The Material Circularity Indicator (MCI)

What it is

Material Circularity Indicator (MCI) is an assessment tool for companies to improve product design and material procurement. The MCI tool:

  • Measures the circularity of material flows for selected products
  • Allows companies to build from products to portfolios, and can be extended to a company level view on the circularity of material flows
  • Supports decision making on product design and material procurement


How MCI and Circulytics complement one-and-other

The company-level Circulytics and the product-level Material Circularity Indicator (MCI) are complementary as they address different needs, but with the same dataset. MCI data, when available on a company or on a business unit level, can be applied to the Circulytics material flow related question indicators.

World Business Council on Sustainable Development (WBCSD): Circular Transition Indicators (CTI)

What it is

CTI is a self-assessment framework for companies to help them understand the circularity performance of their material flows and energy consumption. It also looks at the use of critical materials and circular material productivity. The online CTI Tool (coming soon) offers self-assessment and enables companies to map their own circular journey by monitoring progress against self-set targets in an annual monitoring cycle.

CTI allows companies to:

  • Decide the assessment scope in terms of the entire company, a business unit or production facility.
  • Decide the appropriate time frame based on use, which could be e.g., annual following a company’s reporting cycle or 10 years for a large CAPEX investment.
  • View an online dashboard that allows companies to update data and see results in real time

These elements enable CTI to be used in scenario planning, and in future comparison against industry/country circular performance when data becomes available. They are also useful in having informed discussions with suppliers and customers.

Other benefits and more details are available directly from WBCSD and via their website.


How Circulytics and CTI complement one-and-other

The Foundation and WBCSD have worked together to ensure the greatest viable degree of alignment as to how we collectively define and measure circular economy for companies. Importantly, the definitions and the ways each method measures material flows have been aligned so that companies can use the same datasets if they choose to use both tools.
