Green Products

During the fiscal year under review, USHIO has expanded the scope of its business activities based on the theme of creating safe, secure and environmentally friendly solutions to all business fields, including products, development and services. This shows that USHIO is aware of the social issues inherent in every aspect of its business activities, and is a manifestation of USHIO’s stance of being engaged with the issue of the application and deployment of the light technology that it has developed. Looking ahead, USHIO will continue to offer solutions on a global scale targeting medicine, health, the environment, energy, water, security, food and a host of other sectors. At the same time, we will strive to deliver high-value-added products and services that meet the needs of customers.

Fiscal 2017 Targets and Results of Phase Five of the Environmental Action Plan (Fiscal 2017 to Fiscal 2019)

Fiscal 2017 Targets

Target 1: Create 6 or more target solutions

Target 2: Initiatives to revise expressions based on the current sales unit basis


To accelerate the creation of green products, USHIO has been engaged in streamlining its organization, speeding up decision-making, simplifying rules, and formulating stricter standards

Fiscal 2017 Results

Result 1: Number of Super Green Products created: 12

Result 2: Identified indicators of ratio of green products among new products, and ratio of Super Green Products among new products


1. Group development: Expand green product activities to the domestic Group

2. Review of environmental factors: Examine the suitability of making environment factors for each business environment appropriate for Phase Six of the Environmental Action Plan

3. Achievement of new indicators: Conduct activities to improve green product ratio and Super Green Product ratio

Initiatives ahead

We have set goals for fiscal 2018 and will promote the following initiatives regarding green products and Super Green Products
・Ratio of green products among new products: 75% or more
・Ratio of Super Green Products among new products: 10% or more

Development of Environmentally Conscious Products

At USHIO, we incorporate our Environmentally Conscious Product Assessment Manual into our Design Standards so we can preevaluate the environmental impact of our products starting in the design stage. When the environmental performance of a product has been improved based on this evaluation, it is certified as an Environmentally Conscious Product. If a product is outstanding even among environmentally conscious products, and uses innovative environmental technology on a completely different level from existing products, it is certified as an SG product.

USHIO's System of Environmentally Conscious Products

Development of Super Green Products

In line with its efforts to create environmentally conscious products and based on its own certification standards, USHIO designates products that proactively use environmental technologies as Super Green Products. Super Green Products are flagship products that demonstrate excellent environmental qualities, such as energy efficiency, extended lifetimes, 3R design, materials used, and applications. USHIO has certified 31 Super Green Products that have cleared numerical benchmarks based on the USHIO environmental factor.

In fiscal 2013, USHIO proactively improved the environmental performance of product lines that take advantage of its unique strengths in light, certifying products such as optical measuring instruments, ultraviolet phototherapy devices for skin, LD light induced fluorescence light sources, ozone fumigators, LED light sources, UV irradiation units for hardening ink.

Evaluation Criteria of Super Green Products

The certification standard for Super Green products is comprised of the following three requirements.

1) Environmentally conscious product score of 80 or more (based on environmentally conscious product assessment standards)

2) Environmental factor of 1.5 or more (calculated in comparison to previous products, with fiscal 2000 as the baseline year)

3) Attainment of transparency

Environmental Factor

Environmental factor is calculated by dividing the environmental efficiency of the target product by the environmental efficiency of the equivalent product in the baseline year. USHIO calculates a product's environmental efficiency by dividing product value (performance) by environmental impact. Product value is calculated by multiplying energy output by lifespan. Environmental impact is calculated with this formula: √ [(Energy input)²+(3R volume)²+(Chemical substances content)²]

  • Notes:

  • 1. Energy output: For lamps, primarily lighting output and intensity. in the necessary wavelength range

  • 2. Energy input: Energy consumed in using the product

  • 3. 3R volume: Product size and weight (quantity of resources used)

  • 4. Chemical substances content: Quantity of substances with environmental risk contained in the product. For example, if the environmental factor is α for a given product, it signifies the following improvements over the baseline year

  • ・A product performance improvement by a factor of α, assuming the product environmental impact is held constant. A product environmental impact reduction by a factor of 1/α, assuming the product performance is held constant.

Actions Regarding Environmentally Friendly Products (Green Products)

When designing products, USHIO is required to conduct an environmentally friendly product assessment. This assessment of environmentally friendly products includes more than 60 points to be cleared, and we designate products that satisfy such necessary benchmarks, including improvement of environmental factors, as environmentally friendly products (green products).

Implementing LCA

No matter how much CO2 emissions are reduced at factories, these activities are not meaningful if CO2 emissions increase when the manufactured products are actually used by customers. Meanwhile, products can provide both cost and environmental benefits for customers if they use energy-efficient products. Therefore, to quantitatively measure the environmental impact of products and services over the entire lifecycle, USHIO formulated LCA guidelines in 2006 and has implemented LCAs ever since. In fiscal 2009, LCAs were implemented for all major USHIO lamp products. Going forward, we will expand LCA activities to various devices in order to satisfy the needs of customers.
