Green Bonds
As a mortgage provider, NN Bank wants to contribute to the reduction of greenhouse gas emissions in houses, by offering financing options to make homes more sustainable. NN Bank believes that Green Bonds are an effective funding tool to channel financing to projects that have demonstrated clear environmental or climate benefits and contribute to the achievement of the UN Sustainable Development Goals. By issuing Green Bonds, NN Bank intends to align its funding strategy with its mission and sustainability strategy.
Green Bond Framework
In order to address environmental and sustainability challenges where NN Bank can drive positive change, NN Bank has established a Green Bond Framework for issuing Green Finance Instruments to finance Green Buildings. The Framework was first published in June 2021 and since then, Green Bonds have become a significant component of the Bank’s funding mix. To reinforce its sustainability ambitions, NN Bank has decided to update its Framework in February 2024. Under this Green Bond Framework, NN Bank may issue Green Bonds to finance and/or refinance mortgages for energy efficient residential properties in the Netherlands. See NN Bank unsecured funding and NN Bank Soft Bullet Covered Bond Programme webpage for all Green Bond issuances including Final Terms.
