This review, initiated by the NSW Circular’s Government Taskforce and conducted via a collaboration between the Institute for Sustainable Futures (UTS), the University of Newcastle, the University of Sydney, UNSW Sydney, and Macquarie University, investigates the methods, tools, and data that could be applied to measure the GHG emissions implications of a CE in NSW.

Global case studies were collected using desktop research of those methodologies that have been applied by policymaking agencies to benchmark and monitor the GHG implications of CE initiatives. These case studies were then compared to the requirements identified in workshops with NSW policy, research, and industry stakeholders.
