The circular carbon economy (CCE) approach, developed during Saudi Arabia’s G20 Presidency and endorsed by G20 leaders and energy ministers, can be used as a framework for holistic assessments of all available energy and emission management technologies within the confines of a global carbon budget. KAPSARC’s Circular Carbon Economy Index project, launched in 2021, will develop a composite indicator (index) that measures and tracks country performance and potential on various dimensions of the CCE to support related policy discussions and planning.
