The Circularity Indicators Project provides companies with a methodology and tools to assess how well a product or company performs in the context of a circular economy, allowing companies to estimate how advanced they are on their journey from linear to circular.

Update: September 2019

We are currently developing the Circularity Score, a company-level assessment tool which allows companies to:

  • Highlight the proactive efforts they make to capture circular economy business opportunities through strategic prioritisation and innovation
  • Provide a ‘snapshot’ of the circularity of their material flows and service models as they are today
  • Understand the most important development areas to concentrate on with the guidance of an analyst commentary

The Ellen MacArthur Foundation wants to celebrate success stories by creating inspirational case studies based on the scores. The best-performing companies will be invited to join a list of front runners to celebrate their achievements and inspire others. More details will be confirmed in due course.

The company-level Circularity Score can work in parallel with the product-level Material Circularity Indicators (MCI). MCI data can be used for Circularity Score material flow related indicators, but the Score will cover a broader picture of a company’s circularity.

Receive updates on Circularity Score as we near the launch of an online platform in early 2020.

Companies increasingly see opportunity in circular economy business models, which allow them to capture additional value from their products and materials, and mitigate risks from material price volatility and material supply.

The developed indicators consist of the Material Circularity Indicator, measuring how restorative the material flows of a product or company are, and complementary indicators that allow additional impacts and risks to be taken into account.

The indicators may be used by product designers, as well as for internal reporting, procurement decisions, and the evaluation or rating of companies.

Circularity Indicators web tool

Together with the methodology, the project has contributed to the development of a commercially-available web-based tool that will provide businesses with the means to track their progress and ensure that their products fit a circular economy based business model.

The Circularity Indicators tool has been developed by Granta Design, and integrated with the MI:Product Intelligence package, which enables users to analyse and evaluate a range of environmental, regulatory, and supply chain risks for their designs and products.

With MI:Product Intelligence, users can either import, build and edit bills of materials for products or designs through an easy-to-use web app, MI:BoM Analyzer, or they can work within a CAD system. In either case, users can run reports that analyse bills of materials in order to assess product risk and guide design decisions. As a result of the Project, a new Circularity Report, based on the methodology referred to above, is available in the web app. The Circularity Report analyses environmental, regulatory and supply chain risks alongside the Material Circularity Indicator.

The team

The project was executed by the Ellen MacArthur Foundation together with Granta Design, the world leader in materials information technology. It has been co-funded by the LIFE financial instrument of the European Union.

As part of the project, the methodology was tested by a group of leading European businesses with real product data to ensure its robustness and relevance economy-wide. In addition, several other stakeholders from investors, regulators, consultancies, and universities were involved in the project through virtual and in-person workshops to help refine the developed measurement approach.
