This guidebook aims to help companies identify the stakeholders in their supply chain and recognize the effects their transition to reuse business models may have on them. It is intended to be a guide, as part of a learning process, to ensure the transition to a reuse model, a component of the circular economy, is equitable and just. The guidebook takes companies through three steps of identifying who their stakeholders are, what effects are felt by these stakeholders, and target setting to mitigate risks to these stakeholders and identify partners to support a transition to an equitable reuse business model.
