Environmental Risk Management

Auditing and Improving Compliance with Environmental Laws and Regulations

Once a year, the Daikin Group in Japan has company-wide environmental auditing teams conduct audits to check for legal compliance and ensure there are no environmental risks.

We have systems in place that allow us to minimize environmental damage if there should be an accident or calamity at the production site of Daikin or a subsidiary.

We also maintain close relations with neighborhood associations through factory tours and other activities so that we can have a joint system of emergency measures with local communities.

Drills Held to Prepare Chemical Plants for Accidents

We have systems in place that allow us to minimize environmental damage if there should be an accident or calamity at Daikin production sites around the world. The Chemicals Division and machinery divisions created the Disaster Prevention Manual, which details how to deal with emergencies like chemical and oil leaks and spills. The manual is the basis for regular emergency drills.

In fiscal 2015, the machinery divisions held training that simulated chemical or oil leaks from delivery trucks in the machinery divisions, which included initial response and identifying the cause of the leaks. In the Chemicals Division, activity areas were divided into three zones: a hot zone, a warm zone, and a clear zone, so that provisions could be made for things like preventing the spread of pollution from hazardous substances and protecting workers from harm.

Close Communication with Communities to Prepare for Emergencies

We place the utmost priority on ensuring the safety of residents living near our plants. Particularly with regards to facilities like our Yodogawa Plant, which is located in a residential area, we use risk assessment to eliminate as much risk as possible.

We also strive to keep the public informed and communicate with government organs based on the principles of responsible care*. We have conducted regular exchanges with the public through neighborhood community association gatherings and plant tours, and we are working to establish systems of communication with these bodies so that both Daikin and the surrounding communities are prepared for emergencies. In fiscal 2014, we joined a conference for dialogue on current events in Osaka to present a report on Daikin’s preparations for a possible major earthquake in the Tonankai and Nankai regions of Japan.

Under an agreement between our Shiga Plant and the local municipality of Kusatsu, we reported the findings of one year of analysis and measurements of air, odors, water quality, sewage, noise, and vibration.

* Responsible care: An initiative by the chemical industry in which companies strive to improve their environmental, safety and health performance in all stages from development and production to distribution, use, and final consumption of chemicals. It also covers disclosure of the results of these efforts in order to keep the public informed.

All Production and Use of the Fluorochemical Product PFOA and Similar Compounds Ended in 2015

At the end of 2015, as part of its efforts toward sustainable management of chemical substances, Daikin Industries, Ltd. ceased manufacturing and using PFOA and similar compounds, as well as products made from these.


Monitoring Environmental Standards

Strict Management at Manufacturing Bases Exceeds Legal Restrictions

The Daikin Group controls air and water pollution, as well as noise and vibration, using voluntary standards that are stricter than national environmental standards and local government by-laws. We regularly measure our various environmental impacts and work to either prevent or decrease them.

Monitored environmental data for Daikin Industries, Ltd.'s four manufacturing bases is on the Daikin Web site.


Measures for Soil and Groundwater Pollution

Dealing with Soil Pollution at the Yodogawa Plant

A soil pollution survey at the Yodogawa Plant revealed pollution of soil and groundwater from substances such as VOCs and fluoride. The polluted soil was closed up and the groundwater was pumped up and purified. Surveys in recent years have revealed that the pollution concentration of the tetrachloroethylene and trichloroethylene used in the center of the site in the past has decreased; however, the concentration of dichloroethylene, which is generated when these two substances naturally break down, has increased. This occurs during the purification process, and pumping up the groundwater has prevented this from spreading beyond the boundaries of the site.

In addition, in 2013 the site was designated by the Osaka Prefectural Government as an Area for which Notification is Required upon Change to Form or Nature* (under Japan’s Soil Contamination Countermeasures Act), and construction work was subsequently carried out. All work was completed at the end of December 2015, and Daikin Industries, Ltd. applied to the government to have the site where the polluted soil was cleaned to be taken off the list of designated sites.

* Area for which Notification is Required upon Change to Form or Nature:
A designation under Japan’s Soil Contamination Countermeasures Act in which as a result of a soil pollution survey, non-conformance is discovered but the land is not suspected of posing a health hazard.

Groundwater Cleanup Continues at Kashima Plant

In 2000, the concentration of organic chlorine-based compounds in groundwater at the Kashima Plant was found to exceed environmental standards. We therefore removed and cleaned the contaminated soil, pumped out and cleaned the groundwater, and took precautions to prevent pollution from spreading to outside the plant and to remediate all types of pollution.

Ongoing cleaning of the groundwater has resulted in reduced concentrations of pollutants. We will continue these cleanup efforts to bring the levels down to within environmental standard values.


Storage and Treatment of PCBs

Implementing Strict Management and Disposal of Equipment Containing PCBs

Daikin abides by national laws in properly managing equipment containing PCBs (polychlorinated biphenyls). We have already begun disposing of some of this equipment through early registration with the Japan Environmental Safety Corporation (JESCO) and based on a JESCO PCB disposal plan.

In fiscal 2013, we finished disposing of all condensers at the Yodogawa Plant. In fiscal 2014, we had a contractor reconfirm ballasts for lighting, and results showed that 350 of them contained PCBs. We plan to dispose of these starting in 2016. We are continuing to store equipment containing no PCBs, and we will dispose of it following completion and submission of revised paperwork to the government in the next fiscal year.
