Environmental Management

The Kubota Group has systematically established its environmental management systems in order to facilitate business operation throughout the entire value chain including business sites and operational divisions based on the Kubota Global Identity and the Environmental Charter. The Group also promotes environmental management that is appropriate for the type of business activities of the site/operational division. Production sites, in particular, are associated with large environmental loads related to energy and waste, as well as the risks of air pollution and water contamination. In order to properly address such risks, the Group has established environmental management systems based on ISO 14001 and EMAS, and is endeavoring to promote business management in accordance with the required rules and the continuous improvement of environmental conservation activities.

Compliance with Environmental Laws and Regulations

To ensure compliance with environmental laws and regulations and prevent environmental accidents, the Kubota Group conducts its business in accordance with the rules and regulations it has formulated in relation to environmental conservation.
For exhaust gas, wastewater, noise, vibration and other variables, the Group has set and thoroughly manages its own control values at each production site, which are stricter than the corresponding laws and regulations, and has also established a system to promptly report any instances of non-compliance or complaints relating to environmental laws and regulations to relevant government bodies and the head office.
Each year, the Kubota Group also conducts environmental audits to confirm that the environmental conservation systems and activities are properly implemented at each site, as well as environmental risk assessments to clarify the status of environmental risks and establish improvements, with the aim of preventing the violation of environmental laws/regulations and environmental accidents.
Despite these efforts, however, in FY2021 in Japan we had three cases of inappropriate processing of waste and, overseas, one case of wastewater exceeding regulation levels and one case of waste storage infringement. We investigated any impact on the ambient environment and are working to prevent recurrence. In addition, for the case of waste storage infringement that occurred overseas, a fine was levied.

The Kubota Group’s Environmental Management System

The diagram below shows the structure of the environmental management system of the Kubota Group.

1. Environment-related Rules and Regulations

The Kubota Group has formulated environment-related rules and regulations based on its internal control system, targeting Kubota Corporation, all of its consolidated subsidiaries and a part of its affiliated companies accounted for under the equity method that are highly significant in its environmental management.
The rules and regulations are classified as follows:

These rules and regulations are reviewed every year, according to the business environment and revisions of laws and regulations. The latest version of these rules and regulations are available on the Group portal site, allowing employees around the world to refer to them.

2. Investigation and Management of Environmental Data for Understanding by the Kubota Group

In order to practice environmental conservation activities on a global scale, the Kubota Group utilizes the “KUBOTA Ecology Data E-System” (KEDES) to collect environmental data, which includes information from our business sites on their energy usage, amounts of generated and discharged waste, water usage, and VOC emissions, etc.
“KEDES” is a system that collectively manages environmental data at global business sites. Staffs at each business site register monthly environmental data, which is used for target management of their own site. The Environmental Protection Department aggregates and analyzes the data, and uses it for reporting inside and outside the group. The boundary of the environmental data aggregation covers Kubota Corporation and all (100%) of its consolidated subsidiaries.

3. Environmental Auditing

Each year, the Environmental Protection Department conducts an environmental audit that incorporates a document audit targeting all production sites, service sites, offices, and construction and maintenance management departments in Japan, as well as overseas group production sites.
Moreover, in addition to the environmental audit by the Environmental Protection Department, annual internal environmental audits are conducted at production sites. Through these means, and by taking the initiative to self-check the status of environmental management, every effort is being made to further improve management levels.
All of the audit results are reported to the President and management at the Company-wide Risk Management Committee in accordance with the company-wide internal control system.

4. Environmental Risk Assessment

Environmental risks for facilities are evaluated from the function and management methods, etc., of environment-related equipment, and for facilities that are deemed to require countermeasures, risk reduction activities are promoted to strengthen equipment and management countermeasures until environmental risks are at an acceptable level.
The Kubota Group is proactively working to further reduce environmental risks by conducting environmental audits and environmental risk assessments - two activities with differing perspectives in parallel.

  • Environmental risk assessment

5. Environmental Patrols

At each site, environmental patrols are carried out to meticulously assess the entire site and confirm the absence or presence of conditions that may lead to environmental accidents or violations of environmental laws and regulations. The Kubota Group aims to reduce environmental risks by conducting environmental patrols and finding situations that may cause any abnormalities at an early stage.

  • Environmental patrol

6. Drills for Responding to Abnormal and Emergency Situations

The Kubota Group is working to identify and minimize environmental risks associated with its business activities through risk-specific response procedures.
We are also conducting drills each year based on response procedures that assume the outbreak of environmental accidents or situations that could arise in environmental accidents, in order to mitigate the impact on the ambient environment.

7. On-site Investigations of Waste Treatment Contractors and Purchasers of Valuable Resources

In order to promote the proper treatment of waste and other materials including valuable resources at its operating sites in Japan, the Kubota Group is increasingly employing the services of top-rated certified operators.
At the same time, the Group has stipulated internal rules for conducting on-site investigations of industrial and other recyclable waste treatment contractors as well as purchasers of valuable resources. As far as industrial waste where there are large numbers of treatment contractors, the Kubota Group conducted investigations using its own on-site investigation appointing system that is run by its production sites, offices, sales companies, and other companies.
In FY2021, due to the COVID-19 pandemic, on-site investigations were conducted only at sites where on-site checking was required due to local government ordinances and so forth. At other sites, we conducted investigations based on published information of treatment contactors and so forth. Looking ahead, we will continue to conduct investigations that increase validity to promote appropriate treatment.

Supplier Management

The Kubota Group promotes measures to protect the environment, working closely with suppliers who support our environmental management.
As a specific example of activities, Kubota Agricultural Machinery (Suzhou) Co., Ltd. (China) conducts “environmental patrols” of existing suppliers to verify compliance with environmental laws and requests suppliers to take recommended steps for addressing any points for improvement found with the goal of minimizing the risk of supply stoppages for procured components. For new suppliers, patrols are carried out prior to their approval, with only those verified as legally compliant selected as new suppliers.
