Fostering 'Love of the Earth' and Realizing a Sustainable Society through Protective and Proactive Sustainability Start of joint research based on a shared vision between[...]

Tokyo - June 5, 2024 - NTT Corporation (hereinafter "NTT") and Waseda University (hereinafter "Waseda") have begun joint research with a shared vision that aims to create new values in the fields of the global environment, energy, food, sports, and health to foster a "Love of the Earth" and realize a sustainable society.
This joint research will be conducted on four research themes, starting with "protective sustainability" and "proactive sustainability". The two organizations will promote a system that integrates the humanities and sciences, transcending the boundaries of each specialized field, which has not yet been achieved through their previous joint research.

1. Background

In recent years, there has been an urgent need to solve global issues related to the survival of humanity, such as global warming and energy, environmental, and food crises. In addition, internet traffic has increased by approximately 90 times, and power consumption has increased by more than 5 times in 20 years due to the widespread use of smartphones, AI, IoT, etc. As a result, network delays, congestion, energy depletion, and greenhouse gas emissions have worsened. To solve these issues, it is necessary to promote two energy conservation efforts: "protective sustainability", which is an effort to prevent the current situation from deteriorating through energy conservation and environmental preservation, and "proactive sustainability", which is a proposal for drastic solutions through new ways of energy creation and food supply methods.
NTT and Waseda University have launched this research with the intent to leverage their strengths and contribute to creating new values and realizing a sustainable society (Figure 1).

2. Significance of this joint research system

Waseda University boasts strong research capabilities, not only in the fields of science and engineering represented by emerging technologies such as nano-energy, ICT, and robotics, but also in the humanities and social sciences such as politics, economics, law, business administration, literature, and linguistics.
In preparation for the 150th anniversary of the University, Waseda will establish 3 global centers to promote the convergence of knowledge that contributes to society in order to realize a Waseda that shines on the global stage. In 2024, the University established the Global Research Center (GRC), which will serve as the research command center, to develop, advance, and integrate original research that can bring change to our society. Under the leadership of the president and provost, Waseda will be a research university that contributes to the world by working towards solving the world's most pressing issues. This program will strengthen the University's top-down research capabilities along with the creation of original and innovative research foundations from the bottom-up.
Under the IOWN concept1, NTT is researching and developing a next-generation communication infrastructure that utilizes cutting-edge optical and information processing technologies to create a smart world. With IOWN's low power consumption, high capacity, high quality, and low latency network, NTT aims to create new values and realize a global sustainable society.
Although Waseda and NTT have conducted a number of joint research projects in the past, it has been common practice to conduct joint research limited to labs related to each subject, and the system was not designed to involve multiple organizations or researchers. To solve today's complex social issues, the two organizations have introduced this shared vision approach because they believe it is necessary to share a common vision, build a research system that works across multiple organizations and between multiple researchers, and bring various skills and ideas to the table.
In addition, it is not enough to create technologies through research. It is also important to propose how to deploy the technology and how to build business models to implement it into the existing systems.
Therefore, within the framework of this joint research, NTT and Waseda will focus on the integration of the humanities and science across multiple research institutions.
Through this collaboration between Waseda and NTT, the organizations will create new technologies that can contribute to the future of humanity.

3. Overview of joint research

(1) Create a joint research vision and determine research topics

At the start of the joint research, NTT and Waseda decided on a vision, "Love of the Earth"based on the joint research theme that combines the fields of the global environment, energy, food, sports, and health with IOWN, NTT's R&D program, based on "protective sustainability" and "proactive sustainability" (Figure 2).

Figure 2 Joint Research Vision

39 researchers from Waseda and NTT from various fields and careers came together and decided on research topics that were in line with the shared vision (Figure 3).

<4 research themes>

  • A world that values people, society, and the earth
  • A world free from international conflicts and wars
  • A world of sports and health that is full of fun and enriches the mind
  • A world where the joy of eating leads to global happiness

4. Outlook

This joint research will be carried out over the span of three years. In the first year, the research content will be concretized and examined. In the second year, the technology will be verified, and in the third year, the demonstration of the social implementation will be carried out. In addition, the results obtained through joint research are not limited to research, the organizations will also promote social implementation led by the NTT Group.
Waseda and NTT aim to contribute to society through the co-creation of a sustainable society with the vision of fostering "Love of the Earth" and new values that inspire people in the fields of global environment, energy, food, and sports based on "protective sustainability" and "proactive sustainability".
