The data centres owned and operated by the NRI Group strive to achieve net-zero power consumption through a dual approach of transitioning to renewable energy sources and reducing overall power consumption.

As of the end of March 2023, all electricity consumed in these data centres is sourced exclusively from renewable energy.
In addition, the NRI Group regularly convenes the Data Centre CO2 Reduction Promotion Meeting to advance initiatives aimed at reducing energy consumption and upgrading systems. These meetings focus on optimizing power usage and exploring options, such as solar panel installations.

The Group has consistently prioritized enhancing the environmental performance of its data centres. For instance, at Tokyo Data Center 1, which has been operational since November 2012, several energy-saving facilities have been implemented. These include a "double-deck system," which separates the server equipment floor from the air conditioning and facility-related equipment floor, enabling more efficient and flexible air conditioning. Additionally, a "cold-water vertical heat storage tank" has been installed to enhance cooling efficiency further.

Migrating systems to these energy-efficient data centres has contributed to a 26.2% reduction in the Group's GHG emissions between FY 2016 and FY 2022. Moving forward, the Group remains committed to adopting designs and technologies that drive further energy savings.
