-friendly financial activities and thus the elimination of internal and external carbon footprints. GB initiatives and practices are useful for the environment, banks, and customers. This conceptual investigation attempts to review the literature on GB in the scope of the UAE as far as GB adoption is concerned. It has also proposed an innovative model by integrating the religiosity as an important determinant to the Unified Theory of Acceptance and Use of Technology (UTAUT) in order to capture customers’ intention to adopt GB within the Islamic bank as well as extend the literature and validate the UTAUT model in the GB studies. Overall, studies of GB adoption are still limited and need further investigation, particularly from the Islamic perspective.
