Toward Carbon Accounting and Circular Harmony in Shipping Corporations: A Systematic Bibliometric Review

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines how carbon accounting can be used to govern, not merely report, circular economy principles in shipping corporations. Grounded in institutional theory and aligned with the UN 2030 Agenda, this study introduces circular harmony as an accounting design principle: Circular interventions are embedded in a single well‐to‐wake ...
