Environmental Impact Bond (EIB)

An EIB is an innovative and alternative financial tool designed to foster social innovation practices in the public sector. As such, EIBs are financial models designed with a focus on environmental interventions, whereby public agencies work together with private capital and nonprofit organizations to fund costeffective solutions. The public entity pays a return to investors only if the intervention meets or exceeds previously agreed-upon performance targets or outcomes.
EIBs differ from green bonds with respect to the fact that an EIB is a pay-forperformance (or pay-by-results) tool, in which the payment is based on realized measured benefits, whereas green bonds fund a project based only on planned actions. Therefore, EIBs are characterized by a direct linkage of environmental-tofinancial benefits.
An EIB (Environmental Impact Bond) is a variant of an SIB (Social Impact Bond) both of which are included in the broader category of IBs (Impact Bonds).
