Commitment to Nature Positive
The ongoing destruction of ecosystems and environmental changes are accelerating species loss, which in turn undermines biodiversity. Recognizing that all human civilizations depend on Earth’s ecosystems, the Mitsubishi Electric Group is committed to advancing nature positive initiatives.
Biodiversity Preservation Activities
Biodiversity Action Guidelines
The Mitsubishi Electric Group has established Biodiversity Action Guidelines which define the role its business activities will play in preserving biodiversity. We are committed to taking action to help build a sustainable world.
Assessment of Impact of Business Activities on Biodiversity
The Mitsubishi Electric Group identifies and evaluates the environmental impact of our business activities under an environmental management system based on materiality assessment and third-party certification (ISO 14001). As a result, no significant impact on biodiversity has been confirmed at this time. Furthermore, the Mitsubishi Electric Group's business activities do not involve any direct or indirect use of animals, and we promote initiatives that do not rely on animal testing or the keeping and use of animals in any of our product development, testing, or procurement processes. In the event of any change in our business activities, we will reassess the impact on biodiversity and implement management measures as necessary.
Biodiversity Preservation Measures at Business Sites
The Mitsubishi Electric Group has set forth three courses of action as guidelines for biodiversity conservation activities at its business sites: A. Reducing negative impact on living creatures; B. Aiming for more fruitful symbiosis with living creatures; and C. Restoring the relationship between employees and nature in the working environment. At each business site, action plans provide for the preservation of local indigenous species, control of alien species, and development of green space in consideration of the surrounding ecosystem, to ensure these initiatives are steadily addressed in all businesses.
Three courses of action
| Courses of action | Examples | |
|---|---|---|
A Reducing negative impact on living creatures |
1. Controlling development pressure*1 and alien species pressure*2 *3 | (1) Assessment of impacts on living creatures |
| (2) Alien species control | ||

| (3) Development of priority land for greenery and living creatures | ||
| (4) Provision of continuity of greenery with areas surrounding business sites | ||
| (5) Contribution to biodiversity preservation activities in areas surrounding business sites | ||
| 5. Breaking away from agricultural orientations such as simplifying/specializing greenery | (1) Diversification/multi-stratification of vegetation | |
| (2) Management of greenery that accords with the characteristics of plants, etc. | ||
| (3) Contribution/consideration to regions | ||
C Restoring the relationship between employees and nature in the working environment |
6. Proactively utilizing ecosystem services in the workplace (break rooms, individual floors) | (1) Provision and utilization of opportunities for cultural services |
| (2) Provision and utilization of opportunities for supply services | ||
| 7. Changing situation from everyone being disinterested and unrelated to everyone being involved | (1) Education for understanding and promoting action | |
| (2) Creation of relationships through the workplace or work duties | ||
- 1 The impacts on biodiversity conservation arising from constructing new business sites or undertaking development activities, such as natural-resource extraction (including those in the supply chain). This covers cases where operational water use affects surrounding areas, water sources, and ultimately the habitats of living organisms.
- 2 The introduction of non-native species into an area by planting trees, shrubs, or other vegetation sourced from outside the region, which can threaten the survival of indigenous species and lead to genetic contamination.
- 3 Activities are carried out pursuant to the regulation on raising, planting, storing, carrying, or other handling of specified IAS in the Invasive Alien Species Act.
Quantitative Assessment Based on the Biodiversity Guidelines (Check Sheet)
At Mitsubishi Electric, we employ the Biodiversity Guidelines (Check Sheet) to quantitatively assess each business site’s biodiversity initiatives. The Guidelines cover 186 promotion items—five mandatory items for all sites and seven areas (subcategories) aligned with the courses of action outlined above—and measure implementation levels for each item. This check sheet is used by personnel in charge at each business site to self-assess the status of biodiversity initiatives and identify strengths and issues in order to steadily improve their efforts.
Five mandatory items for all business sites
- A person in charge, the department in charge, and specific operations for promoting biodiversity initiatives have been identified.
- There is a medium-term plan for conducting biodiversity preservation activities.
- Biological surveys are conducted.
- Environmental education on biodiversity is provided every year.
- Feedback is given regarding the medium-term plan.
Seven areas based on courses of action
- Controlling development pressure and alien species pressure
- Calling attention to and preserve rare species and endemic species
- Managing the impact of pesticides, and preserving greenery and natural resources
- Setting up functional greenery
- Breaking away from agricultural orientations such as simplifying/specializing greenery
- Proactively utilizing ecosystem services in the workplace (break rooms, individual floors)
- Changing situation from everyone being disinterested and unrelated to everyone being involved
Nationally Certified Sustainably Managed Natural Sites
To contribute to achieving the 30by30 target*1 through our biodiversity conservation activities at business sites, Mitsubishi Electric is advancing efforts to secure certification as Nationally Certified Sustainably Managed Natural Sites.*2
Nationally Certified Sustainably Managed Natural Sites
- 1 A global biodiversity target adopted under the Kunming-Montreal Global Biodiversity Framework, calling for the effective conservation of at least 30% of terrestrial and marine areas as healthy ecosystems by 2030.
- 2 A governmental certification system for areas where biodiversity is conserved through initiatives by companies, organizations, individuals, or local governments. Certified sites—excluding overlaps with designated protected areas such as national parks—are registered in the international OECM (Other Effective area-based Conservation Measures) database.

Responding to Soil and Groundwater Pollution
The Mitsubishi Electric Group conducts environmental assessments in line with legal and regulatory requirements when opportunities arise, such as the sale, purchase, or modification of land. Based on the assessment results, we implement appropriate countermeasures and remediation measures.
Regarding areas that were recognized as having groundwater or soil pollution problems, we are responding appropriately under the guidance of government authorities and conducting groundwater monitoring as necessary.
[Key Activities] In the fiscal year ended March 31, 2026, 22 assessments of soil and groundwater conditions were conducted to confirm that appropriate measures were being taken where contamination was found.
Management of Chemical Substances Used at Business Sites
The Mitsubishi Electric Group has established a "Mitsubishi Electric Group List of Controlled Chemical Substances" based on domestic and international regulatory trends, classifying such chemicals into three proprietary levels. Level I is defined as “substances prohibited to be contained/adhered”; Level II as “substances to be reduced”; and Level III as “substances to be grasped quantitatively,” with clear handling standards established for each classification. In addition, the Mitsubishi Electric Group's domestic production sites manage emissions and transfer volumes of legally designated substances and volatile organic compounds (VOCs) among the Level II "substances to be reduced" and Level III "substances to be grasped quantitatively."
| Environmental Data | Chemical substance emissions |
