How do sustainability-linked loans work?
Translate sustainability objectives into measurable loan terms, evidence and ongoing reporting.
A sustainability-linked loan links specified financing terms to the borrower's achievement of material sustainability performance targets. The structure should define relevant KPIs, ambitious targets, calculation methods, baselines, pricing consequences, reporting and independent verification. The Loan Market Association principles are a primary market reference; transaction terms remain mandate-specific.
Core structure
The financing can support general corporate purposes while using contractual sustainability KPIs and targets. Borrowers, lenders and advisers should document data ownership, methodology changes, acquisitions or disposals, target recalibration, reporting dates and the consequences of missing information.
