Environment and Energy Vision

We have formulated the Environment and Energy Vision in May 2020 and have declared to increase the proportion of renewable energy use by the NTT Group as a whole by 30% or more by FY 2031.

In September 2021, we have also formulated a new environment and energy vision "NTT Green Innovation toward 2040" to simultaneously achieve zero environmental impact and economic growth by "Reduction of Environmental Impact through Business Activities" and "Creation of Breakthrough Innovation". Based on this vision, our group aims to be carbon-neutral by FY 2040.

In November 2021, the NTT Group restructured its existing CSR Charter, which lays out the basic policy for CSR activities including environmental activities, and established the NTT Group Global Sustainability Charter. Based on this charter, the NTT Group will promote various initiatives to support our commitment towards a sustainable society. The IOWN concept will support these initiatives enabled by high ethical standards and cutting-edge technologies and innovation. The NTT Group will promote corporate and economic growth and, at the same time, will contribute to resolving social issues to realize a sustainable society.

Goals under the "NTT Green Innovation toward 2040"

The NTT Group has set the following goals for FY 2030 and FY 2040.

Fiscal year Main targets
2030 80% reduction of greenhouse gas emissions from FY 2013 for NTT Group
Carbon neutrality for mobile (NTT DOCOMO) and data centers sectors
2040 Carbon neutrality for NTT Group

(Targets of the above reduction objectives)

GHG protocol: Scope 1 (our own direct greenhouse gas emissions) and Scope 2 (indirect emissions associated with the purchase of electricity, heat and steam that are provided by other companies)
Mobile :15 companies in the NTT DOCOMO Group (as of September 28, 2021)

Main activities for achieving carbon neutrality by 2040

NTT Group will achieve carbon neutrality through a combination of
(1) Increased use of renewable energy: Reduce greenhouse gas emissions by 45 %
(2) Lower energy consumption with IOWN technologies: Reduce greenhouse gas emission by 45 %

*1.Science Based Targets : Scientifically based greenhouse gas emission reduction targets for corporates in accordance with the Paris Agreement. The SBT initiative, a climate change initiative led by the United Nations Global Compact (UNGC), the CDP (formerly the Carbon Disclosure Project), the World Resources Institute (WRI), and the World Wide Fund for Nature (WWF), designates the targets.

*2.Scope 1 : Direct emissions of greenhouse gases by businesses, such as fuel combustion
Scope 2 : Indirect emissions from the use of electricity, heat and steam supplied by other companies

*3.Scope 3 : Indirect emissions other than Scope 1 and Scope 2 (Emissions in the supply chain related to business activities)

Participation in EP100*4 and EV100*5

NTT Group has participated in the EP100 and EV100 international initiatives for energy efficiency sponsored by The Climate Group.
