Natural symbiotic action

Basic Stance

If each of DENSO’s nearly 170,000 employees around the world act with careful consideration for nature, we would be able to make a significant contribution toward the resolution of today’s environmental problems. We recommend eco-friendly manufacturing within our business activities and engage in environmental conservation activities in local communities as a corporate citizen.
Furthermore, under the seventh phase of the Environmental Action Plan, we are reinforcing activities that contribute to biodiversity in order to deepen our understanding of the dangers facing biodiversity and promote conservation initiatives.

Specific Initiatives

(1) Promoting Activities That Contribute to the Global Environment

Each of our business sites around the world promote activities that contribute to the environment, such as tree-planting and regional beautification activities. During the sixth phase of the Environmental Action Plan, participation in these activities grew to include 143 companies, accounting for roughly 90% of the entire DENSO Group. Going forward, we will continue to proactively promote activities that contribute to the environment.

  • Global Environmental Event Promotion

(2) Reinforcing Activities That Contribute to Biodiversity

Under the seventh phase of the Environmental Action Plan, we are focusing our attention on activities such as water area conservation, forest and woodland conservation, and tree planting and tree raising. This section provides examples of activities we are pursuing in each country and region to resolve biodiversity-related issues.

1. Water Conservation Activities

With the participation of our employees and in collaboration with local communities, we are engaging in activities to preserve the biodiversity of water areas near company offices and of major water areas in each country and region of operation.

For example, at the Toyohashi Plant of DENSO CORPORATION, we have been partnering with the NPO Omotehama Network since 2007 to promote environmental conservation activities along the Omotehama coast, an egg-laying area for loggerhead turtles, which are an endangered species.

In addition, at our business sites across the globe, we are pursuing environmental conservation and beautification activities for water areas inhabited by wildlife.

2. Forest and Woodland Conservation Activities

In Japan, a country with an abundance of forests, preserving healthy forests and woodlands is an essential part in maintaining biodiversity. To that end, a large number of DENSO employees participate earnestly in forest and woodland conservation activities together with local community members.

“Water Resource Forestation Project ” (DENSO UNITY SERVICE CORPORATION)
At DENSO UNITY SERVICE CORPORATION, we have been promoting the “Water Resource Forestation Project” every year since 2005 in the Asuke District of Toyota City, an area that provides vital water resources for Aichi Prefecture. Through this project, we not only conduct tree-thinning and tree-planting activities but also create nature hiking and handicraft courses that people can enjoy with their families. In these ways, we are engaging in forest


The DENSO Green Project

With the aim of restoring biodiverse ecosystems and conserving forests, local communities have been working together with DENSO employees, their families, and NPOs since 2006 to promote the DENSO Green Project, which includes tree-thinning activities and events to experience nature.
By June 2022, we had held 57 events and activities attended by 8,987 volunteers, including local residents, employees of DENSO CORPORATION and domestic Group companies, and their families.

3. Tree-Planting and Tree-Raising Activities

The destruction of forests is a significant global issue, and we are therefore making worldwide efforts to restore forests in order to protect biodiversity.

We have been participating in tree-planting activities in numerous countries around the world, including Germany, the United Kingdom, and Italy in Europe; Brazil in South America; and Singapore, Thailand, Malaysia, the Philippines, India, and South Korea in Asia. For example, at DNPH in the Philippines, we took part in the “Mount Making Tree Planting” project, in which we conducted tree-planting activities while reviewing documents to confirm the progress of tree growth and recording important growth milestones. In Thailand and Malaysia, a large number of DENSO employees have participated in tree-planting activities to protect mangrove forests along coastlines.

(3) All Toyota Biodiversity Preservation Activity

In cooperation with Toyota Group companies, DENSO is participating in the Green Wave Project, an activity for preserving biodiversity. We are working to expand a circle of activities that currently include cultivating forests and preserving wildlife within factory areas to involve the local community and administrative bodies.

Topic: DENSO Joins the 30 by 30 Alliance for Biodiversity

DENSO endorses the “30 by 30” initiative and has joined the 30 by 30 Alliance for Biodiversity.
30 by 30 is a target to effectively conserve at least 30 percent of the planet’s land and ocean to curb biodiversity loss and restore healthy ecosystems by 2030. Since 2006, DENSO has been actively carrying out greening activities not only on the premises of the Company’s business sites but also in the surrounding areas and in fields around expressways where automobiles are used, as well as conducting training to improve employees’ environmental awareness centered on the theme of conserving biodiversity.
We will continue to contribute to the development of a sustainable society through our participation in the 30 by 30 Alliance for Biodiversity and by leveraging the years of experience and knowledge we have cultivated in promoting biodiversity conservation.
