“Green bonds enable Digital Realty to align its sources of capital funding with its global sustainability goals. Our green bonds complement our sustainability-linked global credit facility, enhancing our ability to support our customers as they grow and scale, which helps to ensure a greener future for all,” said Aaron Binkley, VP of Sustainability at Digital Realty.

Beyond green bonds, Digital Realty is committed to sustainability through initiatives such as joining the Science-Based Targets initiative (SBTi) in 2020. As part of this commitment, Digital Realty aims to reduce its Scope 1 and 2 emissions by 68% and Scope 3 emissions by 24% by 2030.
