Environmental Management

Based on its internal control system, the Kubota Group is establishing environmental management systems at each site and enhancing its risk management activities. In recent years, we have engaged in activities to strengthen environmental management at our overseas sites.

Compliance with Environmental Laws and Regulations

To ensure compliance with environmental laws, the Kubota Group has set and thoroughly manages its own control values at each of its sites for exhaust gas, wastewater, noise, vibration and other variables that are stricter than the relevant laws and regulations. We have established a system to promptly report any non-compliances and complaints related to environmental laws and regulations to the head office.
 Despite these efforts, however, in 2016 we had a case of exceeding of the wastewater control value and a case of inappropriate treatment of PCB-containing devices at production sites in Japan, and a case of the leakage of cooling water at a Group company in Japan. Moreover, in 2017 a case of exceeding the wastewater control value arose at a production site in Japan. None of these cases resulted in any serious incidents, and we implemented necessary measures to prevent any impact on the ambient environment and are working to prevent recurrence.

Environmental Auditing (Implementation status in RY2016)

Each year, the Kubota Environmental Protection Department conducts an environmental audit that incorporates a written audit targeting all production sites, service sites, offices, and construction and maintenance management departments domestically, 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 in an effort to further improve the level of environmental management.

Environmental Risk Assessment (Implementation status in RY2016)

Each year, detailed environmental risk assessments are conducted to evaluate the use of hazardous substances and the functions of environment-related equipment with the aim of clarifying the status of environmental risk at each production site and establishing systematic improvements.
 The Kubota Group is proactively working to reveal possible environmental risks and further reduce risk by conducting environmental audits and environmental risk assessments—two activities with differing perspectives—in parallel.

[Assessment targets]

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. In RY2016, Kubota formulated the Environmental Patrol Handbook, which provides the key points with which even unexperienced personnel can notice abnormality during environmental patrol, and distributed it to each site in Japan. Kubota aims to reduce the environmental risks by conducting the environmental patrol using this Handbook and finding the situation that may cause any abnormality in an early stage.

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.

Environmental Achievement Awards

During the Environment Month in June every year, the Kubota Group presents the Environmental Achievement Awards to praise the individuals and groups that have made notable contributions to environmental conservation, as well as to boost the Group's employees' environmental conservation awareness and activate their environmental activities.
 In RY2016, the scope of the awards was expanded to include non-production sites and product development departments in addition to production sites, and various environmental conservation activities including education and enlightenment, and social contribution, were evaluated. As a result, 24 cases were awarded for their achievements in energy saving, waste reduction, VOC emissions reduction, development of environment-friendly products, environmental awareness raising, community environmental activities, etc. Two of them were awarded as Excellent Prize.
 We will continue to award the excellent initiatives that contribute to the environmental conservation, and encourage sharing of the details of such initiatives within the Group, with the aim of further activating the environmental activities.
