Promotional Structure

NSSOL has established a Sustainability Committee, chaired by the Representative Director & President, to promote efforts to address sustainability issues. The Environmental Management Committee, chaired by the director in charge, has been established under the Sustainability Committee to analyze the business risks and opportunities associated with climate change and deliberate on measures to address them, manage targets and results of environmental impact indicators, and promote initiatives to reduce environmental impact. The committee is responsible for the promotion of activities, etc.

Promotional Structure

Information disclosure recommended by TCFD

Task Force on Climate-Related Financial Disclosures (TCFD) was created by the Financial Stability Board at a request of G20 to mitigate the risk of instability in financial markets caused by climate change. In June 2017, TCFD issued recommendations for companies to understand and disclose risks and opportunities presented by climate change. We announced our support to the TCFD recommendations in April 2022.


We have established “Sustainability Committee” chaired by the Representative Director & President as a system to promote our initiatives to deal with sustainability issues. We position the reduction of environmental burden including actions to deal with climate change issues as one of “materiality” and established the “Environmental Management Committee” chaired by the officer in charge under the aforementioned Committee through which we take actions including analyzing business risks and opportunities presented by climate change and reviewing actions taken, managing target index and actual performance related to environmental burden, and promoting activities to our reduce environmental burden. When we carry out our activities, we implement PDCA management under the environmental management system we created based on ISO 14001 standards. The Sustainability Committee receives reports from the Environmental Management Committee and reviews the policy on the actions on climate change issues and other sustainability issues and the status of progress of actions taken. Important issues are reported to the Executive Committee and Board of Directors.


We analyzed both below 2°C scenario and 4°C scenario up to 2050. As a result, the following risks and opportunities were identified.
Under below 2°C scenario, there is a risk of electricity cost increase due to strengthened legal requirements and social demands for CO2 reduction as well as reputation risk due to delay in taking actions, while DX needs such as saving and optimizing energy can be seized as a business opportunity.

below 2°C

4°C scenario, serious impact on business activities such as suspension of operation of DC and suspension of office functions due to delay in taking measures against more violent abnormal weather is feared. However, improvement of business continuity and sales opportunities will be ensured by attaining actions on climate change.


Note DC: Data Center

Impact = “Probability of impact” x “Severity”

  • Probability of impact
    3: Highly probable (90% or more); 2: Probable (50-90%); Less probable (10-50%); 0: Not probable
  • Severity of impact
    3: Extremely severe (significant impact on the revenue of the entire company); 2: Severe (impact on the entire business = impact on two operations (work and services)); 1: Minor (impact on main business = one operation); 0: Almost no impact


  • Now: Occurs now
  • Short-term: Will occur by 2025
  • Medium-term: Will occur by 2030
  • Long-term: Will occur by 2050

Risk Management

  • Actions against/for risks and opportunities from environmental perspective
    The Environmental Management Committee under the Sustainability Committee analyzes, throughout the entire company in a cross-sectional manner, risks and opportunities related to environmental issues including issues concerning climate change, reviews actions to be taken, and reports the results to the Sustainability Committee, and for important issues, to the Executive Committee and the Board of Directors.
  • Dealing with risks and opportunities through autonomous internal control system of the NSSOL Group
    The NSSOL Group has created and continues to improve internal control systems based on the autonomous internal control.
    Each section conducts risk management including understanding, assessing, and controlling business risks including climate change issues, and functional sections monitor the status of implementation and compliance.
    The status of activities of each section and functional sections is understood and assessed by the Internal Control and Audit Department through internal audits. The status of monitoring and internal audit by functional sections, including actions taken for environmental risks and opportunities mentioned in 1, is reported to the Internal Control Committee. Of these matters, important issues are reported to the Executive Committee and Board of Directors.

Specific actions

Reduction of power consumption

In the wake of the power crisis triggered by the Great East Japan Earthquake in 2011, we reviewed the way our company consumed power, and the company and employees have since been working together to reduce power consumption. As a result, we successfully reduced power consumption by 32.3% in 9 years.

Action by each employee

We encourage our employees to switch off lights in the workplace during lunch time, switch off computers when they leave the company, switch off lights in any unused places, set the temperature on heating and cooling systems to a proper degree, separate and reduce waste, and enhance the efficiency of their work.

Actions by the entire office

We are contributing greatly to the reduction of power consumption by, among other things, reducing total working hours through work practice reforms, introducing “thin client”, introducing power-saving PCs, eliminating and consolidating servers or transferring them to the Data Center, and eliminating individual air conditioners.
We are also going paperless to reduce the consumption of paper products by installing monitors in meeting rooms and reducing cabinets.

Our engagement in the environment through business

NS Solutions promotes resource saving and energy saving in accordance with our environmental policy by making our clients’ business more efficient. Here are some examples.

Promotion of utilization of the Data Center

Our state-of-the-art energy-saving Data Center is designed to achieve advanced environmental performance, i.e., PUE 1.4* or lower. By suggesting our clients to use this Data Center, we help our clients to reduce power consumption and also help preserve the global environment.

*PUE (Power Usage Effectiveness)

The value obtained by dividing power consumption of the entire data center by power consumption of server and other IT equipment. The smaller the value, the higher the effectiveness. The former includes the power consumed by the server, storage devices, router, and other IT equipment as well as power consumed by air conditioners, electric equipment, lights, monitoring devices, and other devices and equipment.

Examples at our clients

Promotion of utilization of cloud services

We offer cloud services using our state-of-the-art Data Center. Our clients will be able to eliminate their own server by using our cloud services, which will directly lead to a reduction of consumption of power. We believe that our cloud services operated through our power-efficient Data Center will also help preserve the global environment.
