―Achieving carbon neutrality―
In September 2021, the NTT Group unveiled its new environment and energy vision, "NTT Green Innovation toward 2040" for achieving "zero environmental impact" while continuing "economic growth" by reducing the environmental impact of its business activities and creating breakthrough innovation, with the aim of creating a well-being society and boosting corporate value through ESG initiatives. NTT will aim to achieve carbon neutrality by fiscal 2040 based on this vision.
NTT has set targets for groupwide carbon neutrality by fiscal 2040 on its way to achieving zero environmental impact. The mobility communications (NTT DOCOMO) and data center business will be the first within the NTT Group to achieve carbon neutrality, as targets have been set to reduce greenhouse gas emissions by 80% of fiscal 2013 levels, by the fiscal year ending March 31, 2031. This target was approved as the 1.5°C level by SBT in December 2021.
Scope of reduction targets GHG protocol: Scope 1 (own direct emissions of GHG) and Scope 2 (indirect emissions from using electricity, heat and steam supplied by other companies) Mobile: 15 companies in NTT DOCOMO Group (as of September 28, 2021)
With the current situation, data traffic will increase significantly, leading to an increase in energy consumption and thus greater greenhouse gas emissions. In order to achieve carbon neutrality, IOWN will be rolled out to reduce energy consumption, increase the use of renewable energy sources, and cut down on greenhouse gas emissions.
Of the total power consumption during fiscal 2021, switching to renewable energy sources for more than 1.8 billion kWh (approx. 23% of power consumption, approx. 150% compared year-on-year) used by the entire Group resulted in greenhouse gas emissions of 2.90 million tons, a reduction. of 38% compared to FY2013 levels.
In July 2022, NTT FACILITIES' power engineering and other power-related operations, primarily design and maintenance of solar power plants and power supply facilities for telecommunications, were transferred and integrated into NTT ANODE ENERGY. Through this integration of power-related operations, NTT Anode Energy will promote four businesses: the green power generation business, regional grid business, consumer energy business, and construction and maintenance operations business. By linking these four businesses into a single integrated value chain, the company will develop a smart energy business.
Overview of NTT Anode Energy's Post-integration Smart Energy Business
・ Green Power Generation Business: Development of renewable energy power plants
・ Regional Grid Business: Promote expansion of the use of NTT Group's assets to enhance local production and consumption of renewable energy and resilience
・ Customer Energy Business: Promote carbon neutrality among customers by offering decarbonization solutions
・ Construction/Maintenance Operations Business: Aim to improve quality and efficiency by enhancing power engineering functions (construction, maintenance, and monitoring)
To achieve carbon neutrality, a resolution was passed at the Executive Committee meeting in May 2022 to gradually implement an "Internal Carbon Pricing System" within Group companies. This system encourages reducing our impact on the environment by virtually converting CO2 emissions into costs.
Overview of Internal Carbon Pricing System implemented by the NTT Group
A service lineup that began supplying "docomo Denki™" from March 2022 as a distributor harnessing its partnership with NTT Anode Energy. One of the plans, "docomo Denki Green," makes full use of renewable energy sources* for its supply, helping to achieve carbon neutrality throughout society as a whole.
* Renewable energy sources include the use of specified non-fossil fuel certificates.
NTT Communications is the first in Japan to offer*1 a renewable energy menu that enables customers (subscribers who use cages or rooms) to select the electricity used by their ICT equipment*2 for largescale commercial data centers utilizing renewable energy supplied by NTT Anode Energy. In addition, information on the power plant and the amount of electricity used will be provided on an individual basis as a type of "environmental value" utilizing non-fossil certificates*3.
