Basic Concept

Biodiversity on earth is supported by a healthy environment including the atmosphere, water, and soil, and the environmental impact accompanying business activities affects this balance. In particular, due to advancing industrialization especially in emerging nations, reducing regional environmental impact and consideration for ecosystems have become increasingly important.
Suzuki recognizes the Biodiversity conservation as one of its significant management issues. Guided by the Philosophy of Conduct, “Sho-Sho-Kei-Tan-Bi (Smaller, Fewer, Lighter, Shorter, Beauty),” we promote efficient manufacturing that minimizes the use of resources and energy. Through this approach, we reduce the environmental impact from development to production and use of our products, and strive to minimize our impact on ecosystems. We also contribute to local environmental conservation through reduced exhaust gas emissions in products and reduced environmental impact in production processes.
Furthermore, by collaborating with stakeholders including our suppliers and local communities and promoting business activities that are in harmony with the natural environment, we are committed to conserving biodiversity and realizing a sustainable society.

Efforts for Biodiversity

Suzuki introduced the environmental brandto realize the philosophy of the Suzuki Global Environment Charter and announced the Suzuki Biodiversity Guidelines as the environmental policy within the brand.
The Suzuki Biodiversity Guidelines will be our guiding principles for recognizing that business activities, etc., can impact biodiversity, which has provided human society with enormous natural blessings (ecosystem services) since the birth of humanity, for reducing such impacts, and for making efforts to ensure sustainable usage.
Suzuki has taken many actions to reduce impacts on biodiversity in its business and social contribution activities and endorses the Keidanren Initiative for Biodiversity Conservation.
By releasing the Guidelines, we aim to raise awareness of biodiversity throughout the entire Suzuki Group, and to develop a sustainable society that can coexist with nature, while keeping good relations with our business partners and local communities.

Specific actions

Environments and ecosystems of surrounding areas

In 2018 and 2020, we conducted surveys of water bodies where effluent discharged from our five domestic sites accounts for more than 5% of the annual average river flow volume, as well as the flora and fauna inhabiting those water bodies. As a result, we identified 213 species of flora and fauna, including 12 endangered species.

Wastewater discharge destinations and water areas impacted

• *1 Water areas where discharge from Suzuki accounts for 5% or more of the average annual water volume of rivers
• *2 Species that are listed as endangered on the red lists of the International Union for Conservation of Nature and Natural Resources and the Ministry of the Environment, as well as red lists and regulations of prefectures and cities.

Forest conservation activities

Suzuki’s Forest (Hamamatsu)

Suzuki concluded a Volunteer Forest agreement with the Tenryu Forest Administration Department of the Forestry Agency and started forestry preservation activities in March 2006 at Suzuki’s Forest located in Inasa-cho, Hamana-ku, Hamamatsu. Our employees and their families conduct forestry activities every year, such as planting trees, clearing away the undergrowth, and shiitake mushroom inoculation activities.
A total of 37 activities have been conducted (19 planting sessions and 18 undergrowth clearing sessions) and attended by approximately 1,700 volunteers in total.

Forest of the Suzuki Shimokawa Proving Grounds (Hokkaido)

The Suzuki Shimokawa Proving Grounds are located in the town of Shimokawa, Kamikawa County, in northern Hokkaido, where forests cover approximately 90% of the total land area. Shimokawa Town became the first municipality in Hokkaido to obtain international FSC_® certification (Shimokawa Forest Owners’ Cooperative, Shimokawa Town, and Northern Kamikawa Forest Management Office; FSC_®C015134) in 2003. In 2011, the town was designated by the Japanese government as an “Environmental Future City” model municipality that leverages its abundant forest resources for community development, with the goal of becoming a “Forest Future City Where People Thrive.”A forest of approximately 300 hectares located on the proving grounds was also recognized as satisfying the strict forest stewardship standards of the FSC_® certification program, so the area was also registered on the FSC_® Forest Group Certificate for Shimokawa Town in 2006 (FSC_®C015134). Furthermore, Suzuki will continue to promote co-existence and co-prosperity with local communities, which take great care of nature, through participation in events and sales of agricultural products.

Participation in the Corporate Forest Program (Hokkaido)

As part of its environmental preservation and social action programs, Suzuki endorses the purpose of the Corporate Forest Preservation Program^*, which utilizes national forests. We have been supporting forest development activities through a Profit-Sharing Silviculture Agreement concluded with the Japanese government (Forestry Agency) for the period from 1996 to 2028. For an approximately 4.3 hectare national forest (containing approximately 3,000 trees) in Shimokawa Town, Suzuki conducts profit-sharing afforestation by entrusting the work to the local forestry cooperative through the Hokkaido Regional Forest Office. Also, for many years, we have contributed to the preservation of national land through watershed conservation, prevention of soil erosion and CO₂ absorption and fixation, and when revenue is shared, the net profits will be used for further afforestation activities.

Suzuki Clean Ocean Project

Implementation of the Suzuki Clean Ocean Project

The Suzuki Clean Ocean Project is Suzuki’s environmental initiative comprising three activities: 1. the CLEAN-UP THE WORLD CAMPAIGN (waterside cleanup activities), which has continued since 2011; 2. activities to reduce the use of plastics in packaging for outboard motors and service parts, launched in 2020; and 3. activities to collect marine microplastics using the Micro-Plastic Collecting Device for outboard motors. This project is a concrete Suzuki initiative aimed at addressing the social issues identified in the Sustainable Development Goals (SDGs), and it reflects Suzuki Marine’s commitment to pursuing its brand slogan, “THE ULTIMATE OUTBOARD MOTOR,” from an environmental perspective as well. Through these three activities, Suzuki will join forces with partners around the world, including outboard motor users, dealers, boat builders, business partners, Suzuki Group companies, employees, and their families, to clean up oceans worldwide.
As our activities are also aligned with the objectives of the Plastics Smart campaign promoted by Japan’s Ministry of the Environment, we registered the project with the campaign in 2018. Details of Suzuki’s initiatives are also featured on the Ministry’s website.

Clean-Up the World Campaign (waterside cleanup activities)

Suzuki’s waterside cleanup activities marked their 17th year in 2026. The activities began in Japan in 2010 and have been carried out globally by the Suzuki Group under the name CLEAN-UP THE WORLD CAMPAIGN since 2011. In FY2025, simultaneous cleanup activities were held worldwide on July 12, with more than 2,800 people from 34 countries and regions participating in community contribution activities through waterside cleanups.
The cumulative number of participants since the activities began reached 28,000 in FY2025, and the activities continue to expand each year.

Marine microplastic collection activities using Suzuki’s Micro-Plastic Collecting Device for outboard motors

In addition to its conventional waterside cleanup activities, Suzuki has launched an initiative to collect marine microplastics floating in the ocean. This initiative uses the Micro-Plastic Collecting Device for outboard motors developed by Suzuki to collect microplastics near the water surface. The device has been installed as standard equipment on certain outboard motor models produced since July 2022 and is sold worldwide.
In FY2025, Suzuki also made 34 patents related to the Micro-Plastic Collecting Device available royalty-free. This marked the first time Suzuki had made any of its patents available royalty-free.
By making these patents available, Suzuki aims to further accelerate efforts to improve the marine environment together with companies and organizations in Japan and overseas that share the same concern.

Cleanup activities

Suzuki Manner Improvement Activities

Suzuki was registered in the “Hamamatsu City Road/River Foster-parent System”^* in September 2004, and has been conducting cleanup activities under the banner of “Suzuki Manner Improvement Activities,” with the aim of improving the manners and environment/beautification awareness of employees. For those activities, in-house volunteers clean roads around the head office and the Takatsuka underpath every month. A total of over 18,400 participants have conducted the cleanup activities 255 times through March 2026, and they have collected 115 mini-truck loads of flammable and non-flammable garbage. In 2023, this activity was acknowledged by the government with the Company receiving the Minister of Land, Infrastructure, Transport and Tourism Award for FY2023 as a stewardship organization for rivers, coasts, and roads.

* Groups that hope to be “foster parents” decide their cleanup areas and what kinds of activities they will carry out, report them to the Mayor, and conduct cleaning of roads and related activities

Efforts in product use

LCA (Life Cycle Assessment) ^*1method based calculation of product air pollution emissions

Suzuki conducts LCA not only on CO₂ but on other air-polluting substances as well.
For the current XBEE (Mild Hybrid vehicle), we have been able to reduce NOx, SOx, PM, and NMHC^*2throughout its lifecycle compared to the previous model.
Suzuki will also continue its initiatives to reduce such substances other than CO₂.

*1 Life Cycle Assessment. A method of evaluating a product as a whole by calculating its potential environmental impact at each stage of its life cycle, from raw material processing to disposal. Evaluation results are displayed as an index to confirm the relative environmental improvement effect.
*2 NMHC: Non Methane Hydrocarbons. A collective term for volatile organic compounds (VOCs) among hydrocarbons present in the atmosphere, excluding methane, which undergoes almost no photochemical reactions.

Design and development efforts

Efforts in reducing emission gas

(Automobiles) Reducing exhaust gas emissions

As part of our multi-pathway initiatives, we are focusing on improving engine combustion technology and exhaust gas purification performance, which will contribute to reducing environmental impacts and the use of precious metals in catalysts.
The new Swift, Solio, and XBEE are equipped with the newly developed Z12E engine. The Z12E has achieved world-class high-speed combustion through improvements to the engine itself. By combining this with a highly efficient catalyst and GPF (soot collection filter), we have achieved clean exhaust gas performance while maintaining output performance.
In 2026, Maruti Suzuki India Limited released the “Wagon R FFV,” Suzuki’s first flex-fuel automobile. Flex-fuel vehicles can run on any mixture of ethanol and gasoline. From an environmental perspective, they help reduce particulate matter (PM) emissions in exhaust gases, thereby contributing to the improvement of local air quality.

(Motorcycles) Reducing exhaust gas emissions

We are advancing efforts to further reduce exhaust gas emissions by complying with the Euro5 standards and the 2020 domestic emission gas regulations.
The new scooter Address 125 has, among other components, optimized the catalyst, cam profile, injector, and intake pipes to comply with the latest exhaust gas regulations.

(Outboard motors) Reducing exhaust gas emissions

Suzuki’s four-stroke outboard motors comply with the 2008 emission gas regulations set by the California Air Resources Board (CARB), the secondary emission gas regulations set by the U.S. Environmental Protection Agency (EPA), the emission gas regulations under the Recreational Craft Directive (RCD II: Directive 2013/53/EU) in Europe, as well as the 2011 marine engine emission voluntary regulations (secondary regulation) set by the Japan Marine Industry Association.

Efforts to reduce chemical substances

Reducing VOCs (Volatile Organic Compounds)^*1 in cabins

In order to provide safe and secure products to customers, we are making efforts to reduce cabin VOCs by using materials, bonding agents, etc. that emit less VOCs for automobile interior parts. We have achieved the Japan Automobile Manufacturers Association target*2 for in-cabin VOC concentrations for all new automobiles sold in Japan, and even for vehicles produced overseas, and in FY2025 we achieved this target for new models such as the e-VITARA. We are also getting ready to address new regulations that are being considered in Europe for the future.
In addition, we are making efforts to reduce odors from interior parts and cabin odors to promote a more comfortable cabin environment.

• *1 VOCs are deemed to be a cause of sick building syndrome (bringing about a headache and/or sore throat) and have been gaining attention for their impact on health.
• *2 The Japan Automobile Manufacturers Association (JAMA) has been making voluntary efforts with new passenger car models sold from April 2007 and new commercial vehicle models sold from April 2008 to satisfy the guideline values for vehicle cabin VOCs for substances defined by Japan’s Ministry of Health, Labour and Welfare.

Efforts in reducing noise

(motorcycles) Product example

DR-Z4SM features many noise-reducing structures to meet the latest noise regulations, and is designed to minimize any increased weight.

• (1) The air cleaner has sufficient capacity and reduces intake noise; ribs configured on the inner walls of both side cases increase rigidity to reduce radiated sound from wall surfaces.

• (2) The muffler has sufficient capacity and a structure with a high sound-silencing effect. By configuring glass wool on the inner wall, we improved damping performance and reduced radiated sound from wall surfaces.

• (3) The clutch cover has reinforcing ribs optimized using CAE which have been incorporated into the inner wall to increase rigidity and reduce noise radiation from the wall surface.

Initiatives in the Development of the Micro-Plastic Collecting (MPC) device

The MPC developed by Suzuki is a device that can collect microplastics that form in the natural environment when plastics that are not properly collected enter the ocean and break down into microplastics. Starting in July 2022, we began installing MPC as standard equipment on five models: DF140B, DF140BG, DF115B, DF115BG, and DF100C.
Since improving the accuracy and efficiency of sorting and analyzing recovered plastics is one of the challenges facing MPCs, we are conducting research in collaboration with the Nakamura Laboratory of the Faculty of Agriculture, Shizuoka University to develop a technology for distinguishing microplastics by utilizing the adsorption properties of proteins onto plastics.
In addition, Suzuki began offering royalty-free licenses for patents related to the MPC in March 2026. We will continue to further expand initiatives for marine environmental conservation through the Suzuki Clean Ocean Project.

Promotion of green procurement

We established the Suzuki Green Procurement Guideline in September 2003 that indicates our basic policy to purchase components and raw materials with low environmental impact from suppliers who are actively engaged in environmental conservation activities. In addition, we ask suppliers to submit the Suzuki Green Procurement Promotion Agreement to us as proof of their agreement to our guideline.
Furthermore, in April 2026, we revised our guidelines and adopted the Self-Assessment Sheet, an industry-standard tool developed by the Japan Automobile Manufacturers Association and the Japan Auto Parts Industries Association, to replace our previous self-assessment checklist. Through this change, we are enhancing consistency with industry-wide initiatives while requesting suppliers to submit this form.
More than 91% of suppliers of mass produced parts have obtained external certifications including ISO 14001. Also, we are committed to ensuring proper compliance not only with existing regulations, such as the European ELV Directive and European Regulation concerning the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH), but also with any new regulations that may be enacted in the future, in collaboration with our suppliers.
Also, we ask our suppliers to implement the following initiatives to reduce their environmental impact in their business operations.
(1) Reducing CO₂ emissions, (2) Reducing VOC emissions, (3) Reducing amount of waste generated, (4) Reducing water usage, and (5) Promoting energy conservation
We will continue to work with our suppliers to reduce environmental impact and contribute to the realization of a sustainable society.

Management of substances of concern

In recent years, new regulations on substances of concern have been successively introduced on a global basis. Suzuki provides products to customers worldwide and therefore must respond quickly to rapid changes. In light of this reality, Suzuki introduced the IMDS (International Material Data System), a material data collection system for the automobile industry, in 2003, and further used it to build its own in-house environmentally hazardous substances management system (system name: SIDIS = Suzuki IMDS Data Inhouse System) to efficiently collect information on the materials and chemical substances used in each part. We use this information to calculate the recyclability rate, which is a requirement to receive type approval of motor vehicles in Europe, and manage various regulated substances as part of green procurement.
In FY2025, Suzuki provided customers with 39 new models including automobiles, motorcycles, and outboard motors after confirming that these products complied with regulations for substances of concern. In the future, new regulations such as the EU ELV Regulation will require new calculations of the percentage of recycled materials used, so we are currently considering calculation methods and SIDIS specifications as we move forward with these measures. We will reliably comply with these regulations and strive to provide customers with products with low environmental impacts.

In-house Management System for Substances of Concern

* ASR: Automobile Shredder Residue

Promotion of establishment of the substance of concern management system in overseas bases

Green Procurement Guideline operational audit

As a basis for managing substances of concern, we formulated the Suzuki Green Procurement Guideline and started its operation sequentially at major overseas production bases beginning in 2011, and conduct audits aimed at confirming its operation.

Audit for implementation of Asbestos Control Procedures

The use of asbestos is completely prohibited in Suzuki’s technical standards. We established new Asbestos Control Procedures to enforce prohibition of its use, particularly in parts delivered to overseas plants. The procedures require complete prohibition of the use of asbestos by our business partners, and implementing periodic training to relevant parties within the Company. The implementation of these requirements is audited by Suzuki.

(FY2025 Results)

On-site audits (five sites)

• Maruti Suzuki India Limited (India)
• Suzuki Motorcycle India Private Limited (India)
• Suzuki Motor Gujarat Private Limited (India)
  (currently Maruti Suzuki India Limited)
• Suzuki Motor De Colombia S.A. (Colombia)
• Suzuki Philippines Inc. (Philippines)

Promotion of establishing the substance of concern management system at business partners

We collect information about substances of concern in the automobile industry as IMDS data in cooperation with business partners. However, as there have been inaccuracies in IMDS data in the past, we conduct web-based briefings on regulatory trends relating to substances of concern, including requests for accurate IMDS data submissions, as well as audits and guidance concerning strict adherence to Green Procurement Guidelines, and promote the establishment of a substance of concern management system throughout the entire supply chain.

(FY2025 Results)

Companies that were audited and received guidance: 15

Response to Chemical Substance Regulations

We have been working with our suppliers to switch to products that do not contain Dechlorane Plus (DP) and UV-328 which have been designated as substances to be eliminated under the Stockholm Convention on Persistent Organic Pollutants, and have confirmed that all products were free of DP and UV-328 by February 2025. Currently, we are working on switching to products that do not contain MCCP (medium-chain chlorinated paraffin) and LC-PFCA (long-chain perfluorocarboxylic acids) which have also been designated as substances to be eliminated under the Stockholm Convention on Persistent Organic Pollutants (POPs). As initiatives to confirm non-inclusion of regulated substances, we established internal regulations in April 2023 on procedures for complying with regulations to ensure the switchover of regulated substances, and we have been promoting efforts to strengthen post-mass production management, including sampling analysis and confirming that parts do not contain these substances.
Under the EU Waste Framework Directive, registration of product chemical substance information (SCIP) has been introduced, and Suzuki is sequentially registering data for products sold within the EU using IMDS data.

* SCIP (Substances of Concern In articles as such or in complex objects (Products))
A framework intended to make information on chemical substances included in recycled materials more accessible in an aim to transition to a circular economy. This helps to improve the safe use of recycled materials by, for example, removing hazardous substances contained in recycled material rather than using the material in its current state.

<FY2025 Results>

• Confirmation of non-inclusion of DP (Dechlorane Plus) and UV-328 completed
• Promoting switching to non-containing MCCP (medium-chain chlorinated paraffin), and LC-PFCA (long-chain perfluorocarboxylic acids)
• Implementation of sampling analysis of priority control substances, including four heavy metals

Efforts to prevent wastewater spills

Water quality management through analysis

Our environmental analysis departments periodically conduct environmental measurements of water discharges, groundwater, water used in factory processes, and industrial water at our facilities, and strive to prevent contaminant outflow and to manage and maintain water quality appropriately.
In addition, we were registered as an “Environmental Measurement and Certification Business (Concentration)” under the Measurement Act in 1994, and we have continued to conduct measurement and certification of wastewater and industrial waste from Suzuki Group company business locations, thereby promoting group-wide activities for the prevention of contaminant outflow.

Strengthening emergency response

To prepare for environmental risks such as water quality abnormalities and facility failures, we have established emergency communication channels and response procedures. In the event of an abnormality, we have established a system to promptly share information with relevant departments so that we can investigate the cause and implement measures to prevent outflow. We also conduct regular education and drills to ensure we are prepared to respond swiftly and appropriately.

Efforts to reduce chemical substances

Reducing VOCs in the painting process

We are working to reduce emissions of VOC solvents used in the painting process.
In FY2025, total VOC emissions from painting car bodies, bumpers and motorcycles were 3,755 tons/year, while VOC emissions per production unit were 47.8 g/m².
In FY2025, a new painting plant began operations in Kosai in June. The plant introduced water-based paints, Suzuki’s second such plant in Japan, and reduced VOC emissions by 168 tons.
In FY2026, the Kosai new painting plant is expected to operate through the entire year, leading to further reductions in VOC emissions.
We will also continue initiatives to reduce VOC emissions by optimizing painting efficiency through verification of the optimal painting conditions for each process and by introducing devices to collect waste cleaning fluid.

Purchasing new substances

Before our domestic offices and plants adopt new materials such as paint, oil, and detergents, the environmental management department examines the toxicity of chemical substances contained in the materials and the planned amount to be used, as well as how to use and store them, and determines whether or not their use is allowed. The data collected through the research is managed as Pollutant Release and Transfer Register (PRTR) data, which will be used to reduce the volume of those materials. Also, for raw materials, our SDS^* is kept up-to-date to provide the latest chemical data.

* SDS (Safety Data Sheet): A sheet listing the names, physical chemistry behavior, hazards, and cautions for handling, etc., of chemical substances.

PRTR (Pollutant Release and Transfer Register) target substances

To reduce environmental loads, we are working to reduce PRTR target substances. The amount released and transferred was 1,293 tons in FY2025.

Plan for disposal of PCB (Polychlorinated Biphenyl)

The Act on Special Measures concerning Promotion of Proper Treatment of PCB Waste requires appropriate disposal of PCB waste contained in old capacitors, etc., by March 31, 2027. Suzuki is currently working to complete the disposal of this PCB waste. As of March 31, 2026, a cumulative total of 2,884 units of PCB waste had been disposed of at Suzuki’s domestic plants.

Efforts in reducing odor

Although we strictly follow the relevant regulations and laws, odors may still cause discomfort to local residents. Complying with the laws and regulations that form the basis of sustainability is our bare-minimum responsibility, and we will continue to take measures to address sources of odors and deodorize our factories so that our factories will be trusted by local communities.

Efforts to prevent soil and groundwater contamination

Based on historical investigations, we conduct soil surveys when making changes to the character of land that is at risk of soil contamination and are making efforts in remediating and removing contamination appropriately when soil contamination is found.
In FY2025, we conducted 17 soil surveys at our domestic offices and plants, and found soil contamination in three cases. For land where soil contamination has been confirmed, we are managing or remediating such soil appropriately in accordance with the Soil Contamination Countermeasures Act.

Efforts for cleanup of groundwater

Since organic chlorine compounds (trichloroethylene and 1, 2-dichloroethylene) were discovered in the groundwater at the head office and the former Takatsuka Plant in January 1999, we have continued our groundwater cleanup efforts and have conducted measurements along the plant’s site boundaries. In addition, we started bioremediation in March 2015 for groundwater cleanup using microorganisms to complete the purification as early as possible. Through the effects of bioremediation, we aim to complete the cleanup of groundwater contamination.
