Environmental Conservation Activities
Product-based Environmental Contribution
In addition to reducing the environmental load generated at our company, we are also working to reduce the environmental impact at the consumer end-use stage in the life cycle of the products that we design, develop, and produce. The majority of CO2 emissions in the life cycle of fossil fuel-based vehicles are accounted for while the vehicle is driven. By improving vehicle fuel efficiency and providing parts for environmentally friendly vehicle such as EVs, we are contributing to the prevention of global warming and helping to reduce CO2 emission generated from vehicle use.
Initiatives for Environmentally Contributing Products
We have established an internal system to register and track products designed and developed in-house that contribute directly or indirectly (*) to environmental conservation. Our formula for calculating the total amount of environmental contribution is based on the contribution per product unit, and the number of units shipped.
(*)
| Category | Definition |
|---|---|
| Direct Effect | The size and weight of new products compared to the size and weight of existing products manufactured by us or other companies and the resulting improvement in fuel economy and reduced CO2 emissions. |
| Indirect Effect | The effect of reduced CO2 emissions resulting from the incorporation of our products into key components of our customers' energy-saving products (automobiles and motorcycles). |
Examples of Environmentally Contributing Products
Electric Power Steering Control Unit
It is a product that reduces the driver’s effort of steering wheel operation by control of an electronic motor to assist in turning the vehicle. Compared to hydraulic powered steering, it is characterized by its small size and light weight. CO2 emissions and fuel economy are improved by 3 to 5%. In addition, since no hydraulic oil is used, the environmental impact resulting from the eventual disposal of waste oil is eliminated.
DC/DC Converter for Idling Stop System
In vehicles designed to turn off the engine while stopped at a light or idling, this product maintains a stable voltage and prevents a voltage drop from the battery that occurs when the engine restarts. Idling stops help save fuel and reduce emissions.
DC/DC Converter for xEV
This product converts the high voltage of high-voltage batteries installed in EVs, PHEV, etc. to low voltage needed to supply power to various electrical equipment and low-voltage batteries in the vehicle. This product contributes to increasing acceptance and adaptation of environmentally friendly vehicles such as EVs.
