Revealing how Europe is shifting to circular tech

The Dipli Circular Index is a strategic tool that measures how mature and ready a market is to embrace trade-in and refurbished models. Designed as a true compass for circularity, helping businesses

The Dipli Circular Index (DCI) measures circular maturity across France, Germany, the UK, and Poland based on insights from over 4,000 respondents.

Each country's score out of 100 combines two equally weighted components, the Trade-in index and the Refurbished index, built around four dimensions of the customer journey: adoption, satisfaction, NPS, and consideration.

 

💡 This dual framework provides a clear, comparable view of circular engagement across European markets.
