Comparison · Green Loan vs Sustainability-Linked Loan (SLL)

Green Loan vs Sustainability-Linked Loan

Use a Green Loan when the funds go to a defined, eligible green project. Use a Sustainability-Linked Loan when funding is general-purpose and you want pricing tied to enterprise-wide sustainability KPIs.

The short answer

Both are sustainable-finance instruments, but they work differently: a Green Loan finances a specific green project; an SLL is general-purpose credit whose pricing moves with sustainability performance.

When to use Green Loan

The financing is directed at a well-defined project (renewables, EV fleet, energy retrofit, green building) that can pass EU Taxonomy technical screening and DNSH.

When to use Sustainability-Linked Loan (SLL)

Financing is general-purpose and the borrower wants pricing to reflect enterprise-wide sustainability performance against ambitious, verified targets.

Frequently asked questions

Can a single facility be both?+

Yes — some banks issue 'green SLLs' that combine use-of-proceeds ring-fencing with a KPI-linked ratchet. Both sets of Principles must be satisfied.

Which is more common?+

SLLs have overtaken Green Loans in most European markets by volume because they suit general corporate financing needs.

Do both need external review?+

SLLs require annual independent verification. Green Loans strongly recommend an SPO at origination but external review is not strictly mandatory.
