Sustainability-linked loan

What it means

A sustainability-linked loan is a loan whose interest rate goes down or up depending on whether the company meets agreed sustainability targets, such as emission cuts, a share of renewable energy or workplace safety. The bank thus gives the client a financial incentive to improve its ESG performance.

Unlike a green loan, where the money must be used for a specific environmental project, the proceeds of a sustainability-linked loan can be used for any purpose. What matters is the company's performance against the agreed indicators, not how the money is spent.

The same principle exists for bonds: besides green bonds with earmarked proceeds, sustainability-linked bonds are issued. The market follows voluntary principles that set out how to choose indicators, set targets and verify results.

How it works in practice

The key is choosing indicators that are material, measurable and comparable for the company, such as Scope 1 and 2 emissions, energy use per unit of output or the number of workplace accidents. Targets should be ambitious, going beyond business as usual, otherwise the loan makes little sense.

The company reports regularly on progress, and results are often verified by an independent third party. If targets are met, the loan margin falls; if not, it may rise. The terms are written into the loan agreement much like financial covenants.

For companies that already prepare sustainability reporting under CSRD, gathering the required data is easier. The data used for the loan should be consistent with what the company publishes in its annual or sustainability report.

What to watch out for

Targets that are too easy or indicators that are immaterial may be seen as greenwashing and damage the reputation of both company and bank. Investors and regulators are paying increasing attention to whether sustainable finance actually leads to improvement.

Collecting, verifying and reporting ESG data takes time and money. The interest saving does not always offset these costs, especially on smaller loans. The company should weigh the benefits, including better access to finance and reputation, against the administrative burden.
