Daikin Group Requests that Worldwide Suppliers Abide by Green Procurement Guidelines

The Daikin Group established its Green Procurement Guidelines in fiscal 2000 and requires suppliers in Japan and overseas to abide by these in the procurement of materials and parts used in manufacturing.

We mark suppliers on environmental protection activities using a green procurement checklist. In addition, the ErP Directive obligates manufacturers of energy-using and energy-related products (ErP) to reduce their energy consumption. To comply with this directive, Daikin's green procurement survey for suppliers determines energy-induced CO2. To this survey we have added criteria such as biodiversity and water resource protection.

We are discussing individual measures that will remedy the particular problems of suppliers, and those who get a perfect score on the survey are evaluated as 'green suppliers'.

In January 2017, we published a revised version (9th edition) of our Green Procurement Guidelines, which reflects the latest environmental laws and adds prohibited chemical substances to the list of specified chemical substances. In addition, in order to comply with the increasing number of third-party environmental management certification systems, such as the Ministry of the Environment’s Eco-Action 21, the KES Environmental Management System Standard, and ECOSTAGE, the latest Green Procurement Guidelines are not limited to just ISO 14001 certification but also include efforts aimed at certification for these other systems. And because responses by Daikin’s CSR & Global Environment Center to an external assessment revealed possible shortcomings in Daikin measures for protecting water resources in the supply chain, the Green Procurement Guidelines include assessment items for biodiversity and water resource protection.

We will continue to revise these guidelines to reflect changing environmental laws and situations.

Calls for Improvement and Guidance at Overseas Bases

We hold meetings for suppliers to explain the importance of green procurement in order to further raise the green procurement rate. At divisions in Japan and at bases overseas, we are striving to make green procurement a firmly rooted part of doing business.

In 2016, our South American bases followed the North American bases in embarking on green procurement activities. In Thailand, China, and Europe, suppliers evaluated at a rank of “B” or lower were requested to make improvements and were given guidance in doing so. Although results of green procurement surveys at overseas bases have been varied, we are continuing to request that suppliers in question take steps to improve.

Green procurement surveys in Japan added points-based criteria on biodiversity and water resource protection, but many suppliers have not taken any measures for these areas yet and the rate of green suppliers has decreased. In fiscal 2016, the green procurement rate in Japan was 91%.

As a result of these efforts, the green procurement rate in fiscal 2016 was 74%.

The requirements for green procurement have been gradually increasing to include items such as banned chemical substances and protection of biodiversity and water resources, and every year surveys are becoming increasingly strict. Although there are cases in which the green procurement rate, which shows the results of survey, goes down, rather than focus only on such numbers, we believe that it is more important to ensure that surveys lead to suppliers improving based on the latest edition of the green procurement checklist. We will continue holding explanatory meetings at overseas bases and aim to raise the green procurement rate in regions where it is low.

Compliance with Restrictions on Toxic Chemicals

Establishing Standards for Managing Chemical Substances in Products

The Daikin Group has a list of SVHC (substance of very high concern) based on the RoHS Directive*1 and the REACH Regulation*2 regarding chemicals contained in products. These are stated in our Green Procurement Guidelines, which we require our suppliers to abide by.

In our latest Green Procurement Guidelines (9th edition), we have altered our list of specified chemical substances. In particular, because starting in July 2019 four phthalates esters*3 will be banned in the EU as RoHS 2 restricted substances, under the Green Procurement Guidelines (9th edition) the Requirements Related to Specific Chemical Substances (ASB040004L), these substances, along with BNST (Benzenamine, N-phenyl-, reaction products with styrene and 2,4,4-trimethylpentene)*4, have been newly prohibited.

Furthermore, in July 2016, the requirements for purchasing goods (ASB040004L) was revised, with EU biocide rules newly added.

*1 The RoHS Directive (Restriction of Hazardous Substances Directive) is a regulation in the EU prohibiting the use of certain hazardous substances in electrical and electronic equipment.

*2 The REACH Regulation on chemical substances went into effect in Europe in June 2007. REACH obligates companies manufacturing or importing at least 1 ton of chemical substances a year in the EU to register with EU authorities. REACH covers almost all chemicals on the market in the EU.

*3 As of March 31, 2015, under the EU Directive EU2015/863, four kinds of phthalate ester were added as controlled substances. These will be restricted under the directive from July 22, 2019, but the Daikin Group will cease using them in production starting on January 1, 2019.

*4 As of March 14, 2015, BNST (Benzenamine, N-phenyl-, reaction products with styrene and 2,4,4-trimethylpentene) is prohibited under the Canadian Environmental Protection Act.

*1 The use of TBTs and TPTs is prohibited in the EU. Tin concentration must be 0.1% or less. The use of DBTs is prohibited in the EU. Tin concentration must by 0.1% or less. The use of DOTs is prohibited in the EU. However, only "Commodities that touch the skin" and "Two-component normal temperature cured sealing material" will be prohibited. Tin concentration must by 0.1% or less.

*2 Under the POPs Agreement of May 2009, PFOS was added to Appendix B (prohibited substances). In October 2009, PFOSs were added to the list of class I specific chemical substances under revisions to Japan's Law Concerning the Evaluation of Chemical Substances. Prohibited as of April 2010 under Japan's Law Concerning the Evaluation of Chemical Substances (except for applications in semiconductors, etching, and business photographic film).

*3 The use of F gas (HFC, PFC, etc.) is prohibited in one-component foams (banned in the EU starting on July 4, 2008.) However, the use of F gas (HFC, PFC, etc.) is permitted for refrigerants.
