CyrusOne Publishes 2023 Sustainability Report

CyrusOne, a leading global data center developer and operator specializing in delivering state-of-the art digital infrastructure solutions, published its 2023 Sustainability Report, highlighting the company's commitments to the environment, the community, and stakeholders. The annual report provides insight into CyrusOne's efforts to build resilience not only in data center operations, but also within local communities and the natural environment.

"I'm proud of what our team has achieved over the last year, helping CyrusOne to meet far-reaching sustainability goals in addition to keeping pace with customer priorities, technological innovations, and government standards," said Eric Schwartz, Chief Executive Officer of CyrusOne. "These achievements demonstrate our commitment to customers and regulators and have real benefits to our business and being a part of a more sustainable future."

2022 was a year of key milestones for CyrusOne's sustainability programs with important achievements in each of its "Big Four" environmental categories: climate, water, biodiversity, and circularity.

Highlights of the CyrusOne 2023 Sustainability Report include:

• Climate: In 2022, CyrusOne accelerated its climate neutral by 2030 target and received validation from the Science Based Targets initiative (SBTi) for its near-term target.
• Water: CyrusOne achieved net positive water status for all data centers in regions with extremely high water stress. CyrusOne's net positive water colocation services in Dallas were also recognized by the Business Intelligence Group as a "Sustainability Service of the Year."
• Biodiversity: In 2022, CyrusOne's data center in Allen, Texas received the company's first National Wildlife Federation habitat certification.
• Circularity: Throughout the year, CyrusOne implemented on-site, customer E-waste recycling services at all the U.S. facilities that they operate.
• Benefits of Sustainability: The report illustrates how ESG initiatives support CyrusOne's business by improving resilience and increasing customer satisfaction.

The CyrusOne 2023 Sustainability Report provides disclosures compatible with four third-party standards, adhering to The Taskforce for Climate-related Financial Disclosures (TCFD) recommendations, the Global Reporting Initiative (GRI) standards, the Sustainability Accounting Standards Board (SASB) guidance, and demonstrating alignment with the UN Sustainable Development Goals (UN SDGs).
