A Commitment to Sustainability At CyrusOne, we often tout the great efficiencies of Massively Modular© data centers. However, we also recognize that building and operating datacenters leads to a concentration of environmental impacts. Being a leader in this industry means embracing our responsibility for reducing those impacts.

We see our sustainability mission in three parts:

We build data centers that are compatible with a sustainable future. We can’t just build a data center to meet today’s challenges, we need to build it with the future in mind.

We are committed to conserving water and energy through the effective design, maintenance, and operation of our facilities. We can’t just trade water for energy and ignore its impact.

We aspire to be strategic partners for sustainability with our customers to move their sustainability goals forward. Our customers have some of the most ambitious sustainability goals of any industry, so the best thing we can do for the environment is to help them succeed.

Conserving Water and EnergyThe primary environmental impacts from the data center industry are associated with energy use and water consumption, so these are the focus of our efforts. We address the conservation of these precious resources through effective design, maintenance, and operation of our facilities.

Benefits of Colocation over Onsite Servers

There are benefits to energy and water efficiency by transitioning from many small on-site data centers to fewer advanced hyperscale data centers, such as CyrusOne’s Massively Modular® data centers. Combining the needs of lighting, cooling, and power conditioning allows for economies of scale and can reduce the electrical consumption needed to keep the servers running their best.

Zero Water Consumption CoolingAt CyrusOne, all of our newly-built data centers are designed with zero water consumption cooling. This means no water towers, no evaporative cooling, and very low water use. While small amounts of water are still used for humidification, facility maintenance, and domestic water, this is just a drop in the bucket compared to facilities that use water for cooling.

Energy Efficiency

In addition to the benefits of consolidating computing into data centers, CyrusOne’s Massively Modular® data center design includes many energy- and cost-saving features, such as high-efficiency Uninterruptible Power Supplies (UPSs) and Power Distribution Units (PDUs), and variable-speed fan drives. Our Building Management System, sensors, and flexible infrastructure allow precise delivery

of the right cooling at the right time to the right space. These features give our new facilities an impressive design efficiency of 1.39 PUE when operating at full utilization.

Strategic Partners for SustainabilityCyrusOne’s commitment to customer service and satisfaction extends to being a strategic partner for sustainability. Our customers have some of the most ambitious sustainability goals of any industry. If we can be an effective partner in meeting their goals, we can help move society forward towards a sustainable future.

Access to Renewable Power

Many companies have targets to increase their use of renewable power, and we are here to help. We have verified that all of our power providers can offer renewable energy certificates to pair with your server power demand to help you meet your targets. For companies that are looking for something more, please contact us and see how we can work with you toward your goals.

Recycling for You and Us

Many of our data centers offer meeting rooms for customer use and as part of our customer service, we offer office recycling at all locations. This matches the recycling we do behind the scenes with our electronics and equipment.

Transparency

To be a strategic partner, we need to provide good information for our customers’ decisions. This is why we provide sustainability data for each of our facilities to help with reporting and site selection, with a focus on water risk and power grid composition.
