Dipli has introduced the Dipli Circular Index (DCI), a metrics-based framework designed to quantify how far European markets have advanced towards circular smartphone models. Developed with Ipsos for the 2025 study, the DCI offers the “compass” long sought by telecom operators, OEMs, and retailers to compare countries and scale circular strategies. Built on responses from more than 4,000 consumers in France, Germany, the United Kingdom and Poland, it gives the ecosystem a common yardstick to turn vision into execution.

The DCI blends two equally weighted pillars, a Trade‑in Index and a Refurbished Index, and scores them through four consumer‑centred lenses: actual adoption, quality of experience (satisfaction), advocacy (NPS as a proxy for trust), and near‑term intent (consideration). For the first time, industry players can view “circular readiness” by country, spotlighting where behaviour and sentiment already support circular models and where the gaps remain.

Three practical advantages stand out. First, it locates each market on a clear maturity curve, revealing what audiences do today and what they might embrace next. Second, it diagnoses barriers and growth levers to guide investment, from improving trade‑in journeys to raising confidence in refurbished quality. Third, it enables year‑on‑year tracking so progress becomes measurable and accountable. Early findings show distinct maturity levels across the four countries, offering a roadmap for prioritising actions and accelerating the shift to circularity.
