Environmental Contribution Value, Blue Value

Numerous chemical products pass through a variety of life cycles, from manufacturing and processing to final disposal after use. At each life cycle stage, we visualize from the perspective of product stewardship how much we can reduce environmental impact and share this with a wide array of stakeholders, a practice that often leads to further environmental contributions. It was with these ideas in mind that we developed the environmental contribution value, Blue Value, in 2015 in order to achieve our goal of realizing a “cohesive society in harmony with the environment”. Under the unique environmental impact assessment criteria Blue Value Index, the Mitsui Chemicals Group certifies products and services as having Blue Value that are deemed to reduce CO2, protect resources, and harmonize with nature, thereby contributing to the environment in three elements.
Conducting comparative assessments targeting market-standard products and existing in-house products, Blue Value comprises certification requirements that not only involve passing evaluation standards but also not falling below these at each life stage. In addition, Blue Value incorporates qualitative and semi-quantitative assessments while becoming a system that enables simplified evaluations. On an as needed basis, Blue Value has become a framework to assess the superiority of specialized and quantitative environmental contributions by departments responsible for LCA*.

*LCA(Life Cycle Assessment):
A method of quantitatively assessing the environmental impact of products at all stages, including development, manufacturing, transportation, use, and final disposal.

Contribution Elements Environmental impact assessment criteria Blue Value Index
Evaluation criteria Related assessment criteria
Reduce CO2
Reduction of
GHG emissions
  • Reduce GHG emissions at the raw materials acquisition, manufacturing/processing, and end products use/disposal stages
  • Weight-saving / Volume reduction
  • Extended service life
  • Natural energy sources
  • Non-fossil raw materials
  • Environmental cleanup
The above are assessed on contributions to all evaluation criteria
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
Protect resources

3Rs, easy sorting,
resource
conservation
  • 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
Harmonize 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

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