UNDRESS CIRCULARITY

Measuring Circular Impact - Methodology and Guide for Practitioners

An assessment of the electronics industry in Germany

  • April 24, 2025

This new report introduces the Circular Business Model Impact (CBMI), the first practical methodology to measure the real environmental impact of circular business models – focusing on the product use phase. Developed by Circularity in cooperation with Deloitte, Fraunhofer IZM, Systemiq and 12 industry partners, the report provides both industry insight and a practical step-by-step guide for companies to apply the methodology.

What to expect from this report

The report provides a practical, real-world methodology to evaluate circular business models – based on actual usage behavior of B2C and B2B customers that was captured first time for this work.

It covers the following key topics:

  • A new approach to evaluating the impact of circular electronics business models
  • Real-world insights into how electronic devices are used, repaired and reused
  • Practical guidance for companies that want to make impact measurable

What to expect from this report?

  1. A New Way to Measure Circularity
    The UNDRESS Circularity project introduces the CBMI methodology—a robust, data-driven framework to assess the environmental impact of circular business models (CBMs), accounting for real-world use and consumer behavior.
  2. Tackling the Use Phase Blind Spot
    Unlike existing assessment frameworks, the CBMI method zooms in on the often-overlooked use phase of products, analyzing how CBMs affect user behavior and its environmental effects.
  3. Circular Electronics Are Still Emerging
    Only 19% of users in Germany own second-hand electronics, and just 1% have rented devices—highlighting the untapped potential for circular models. However, in the case of a smartphone for example, circular business models can only mitigate about 50% of yearly emissions. The remainder must be adressed by product design, production and end-of-life strategies.
