Sustainability-Linked Loans

Performance-based lending tied to sustainability KPIs.

Executive summary

Sustainability-Linked Loans (SLLs) are general-purpose credit facilities whose pricing moves with the borrower's performance against material, ambitious sustainability targets. Governed by the LMA / APLMA / LSTA Sustainability-Linked Loan Principles, they are today the dominant sustainable-finance instrument for corporates and, increasingly, SMEs.

Any loan that ties financial terms to the borrower's performance against ambitious, material and externally verified sustainability targets, in line with the Sustainability-Linked Loan Principles (SLLP) published by the LMA, APLMA and LSTA.

Key concepts

KPI

The metric on which performance is measured — typically absolute Scope 1+2 tCO₂e, energy intensity, or a sector-specific indicator.

SPT

Sustainability Performance Target — the calibrated, benchmarked trajectory the borrower commits to, verified externally each year.

Margin ratchet

The two-way pricing adjustment applied when SPTs are met or missed. Under the SLLP, both directions are expected.

External review

A Second Party Opinion at origination and annual verification post-drawdown, delivered by an independent reviewer.

Glossary terms

Frequently asked questions

What is the difference between an SLL and a Green Loan?+

A Green Loan finances a specific eligible green project (use-of-proceeds). An SLL is general-purpose credit whose pricing is linked to sustainability performance, regardless of what the money is used for.

Who verifies the SPTs?+

Under the SLLP, borrowers must obtain independent verification of KPI performance at least once a year. Redigo Carbon partners with Audelya, whose network of independent reviewers provides the Second Party Opinion and annual verification.

Do SPTs need to be ambitious?+

Yes. The SLLP require targets to be material to the borrower's business and ambitious beyond a business-as-usual trajectory, typically benchmarked against a science-based pathway or a recognised sectoral reference.
