Feature 1: Environment and Energy Vision

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 Green Innovation toward 2040" targets

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)

Basic Policy and Action Guidelines

Basic Policy

The NTT Group is committed to achieving a new level of prosperity where humanity can coexist and preserve nature for generations to come. To this end, we will work to balance solving ecological problems and improving economic development by reducing the environmental impact of our business activities and creating new technologies and innovations.

Action Guidelines

1. Reducing greenhouse gas emissions

The NTT Group is committed to initiatives that reduce greenhouse gas emissions throughout its business activities and society as a whole, by rolling out IOWN technology, increasing development and use of renewable energy sources, and providing services that contribute to carbon neutrality.

2. A commitment to resource recycling

We will shift from a one-time use consumption-oriented company to a recycling-oriented one.
We will promote the effective use of resources throughout the entire life cycle of products and systems, from procurement to use and disposal.

3. Conserving ecosystems

Through our business and employee activities, we will promote initiatives related to conserving ecosystems within nature.

4. Compliance with laws and regulations and fulfillment of social responsibilities

We comply with the laws and regulations related to environmental issues in each country andregion, and act with high ethical standards.

5. Establishing and maintaining environmental management systems

We will establish the Green Innovation Committee chaired by the Representative Director and Senior Executive Vice President, and discuss basic strategies concerning environmental issues, the status of implementation of activities, and information disclosure, and implement relevant initiatives.

6. Stakeholder engagement

We will engage with stakeholders throughout our entire value chain to help resolve environmental issues.

NTT Group's Environmental Activities

The NTT Group established the NTT Group Global Environmental Charter in 1991 based on the NTT Group CSR Charter, which lays out the basic policy for CSR activities. The NTT Group Global Environmental Charter outlines the basic principles and policies for conservation of the global environment, and was used as the basis for formulating the "The NTT Group Environmental Statement," "The Eco Strategy 2030" and the "Environment and Energy Vision" that NTT Group as a whole has adopted for its environmental activities.

Key Initiatives Toward Carbon Neutrality

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.

Illustration of NTT Group Greenhouse Gas Emission*1 Reductions

  1. GHG Protocol: for Scope 1 and 2
  2. Estimated Introduction of Renewable Energy (including actual renewable energy through Non-Fossil Fuel Certificates)
    → FY2020, 1.0 billion kWh; FY2030 to FY2040, around 7.0 billion kWh. The introduction of renewable energy will have the optimal types of energy determined on the basis of each country's energy composition, etc.
    Approximately half of the domestic renewable energy usage is anticipated to be from energy sources owned by NTT (FY2030).
  3. Estimated Reduction of Energy Consumption through the Introduction of IOWN (Comparison to Outcome).
    → FY2030, (2.0) billion kWh ((15)%); FY2040, (7.0) billion kWh ((45)%) Percentage of Introduction of IOWN (Photonics-electronics Convergence Technologies, etc.) out of Total Energy Volume
    → FY2030, 15%; FY2040, 45%

Initiatives for the reduction of society's environmental impact

The concept of "Self as We," where people will seek to increase their happiness along with the happiness of others, forms the basis of NTT Group's initiatives for achieving a sustainable society, while every effort is being made toward "Green by ICT" to help reduce the environmental impact of society as a whole. Due to the very nature of the NTT Group's businesses, greenhouse gas emissions arising from the supply chain (Scope 3) are much higher than direct emissions from the group's own activities (Scope 1+2), and measures will be implemented to reduce such emissions from across the entire supply chain.

Contributing to the reduction of society's environmental impact, together with reductions throughout the NTT Group

  1. Conditions for reduction estimates
    • Target: beginning in FY2040
    • Adoption rate of IOWN for electric semiconductors, etc. (Photonics-electronics convergence technologies, etc.): approximately 50%
    • CO2 Emission factor: Japan, 0.185kg-CO2/kWh; World, 0.130kg-CO2/kWh
  2. CO2 Reduction potential: approximately 50% (2030; Target, World; calculated based on GeSI and IEA estimates)

Specific Initiatives

In addition to the "Green of ICT," which will curb the environmental impact of NTT Group by introducing IOWN technologies and increasing the use of renewable energy, we will also work on "Green by ICT, " which will contribute to reducing the environmental impact of society as a whole.

Toward Introduction of Internal Carbon Pricing System

The NTT Group will introduce an Internal Carbon Pricing System from FY2022, as it is planning to revise its procurement system that factors in carbon pricing.
NTT believes that this framework will be essential for lowering risks related to a decarbonized society and for promoting decarbonization.
