Blue Value™ / Rose Value™

Sharing environmental contributions through Blue Value™

With Blue Value™, the environmental contributions the products and services provide throughout the life cycle can be visualized.
For example, Blue Value™ certified products related to the automobile industry reduce environmental impact not only in processes the Mitsui Chemicals Group is directly involved in such as raw materials procurement and manufacturing, but also in various life stages including intermediate processing where it is indirectly involved as well as the use and disposal of the end products.

Maximization of environmental contributions throughout the Life Cycle
- Hypothetical Case: Products Used in Automobiles -

*The image is a hypothetical case and may differ from information on actual products of our Group.

The Group aims to maximize the environmental contributions generated from implementation of Blue Value™ products and services in the society, by sharing this value or “Blue Value™” with various stakeholders throughout the life cycle.

Blue Value™ Assessment Index and Certification Criteria

Blue Value™ is assessed based on three contribution categories: (1) reducing CO₂; (2) conserving resources; and (3) coexisting with nature. For each contribution category, Blue Value™ Index, which is the Mitsui Chemicals Group’s unique assessment index simplifying LIME2, is set to evaluate the environmental impact throughout the life cycle in comparison with general products in the market and our existing product lineup. Blue Value™ products and services are certified through discussions by the review board based on criteria that in addition to the environmental contributions being recognized at a sufficient level throughout the life cycle in more than one of the three contribution categories, no negative impact occurs in any of the contribution categories.
Evaluation using the Blue Value™ Index is qualitative or semi-quantitative, but there is a system for collaborating with the department responsible for LCA to conduct a stricter and quantitative assessment whenever required.

Environmental Impact Assessment Index — Blue Value™ Index

Contributions	Blue Value™ Index
	Assessment index	Related assessment items
Reducing CO2	Reduction of GHG emissions Reduce GHG emissions at the raw materials acquisition, manufacturing/processing, and end products use/disposal stages. Saving of energy, electricity, fuel Reduce energy such as electricity and fuel at the raw materials acquisition, manufacturing/processing, and end products use/disposal stages. Use of end products in the energy conservation field.	Weight and volume reduction Long service life Natural energy sources Non-fossil raw materials Environmental cleanup
Conserving resources	3Rs, ease of sorting, conservation of resources Use reusable/recyclable materials at the manufacturing/processing stages for products, processed items, and end products as well as reduce material usage. Products, processed items, and end products based on reuse/recycling. Possible separation at the time of disposal.
Coexisting with nature	Ecosystem conservation (human health) Reduce the impact on human health from chemical substances across product lifecycles; specifically, reduce the addition of chemical substances harmful to human health, curb their formation, use chemical substances that are less toxic, and use end products in the health & safety fields. Ecosystem conservation (environmental organisms) Reduce the impact on ecosystems from chemical substances across product lifecycles; specifically, reduce the addition of chemical substances harmful to ecosystems, curb their formation, use chemical substances that are less toxic. Prevention of environmental contamination Reduce the impact on the global environment excluding people/living organisms from environmental pollutants across product lifecycles; specifically, reduce the addition of environment pollutants harmful to ecosystems, curb their formation, and use substances that do not pollute the environment.

*Related assessment criteria are evaluated on contributions to any one of the assessment index.

*GHG emission-related global warming substances, chemical substances harmful to ecosystems, and environmental pollutants are all substances for which characterization factors have been calculated in LIME2.

Example of Blue Value™ Evaluation, Review, and Certification

Target Product: AdBlue™^*1
Application: NOx reducing additive
Comparison: Vehicle equipped with urea SCR system vs Vehicle not equipped with urea SCR system

This table is scrollable.

*1AdBlue™:
“High-grade aqueous urea” used in diesel engine cars equipped with urea SCR system which reduces nitrogen oxides (NOx) contained in exhaust gas. Under strict quality control, we manufacture and supply the highest quality AdBlue™ made from 100% pure domestic urea and deionized water. The raw material urea is manufactured in our Osaka Works, with a firm supply system that is not easily impacted by external factors.

*AdBlue™ is a registered trademark of the VDA (Verband der Automobilindustrie)

*2Secondary effect:
Internal combustion engine used in combination with the urea SCR system is designed as a high-temperature combustion, which improves fuel efficiency compared to conventional internal combustion engines and reduces GHG emissions.

The product concept of AdBlue™ is the reduction of NOx in exhaust gas when used in diesel engine cars equipped with urea SCR system. Results from evaluation based on the Blue Value™ Index show that environmental impact (urban air pollution and acidification) improved by about five folds, which led to its certification as a Blue Value™ product for its environmental contributions in “Coexisting with nature.” Additionally, vehicles equipped with urea SCR system using AdBlue™ have improved fuel efficiency compared to vehicles not equipped with the system. Therefore, AdBlue™ is also certified for its environmental contributions in “Reducing CO₂,” as it contributes to GHG emission reduction. Thus, by evaluating throughout the life cycle using Blue Value™, the content and effects of the environmental contributions are shared with customers and stakeholders.

Expectations from external expert (Blue Value™ advisor)

Decarbonization and a circular economy are central to solving the world's problems, as well as to corporate growth strategies, and businesses need to promote cross-industry eco-innovation.
Blue Value™ helps visualize the reduction in environmental impact of products from a product life cycle perspective. This is extremely important information for quickly achieving a carbon neutral and recycling-oriented society.
Mitsui Chemicals has adopted the sales revenue ratio of Blue Value™ products as a key performance indicator for its long-term business plan targets, which contributes to the rapid spread of eco-products. So, I strongly support its activities.
