Blue Value™ — Environmental Contributions

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.

The Goals of Blue Value™

The Mitsui Chemicals Group, whose Corporate Mission is “harmony with the global environment,” lists “a circular society in harmony with the environment” as one of its ideal future society and aims to realize this through its business activities. In our VISION 2030, we have established a basic strategy to bolster circular economy initiatives to transform our business structure through efforts such as building circular economy-based business models and rolling out circular economy-compatible products by transitioning to alternative raw materials and fuels. We seek to contribute to the realization of a low-carbon, circular society that coexists with nature by addressing challenges like climate change and the circular economy, alongside business growth.

As a tool to track progress, we have defined the environmental contributions of our products and services as Blue Value™, certifying those that meet our defined criteria through our assessment and review processes. By maximizing our contributions throughout the entire product life cycle through expanding and providing Blue Value™ products and services, we hope to achieve corporate growth for the Group and realize our ideal future society.

How We Assess Blue Value™

For impact assessment, we use a proprietary method based on LIME2*2, one of the environmental impact assessment methods based on life cycle assessment*1.

When certifying Blue Value™ products and services, we assess their environmental contributions from three perspectives: “Reducing CO2” “Conserving resources” and “Coexisting with nature.” These contributions are assessed as objectively as possible from two aspects: “Approach to social challenges” and “Our reasonable involvement.”

*1 Life cycle assessment (LCA):

A technique to quantitatively assess environmental impacts associated with all the stages of a product’s life, from raw materials, to manufacturing, processing, use, and disposal.

*2 LIME2 (Life-cycle Impact assessment Method based on Endpoint modeling):

Damage assessment-type life cycle environmental impact assessment method based on environmental conditions in Japan.

Approach to Social Challenges

(1) Scope of Evaluation

In the Blue Value™ initiative, we have established three contribution categories (certification item)—“Reducing CO2,” “conserving resources,” and “coexisting with nature”—based on the Group’s material topics, such as “Product design considering the entire product life cycle,” “climate change,” and the “circular economy.” These categories are derived from the impact areas of LIME2, a life cycle impact assessment method.

(2) Scenarios

When applying for certification, a scenario is created to determine how comparative assessments will be conducted within the specific supply chain relevant to the product or service. The review board confirms the appropriateness of the selected comparison targets by considering factors such as current technology and market conditions, including general products on the market, our own existing products, and approaches when there are no suitable comparison products.

(3) Evaluation Criteria

For the three contribution categories, we have established actions aimed at helping solve social challenges (decision item) from the perspectives of material use, energy consumption, waste emissions and other factors. These criteria define the types of data required to demonstrate environmental contributions and the information necessary to verify trade-offs. Based on this, the review board assesses whether the Group’s products and services sufficiently contribute to solving social challenges for the targeted contribution categories for certification. They also assess whether the actions taken result in any negative impacts in other areas, while considering the environmental impact across the entire life cycle of the products and services.

Additionally, if a product or service is deemed likely to be used to promote any socially harmful impacts, it is considered inappropriate for certification as a Blue Value™ product or service. In such cases, regardless of the individual contribution content, certification is avoided.

Examples of uses where certification is avoided

  • Tobacco (due to health concerns)
  • Fertilizer coatings (identified as a source of microplastics, which negatively impact the environment), etc.

(4) Simplifying the Assessments

In some cases, it can be challenging to gather all the necessary information to assess the environmental impact of downstream industries that use our products and services. In the Blue Value™ assessment process, we allow for the assessment based on certain approximations and assumptions to simplify calculations. The review board ensures that these approximations and assumptions are applied appropriately.

Our reasonable involvement

We evaluate the extent to which the Group’s products and services contribute to our approach to social challenges identified in the first stage of assessment. This evaluation considers not only the Company’s direct contributions, but also aims to visualize the broader impact across the supply chain, including processing by customers and the use of the final products.

Overview of Recent Review Results

At the FY2024 review board, 66 products and services were certified as Blue Value™. Chemical products derived from bio-based hydrocarbons and plastic raw materials made from recycled materials have been newly certified as Blue Value™. In addition, during the certification renewal review conducted every five years to reflect changes in societal demands and the market environment, products such as release films that improve product yields during press processing have been recertified.

On the other hand, applications that lack trade-off information, those that set comparison targets that do not take into account improvements in technological standards, and those that provide insufficient explanation of environmental contributions are deemed inappropriate and are not certified.

By applying this two-step assessment—considering both the approach to social challenges and our reasonable involvement, while also taking into account prerequisites and trade-offs—we strive to evaluate as objectively as possible whether a product or service truly contributes to solving social challenges. Additionally, we base our reviews on the advice and views from external advisors regarding the validity of certification in terms of the impact of social contribution throughout the entire supply chain.

External Advisors

When determining the assessment methods and review criteria for Blue Value™ products, we receive advice from Professor Norihiro Itsubo of the School of Creative Science and Engineering at Waseda University, who serves as an external advisor and provides insights from a specialist perspective. In addition, prior to the review board meeting, we also take into account his expert opinions on the level of contribution made by the applicant products, and the review board determines whether they meet the criteria.

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.
