Specific Environmental Initiatives

Based on our Environmental Philosophy and Policy, we have set mid-term environmental goals to achieve by 2025 for three issues: decarbonized society, resource recycling, and harmony with nature. We are pursuing specific initiatives to achieve these goals. Countermeasures against climate change are globally important tasks, and we need to take long-term initiatives. We are taking action with the aim of achieving carbon neutrality by 2050.

* The Environmental Philosophy shows the goals of our Human resources development environmental activities while the preface of the Environ-mental Policy shows the direction of such activities. The six items of Environmental Policy show the prerequisites for achieving the goals, three mid-term environmental goals, and the factors for achieving them, which are reflected in the Foster Group’s environmental management system.

Mid-Term Environmental Goals 2025

To achieve the mid-term environmental goals 2025 that we set in 2020, we continue activities to reduce the environmental load from a lifecycle perspective, by working together with manufacturing sites.

Environment Management System and ISO 14001 Certification

We have obtained ISO 14001 certification at headquarters and all overseas manufacturing sites and embody the Foster Group’s Environmental Philosophy and mid-term environmental goals. At headquarters, we monitor the activities conducted at each site and check their results. We have expanded the scope of application to the Head Office of Foster Electric (1-1-109 Tsutsujigaoka, Akishima City, Tokyo) and its Shizuoka Office (6-12-2 Toro, Suruga Ward, Shizuoka City, Shizuoka) while maintaining the environment management system. We present the ISO 14001 certification at the request of stakeholders.

Environmental Activities

CO2 Reduction (Scope 1, 2)

The Foster Group’s absolute CO2 emissions in fiscal 2022 were 14% less than the previous fiscal year and 42% below the fiscal 2018 level, partly reflecting restrictions on production activities amid the COVID-19 pandemic. For Scope 3 emissions, the data can be found in the Data Table at the non-financial data of the Integrated Report 2023.

Activities to Preserve Biodiversity

We have set “Biodiversity conservation” as one of the tasks for “Harmony with nature,” a mid-term environmental goal, and continue to hold lecture meetings and training on biodiversity, sessions for observing the immediate natural environment, and neighborhood cleanup activities. This fiscal year, we began to prepare for information collection and other initiatives for disclosing information based on the recommendations of the Task Force on Nature-related Financial Disclosures (TNFD).

Water Risk Management

Each site manages water withdrawal and discharge by setting their standards based on local laws and regulations. The headquarters uses “AQUEDUCT”, a water risk assessment tool of the World Resources Institute (WRI), to understand the local water risks at each site. Since 2020, we have been addressing water risks by including “Reduce water consumption” in the mid-term environmental plan.

Chemical Substance Management

The Group has set forth its autonomous management standard, which reflects the applicable laws and regulations of countries, including the RoHS Directive and REACH regulations, and customers’ requests for handling environmentally hazardous substances contained in its products to minimize their impact on the environment. We eliminate any controlled substances from our products via eco-friendly procurement and management of necessary parts and/or materials purchased. Based on the aforementioned scheme, we have established an optimum management system for the efficient search and collection of information about chemical substances that are contained in parts and materials and precise communication of information necessary in the supply chain.
In addition, to ensure communications of related information, we provide our suppliers with briefing meetings every year primarily at our overseas sites.

Environmental Consideration at Headquarters

Our headquarters employs environmental load reduction technologies such as lighting control by daytime sunlight, air conditioning by outside air, ice thermal storage air conditioning system, and doubleskin facade. Electricity consumption is controlled further by limiting maximum power consumption during the day, promoting Cool Biz and Warm Biz campaigns, turning off all the lights in the building for lunch breaks, having employees work from home in response to the COVID-19 pandemic, and promoting the replacement of all of the lights in building with LEDs. The headquarters strongly promotes active participation in climate control measures by procuring clean energy prior to the other sites in the Group. In addition, as part of our ESG activities, we have ended the use of disposable plastics and paper cups and use reusable cups for the beverages sold in the cafeteria. Further, when renovating the tea server, we introduced a product that uses an environmentally friendly refrigerant.

Initiatives to Achieve Zero Waste Emissions

At headquarters, we are engaged in the recycling of waste and other materials through thorough activities to raise awareness of the sorting and separation of regular waste, plastics, and industrial waste. We have selected a new recycling service provider and continue our activities aiming to achieve zero waste emissions by continuing to raise awareness of recycling and promoting the recycling of waste from our business activities into raw materials.

Recycled materials being carried out

Environmentally Friendly Products


We are accelerating moves to develop basic technologies for next-generation speakers for eco-friendly vehicles and to introduce such technologies to commercial products.

■Development of lightweight speakers

We are developing on our own and productizing speakers incorporating technologies enabling lighter weight, by taking measures including optimization of resin and metal components, which are made with optimization design using CAE analysis, and studies of carbon fiber reinforced thermoplastics (CFRTP) as a new material. At present, we continue to develop element technologies for lightweight speakers, aiming to reduce the weight of 6.5” lightweight speaker, which is approx. 200 g, to 100 g or less by 2025.

■VOC reduction

As initiatives to reduce the volume of VOCs remaining at production sites and in the passenger cabins of vehicles, we have cut the use of organic solvent adhesives for bonding parts and drive the development and adoption for commercial products of an adhesive with a reduced solvent content. We are also committed to the development of bonding methods which do not use adhesives, such as ultrasonic welding.

■Reduction of CO2 emissions

We are undertaking design development activities for reducing power consumed in manufacturing speakers to cut CO2 emissions. We are making development efforts to achieve the medium-term CO2 emissions reduction target, by improving and changing methods of bonding parts and by reducing the use of a drying furnace in stages.

*We will continue development and introduction with a target of achieving 30% as the ratio (to sales) of commercialized car speakers incorporating these environmental technologies.
2022 result: 16%
2025 target: 20% or higher
2030 target: 30% or higher

Speakers developed with weight reduction technologies


We proactively apply environmentally friendly design to haptic vibration actuator devices, which are a part of new user interfaces for CASE*, VR, AR, and other technologies. In consideration of VOC emissions, we have adopted adhesives that do not contain harmful solvents. To reduce the labor necessary to manufacture products, we have realized quick curing using UV radiation and pulse heat soldering. In addition, to reduce solder consumption, we have developed resistance welding and put it to practical use. We will maintain our status of using adhesives that 100% do not contain harmful solvents.
* CASE: Connected, Autonomous, Shared, Electric

Headphones and Headsets

We have been active in incorporating environmental considerations in our product and/ or process design. In reducing environmentally hazardous substances in our products, we address the most up-to-date information regarding countryspecific legal requirements and the RoHS2, and propose to our customers. As a way of reducing waste volume, we have also been keen on minimizing waste materials, reusing raw materials by introducing new equipment, and developing products made of natural materials. For products with electronic circuits, we have adopted power-saving parts in our efforts to develop products with low power consumption.
For microspeakers used for headphones or headsets, we are working towards environmentally friendly product manufacturing by introducing adhesives that do not contain toluene for new microspeakers in order to reduce VOC (replacing the parts that use solvent adhesives). For microspeakers used for headphones or headsets, we are working towards environmentally friendly manufacturing by introducing toluene-free adhesives for new microspeaker products in order to reduce VOC (Replacing the parts containing solvent adhesives).

  • Development target and result for toluene-free products
    ・Target for 2024: The ratio of products that do not contain toluene to be 100%.
    ・FY2022 Result: The ratio of products using toluene-free adhesives: 78%
  • Plans for achieving targets
    ・Make confirmations based on requirements on the use of toluene in the development and design stage.
    ・Continue to study alternative adhesives to achieve 100% as the ratio of products using toluene-free adhesives.

Example: Environmentally friendly microspeaker
(microspeaker with a 35 mm diameter for headphones)

Example: Product developed by using power-saving parts(Bluetooth wireless earphones)

Environment Month Activities (Headquarters)

Environment Lecture Presentation

We invited an outside expert to speak on decarbonization management leading to corporate value to our officers, department heads, and group leaders (in the form of a Web conference). The lecture served as an opportunity to think about issues that we should address.

Other activities

We solicited photos of the immediate natural environment provided an environmentally friendly lunch menu, and participated in nature observation sessions, and thus we created catalysts for being in close contact with the immediate natural environment and thinking about environmental initiatives from different positions.

Headquarters: Akishima City Cleanup Movement (Mini-Clean Activities)

Despite the many times these activities have been postponed or cancelled and the many employees working from home due to the COVID-19 pandemic, the annual number of participants increased by as much as 22.1% from the previous fiscal year, to 138 (participation rate: 25.1%). The total weight of waste increased to 15.1 kg. In addition, junior high school students were able to participate in the activities through a work experience program. This fiscal year, we will also participate in the city cleanup movement of Akishima City.

Information Disclosure Based on the TCFD Recommendations

Believing in the importance of topics related to the environment and climate change, we declared our support for the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD*) in February 2022. At the same time, we joined the TCFD Consortium, where member companies, financial institutions, and other entities discuss effective information disclosure and appropriate initiatives following the TCFD recommendations.

*Task Force on Climate-related Financial Disclosures: This task force was established in 2015 by the Financial Stability Board (FSB), which comprises central banks, financial authorities, and international organizations from all over the world. It is aimed at considering how to estimate the impact of climate change on business management and how to disclose such information. It recommends that companies and other entities disclose information about climate change-related risks and opportunities.

We will identify our climate change-related risks and opportunities and then continue to drive effective measures by leveraging internal and external knowledge. At the same time, we will disclose information proactively by following the TCFD recommendations.


Viewing sustainability as an important theme, we announced our ESG Management Statement and set goals of achieving "a decarbonized society" and "zero emissions in 2050" as part of our materiality (priority issues) in March 2021. These goals and reduction activities have been shared by all employees and are being driven by them.
We have set up the Sustainability Committee (which meets every month), chaired by the president, for the purpose of driving ESG management. This committee meets with the attendance of the sustainability officer, heads of divisions, and persons responsible for the promotion of sustainability activities appointed by departments of the headquarters and overseas bases. It identifies climate change-related issues, deliberates on and determines related policies and measures, and shares and monitors their progress.
The Board of Directors deliberates on and makes decisions on announcements of support and information disclosure related to TCFD concerning management issues, as well as reduction targets, measures, and other matters. It also receives reports on deliberations and progress made by the committee, regularly and as needed, thus supervising the committee’s execution of operations.


Under the framework advocated in the TCFD recommendations, we considered changes in the external environment in 2030 and analyzed the impact of climate change on us.
We adopted the 1.5-degree and 4-degree scenarios for analyzing risks and opportunities. Regarding transition risks, we consider how policies and markets will change for the alleviation of climate change. Concerning physical risks, we also analyzed how the frequency and impact of climate changerelat-ed weather disasters will change.
We reflected the identified risks and opportunities in the medium-term business plan. Moving forward, we will also consider the financial impact on the Company. We are conducting an analysis of part of the automotive business, which is subject to a significant impact. We will continue the analysis by focusing on other businesses as well.

3.Risk Management

We have established the Risk and Crisis Management Committee, which is chaired by the president, to ensure that risks which may affect business management are addressed promptly and appropriately. This committee evaluates and manages company wide risks and devises and implements measures to address them.
Especially, climate change-related risks are positioned among the top risks in the committee's total risk assessment. The Sustainability Committee identifies and evaluates such risks, implements measures to tackle them, and takes other initiatives to improve the effectiveness of risk management. Information about the statuses of risk management and measures is also shared with the Board of Directors, which supervises and monitors risk and crisis management of the overall company and tries to ensure consistency between risk management and materiality analysis, thus enhancing the total risk management in the entire company.

4.Metrics and Targets

Toward the achievement of sustainability, we have established the Foster Group ESG Management Statement, under which we aim for "Decarbonized Society" and "tireless efforts to achieve Zero Emissions" in the medium and long run. Under this Statement, we have revised our mid-term environmental goals for 2030 (Scope 1, 2) in line with the 1.5-degree goal of the Paris Agreement. We have also set a new long-term goal for 2050.

1. Mid-Term Reduction Goals for 2030

・Scope1、2:Reduce absolute CO2 emissions 50% by 2030 from a 2018 base-year
・Scope3:Reduce absolute CO2 emissions 15% by 2030 from a 2018 base-year

2. Long-Term Reduction Goal for 2050

・Aim to achieve carbon neutrality by 2050
To achieve this goal, we have developed the CO2 Reduction Action Program [Ver. 2023]. The head-quarters and the other sites will work together in accelerating CO2 reduction activities in a group-wide manner.
