Green nanotechnology represents the modern trend in manufacturing systems, which reflects significant development in productivity, cost reduction and competitive advantages. This trend has contributed to changing and responding to many cognitive sciences, including sustainability accounting, in order to keep pace with it and benefit from its advantages. Therefore, the current research aims to conduct an investigation on the role of green nanotechnology in providing the necessary foundations to support the dimensions of sustainable development, and to create effective accounting systems that work on measuring and reporting on that development according to sustainability accounting. The survey included a sample of academics in accounting specialization in a number of Iraqi universities. The analytical descriptive approach was used according to a questionnaire form to achieve the purpose of the research. The research concluded that the repercussions of adopting green nanotechnology could contribute to activating sustainability accounting procedures. By opening up broader areas of focus on relevant accounting information in order to achieve the dimensions of sustainable development in the contemporary business environment.
