Spanish energy giant Iberdrola wrapped up what it billed as “the world’s largest sustainable finance transaction to date” with the signing of agreements covering €5.3bn ($6.55bn) of ‘green loans’ with 24 institutions.

Iberdrola agreed the extension of two multicurrency syndicated loans totaling €4.4bn and their expansion by €900m in an agreement that links the terms of the finance to Iberdrola’s performance in reducing emissions.
