Financing the Circular Economy Has Its Own KPIs
Circular business models carry systemic, multi-counterparty risk — financing them on single-asset plant logic misprices that risk.
While renewable energy established a blueprint for sustainable finance centered on a single asset, a predictable output, and a straightforward metric, that model fails when applied to circularity. Rather than constructing a facility, calculating megawatt-hours, and discounting cash flows, circular business models demand an entirely different approach.
Circular business models rely on a coordinated network of counterparties operating together over time. This requires reliable reverse logistics, customers who return products, and suppliers adapting their sourcing terms. Consequently, both revenue generation and risk exposure reside within this ongoing systemic coordination. Treating circular models like traditional plant infrastructure focused on one output metric and a single counterparty fundamentally misprices the underlying risk.
The KPI set has to follow the risk. Material recovery rate and residual value retention matter more than volume produced. Return and reuse rates indicate whether the loop is closing in practice. Revenue under a leasing or service model needs durability and renewal-rate underwriting. And because performance depends on multiple parties, counterparty risk deserves the same weight as asset risk.
Empirical evidence highlighting this gap is provided by research from Circle Economy. Tracking global investments in the circular economy from 2018 to 2023, its Circularity Gap Report Finance highlights a divided capital market: the absence of universal metrics and standards creates difficulties for investors attempting to evaluate circular ventures, while simultaneously preventing circular enterprises from accessing suitable funding.
In its latest Circularity Gap Report, the organization introduces a critical strategic pivot for executive leadership: in addition to evaluating secondary material flows in tonnes, it introduces the "Value Gap": quantifying global monetary losses from linear business models at tens of trillions of euros annually. Crucial for effective capital deployment, this redefinition transitions circularity from a standard sustainability metric into a quantifiable financial opportunity. To align performance metrics successfully, credit and underwriting teams must adopt this framework shift.
Circularity simply carries a distinct risk profile. Using traditional plant-financing logic is a mispricing of risk. Ultimately, financing the circular economy requires underwriting the broader system instead of a single plant.
