Initiatives for Environmental Quality about Product

Environmental Management

ROHM Group has been making efforts through its business activities including the development of environmentally-conscious products and Product Chemical Substance Management in order to realize a sustainable society.

Development of Eco-Friendly Products

・Increase the Development Ratio of Eco-Friendly Products

With a goal of resolving social issues through innovative products, ROHM Group has developed an environmental contribution evaluation sheet to numerically and objectively assess the extent to which new products contribute to the environment compared with previous models in the new product development stage, and has built a system for comparing environmental and CO₂ reduction performance. In particular, the introduction of a mechanism to improve the development ratio of eco-friendly products that can reduce CO₂ emissions during usage is being promoted in collaboration with the development department.

2020 Environmental Targets


With the scientific techniques and various kinds of calculation tools including LCA, CO₂ reduction activities are promoted.
By developing the environment-friendly products in alignment with 'NEXT50', contribution to the CO₂ reduction at the time of use is considered.

[Medium-term Target and Final Results]

Medium-term Targets Final Results
Reduce CO₂ emission through the value chain by 10% from the actual results of FY2010. Reduced by 10.3%
Increase the ratio of environment-friendly products developments to 100%. 100%

Development of Eco-Friendly Products

Product Chemical Substance Management

ROHM Group complies with all environmental laws and regulations in Japan and overseas along with customer requirements and conducts initiatives to procure materials that minimize environmental impact.
While regulations on product chemical substance management such as the EU RoHS Directive, EUREACH Regulations, and the China RoHS Directive are being further strengthened, we have established Green Procurement Standards and verified conformance to each regulation by accurately obtaining the chemical information contained in raw materials and parts.
Based on the cooperation of our business partners, we are promoting the creation of eco-friendly products, creating a management system that prevents prohibited substances from being received, used, or shipped, and supplying products that ensure worry-free use by our customers.
In addition, raw materials and parts delivered from suppliers as well as products to be shipped to customers are periodically checked for chemical substances using fluorescent X-ray analyzers installed at each production site and at ROHM's Quality Assurance Department.

In 2004 ROHM completed the transition to lead-free to ensure compliance with the RoHS Directive (2002/95/EC) enacted in 2006 (excluding some custom products demanded by certain customers). ROHM products also comply with the revised RoHS Directive (2011/65/EU) promulgated in 2011 and the additional directive ((EU)2015/863) established in 2015 restricting the use of specific phthalate esters.
Please note that our products do not contain restricted substances exceeding the maximum permissible concentration except for those exempt from regular applications.
