Environmental Policy

Yokowo is constantly assessing its environmenta footprint. We respect both customers’ environmental expectations and statutory requirements. We preserve the environment by employing an environmental management system and pursuing continuous environmental performance improvement.

Consideration of Environmental Impact of our Products

Committed to eliminating all substances that are hazardous to the environment and the human body, Yokowo Group has compiled a list of chemical materials to be controlled, performs product assessments from the design stage onwards that take environmental issues into account, and conducts comprehensive inspections of all parts and components at our domestic and overseas sites.

Through these activities, we have passed strict environmental requirements, such as the European Union (EU) RoHS Directive, and environmental audits by worldwide automotive and electronics manufacturers. This enables us to supply products conforming to global environmental preservation standards to customers around the world.

We are also launching a Group-wide activity to follow a more stringent green procurement policy and implement environmentally friendly production.

Identification and Reduction of Environmentally Hazardous Substances

Yokowo has identified 62 controlled substances such as lead, cadmium, chromium hexavalents, mercury, certain brominated flame retardants, and has set clear goals for each item: either complete elimina

tion or a reduction in use.

The materials and components used in our products are all subject to strict in-house checks, which include analysis by ICP and fluorescent X-ray spectrometers, to ensure that they contain no environmentally hazardous substances. In this way, we design and manufacture products to comply with environmental standards such as the EU RoHS Directive.
