To minimize the impact of our products and services on the environment and achieve harmony between the environment and the creation of abundant value, we are taking measures to save energy, use resources efficiently, and prevent pollution throughout the product life cycle, reducing our environmental footprint globally.
Life Cycle Assessment (LCA)
Promoting design for the environment through the use of a checklist
In order to promote the manufacture of products designed for the environment we use our Design for Environment Guidelines and apply them to the full range of our product design. We perform evaluations through the use of checklists in order to reduce our impact on the environment to the extent possible.
We revised our approach to evaluating these in FY 2017 and now use a six-item checklist that includes: ①energy conservation, ②environmental conservation, ③reducing, ④reuse and recycling, ⑤packaging, and ⑥provision of information. Our designers personally quantify and evaluate these in an effort to improve our environmental friendliness.
What is more, our checklists allow us to determine the CO2 emissions given off in every step from the selection of the raw materials to the manufacturing of the product and its delivery to customers.
Changes in the proportion of products designed for the environment
The percentage of our sales accounted for by products designed for the environment over the past five years is shown in the graph on the left.
For FY 2017, headlamps using LEDs continued to increase, due to which the sales ratio of our products designed for the environment grew, and such products came to account for 65% of our products.
Design for Environment
- Reductions in product size and weight
- We are developing LEDs using materials that achieve smaller size and lighter weight without sacrificing lifetime and luminous efficiency. These smaller, lighter products help reduce the environmental burden in manufacturing, transportation, and disposal, producing fewer CO2 emissions and making less use of raw materials.

- Power saving and improved efficiency
For automotive lamps, besides using LED light sources, we are taking advantage of our advanced light distribution technology to use light less wastefully, developing products that are highly efficient and save energy. Energy-efficient products result in lower CO2 emissions and help prevent global warming.

For LED floodlights, our unique light distribution technology is used to produce highly efficient super-narrow beams that save energy.
We will continue our efforts to provide environmentally friendly products that are smaller, lighter, and more energy-efficient.
