The European Central Bank has decided to extend the use of climate factors in the Eurosystem collateral framework to certain eligible credit claims where the debtor is a non-financial corporation, aiming to bolster risk management around uncertainties tied to the green transition.

The move builds on a climate factor introduced for marketable assets issued by non-financial corporations, approved in July 2025 and taking effect on June 15, 2026. The ECB said collateral pledged in Eurosystem refinancing operations could face unexpected climate related transition shocks, such as shifts in climate policy, technology, consumer behavior, litigation, or broader macroeconomic adjustments.

Under the framework, the ECB will apply reductions to the value of collateral with higher sensitivity to climate uncertainties. The climate factor will be calculated using an asset level uncertainty score that incorporates a sector level stressor from the latest Eurosystem climate stress test, the debtor’s exposure to transition related uncertainties, and the residual maturity of the credit claim.

The ECB said the maximum additional reduction in final collateral value, covering both bonds and credit claims, will be 5%. It also noted that climate factor values for individual credit claims will not be publicly disclosed and is targeting implementation at the earliest by the end of 2027, with annual updates using the latest climate related data.
