Contribution to CO2 reduction through products

*The calculation method for the contribution amount of CO2 reduction has been partially changed since FY2016.
JTEKT has established its own formula to calculate environmental efficiency, and the formula is used as an index of quantitatively assessing the reduction volume of environmental burden. The value calculated by the formula indicates how much the environmental burden is reduced. Each year, JTEKT sets higher targets and endeavors to achieve it, monitoring the achievement level.
●Environmental efficiency basic equation and environmental efficiency value calculation
Environmental efficiency is a value calculated based on the degree of lightness, compactness, energy-savings, etc. The environmental efficiency value is calculated by dividing the environmental efficiency of the assessed product by that of the standard product.
●Calculation of environmental load reduction effect
As the environmental load reduction effect, it is possible to seek environmental load reduction ratio more than the environmental efficiency value. For example, if the environmental efficiency value was 1.25, that product’s environmental load reduction benefit would be 20%.A reduced environmental load is sought as the reverse of the environmental efficiency value.



3R initiatives
JTEKT’s business headquarters and group companies work together as one to promote environmental design activities.
Through the incorporation of creative ideas from the design stage, JTEKT group products contribute to the global environment.
In addition to producing new TOYODA grinders and overhauling used grinders, JTEKT is newly developing rebuilt machines to expand into its business.
Rebuilt grinders are scrapped TOYODA grinders that JTEKT obtains from the marketplace, revives using TOYODA’s accumulated technologies, skills, and experiences, and sells to the general public in the same way new machines are sold.
While rebuilt grinders are as precise as new machines, they are sold at 70% of the cost of new machines and available for immediate delivery.
Additionally, the cast iron, steel, and other materials forming the bed that had previously been discarded are reused, significantly reducing the environmental load.
