We, at the Komatsu Group clearly defines the basic policies of environmental conservation, which will be the guidelines of business activities, when engaging in business activities while working to realize a sustainable society, and promotes environmental conservation activities.
Komatsu Earth and Environment Policy (September 2026 revision)
Humankind must not only promote the further development of a prosperous and comfortable society but also pass down our planet earth and its indispensable environment to future generations in a sound and healthy condition.
Based on the Komatsu Sustainability Policy, we have established this Earth and Environment Policy to address issues important to both a sustainable society and our business and to grow as a corporate group capable of responding flexibly to changes in society and the external environment. 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. We promote initiatives to address global environmental issues, including carbon neutrality, resource circulation, and achieving nature positive outcomes, and contribute to the development of a sustainable society.
As a group of companies working to improve our manufacturing for the satisfaction of our customers, we at the Komatsu Group are committed to improving both our environmental performance and economic efficiency. To this end, we are constantly engaged in technology innovation to provide economical products, services and solutions through improving energy efficiency at our customers’ workplaces and strengthening their cyclical businesses, while striving to minimize the environmental impacts related to the entire lifecycle of products from production to disposal.
We at the Komatsu Group promote environmental conservation by ensuring full compliance with environmental laws and regulations relevant to our business and by establishing our own voluntary standards addressing global and local environmental concerns. We also recognize the impacts of our business activities on biodiversity and strive to conserve and restore biodiversity. Each company of the Group also strives to fulfill our collective corporate social responsibility and create value toward a sustainable planet and future through participating in environmental conservation activities in each region, disclosing environment-related information to society, and maintaining close communications with our stakeholders and reflecting their feedback in our activities.
We at the Komatsu Group contribute to sustainable development and climate change mitigation and adaptation, as well as biodiversity conservation and restoration, through the following initiatives.
In line with international goals and standards relevant to Komatsu’s business, including the Paris Agreement, we will reduce the amount of energy used and greenhouse gas emissions generated across our business activities and the entire product lifecycle. We do not limit ourselves to cutting emissions from our bases and from the use of our products. Rather, we broaden the target to include customer workplaces in their entirety through the optimization of onsite operations.
Through our business processes, we work to minimize the use of natural resources such as materials and water, promote their reuse, or recycle them as much as possible. At the same time, we ensure the comprehensive reduction of waste in all business areas. In addition, we promote resource recovery and the effective use of by-products and waste throughout the value chain. We also contribute to building a circular society through our forestry machinery business, which supports circular forestry encompassing planting, forest cultivation and harvesting, as well as our remanufacturing (Reman) operations, which involve the refurbishment and reuse of components.
We comply with local laws and regulations concerning the conservation of water quality and the prevention of air pollution, noise and vibrations, and manage these matters based on our own established standards.
As much as possible, we also ensure the comprehensive management of chemical substances used in our business activities, while continuously working to reduce the use of chemical substances of concern or replace them with alternatives for the discontinuation of their use.
In line with international goals and frameworks, including the Convention on Biological Diversity and the Kunming-Montreal Global Biodiversity Framework, we give due consideration to areas of biodiversity importance* and their surrounding areas. Across Komatsu’s operations and the value chain, we identify, analyze and assess nature-related dependencies, impacts, risks and opportunities, and prioritize initiatives according to their significance.
Regarding our forest conservation efforts, we comply with applicable laws and regulations in each country, including those aimed at preventing illegal logging, and contribute to appropriate forest management through our forestry machinery business, thereby helping prevent biodiversity loss.
Furthermore, through “one-site, one-theme” biodiversity activities tailored to local characteristics at each Group site and through social contribution activities, we promote employee participation in biodiversity conservation and restoration.
We, together with major companies of the Komatsu Group, will establish an Environmental Management System, and will apply the PDCA cycle to work to maintain and improve environmental activities. Other group companies and suppliers will also work to establish environmental management systems that help to maintain and improve environmental activities.
Each company or business unit of the Komatsu Group will set its own mid- and long-term targets in accordance with the mid- and long-term targets set based on the Komatsu Strategic Growth Plan, and will develop and implement specific activity plans. Top management will regularly review targets, activity plans and status, and work on continuous improvement.
We at the Komatsu Group believe that it is important to enhance the environmental awareness of each employee. To this end, we will actively promote environmental awareness and education programs among all employees.
We will seek to ensure that all employees recognize the importance of addressing climate change, establishing a circular society, and conserving and restoring biodiversity, and participate in these activities.
We will gather environment-related information from each company or business unit of the Komatsu Group, and strive to disclose information concerning all business activities. We will also facilitate proactive dialogue and collaboration with all our stakeholders, including suppliers, sales and service distributors, and business partners, and strive to build relationships of trust.
* Areas of biodiversity importance:
・Habitats of threatened species classified as Critically Endangered, Endangered, or Vulnerable on the IUCN Red List of Threatened Species, which assesses extinction risk worldwide, and habitats of species endemic to a specific country or region
・ Internationally recognized areas, such as UNESCO World Heritage sites and Ramsar Sites (Wetlands of International Importance)

Among our important business challenges, the Komatsu Group includes climate change in the objectives of our business strategies.
