Basic policy
Recently, extreme weather events said to be caused by global warming have been occurring frequently. To mitigate these climate change effects, the Paris Agreement was adopted to attain net zero greenhouse gas emissions in the second half of this century, with the aim of limiting the rise in global average temperature to less than 2°C relative to pre-industrial levels. Based on the principles of “Sho-Sho- Kei-Tan-Bi (Smaller, Fewer, Lighter, Shorter, Beauty),” Suzuki has long manufactured products with low CO2 emissions using manufacturing methods that emit low CO2 emissions. We acknowledge that we must now strive to reduce CO2 emissions further in order to meet the so-called 1.5°C target. With this in mind, Suzuki will establish emissions reduction targets aligned with climate science and push ahead with related efforts.
Carbon neutrality achievement targets
JapanEurope────2050
India────2070
Suzuki aims to achieve carbon neutrality by 2050 in Japan and Europe and by 2070 in India, based on the target dates set by the governments of each country.
We will continue our efforts to achieve carbon neutrality targets for each region, based on the concept of expanding customer choices and delivering products and services that meet local needs.
Disclosure based on the TCFD’s recommendations
Governance
Organizational structure related to climate change risks and opportunities
Suzuki has established the Committee for Carbon Neutrality and Environmental Committee, which are executive and business operations committees, and the Corporate Governance Committee under the Board of Directors for the purpose of the Group’s overall environmental management.
The Board of Directors instructs and supervises the Committee for Carbon Neutrality, Environmental Committee, and Corporate Governance Committee, and receives reports from the three committees and is the ultimate decisionmaking body.
The Committee for Carbon Neutrality focuses on the theme of climate change (carbon neutrality) and holds intensive monthly deliberations on decarbonization so the committee can operate more flexibly.
The Environmental Committee meets twice yearly and discusses environment- related themes other than carbon neutrality, such as air conservation, water resources and resource circulation.
The Corporate Governance Committee considers matters related to comprehensive compliance and risk management, etc. and promotes measures and countermeasures for crossorganizational issues while coordinating with related divisions.
Clearly defining the themes of the three committees enhances their effectiveness and further accelerates decision- making toward decarbonization.
- * A subcommittee of the Environmental Committee had previously deliberated on climate change, but in April 2023 this was reorganized as the Committee for Carbon Neutrality and developed as one of the executive and business operations committees.
■ Disclosure and governance based on TCFD recommendations
(As of April 2024)
Strategy
Alignment with the TCFD’s recommendations
In April 2020, Suzuki became a signatory to the Task Force on Climate-related Financial Disclosures (TCFD)* in support of its intent. Along with promoting information disclosure in a manner easily comprehensible to stakeholders, we will work to improve the level of sophistication of our scenario analysis and enhance the content of information to be disclosed in order to further increase our resilience against climate change.
- * Established in 2015 by the Financial Stability Board (FSB), an international organization to ensure the stability of the financial market.
Climate-related risks and opportunities, scenario analysis
Suzuki has been identifying business risks and opportunities to promote business activities in a sustainable manner. Since the impact of climate change, in particular, is intrinsically uncertain, we believe that it is crucial to assess the degree of its impact on risks and opportunities from a broader future perspective and respond appropriately.
Based on this recognition, we have evaluated differences in the impact of climate change on risks and opportunities by using two scenarios. One is the “4°C scenario” in which climate change causes marked physical effects, and the other is the “1.5°C/2°C scenario” in which mitigation measures are being implemented at an accelerated pace toward the realization of the Paris Agreement. In assuming these scenarios, we have referred to externally developed scenarios that are based on the scientific knowledge of the IEA*1, IPCC*2, and other organizations.
- *1 IEA: International Energy Agency
- *2 IPCC: Intergovernmental Panel on Climate Change
Climate-related risks and opportunities for Suzuki
As more stringent laws and regulations, including emission gas, CO2, and fuel efficiency regulations, are being adopted as mitigation measures against climate change, the resulting increase in development expenses needed to comply with these regulations may greatly impact Suzuki’s business performance. On the other hand, small cars, which are a strength of Suzuki, require less materials and energy to produce and emit less CO2 while in use. We believe that we can create opportunities by leveraging such a unique strength of Suzuki and by handling risks appropriately.
Moreover, from the previous fiscal year we have started financial impact analysis based on the scenario analysis related to climate change that we have disclosed. The purpose of this is to reduce and avoid natural disaster risks and enable us to continue our business through assessments of the impact of natural disaster risks such as typhoons, floods, and high tides caused by global warming. We carried out our initial impact assessment on Company sites in Japan and India in addition to domestic primary suppliers.
We will continue to hold careful discussions to reduce or avoid risks caused by climate change, capture opportunities for the future, and increase our competitive edge, and we will incorporate the outcomes of these discussions into our business strategies.

Risk management
Risk management system
The Corporate Governance Committee deliberates on issues that arise or are recognized in each department and identifies and ascertains potential risks, not limiting itself to just climate-related issues. For environment- related risks, either the Committee for Carbon Neutrality or Environmental Committee conducts intensive examination depending on the theme, and instructs or manages departments.
Themes handled by respective meeting bodies
- Corporate Governance Committee
Ascertains risks arising or recognized in each department, deliberates and issues instructions to the department to resolve the issue. - Committee for Carbon Neutrality
Of environment-related risks, deliberates the risks and opportunities related to climate change (carbon neutrality) and resolves and promotes them. - Environmental Committee
Deliberates on environment-related risks and opportunities apart from climate change, such as water resources and biodiversity, and resolves and promotes them.
Envisaged risks related to climate change
For climate change-related risks, we assess risks and their impact under the two scenarios of the “1.5°C/2°C scenario” and the “4°C scenario.” Regarding the types of risks, we observe risks and their impact from the viewpoints of two types, “transitional risks” from policies, regulations, etc., and “physical risks,” from natural disasters, etc.

Acute | Business sites sustaining disaster damage, suspension of business activities, etc. due to more frequent and intensifying natural disasters |
Indicators and targets
Basic policy
Recently, irregular weather phenomena caused by global warming have been occurring more frequently. The Paris Agreement, which aims to limit the increase in global average temperature to less than 2°C above pre-industrial levels and to achieve virtually zero greenhouse gas emissions in the second half of this century, was adopted to suppress the impact of this climate change.
Suzuki has for a long time continued to make products with lower CO2 emissions during manufacture and during use in line with the philosophy of “Sho-Sho-Kei-Tan-Bi (Smaller, Fewer, Lighter, Shorter, Beauty),” and to achieve the so-called 1.5°C target, it has set reduction targets aligned with climate science and promotes efforts with the awareness of the issue requiring a need to further reduce CO2 emissions.
Moreover, emerging countries also need to think about economic growth and not just climate change measures. Suzuki will aim for growth together with emerging countries and promote climate change measures while working to enrich the lives of people in emerging countries.
Suzuki has set multiple climate-related targets and indicators, and promotes these and manages their progress.
Indicators have been set for such matters as CO2 emissions, climate change and related energy, air conservation and water resource conservation. Indicators have been set in three broad areas related to targets and we aim to achieve each of these goals.
Three major indicators have been set according to their timeframe, and we aim to achieve each target.
- Long-term: Suzuki Environmental Vision 2050
- Medium-term: Milestone 2030
Growth Strategy for FY2030 - Short-term: Suzuki Environmental Plan 2025

Efforts regarding product use
Disclosure of GHG emissions in the entire value chain
Suzuki believes that for reducing greenhouse gas (GHG) emissions released through overall business activities, including procurement of materials/parts, manufacturing of vehicles and sale of final products, it is important to know and disclose the emissions from those activities. Therefore, we have been making efforts to quantify the emissions of GHG resulting not only from major business activities, but also from the entire value chain*1 since FY2013.
GHG emissions generated through the entire value chain during FY2023 stood at 108.71 million t-CO2, of which the emissions falling under Scope 3 (indirect emissions from other activities)*1 were 107.75 million t-CO2 that include 85.58 million t-CO2 classified into Category 11 (Use of products sold by Suzuki)*2 accounting for 78.7% of the total emissions through the overall value chain.
Recognizing that it is very important to reduce the CO2 emissions released through the use of our products for reducing the total GHG emissions in the entire value chain, we will make continuous efforts to emphasize improvement of fuel efficiency during product development and improvement.
- *1 Value chain: A method of systematizing how a series of business activities go into the creation of its ultimate value. Calculations are composed of Scope 1, Scope 2, and Scope 3 in accordance with the calculation standard, GHG Protocol*3. The business activities in a value chain include parts and materials procurement, manufacturing, delivery, sales and customer services, as well as administrative work and engineering development work that support these activities. We have been participating in Green Value Chain Platform*4 operated by the Ministry of the Environment and the Ministry of Economy, Trade and Industry since FY2014 and introducing our efforts in quantifying GHG emissions.
- *2 Category 11: This indicates the life cycle GHG emissions from Suzuki’s products sold in the fiscal year.
- *3 GHG Protocol: This is a method to develop calculation and reporting standards for greenhouse gases (GHG) led by the World Resources Institute (WRI), a global environmental think tank based in the U.S., and the World Business Council on Sustainable Development (WBCSD), a conglomeration of companies aiming for sustainable development.
- *4 Green Value Chain Platform: This is an information platform related to value chain emissions operated by the Ministry of the Environment and the Ministry of Economy, Trade and Industry to provide various kinds of information such as domestic and overseas trends and calculation methods, etc. regarding global warming.

Hydrogen engine BURGMAN
Hydrogen can be stored and transported, and it does not emit CO2 when combusted. The only substance given off is nitrogen oxide, which is hardly produced when hydrogen is lean-burned, offering numerous advantages. In recent years hydrogen has drawn attention as a fuel for internal combustion engines.
Suzuki has equipped a large scooter with a hydrogen tank and developed a test vehicle that uses hydrogen as the engine fuel. We are considering the possibilities for hydrogen fuel on two-wheel vehicles.
Efforts for outboard motors
For small outboard motors that are often used in lakes and rivers, we plan to launch four models by 2030 and for a battery EV ratio of 5%.
For large outboard motors used in the ocean, we are considering adopting carbon-neutral fuels.
R&D expenses, capital expenditures
For the development of carbon-neutral and advanced safety technologies we plan to invest ¥2 trillion in R&D and ¥2.5 trillion in capital expenditures, a total of ¥4.5 trillion by FY2030. Of the ¥4.5 trillion, ¥2 trillion will be electrificationrelated investments, of which ¥500 billion will be batteryrelated investments.
For R&D investment, ¥2 trillion is planned for domains including carbon neutrality such as electrification and biogas, as well as autonomous driving. In addition, we plan to invest ¥2.5 trillion for capital expenditures in facilities including construction of a BEV plant and renewable energy facilities.

● Converting to refrigerant with low global warming potential
Under the Act on Rational Use and Appropriate Management of Fluorocarbons (Fluorocarbon Emissions Control Act), refrigerants in passenger car air conditioners shipped to Japan are required to convert to a refrigerant with a lower global warming potential from FY2023 onward.
Suzuki has until now used HFC-134a as a passenger car air conditioning refrigerant, but as this has larger global warming potential, we developed HFO-1234yf, a refrigerant that has an extremely low global warming potential, and completed conversion of use to HFO-1234yf in all passenger cars to be shipped to Japan by the end of FY2022.
TopicsSuzuki competes in Suzuka 8 Hours Endurance Race 2024 using sustainable fuel
Suzuki competed in the 2024 FIM World Endurance Championships “Coca-Cola” Suzuka 8 Hours 45th Annual Race, held on the Suzuka Circuit in Mie Prefecture from Friday, July 19 to Sunday, July 21 and used multiple sustainable items including the fuel.
The fuel used by Suzuki for the race was the FIM* official sustainable fuel that is 40% bio in origin. This fuel is not the official fuel of the FIM Endurance World Championships (EWC), so we competed in the Experimental Class. Along with sustainable fuel, we took on the challenge of developing new sustainable technologies for the tires, oil, cowls, and brakes, etc. with partner companies that sympathized with the project.
The race team were primarily members selected from inside Suzuki and made up the Team Suzuki CN Challenge. The team worked with partner companies and while overcoming challenges completed the race.
The race is intended to accelerate development of environmental performance technologies through actual driving under the severe conditions of an endurance race. By examining invaluable data obtained from the race, even higher goals have been set and we will promote technical feedback in products going forward.

Hyperfuels PurFuels™ is a sustainable fuel that can be “dropped-in”; it can be used in all existing gasoline outboard engines without any special adjustment. It is made by refining cooking oil waste, plant-based materials, etc. This specific formulation of PurFuels™ reduces CO2 emissions by 30% more than E10 (ethanol blended) fuels at the same renewable content.
Suzuki Marine USA will conduct trial introduction of Hyperfuels PurFuels™ in its daily development operations at the Technical Center to contribute to the reduction of CO2 emissions. Additionally, in collaboration with NMMA and local stakeholders, we will participate in a project to promote widespread use of sustainable fuels in marinas in the Florida Panhandle. Starting with a city-owned marina in Panama City, we plan to expand the project statewide in the future.
Through the introduction of sustainable fuel, Suzuki will contribute to enriching the boating experience of customers in the United States and achieving carbon neutrality of our marine business.

Reduction of CO2 emissions
The Paris Agreement, which is an international framework aimed at reducing greenhouse gas to limit global warming, has been enacted, and governments of various nations and companies worldwide are promoting actions to reduce the emission of greenhouse gases in order to realize the target of limiting the rise of the global average temperature to less than 2°C.
We consider that it is important to globally promote a reduction of CO2 emissions from plants in order to reduce the effects of greenhouse gas emissions, and make efforts to reduce the amount of CO2 emissions per production unit (automobile production units) of Suzuki’s global manufacturing units by 25% (compared to FY2016) by FY2025 in accordance with the Suzuki Environmental Plan 2025.
The total amount of CO2 emissions from manufacturing activities in FY2023 was 835,000 t-CO2/year at Suzuki overall on a global scale, 176,000 t-CO2/year in Japan, and 660,000 t-CO2/year overseas. The amount of CO2 emissions per manufacturing unit was 0.256 t-CO2/unit.
As reduction initiatives, aside from activities for saving energy and eliminating waste, Suzuki is working to expand solar power generation both in Japan and overseas. In addition, CO2-free electricity was gradually introduced starting in July 2023 at all production sites in Japan.
We will continue to further promote the effective use of energy and work to reduce intensity.

● Energy-saving activities at plants
All employees participate in daily activities such as reducing air leaks, turning off lights during breaks, and switching off power when plants are not in operation. These efforts are steadily producing results each year.
Also, when upgrading the deteriorated production equipment or introducing new equipment for production of new models, we work on building more effective energy-saving plants than ever before by utilizing gravity, downsizing and reducing the weight of equipment, and adopting highefficiency devices such as LED lights and top-runner devices (motors, transformers).
Furthermore, as one of Suzuki’s efforts to reduce CO2, we are reconfiguring our supply of energy, such as by converting fuels from LPG to city gas at the Osuka Plant and Iwata Plant. We will also extend this conversion to the Sagara Plant.
The amount of CO2 reduction at domestic and overseas plants and reduction according to activities are shown on the right.

TopicsUtilizing air conditioning that uses groundwater and radiators
The Suzuki Group carries out various energy-saving activities. Of them, we will introduce energy-saving initiatives for air conditioners that use radiators.
This energy-saving initiative utilizes radiators and groundwater, whose temperature is stable throughout the year.
Specifically, groundwater and radiators are used to lower the temperature of intake air drawn from the atmosphere. This reduction in intake air temperatures in the air handling unit helps save energy when cooling and heating. The amount of LPG used in the air handling unit is reduced by approximately 0.4 Nm3/h.
This energy-saving initiative brought to life an idea from a workplace and is an example of taking on a challenge from a new angle. We will promote carbon neutrality by continuing to make improvements from various perspectives, as with this initiative.
● Promoting the use of renewable energy
Suzuki promotes the use of renewable energy as an integral part of its global warming countermeasures.
Suzuki is proceeding with the installation of solar power facilities at its domestic plants, which it has been working on from before, and has introduced these facilities on land adjacent to the Sagara Plant (Makinohara) as well as at the Hamamatsu Maisaka-Nishi Solar Power Plant, and Hamamatsu Plant. We also partially began solar power generation at the Iwata Plant in 2021 and the Kosai Plant in 2022, and intend to continue installing solar power facilities at other plants in the future.
Suzuki has also installed two wind power generation facilities at the Kosai Plant and one at its training center.
At overseas plants, Maruti Suzuki India Limited, Suzuki Motor Gujarat Private Limited, and Suzuki Motorcycle India Private Limited have introduced and are further expanding solar power generation facilities.
We will actively promote the use of renewable energy, both in Japan and overseas.

Efforts in office activities, etc.
Efforts at data centers
We promote energy savings by expanding use of IT technologies for analysis and calculations and work to reduce energy consumption by efficiently operating IT devices, which are increasing.
● Improving coolant efficiency and converting to high environmental performance facilities
In July 2023, we zoned off server waste heat from intake side cool air and installed a containment system that keeps them separated at server rooms with heavy loads. Electricity consumption by air conditioning facilities was reduced by 114,000 kWh per year compared to FY2022. In addition, by steadily changing to high-efficiency-type air conditioning units, the ratio of IT device electricity consumption and air conditioning electricity consumption has been improved from 2:1 in FY2019 to 3:1 in FY2023.
What’s more, in January 2024, we updated uninterruptible power supplies to those with low electricity loss and reduced monthly electricity by 8,500 kWh (100,000 kWh yearly).
Efforts at offices
We determined the guidelines for energy saving action in FY2008, and promote energy saving at offices and the reduction of CO2 emissions through a group effort involving all employees.
● Guidelines for energy saving action
We have established a guideline for energy saving action as a part of In-house Cost Cutting Activities, which covers a wide range of activities, for the purpose of promoting energy saving (CO2 reduction) by individual employees.
[Guidelines for In-house Cost Cutting Activities (Excerpt)]
- (1) Follow the predetermined temperature settings of air conditioners (cooling at 28°C and warming at 20°C)
- (2) Turn off unnecessary lights
- (3) Save electricity of electrical appliances
- (4) Implement eco-driving
- (5) Computerize documentary forms and minimize printouts of electronic data

Efforts in procurement
Efforts in the supply chain toward carbon neutrality
To achieve carbon neutrality (net zero CO2 emissions) by 2050, it is essential to reduce CO2 emissions in the supply chain, which accounts for approximately 90% of the CO2 emissions from manufacturing.
Suzuki has been working toward carbon neutrality in its supply chain since 2021. In 2022, we established a dedicated department and began to calculate the CO2 emissions of each business partner by fiscal year and by component in order to gain a detailed understanding of their CO2 emissions.
In addition, to achieve carbon neutrality by 2050, we have asked our business partners to set CO2 emission reduction targets and roadmaps for 2030 and have begun reduction activities, such as checking the feasibility of reduction items. We cooperate with our business partners to reduce CO2 emissions by visiting their manufacturing sites to confirm on-site examples of improvement initiatives, identify issues in carbon neutrality efforts, and listen to their concerns.
Also, since FY2022 we have worked to promote carbon neutrality activities by designating small and medium-sized business partners taking exceptional initiatives for carbon neutrality as “CN Contributors” and honoring them with letters of appreciation.
We will continue cooperating with our business partners to achieve carbon neutrality.
Efforts in domestic transportation
● CO2 reduction activities in domestic transportation
(FY2023 initiative results)
We are trying to improve transportation efficiency by reducing transportation distance by revising routes, promoting modal shift, and increasing fuel efficiency of transportation vehicles, etc. in order to reduce CO2 emissions in domestic transportation.
As a result of our transportation efficiency efforts thus far, CO2 emissions from transportation per net sales in FY2023 have improved by 35.8% since FY2016.
■ Trends in CO2 emissions from domestic transportation
● Modal shift of a portion of truck transportation to rail transportation
We have reduced CO2 emissions through the modal shift from trucks to rail, which is more energy-efficient, for regular freight transport from a parts plant in Kosai City, Shizuoka Prefecture to a transportation base in Kyushu.
● Establishing a transportation base and a modal shift to ship for some transportation to the base
In December 2022, we launched Suzuki Parts Center Tomakomai to serve as a transportation base for parts and supplies bound for Hokkaido. With the establishment of the new base, we conducted a modal shift by transporting around 80% of what had been taken by truck to Hokkaido by ship transportation, thereby reducing CO2 emissions from transportation.
