Organization to Promote CSR

System for promoting environmental and social (CSR) activities

Our system to promote CSR

The CSR Department is an organization under the direct control of the President and has established the CSR Committee chaired by the President, and has the opportunity for top management to regularly discuss the direction of CSR strategy. In addition, the CSR Steering Committee, which consists mainly of related officers, conducts discussions on the policy of individual activities, and in particular, is responsible for governance functions in conducting social contribution activities.

Our CSR activities are integrated to our daily business activities, and we engage in them through dedicated divisions and committees organized in all our Group companies. With respect to our major overseas subsidiaries, we communicate with staff responsible for CSR activities on a daily basis and share information in an effort to bolster our organization and promote CSR activities worldwide.

Reinforcement of Our CSR Systems

Evaluation Tools for CSR Activities

We evaluate new initiatives to determine whether they are beneficial to both our business and our stakeholders. Of particular importance are social contribution activities (donations), which we have monitored diligently with regards to their effectiveness as CSR activities since FY2013. This is carried out using a donation check sheet that we created to assess quantitative effects via two perspectives (our business and our stakeholders), which is then evaluated by our CSR Steering Committee upon completion.

Global Information Sharing

Prior to FY 2015, information on CSR activities implemented in overseas subsidiaries were obtained through questionnaires that were collected periodically. We have since updated this system in order to increase its reach and effectiveness; the information is now updated daily on a bulletin board so that it can be disseminated on a global scale through the intranet.

In addition, overseas subsidiaries set up places for exchange of opinions through individual visits, e-mail, telephone, etc., for about 30 persons in charge who are responsible for the CSR activities of each company to share current status globally. In the future, by collecting various opinions from various areas of the world, we will create a system to comprehensively understand and share what is required on the front lines of the business sites.

Corporate Principles

1. Contributions to Realization of Sustainable Society

Mankind must not only promote the further growth of a rich and comfortable society but also pass down this indispensable environment of our planet earth to future generations in a sound and healthy condition.
We, at the Komatsu Group, define environmental conservation efforts as one of the highest priority management tasks, and endeavor to contribute to the sustainable growth of society by integrating advanced technologies into environmental conservation efforts in all our business activities. This is represented by our hybrid construction equipment which features a substantial reduction of CO2 emissions while in operation and by our superior manufacturing.

2. Simultaneous Realization of Environmental and Economic Performance

We are committed to improving both environmental performance and economic efficiency, as a group of companies working toward superior manufacturing for customer satisfaction. To this end, we constantly take up the challenge of advancing technologies to develop creative products that improve both environmental performance throughout the product's life cycle and the product's economic performance at the same time.

3. Observance of Corporate Social Responsibility

Each company of the Komatsu Group promotes environmental conservation by not only complying with the applicable laws and regulations of the concerned host community, region and country but also by establishing its voluntary standards which consider global and local environmental concerns. Each company of the Group also strives to fulfill its corporate social responsibility by actively participating in local environmental conservation programs and thereby promoting close-knit communication with local communities, while striving to become a company trusted by all Komatsu stakeholders.

Guidelines for Corporate Activity

1. Basic Stances on Earth Environmental Problems

We, at the Komatsu Group, work for sustainable society and earth environment through our global business operations by addressing the following four environmental problems with the stances discussed below.

1)Climate Change

We will reduce the use of energy and emissions of greenhouse gas in all phases of our business activities ranging from research and development, procurement, production and logistics to sales and service as well as in the total life cycle of our products and services.

2)Establishment of a Sound Material-Cycle Society

Through our business processes, we work to minimize the use of natural resources, such as materials and water, promote their re-use or recycle them as much as possible, and expand Zero Emissions from our manufacturing activities around the world. At the same time we ensure the thorough management of waste materials in all our business domains, including our suppliers and distributors.
We also continuously work to increase the recyclability rate of products at the time of disposal.

3)Conservation of Air, Water and Other Environments as well as Management of Chemical Substances

We comply with not only local laws and regulations but also with our established standards concerning the conservation of water quality, prevention of air pollution, noise and vibrations.
As much as possible, we also ensure the thorough management of chemical substances for use in our business activities, while continuously reducing the use of potentially harmful chemical substances or replacing them with alternative substances for discontinuation of their use.


We recognize biodiversity as one of the important issues concerning the earth environment, evaluate, understand and analyze impact on it in all our business domains, and work on our tasks according to the criteria of the highest impact and/or the most effective actions.

2. Framework of Global, Group-wide Environmental Management System

The Komatsu Head Office, as well as the manufacturing facilities and main companies of the Komatsu Group, already with ISO certifications, will work to maintain and improve their environmental management system, while other manufacturing facilities and suppliers will also work to establish their environmental management systems and reduce their environmental impact.
The Komatsu Environmental Committee develops environmental action plans and common guidelines for the Komatsu Group. Based on these Group-wide plans and guidelines, each division or company sets up its own mid- to long-term targets, develops and implements specific action plans, reviews them regularly and works to continuously improve them.

3. Environmental Education and Communication

We believe that it is important to enhance the environmental awareness of each and every employee and thereby actively promote environmental awareness and education programs for all employees.
We will gather environment-related information concerning not only our manufacturing facilities but also other related entities, such as major affiliated companies and suppliers, and strive to disclose such information, thereby facilitating proactive communication with all our stakeholders, such as customers, employees, local communities and suppliers and further expanding the content of environmental communication.

Setting Mid- and Long-Term Objectives and Progress

Setting Mid- and Long-Term Targets and Progress

Komatsu has been moving forward under the new mid-term management plan from 2019. We set new ESG targets and expressed our commitment to sustainable growth through a positive cycle of profit improvement through growth strategies and initiatives for ESG issues.
Our targets from fiscal 2019 are to reduce CO2 emissions from products and production by 50% by 2030. In addition, as a new indicator, we decided to aim for a ratio of 50% of renewable energy power (RE ratio) by 2030.
The new mid-term 2030 targets, including other indicators, are as follows:

DJSI World: Selected

SBT (Science-Based Targets) Approved

Komatsu's CO2reduction objectives have been certified by SBT as of April 11, 2017.
SBT (Science-Based Targets) is an initiative that involves “setting goals that are compatible with science.”
The COP21 (Paris Agreement) marked the introduction of a new set of CO2reduction objectives that were submitted by various countries. However, even with the summation of target values, it was found that it would be impossible for the increase of average global temperatures in 2100 to be stay within 2℃ (as compared to temperatures before the Industrial Revolution).
Therefore, after a detailed examination by the businesses of the world, reduction objectives have been reassessed and SBTi (SBT initiative: CDP, Global Compact, WRI, WWF) is supporting and approving SBTs to reach the goal of an increase of less than 2℃.
Komatsu 's SBT meets the requisites of the temperature increase of less than 2℃ scenario.

Komatsu 's SBT are as follows

  1. SCOPE1+2: Base unit -49% (Target Year 2030; Base Year 2010)
  2. SCOPE3: Total -46% (Target Year 2030; Base Year 2012)
  • Note: While Komatsu's 2015 medium and long-term objectives (2020 and 2030 respectively) differ from SBTi in terms of a few requisite conditions (such as using the same base year for assessing both domestic and overseas operations) and target values, the targeted rates of reduction are comparatively equal.
