The Circular Carbon Economy (CCE) Index is a tool for energy and climate policymakers and stakeholders to quantify and compare country performance and potential for reaching CCEs. The index measures and benchmarks major economies and oil-producing countries on two temporal dimensions: The CCE Performance sub-index measures countries’ current performance on the various CCE activities (e.g., energy efficiency, renewable energy, fuel switching, or carbon capture and storage). The Enablers sub-index gauges how countries are positioned to progress toward the CCE based on key enabling factors.
