Design for Environment

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:① energy conservation, ② environmental conservation, ③ reducing, ④ reuse and recycling, ⑤ packaging, and ⑥ provision of information.
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.

Overview of the Evaluations

Evaluations via Checklists As indicated in the figure on the right, we perform quantitative evaluations for different items on a five-point scale in the aim of creating more products designed for the environment.


*Supplement to the evaluation items

2番 environmental conservation

We must meet standards like the REACH Regulations and ROHS Directive. But over and above these, we are aiming to meet our own, even stricter, voluntary standards.

6番 provision of information

We disclose environmental items that warrant attention as stipulated by law. On top of this, we aim to disclose information based on the guidelines of industry associations and the like.

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 above graph.
Our share of sales of environmentally friendly products has been rising year by year as a result of the increase in sales of headlamps that use LEDs, and now account for more than 65% of our products.


Products designed for the environment

Size and Weight Reduction

Through research into the materials used and other means, we are engaged in the development of smaller and lighter products that maintain the same levels of product life span and luminous efficiency. These smaller, lighter products are also contributing to the reduction of CO2 emissions, raw material usage reductions, and otherwise helping to reduce our environmental footprint in our manufacturing processes, transport, and end-of-life disposal.


Energy Conservation and Efficiency Improvements

In addition to adopting LEDs as the light source for automobile lamps, we are also engaged in the development of highly efficient, energy-saving products through the use of the light distribution technologies that are our strengths to achieve non-wasteful use of light. Our energy-saving products are helping to reduce CO2 emissions and contributing to the prevention of global warming.

Changes in headlamp power consumption (W/unit)


* Headlamp power consumption is measured not just for the low/high beams, but for the headlamp as a whole, including position lamps and turn signal lamps

Water Quality Preservation Initiatives

Stanley provide safe, secure water through UV sterilization. We are engaged in the development of high-output UV light sources, which have wavelengths that destroy bacteria efficiently. We contribute to water quality preservation through UV-LED and UV-CCL light sources and proposals for reactors and other applied products.

Water Sterilization Product Applications


Bidet-function toilets


Drink dispensers


Faucets and water purifiers

In addition to smaller, lighter, and highly efficient energy-saving products, we offer water sterilization products and are pursuing the development of environmentally-friendly products.
