Green Products

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 we are 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.
At the same time, we will actively reduce the impact on climate change by promoting environmentally friendly design and development that contributes to energy conservation and restraining CO2 emissions from all business activities.
Specifically, we have included an energy-saving item as one of Ushio's internal certification standards (Super Green Products), so we believe that we can continue to contribute to energy-saving by promoting sales of certified products.
We are also involved in the development of plant factories in order to see climate change as a new business opportunity and to meet the growing demand for stable food procurement that is expected under climate change.

FY2019 Targets and Results of Phase Six of the Environmental Action Plan

FY2019 Targets

For target SCOPE 3 (*1) , 1% reduction compared to FY2017


・Examining CO2 emissions of subject products and understanding the details of initiatives to achieve SCOPE 3's 2030 target.
・ Revise Super Green Product Standards and work to improve GP・SG ratio (*2) under our new standards
・ Expand solid state light sources products and scrutinize net sales ratio

FY2017 Results

・Re-calculations were conducted as we found necessity of adjusting the base value of FY2017.
・Careful examination of CO2 emissions of SCOPE 3 subject products
・Raised the Super Green Product Standard which led to the promotion of energy-saving product development. On the other hand, the certification rate of the super green product ended up at 60% of our target.  
・Conducted close examination of the sales ratio of solid state light sources


・We changed he base year of the Super Green product standards from 2000 to 2015 when solid-state light sources shifted to mass-production phase. As a result, the SG ratio was lowered, but we will promote further energy-saving and resource-saving development. 

Initiatives ahead

・Long-term target: By FY2030, reduce Ushio Group SCOPE 3 CO2 emissions by 33% compared to FY2017.
・FY2022 target: Set targets for the next Medium-term ESG Plan based on CO2 emissions of subject products 
・FY2020 target: Review CO2 emissions of subject products to determine SCOPE3 targets for 2030 

Development of Environmentally Conscious Products

At Ushio, we incorporate our Environmentally Conscious Product Assessment Manual into our Design Standards so we can pre-evaluate 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 FY2016, 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 FY2015 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.
