Note: The ubiquitization of telecommuting, expansion of digitalized business forms and other facts since FY2020 have advanced the shift to paperless operations.
Water usage
Data centers operated by the CTC Group are using water to cool their IT equipment. Those centers are working to reduce the volume of water they use through measures such as the introduction of rainwater recycling facilities and high-efficiency heat source equipment, as well as through the practical use of district heating and cooling systems and well water.
