Biodiversity Conservation

Basic Approach

Isuzu Group's business activities both depend on the natural world, which nurtures biodiversity, and also have various impacts on it. Therefore, Isuzu Group has developed its Biodiversity Policy, referring to guidelines such as the Ministry of the Environment's Guidelines for Private Sector Engagement in Biodiversity and the Keidanren Declaration for Biodiversity. We are committed to promoting actions that harmonize biodiversity with our business activities to achieve a sustainable society.
To achieve the Aspiration of conserving native biodiversity outlined in the Isuzu Environmental Vision 2050, we will work in collaboration with NGOs and other stakeholders to conserve the native biodiversity in the areas surrounding Isuzu Group operations. Additionally, Isuzu has supported the Keidanren Declaration for Biodiversity since January 2020.

Action Guidelines

  • Each employee learns and has an understanding that our business activities are enabled by biodiversity and at the same time, are affecting it.
  • We engage in activities that reduce our impact on biodiversity and protect it in all of our business activities.
  • We protect biodiversity from a global perspective, taking into account the diversity of local communities.
  • We promote cooperation and collaboration with our stakeholders in order to improve our conservation activities.
  • We contribute to local communities, placing valuing on communication and cooperation with stakeholders through disclosing information on activities and other initiatives.

Initiatives

Assessment of Dependency on and Impact on Nature

Isuzu uses the tool ENCORE*1 to understand the extent of our dependence on and impact on nature. We have assessed these dependencies and impacts throughout our value chain and created a heatmap. Moving forward, we will advance the evaluation of risks and opportunities related to natural capital based on these results and our business operations.

For raw material procurement, we will enhance engagement with our business partners through communication on reducing environmental impact and GHG emissions. For manufacturing and use, we aim to reduce risks and seize opportunities through initiatives aligned with our 2030 Environmental Roadmap.

  2. *2Regarding raw material procurement, since various raw materials (such as petroleum, minerals, glass, natural rubber) and procurement processes (such as chemicals, metals, electronic components, tires) are involved, we take care to adopt those with significant levels of dependency and impact to ensure that we do not underestimate the degree of dependence and impact.

Promoting Biodiversity Conservation Efforts

Isuzu is working on biodiversity conservation activities at its Fujisawa and Tochigi Plants in collaboration with nearby universities.

Since 2013, Isuzu began conducting surveys of the flora and fauna on its plant premises. The results revealed that at both plants, insufficient forest maintenance was causing imbalances in the ecosystem and an overgrowth of invasive species, weakening the public functions of the satoyama (traditional rural landscapes).

Based on advice from the universities, we have been maintaining the plant sites since FY2017, including developing areas where native species can thrive.

Since 2017, annual surveys have confirmed a decrease in invasive species and a trend towards improving the imbalance in the ecosystem.

Promoting Efforts to Protect Local Ecosystems

We promote efforts to protect regional ecosystems in local communities where we conduct business, working to conserve them along with their biodiversity. In addition, by encouraging these activities across the entire Isuzu Group, we will remain committed to protecting global biodiversity.

Watarase-yusuichi Conservation Activities

Since 2016, Isuzu has been involved in conservation activities at the Watarase-yusuichi near its Tochigi Plant.
The Watarase-yusuichi is the largest reservoir area in Japan and is a Ramsar-registered wetland that serves an important flood control function to prevent flood damage in the region. Isuzu, along with volunteers from its Tochigi Plant, nearby Group companies, and their families, participates in activities such as reed cutting, removal of invasive plants, and litter cleanup, organized by local governments and NPOs. The ongoing conservation activities conducted with local residents have borne fruit and storks have been seen flying and nesting in the Watarase-yusuichi.
In FY2022, Isuzu was recognized as an Environmental Conservation Organization by Tochigi City. Additionally, for three consecutive years, in FY2022, FY2023, and FY2024, Isuzu received letters of appreciation from Oyama City as a Watarase-yusuichi Conservation Support Organization.
Furthermore, the Tochigi Plant is involved in tree planting activities in Ashio, located upstream along the Watarase River, which flows into the Watarase-yusuichi. Ashio was once devastated by smoke pollution from copper smelting, leading to the deforestation of the surrounding mountains. By participating in reforestation efforts, Isuzu aims to create opportunities for learning about environmental conservation through activities both upstream and downstream.

Participating in Activities to Develop Forests That Supply Water in Kanagawa Prefecture

Since FY2019, the Isuzu Fujisawa Plant has been participating in Kanagawa Prefecture's Forest Restoration Partner project, conducting conservation activities to protect the forests in the Ashigarakami District that serve as the water source for the groundwater used by the plant.

Since FY2020, Group companies within the Fujisawa Plant have also joined these efforts. Through thinning work to restore neglected forests to a healthy state and nature observation activities, participants are reminded of the importance of biodiversity and the significance of preserving the forests that serve as water sources.

Although activities were suspended in FY2021 and FY2022 to prevent the spread of COVID-19, they resumed in FY2023. In November 2023, 18 employees and their families from two companies participated in the conservation activities.

Isuzu Plaza's Biotope

At Isuzu Plaza, a biotope has been established to replicate the unique ecosystem of the Fujisawa region, where the plaza is located. Since FY2020, we have been collaborating with local university research labs. Our efforts include improvements like revising tree signage content to create a biotope that serves as a place of relaxation for the community, allowing everyone to feel closer to nature. We are actively seeking various pieces of advice to achieve this goal.
We encourage students to utilize this space for fieldwork and as a practical platform for considering community coexistence. We also provide them with opportunities to present their research findings to Isuzu. Additionally, employees are discovering the significance of ecosystem conservation afresh, while drawing inspiration from the innovative ideas of the students.

Promoting Sustainable Procurement

Adoption of Environmentally Friendly Materials

Isuzu has replaced traditional wood used for truck beds with bamboo, a member of the grass family, in consideration of forest conservation.
Bamboo, with its fast growth rate that allows it to be used as a material in about five years, along with its excellent durability, is considered a suitable material for truck beds.
Bamboo flooring material is being used in many vehicle models, including the new ELF released in March 2023.

Developing Human Resources to Build a Society in Harmony with Nature

Isuzu has been conducting regular environmental education for employees since FY2017 to raise environmental awareness and deepen understanding of Isuzu's environmental activities.
This education is provided through a combination of e-learning and in-person training, which also helps reduce CO2 emissions associated with employee travel.

Starting in FY2024, Isuzu introduced common environmental education for executives and personnel responsible for environmental activities across the entire Isuzu Group. This initiative aims to enhance understanding of the Isuzu Environmental Vision 2050 and the 2030 Environmental Roadmap. This activity will be expanded to all Isuzu Group employees in the future, facilitating human resource development so that each member of the Isuzu Group can contribute to the realization of the Isuzu Environmental Vision 2050 alongside our customers and partners.

Communication with the Local Community Surrounding the Plant

At the Isuzu Fujisawa Plant, we provide an opportunity for members of local residents' associations from six neighboring areas to learn about Isuzu's and the Fujisawa Plant's environmental conservation initiatives.
In October 2019, 46 participants attended the event.
