Attitude toward Promoting Green Procurement

ROHM Group recognizes the importance of natural capital as stated in its environmental policy, and has made the promotion of efforts that contribute to and take into consideration the global environment as an important management issue. Aiming for the sustained development of society without destroying the global environment requires recycling business activities with a lower impact on the environment. ROHM Group not only complies with environmental laws, regulations, treaties and international guidelines throughout the entire supply chain, but is also engaged in the procurement of environmentally friendly parts and materials.

As legal regulations on the management of chemical substances become increasingly stringent, ROHM Group has worked to increase the precision of investigations of chemical substances contained in the parts and materials it procures to promote green procurement. The Group has created a system for not procuring prohibited substances by screening the substances contained in parts and materials by referring to ROHM’s own standards and only registering those that meet the standards in the “Procurement System” as allowed products. Furthermore, in order to ask suppliers to conduct thorough management of chemical substances contained in products, ROHM Group issues green procurement guidelines and product chemical substance management standards, and asks them to confirm compliance with the designated standards for the parts and materials handled.

Past Activities

FY2019 We distributed the Survey of Chemical Substances Contained in Products to 512 suppliers and received responses from 489 companies.
FY2020 As a result of the evaluation based on ROHM's own standards, there were some items that did not meet the requirements of three suppliers.
FY2021 As a result of their efforts to improve corrective actions, two suppliers met ROHM's required standards.
FY2022 Conducted periodic self-assessment using the Survey Sheet for Chemical Substances Contained in Products once every three years.
The number of companies subject to the survey has been reduced due to close scrutiny of the supply chain.
In addition, for suppliers that did not meet some of the requirements this time, we have started activities for improvement by identifying issues and sharing the situation with them.

For the future

  • ・From FY2023, ROHM Group-level assessment is scheduled to be implemented.
