Komatsu Earth and Environment Policy (June 2022 revision)
Corporate Principles
1. Contributions to Realization of a Sustainable Society
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.
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 also aim to achieve carbon neutrality with net zero CO2 emissions by 2050, and contribute to sustainable development through efforts to reduce CO2 emissions from products and in our manufacturing, and to establish a recycling-oriented society.
2. Simultaneous Realization of Environmental and Economic Performance
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 fuel 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.
3. Observance of Corporate Social Responsibility
We at the Komatsu Group promote environmental conservation by not only complying with the applicable laws and regulations of our host communities, regions and countries but also by establishing our own voluntary standards addressing global and local environmental concerns. 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.
Guidelines for Corporate Activity
1. Initiatives for the Earth and Environment
We at the Komatsu Group contribute to sustainable development and climate change mitigation and adaptation through the following initiatives.
1)Response to Climate Change
We will reduce the amount of energy used and greenhouse gas emissions generated across the entire lifecycle of our business. 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.
2)Establishment of a Recycling-oriented Society
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. We also contribute to the establishment of a recycling-oriented society by strengthening our forestry machinery business, which supports a sustainable forest management cycle of planting, cultivating and harvesting, as well as our remanufacturing (Reman) operations, which involve the refurbishment and reuse of components.
3)Conservation of Air, Water and Other Natural Systems as well as Management of Chemical Substances
We comply with not only local laws and regulations but also with our own established standards concerning the conservation of water quality and the prevention of air pollution, noise and vibrations.
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 potentially harmful chemical substances or replace them with alternatives for the discontinuation of their use.
4)Response to Biodiversity
We recognize biodiversity as an important environmental issue, evaluate, understand and analyze impacts on it in all our business areas, and work on our tasks according to the criteria of highest impact and/or most effective actions.
2. Framework of Global, Group-wide Environmental Management System
Komatsu and major companies of the Komatsu Group will establish an Environmental Management System, and will 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 mid-term management plan, and will develop and implement specific activity plans. Top management will regularly review targets, activity plans and status, and work on continuous improvement.
3. Environmental Education and Communication
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 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 dialogues with all our stakeholders, such as customers, employees, local communities and suppliers, thereby further improving the content of our environmental communication.
