What is it?

The Circular Transition Indicators (CTI) are a collection of metrics that measure various aspects of circularity.

Which problem does it solve?

CTI solves two problems on two different layers:

1. CTI creates transparency about the circularity of a defined entity (product, process, factory, company …)
2. CTI enables a comparison of metrics across entities and industries

Who should be involved?

CTI aggregates data from the organisation’s material flow. Therefore, the most relevant functions are Procurement, Logistics, Operations, and Waste Management. Product development, sustainability, and accounting experts will most likely be needed.

How does it work?

The suggested CTI process has seven steps:

1. Scope: Determine the boundaries
2. Select: Select the indicators
3. Collect: Identify and collect the sources
4. Calculate: Perform the calculations
5. Analyze: Interpret results
6. Prioritize: Identify opportunities
7. Apply: Plan and act

This can be followed by another loop to measure progress.
