Blue Value™ — Environmental Contribution Value

Earth blue

Instead of green, which is associated with nature and ecology, blue represents something much bigger—the earth.
It is also our corporate color and signifies harmony with the global environment and our contributions to society.

Many chemical products pass through various stages; for example, they are manufactured and processed into end products and then disposed of after use. We assess how we can reduce a product’s impact on the environment at each stage of its lifecycle. By sharing this information with various stakeholders, we believe we can further contribute to environmental protection. With this idea in mind, we devised the Blue Value™ standard for environmentally friendly products in 2015 with the aim of achieving a circular society in harmony with the environment.
We use the Blue Value™ Index—our own LCA-based environmental impact assessment index—to evaluate products and services depending on their application and certify them as Blue Value™ if they significantly contribute to protecting the environment in the following three categories: (1) reducing CO2 ; (2) conserving resources; and (3) coexisting with nature.
We carry out comparative assessments against market-standard products and our existing product lineup because a requirement for Blue Value™ certification is that not only must the product have a higher score in either of the evaluation categories, it must not be inferior in all categories for each stage of its lifecycle. Moreover, the use of qualitative and semi-quantitative assessments means products can be easily evaluated, but whenever required, the department responsible for LCAs can technically and quantitatively assess the superiority of a product’s environmental contributions.
Blue Value™ products play an important role in the Mitsui Chemicals Group’s efforts towards material topics. We visualize the progress of our efforts in the areas of Climate Change and Circular Economy by utilizing the sales revenue ratio of Blue Value™ products as a KPI. Also, the life cycle assessment as a part of the Blue Value™ screening process examines the design of products and services from an environmentally conscious viewpoint to ensure designs that take account of the product’s impact throughout its life. We are sure that this achieves the comprehensive life-cycle considerations in our product designs.
The Mitsui Chemicals Group aims to realize a circular society in harmony with the environment through utilization of Blue Value™ criteria and increasing the number of Blue Value™ products and services.

  • 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.
