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.

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 March 2015, we published the eighth edition of the Green Procurement Guidelines, which reflects the latest environmental laws and adds prohibited chemical substances to the list of designated chemical substances. 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 fiscal 2015, we held explanatory meetings for local staff and started green procurement at Cri-Tech Inc., a subsidiary of Daikin America, Inc. In addition, Goodman Manufacturing Company, L.P., Daikin’s air conditioner base in North America, carried out a green procurement survey at suppliers that work with Goodman Manufacturing Company, L.P., DAIKIN APPLIED AMERICAS INC., and AAF International, and compiled the results of the surveys.

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. As a result of these efforts, the green procurement rate in fiscal 2015 was 65%.

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.

Overview of Green Procurement Guidelines, 8th Edition

Essential conditions for suppliers’ management

  • Environmental Management System
    We request our suppliers to structure environmental management system to obtain ISO 14001 certification.
  • Compliance
  • Promotion of voluntary activities of improving environment energy conservation, waste reduction, and improvement of transport means.
  • Provision of information

Essential conditions for products

  • Chemical substance management
    1. Restriction on use of chemical substances
    2. Cooperation to investigation of chemical substances
    3. Voluntary reduction of substances ranked to reduce, and the implementation of adequate management procedures of them
  • Packaging materials
  • When designing work is involved, eco-friendly design must be employed.
  • Biodiversity
  • Protecting water resources

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 July 2015, the requirements for purchasing goods requiring chemical substances management (ASB040004K) were revised, with banned substances added and threshold management strengthened. The newly added banned substances are four kinds of phthalate ester*3, and BNST (Benzenamine, N-phenyl-, reaction products with styrene and 2,4,4-trimethylpentene)*4. 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.
