Building data centers for a more sustainable tomorrow

Sustainability is important not just for the planet, but also for business. As one of the largest global data center providers, we feel a real sense of urgency to take our impact seriously. As this is a real responsibility, we've signed up to a number of goals and initiatives to ensure driving necessary change is at the top of our agenda. The highest profile of these has been becoming a Business Avenger for the UN Sustainable Development Goal 11: Sustainable Cities and Communities. This makes our commitment clear, as we proactively and urgently look for ways to reduce our environmental impact.

For more than 20 years, our global data center teams have been a driving force of sustainable change, collaborating and exploring advances across energy supply and consumption and data center building design. Around the world, our data center teams take measures to develop innovative solutions and have options for renewable energy sources that will enable more sustainable practices across our own and client-operated sites. There’s especially potential to improve IT load efficiencies within a data center and ensure equipment is working smarter, not harder, fitted with the latest technology to perform more efficiently per wattage.

New NTT data centers are designed with a sustainable digital world in mind

Power usage effectiveness (PUE) is a measure of the power efficiency of a data center and our new data centers are designed to meet the lowest PUE possible, and industry best practice across our different locations. For example, our new London Data Center has a central cooling system engineered to not use any refrigerants that contribute to dangerous greenhouse gases. These components have significant global warming potential, so leaving them out of our cooling systems creates a more sustainable environment for our clients and their customers. This delivers a designed PUE of 1.2. All power to our London data centers is from 100% renewable energy sources, including onshore and offshore wind sites.
In the United States, we also partner with local utility providers to offer renewable energy options at all of our US data center campuses. For example, our three data centers in Sacramento, California
