Environmental Management

Environmental supply chain

Toyobo is engaged in green procurement and green purchasing with the aim of maintaining and strengthening our environmental activities.

Promoting green procurement and green purchasing

We prioritize procurement of raw materials with a low environmental impact, and work with business partners who take a proactive approach to protecting the environment. Together, we are promoting green procurement to help build a sustainable society. We ask our business partners to provide information about the chemical substances contained in products, as follows.

(1) That the material does not contain any of the prohibited substances specified by Toyobo.

(2) That the content of hazardous substances specified by Toyobo has been identified.

In fiscal 2019, we revised our “Chemical Content Information Sheet” based on the information sharing scheme “chemSHERPA®,” developed by Japan’s Ministry of Economy, Trade and Industry, and requested that our business partners respond. In October 2020, we revised our "CSR Procurement Guidelines."

In fiscal 2022, we plan to again revise the "Chemical Content Information Sheet" based on revisions to laws and regulations, and request that our business partners respond. For general purchased goods, we are promoting green purchasing with the use of environmental labels.

Environmental compliance

The Toyobo Group is committed to reducing emissions by not only complying with legal and regulatory standards, but by also making continuous improvements in the prevention of air and water pollution. We will continue to further reduce our environmental impact.

For fiscal 2019 to 2021, there were no environmental-related fines or penalties.

Safety and environment assessment

In order to improve the safety and environment levels of the Toyobo Group, the Safety and Disaster Management Promotion Committee and Global Environment Promotion Committee conduct safety and environment assessments in accordance with company regulations. As well as carrying out annual self-evaluations based on a checklist, we conduct on-site audits of each of our locations once every three years in order to maintain and improve management levels.

In fiscal 2021, we are planning to conduct on-site audits at two Toyobo business sites and eights Group companies. However, due to the spread of new coronavirus infections (COVID-19), we carried out the audits at one business site and three group companies. The audit results showed that all of these sites and companies performed well in terms of safety and environmental management.

Locations at which Audits Have Been Performed in the Last Three Years

There were no environmental-related accidents in fiscal 2019 to 2021.

Environmental education

The Toyobo Group promotes a variety of educational and awareness activities in order to improve the environmental awareness of the employees.

During Environment Month, we hold an annual environmental seminar with outside lecturers invited, in which many employees participate. In addition, at each business site, we hold environmental exhibitions featuring panels that introduce our group's environmental activities as well as exhibitions of eco-conscious products, and these introduce the Toyobo Group's environmental activities to our employees and the local community.

In addition, we are promoting environmental education through a unique curriculum tailored for new employees.

Environmental seminars

In fiscal 2022, due to the spred of COVID-19, we held environmental seminars, connecting the lecturer and audience online. 294 employees attended the seminars, where they lively exchanged questions and answers despite being held through a screen.

Up until fiscal 2020, the environmental exhibition had been held every year, but was canceled for fiscal 2021 in light of the spread of COVID-19.

In 2022, the environmental exhibition was changed to held in parallel with the web.

Environmental education on joining the company

Education upon joining the company is provided not only to fresh hires, but also to mid-career employees at all locations, including at Group companies, and the number of participants in fiscal 2021 reached 559. In addition to explaining plans and achievements regarding the global environmental conservation system and initiatives, the training helps participants understand why environmental protection is important by linking it with the Toyobo Group Charter of Corporate Behavior, and explains what is expected of employees of the Toyobo Group.

Eco-conscious products

Mechanism for certification of eco-conscious products

As clearly stated in the Toyobo Group’s Charter of Corporate Behavior, the Toyobo Group strives to save energy as well as reduce and re-use resources. We also develop products and technologies that help mitigate our impact on the environment. These products and technologies are defined and evaluated under our Eco-Review system. This system evaluates the following aspects at every stage in the product life cycle: “climate change prevention,” “reduction of chemical substances,” “resource conservation,” “reduction in waste,” and “other environmental contributions”. Products that meet these standards are certified as ECO-PARTNER SYSTEM® products. Since the Eco-Review is carried out at every product life cycle—from R&D to commercialization—issues that require improvement from an environmental protection perspective are identified and improved at an early R&D stage prior to the subsequent review. Consequently, we are contributing to the environment as we develop our products and technologies.

Eco-review Evaluation Items

Review and Certification Process

Ratio of ECO-PARTNER SYSTEM® product sales increases to 29.9% (FY2021)


Our goal is to increase the ratio of ECO-PARTNER SYSTEM® product sales to 30% of total sales by fiscal 2031 (the ratio was 25% until fiscal 2016). In fiscal 2020, the ratio was 30.4% (sales of 60.6 billion yen), achieving the target. Accordingly, we have set new targets of 40% by fiscal 2031 and 60% by fiscal 2051. We will continue to create eco-conscious products.

In addition, we are considering expanding the applicable range of the certification system to Group companies, and have begun to identify issues in order to calculate the sales ratio of ECO-PARTNER SYSTEM® products for the entire Group.
