External Evaluations and Commendations


Received the Yokohama Global Warming Countermeasures Award on April 23, 2018

NTT Communications Corporation has received the Yokohama Global Warming Countermeasures Award from the City of Yokohama.

The award, from the City of Yokohama Global Warning Countermeasures Plan Program, is given to companies that have achieved outstanding results, such as a substantial reduction in greenhouse gas emissions. In fiscal 2017, 19 companies were selected from 308 that had submitted reports to the city. NTT Communications was recognized for achieving an 8.4% year-on-year reduction in CO2 emissions in fiscal 2015 at the Yokohama West Building and Yokohama Yamashita Building. 

Specifically, the company improved power supply efficiency by consolidating its data communications system to reduce electricity consumed and by replacing older rectifiers with a low utilization rate to high-efficiency units and consolidating the overall rectifier system.

Looking ahead, we will further strive to preserve the global environment by focusing on saving energy and reducing greenhouse gas emissions.

NTT Communications Receives the Special Excellent Enterprise Award under the Enterprise Emission Reduction Planning Program from Kyoto City (December 22, 2017)

This award recognizes the efforts of certain business enterprises to cutback greenhouse gas (GHG) emissions. In this instance, and selecting from a total of 141 companies, 37 business enterprises were assigned the highest possible “S” rating for their endeavors. Of these 37 business enterprises, seven were further recognized with Special Excellent Enterprise awards. In specific terms, NTT Communications achieved a CO2 emission reduction rate of 28.2% compared with the average rate for the base period from fiscal 2010 to fiscal 2013 at its Kyoto Minami Building . This reduction was largely attributable to air flow improvements (the installation of diffusers (wind direction plates) and screens as well as the optimal use of floor panels), coupled with energy conservation measures including increased flexibility in the setting of machine room temperatures. Moreover, this award reflects the high esteem in which the Company’s proactive efforts to protect the environment are held. These efforts are based on the Group’s Environment Vision and targets. Looking ahead, NTT Communications will continue to promote energy conservation measures and work diligently to reduce GHG emissions.

Ranked second in the 21st Nikkei Environmental Management Survey (communication and services section) conducted by Nikkei Inc. (January 22, 2018)

NTT Communications Corporation ranked second in the non-manufacturing sector (communication and services section) in the 21st Nikkei Environmental Management Survey conducted by Nikkei Inc. The company earned a high score in all four survey categories and was at the top of the “Pollution- and Biodiversity-related Measures” category. 

Started in 1997 by Nikkei Inc., the Environmental Management Survey annually assesses business endeavors to improve environmental measures and management efficiency.

Companies surveyed in the communication and services section are assessed and scored on the basis of their initiatives and achievements in four criteria: (1) environmental management promotion structure, (2) pollution- and biodiversity-related measures, (3) resource recycling, and (4) global warming countermeasures. Next they are ranked by total score (maximum score of 400 based on a perfect score of 100 for each of the four criteria).

In this year’s survey, we received high scores for efforts such as linking key CSR activity items to SDGs, setting a CO<sub>2</sub> emissions reduction target for fiscal 2030, an initiative to reduce electric consumption, tracking energy consumption in overseas operations, and introducing natural refrigerant in place of HCFC and a fresh air air-conditioning system, not to mention projects for preserving forests and protecting animals and plants. As a result, the company ranked second with a total score of 386 out of 400.

In November 2016, we set the medium and long-term environmental goals including the NTT Communications Group Environmental Statement and Eco Strategy 2030.

Toward a future in which people live in harmony with the Earth, we will work on globally enhancing environmental management to realize three aspects of the future: realizing a low-carbon future, implementing closed-loop recycling, and planning a future of natural harmony, by providing innovative technologies and services.
