We will promote development of vehicles with the top-class low fuel consumption and next-generation vehicles in order to reduce CO2 emission, which is regarded as the cause for global warming. In addition, we will thoroughly conduct Energy-saving in production and distribution, and promote efficient business operations.

Efforts for climate change

Problems with global environment are the big theme for sustainable development of human, and Suzuki believes that we must cope with these problems as a global enterprise. In particular, we must work on global warming as an important theme.

Suzuki’s responsibilities and efforts for global warming

Discussions on global warming have been promoted internationally and the international rule to reduce the use of fossil fuel that causes CO2 emissions, “Paris Agreement” was established.
In addition, the Suzuki Global Environment Charter determines “Environmental Concept” as “In order to hand over the beautiful earth and affluent society to next generations, we must all realise that the actions of each and every one of us have a great effect on our earth’s future, so we must make every effort to preserve our environment.”
Suzuki has an important task that we must be always aware of that we manufacture products using fossil fuel and emit CO2 also during our business operations, and have to make efforts to reduce CO2 emissions.

Efforts for products

Under the slogan “Small cars for a big future”, Suzuki works toward manufacture of eco-friendly products. We promote reduction of CO2 emissions by promoting downsizing, weight reduction, improvement in combustion efficiency, and reduction in resistance for all products.
We promote reduction of CO2 emissions also by introducing the next-generation technology such as development of mild hybrid technology to compact/mini passenger cars, development of a hybrid vehicle adopting Suzuki’s original AGS mechanism, and sales of electric scooters.
In order to reduce CO2 emissions furthermore and realise zero emissions in future, we promote the test of a fuel cell motorcycle on public roads and development of compact EVs suitable for daily life.

Changes in sales mix in Japan

Efforts for business operations

The target of global CO2 reduction is set in the Suzuki Environmental Plan 2020, and we promote reduction of CO2 emissions at all of our manufacturing bases in the world by 2020.

Disclosure of GHG emissions occurred in the entire value chain

Suzuki believes that for reducing greenhouse gas (GHG) emissions released through the overall business activities including procurement of materials/parts, manufacturing of vehicles and sale of final products, it is important to know and disclose the amount of emission from those activities. Therefore, we have been making efforts to quantify the emissions of greenhouse gases not only resulting from major business activities, but also from a wider scope of the value chain*1 since FY2013.
The amount of CO2 emissions generated through the entire value chain during FY2016 stood at 72.59 million tons, of which the emissions falling under Scope 3 (other indirect emissions than those classified into Scope 2)*1 were 71.47 million tons that include 61.49 million tons of CO2 emissions classified into “Category 11 (Use of products sold by Suzuki)”*2 accounting for as much as 84.7% of the total emissions through the overall value chain.
Recognising 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 place emphasis on improvement of fuel efficiency at the time of product development and improvement.

  • *1 Value chain: This is the whole series of business activities that create and build values at every step. Calculations are composed of Scope 1, Scope 2, and Scope 3 in accordance with “GHG Protocol”*3 The business activities in a value chain includes parts/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 Environment and the Ministry of Economy, Trade and Industry since FY2014 and introducing our efforts in quantifying the emissions of greenhouse gases.
  • *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 collaboration of the World Resources Institute (WRI), a global environmental think tank based in the United States, and the World Business Council on Sustainable Development (WBCSD). It is the most widely used international accounting tool to quantify and manage greenhouse gases (GHG).
  • *4 Green Value Chain Platform: This is a website operated by the Ministry of the Environment and the Ministry of Economy, Trade and Industry to provide various kinds of global warming and GHG emissions related information such as internal and external trends, calculation methods, etc.

Trends in global reduction rate of amount of CO₂ emitted during product use (passenger car)

Fuel efficiency improvement technology

Various technology development and improvement are adopted on our automobiles.

Major fuel efficiency improvement technologies and initiatives

Development of “Solio HYBRID” and “Swift HYBRID”

The "hybrid system" adopted in Solio and Swift is produced by evolving hybrid technologies developed through “mild hybrid”, and realises 1) lightweight and compact system, 2) enhanced fuel efficiency, 3) EV driving and 4) direct feeling of driving by combination of AGS and MGU. This system was first installed in Solio launched in November 2016 and then adopted to Swift launched in July 2017.

  • *MGU=Motor Generator Unit

Features of hybrid

System component

Development of engine

Newly developed a 1.0L direct-injection turbo engine that realises both fuel efficiency and power

The displacement is as small as 1.0L, but direct-injection and turbo charger realise high output and high torque equivalent to 1.6L naturally aspirated (NA) engine. In addition, rigidity is improved as increase in output, and excellent silence is realised by taking the countermeasures for vibration and noise in a 3-cylinder engine, This engine is easily operable and shows excellent performance in a wide variety of scenes from driving in cities to high-speed driving.

Direct-injection technologies

We adopt the direct-injection engine that directly injects fuel to the cylinders. Fuel consumption is regulated by optimally controlling the quantity of fuel injection, timing and fuel pressure, and ensuring effective combustion. In addition, cooling effects realised by injecting fuel directly into cylinders improve the anti-knocking performance.

Adoption of 6-hole side injection and variable fuel pressure control

In order to further stringently and constantly control fuel injection, we adopt the side injection type for which multi-hole injectors having 6 injection holes are arranged in a row.
In addition, high atomisation of spray is promoted by raising fuel pressure with the high-pressure fuel pump. The optimum air-fuel mixture is formed and combustion efficiency is improved.

Image of direct-injection in cylinder

Waste gate valve normal open control

We adopt the waste gate valve normal open control for control of turbo charging pressure. The valve is opened during constant-speed traveling and closed during acceleration or high-speed traveling to adjust the inflow of exhaust gas. Turbo charging pressure is finely controlled to realise both power performance and fuel efficiency.

Countermeasures for vibration and noise

Vibration and noise prevention performance is sufficiently secured by optimising the flywheel inertia and crank shaft balancer weight and improving rigidity of the cylinder block, crank shaft, etc.

Improvement of Transmission

Improvement in fuel efficiency through adoption of CVT (Continuously Variable Transmission) with an auxiliary gearbox, and its expanded adoption

CVT with an auxiliary gearbox, which covers a wide range of transmission gear ratio, was first adopted on the Palette launched in September 2009, and is now installed on all of Suzuki’s mini passenger vehicles and compact passenger vehicles of 1.0L to 1.6L classes.
CVT friction was reduced by employing low viscosity CVT fluid and using a ball bearing for the CVT differential side bearing since November 2011. Then, since the new Alto launched in December 2014, we used an allowance of driving force generated by weight reduction of the vehicle to heighten the final drive ratio and improved fuel efficiency.

Expanded adoption of Auto Gear Shift (AGS) for domestic minivehicles

Since it was first adopted on Celerio launched in India in February 2014, the Auto Gear Shift has been widely adopted in domestic minivehicles, such as Carry, Alto, Every, Alto Turbo RS and Alto Works step by step. Auto Gear Shift has both the convenience of automatic transmission and the fun of operating manual transmission, and has the same basic mechanism as the lightweight and high efficiency manual transmission. Plus, it incorporates a computer-aided gear change system for optimum operational control thereby ensuring higher levels of fuel efficiency than conventional automatic or manual transmissions.

Development of ECO-COOL, an air-conditioning system

Suzuki developed an air-conditioning system with freezable substance “ECO-COOL”, which is designed to satisfy both comfort and fuel efficiency requirements by freezing the substance with the cold air emitted from the air-conditioner during running, and blowing the cool air through the frozen substance with a fan during idle-stop. This system has been installed in WagonR, Spacia, Hustler, Alto, Alto Lapin, Swift, Solio, and Ignis.

Extension of duration of engine shutdown and improvement in comfort

We extended duration of engine shutdown from the point the engine shuts down under a comfortable condition up until the car cabin temperature reaches the limit of comfort, to approximately twice*1 as much as the duration of vehicle without ECO-COOL.

Reduction of body weight

Efforts in weight reduction

Thorough weight reduction is pursued throughout the whole vehicle body.
Swift XG 2WD 5MT launched in January 2017 realised weight reduction of approximately 120kg*1, which makes it one of the lightest body weight in its class*2 at 840kg.

  • *1 Comparison between previous Swift XG 2WD 5MT and new Swift XG 2WD 5MT
  • *2 Petrol car in the compact car class (engine displacement of at least 1000cc)

Weight reduction contribution ratio of Swift XG 2WD 5MT

Weight reduction by adopting new platform HEARTECT

Suzuki adopts new platforms one after another.
The rigidity for the current underbody is ensured by using reinforcement materials for each section. However, the new underbody is designed to be a smooth shape that receives and disperses input from the outside, avoiding corners where forces are concentrated as much as possible. This design reduces reinforcement materials and realises weight reduction.
The rigidity of the body is improved with smaller quantity of materials, as well as the steel sheet thickness itself is reduced by making the optimum shape.

Weight reduction by adopting ultra high tensile steel sheet

We frequently use ultra high-tensile steel sheet to sections related to deformation upon collision in order to satisfy the target collision performance, while uisng thinner sheet with reduced weight.
We achieved “Light Weight Index” of which smaller value means that the body is highly rigid and lightweight of 3.03 (improved by 13% compared to the previous Swift).

Weight reduction of suspension system

Suspension system has been newly designed according to the new platform.
The new design realised weight reduction of approximately 12kg from the previous model.

Weight reduction of steering column and gear box

Weight and space of column has been reduced while enhancing rigidity of fixing support by reviewing the structure of the column.
Also, weight of steering gear box has been reduced by adopting hollow rack bar.

Weight reduction of seat frame

In the front seat frame, thinning of materials by employing super hightensile steel plate of 980MPa class in wider range and integration/downsizing of components is thoroughly performed, and weight reduction is realised while ensuring comfortable seating and durability. In addition, the layout is changed together with the platform to make the frame structure which realises light weight, rigidity and safety all at the same time.
As for the rear seat frame, back frame structure has been reviewed. By welding the back lower hinge and back lock striker to the body, which were conventionally fixed with bolts, weight reduction is realised through reduction of fixing parts and reinforcements.

Weight reduction of interior parts

Thorough weight reduction is made throughout the whole cabin by thinning and optimising the structure. Also at the same time realised cabin space with excellent comfort and silence.

Weight reduction of engine

Compared to K12B type engine, K12C type DUALJET engine is made compact by reducing the tilt angle from 15° to 5°. In addition, weight is reduced by approximately 4% by employing the intake manifold structured with integrated EGR pipe and changing the shapes of the crank shaft and cylinder block.

Use of tailored blanks

Tailored blank is a manufacturing method by which steel parts having different thicknesses or materials (high-tensile steel plate, plated steel sheet, etc.) are welded in advance with laser welding, etc., and then pressed. By applying this method to various panel components, it is possible to partially reinforce specific portions of the same component, without adding any part, thus avoiding weight increase.

Extensive use of high-tensile steel plate

By adopting high-tensile steel plate with excellent strength, the number of reinforcement parts and the entire weight are reduced, and the body strength is enhanced. We started using super high-tensile steel plate with TS* of 980MPa for WagonR from its third generation model launched in September 2003, and also adopted a higher tensile type (TS of 1180- MPa class) to the floor side member of the Spacia launched in March 2013. For the WagonR launched in February 2017, we expanded the use of super high-tensile steel plate and realised further weight saving, while ensuring the same or greater level of collision energy absorption capability than the previous model.

*TS: Tensile Strength

Lightweight index, evidence of high rigidity and lightweight body, is 4.16

For the WagonR launched in February 2017, we realised higher rigidity together with weight reduction. As for the “Lightweight Index” which means that the body is more rigid and lighter when the value is smaller, efficiency was improved approximately by 17% compared to the previous WagonR.

Reduction of air resistance

Swift realised excellent aerodynamic performance while paying attention to design that has the image of compact and brisk driving. Computer simulation was fully utilised from the design phase, and a wind tunnel test was thoroughly conducted using a clay model or prototype vehicle in pursuing aerodynamic performance. In particular, ideal wind flow is made by smoothly flowing the stream from the front to the rear, and suppressing the wind flow in the rear. In addition, we optimised the shape of the strake that prevents wind against tires and of the engine under cover to rectify the entire air flow under the floor. This reduced air resistance and improved fuel efficiency.

Installation of eco-drive supporting devices

Installing fuel efficiency indicator

Suzuki has been increasing the number of vehicles equipped with eco-drive supporting devices, such as a fuel efficiency indicator. In FY2016, such devices were installed in 13 out of 16 types of vehicles

Adoption of status information lamp, etc.

In FY2016, the eco-drive indicator or eco-drive assisting light or status information lamp has been incorporated in 10 types of vehicles. When the accelerator movement indicates proper driving state for fuel economy, the eco-drive indicator located in the meter panel lights up and stays on or the light on the meter turns from blue to green. The driver can recognise eco-driving at a glance and fuel efficiency can be improved.

Status information lamp
Colour of the meter turns from blue to green during fuel-efficient driving, and turns to white when regenerating deceleration energy.



Adoption of ECO-score

We adopted the ECO-score on 10 types of vehicles in FY2016. Operation when turning on the key and then off is marked out of 100 in real time according to achievement level of eco-drive. In addition, the average score for one driving is shown when the ignition is OFF.


Technologies for improving fuel efficiency

Activity for all models

We are trying to enhance fuel efficiency by promoting to improve combustion, reduce friction loss, and reduce vehicle weight.

Improvement in engine

Example of applied product

GSX250R launched in April 2017 combines output character that emphasises ease of use in the low- to mid-speed range most frequently used for city riding, to excellent fuel efficiency, thanks to improvement of combustion and reduction of friction loss of 248cm3 water-cooled two-cylinder engine. Compared to Suzuki’s conventional model, it realises approximately 8%* improvement of the fuel efficiency.

*Comparison of values measured in WMTC mode.

Adopting roller rocker

The cylinder head adopts roller type rocker arms that minimise friction loss.

Optimising piston rings

Thin, low tension piston rings were adopted to reduce friction.

Optimising cylinder processing

The honing pattern used for the cylinder barrels maintains lubrication for the pistons in a manner that helps minimise any loss of performance due to friction.

Optimising oil pump

Optimisation of the oil pump reduces friction loss and contributes to an increase in engine output and improvement in fuel economy.

Adopting projected spark plugs

Adopting the use of projected tip spark plugs speeds up the rate of combustion.
This improves response, especially when the throttle is not open far, and also improves fuel economy.

Weight reduction of body

Improvement of frame

For GSX-R1000/R, the main frame weight was reduced by approximately 10% compared to the aluminum frame of the previous model by optimising the material thickness and cross-sectional shape. In addition, the component structure was simplified to realise high productivity and durability by optimising welding positions of components. We realised lightweight and slim body by optimising rigidity balance and suppressing the body width.
For seat rail, production process was reviewed to aluminum pipe, and by optimising cross-sectional shape and pipeline, the seat rail weight was reduced by approximately 40% compared to the aluminum diecast seat rail of the previous model.

Reduction of air resistance

For GSX-R1000/R, air resistance (CdA value) is reduced by approximately 6% by making the exterior parts into a smooth, flowing shape that optmises the air flow, while also making the frontal projection area smaller by approximately 5.5% compared to the previous model. This was made possible by wind tunnel testing and flowage analysis.

Installation of eco-drive supporting devices

Installing fuel efficiency indicator

Suzuki has been increasing the number of vehicles equipped with eco-drive supporting devices, such as a fuel efficiency indicator. As of FY2016, such devices are installed in 16 types of models.

Adoption of eco-drive indicator

As of FY2016, the eco-drive indicator is adopted to 3 types of models. This indicator stays lit during proper driving state for fuel economy to prompt the user to do throttle work for better fuel efficiency and supports improvement in fuel efficiency.

Outboard motor

Improvement in fuel efficiency

Suzuki has tried to develop and improve the product focussing on improvement in fuel efficiency in order to reduce CO2 emissions amount that are considered as a cause of global warming. In FY2016, we launched two models of outboard motors DF150AP/175AP that adopted the lean burn system. The fuel efficiency of DF150AP is improved by up to 4% compared to the previous model, by suppressing rise in intake air temperature using the semi-direct intake system, increasing compression ratio and adopting the lean burn system etc., without changing the basic engine of inline 4-cylinder with total piston displacement of 2,867cm3.

Improvement rate of fuel efficiency (If the previous model's value is taken as 100)

Fuel efficiency improvement technologies

DF150AP/175AP improved output and fuel efficiency by designing to lead air outside the engine cover to the throttle body through the air intake duct and adopting the semi-direct intake system that regulates rise in intake air temperature due to radiation heat from the engine.

[Product development] Development and technologies of next-generation vehicles

Efforts for fuel cell vehicles

We have promoted the development of BURGMAN Fuel Cell which is equipped with the compact, lightweight and low-cost air-cooled type fuel cell system, and started driving on public roads using the type-certified vehicle.
According to the safety standards for fuel cell motorcycles of the Road Vehicles Act proclaimed/enforced in February 2016 by Ministry of Land, Infrastructure, Transport and Tourism, we applied for vehicle type certification of BURGMAN Fuel Cell and acquired it in August 2016.
We obtained the license plate of BURGMAN Fuel Cell in March 2017 and started driving on public roads. Using hydrogen stations built in Shizuoka Prefecture, Fukuoka Prefecture, etc., we are studying marketability of fuel cell motorcycles.

[Design, development] Reduction of Freon

Reduction of Freon

Since such fluorocarbon refrigerant as HFC-134a currently used in car air conditioners has a high global warming potential, we are now making efforts to reduce the amount of it used in our vehicles. At the same time, we are now developing a next-generation air-conditioning system using an environmentally friendly refrigerant HFO-1234yf that has an extremely low global warming potential.

[Production, distribution] Energy-saving for business operations

Greenhouse gas emissions from business operations

“Paris Agreement” which is the new international framework for reducing greenhouse gas and regulating global warming was enforced, and governments and companies are globally promoting efforts to reduce greenhouse gas in order to suppress the rise of global average temperature to “less than 2°C”.
Suzuki has been making efforts to reduce CO2 emissions at our locations in Japan (plants, experiment facilities, offices, etc.) according to “Suzuki Environmental Plan 2015” in order to reduce greenhouse gas that we generate through our business operations.
Global emissions of greenhouse gas including our subsidiaries in FY2016 was 560,000t-CO2 for direct emissions (scope 1), 560,000t-CO2 for indirect emissions (scope 2), and 1,120,000t-CO2 in total. When classifying the emissions to those from plant and from locations other than plants (experiment facilities, offices, sales dealers, etc.), the emission from the plant was 88.8% (FY2016) of the total emission. In addition, the ratio of the emissions overseas is 54.2% (FY2016) of the whole.
Therefore, Suzuki recognises that it is important to globally promote reduction of CO2 emissions at plants in order to reduce greenhouse gas in “Suzuki Environmental Plan 2020”, and will continue improvement activities.

[Production, distribution] Reduction of CO2 emission for manufacturing activity

CO2 emissions amount per global production units

The target of reduction of CO2 emissions used to be reduction of the total emissions from domestic offices by 15% in FY2015 regarding FY2005 as the base year (achieved the target with 16.9% reduction as the result). However, since FY2016, regarding the global production volume (converted to the number of automobiles) of domestic and oversesas Suzuki Group manufacutirng companies as the denominator of basic unit and FY2010 as the base year, we determined to reduce the CO2 emission basic unit by 10% by FY2020 as our target.
The total emission of energy-derived CO2 from Suzuki and its domestic group manufacturing companies was up by 5.6% from the previous fiscal year to 397,000 tons in FY2016, and the total emission of energy-derived CO2 from overseas group manufacturing companies was up by 8.6% from the previous fiscal year to 595,000 tons in FY2016. The total CO2 emission per global production units (converted to the number of automobiles) was up by 2.6% from the previous fiscal year and down by 1.3% compared to FY2010, to 0.311 ton per unit.
In India, where public electric service is not so good, almost all power used in the plant needs to be supplied through inhouse power generation, and about 70% of CO2 emissions come from the power generation equipment. However, efforts are made to reduce CO2 emissions by using natural gas which generates less CO2 for power generation and by adopting solar energy generation and combined cycle power generation that can generate electricity from the vapor coming from the exhaust gas emitted from the power generation equipment.

Energy-saving activities at plant

Large energy-saving effects were acquired by remodeling various processes according to production volume, such as consolidation of assembly plants of Kosai Plant (from 3 plants to 2 plants), reduction of machine downtime rate per operation in the cast process and machining process, and reduction of steam sending pressure (from 0.58MPa to 0.56 MPa).
Also, when upgrading the deteriorated production equipment or introducing new equipment for production of new models, we promote to build a more effective energy-saving plant by utilising gravity, downsizing and reducing weight of equipment, and adopting high-efficient devices such as LED light and top-runner devices (motors, transformers).
Besides energy-saving countermeasures requiring equipment investments, all workers perform steady activities such as reducing air leakage and turning off the light during break time.

*“Reduction of air leakage” is an activity to reduce leakage of compressed air from hose etc. used in the plant by appropriate maintenance etc.

Total CO₂ reduction amount and reduction amount by activities of domestic plants and overseas group manufacturing companies

Promoting the use of alternative energies

As part of global warming countermeasure, Suzuki is promoting the use of alternative energy in Japan by introducing two wind force power generation systems and a small-scale hydraulic power generation system (using industrial water receiving pressure) into Kosai Plant, and also installing one wind force power generation system in a training center.
Concerning overseas sites, the 1-MW solar energy generation system started operation at the Manesar Plant of Maruti Suzuki India in FY2014.
We will promote conversion to fuels which generate less CO2, use of natural energies, etc. both in Japan and overseas.

Energy saving efforts at data center

At Suzuki’s data center, the following efforts and activities have been implemented to reduce the yearly increasing power consumption.

Integration of servers

Previously, individual departments procured servers respectively. As a result, a lot of similar servers exist in the data center. In FY2015, procurement of servers by individual departments was stopped, and all arrangements are now done by the Global IT. A large server called “integrated server” is installed and segmented with the use of “virtual technique”, and necessary server functions are distributed according to the requests from individual departments.
At the same time, the existing servers are being integrated into the integrated server step by step.
We will conduct this measure continuously.

Transition to UPS* shared by data center

We found that small UPS’s were installed in individual racks although a large common UPS was installed in the data center, and this wastes electricity. So, we are trying to reduce power consumption by removing all of small UPS’s from the racks and completely transferring the functions to the UPS shared in the center.

*UPS: Uninterruptible Power Supply

Adoption of task-ambient air conditioning

Recently, densification and high integration is promoted for servers. In particular, we can see this clearly in servers related to engineering. Therefore, Suzuki strive to save energy by installing the task-type air conditioning system for a high temperature generating element such as the CAE* server and combining it with the conventional package-type air conditioning system installed near the wall.

*CAE: Computer Aided Engineering

Other efforts

We are trying to make more efficient energy-saving measures by actively adopting the energy-saving diagnosis by a local government or professional vendor to clarify problems.
We also examine to introduce the automatic air-conditioning control system for the data center.

Promotion of CO2 emission reduction at offices

We determined the standard of employee behaviour in FY2008, and all of our employees are getting together to promote energy saving at offices and reduction of CO2 emissions. In addition, we put the progress of each activity in relation to the standard of employee behaviour on the in-house homepage so that individual employee can check the result of their activities.

We have established a standard of employee behaviour (for In-house Cost Cutting Activities), which covers a wide range of activities, for the purpose of promoting energy saving and CO2 reduction by individual employees.

[Standard of Behaviour for In-house Cost Cutting Activities (Excerpt)]

  • ① Follow the predetermined temperature settings of air conditioner (cooling at 28°C and warming at 20°C).
  • ② Turn off unnecessary electric lights.
  • ③ Save electricity of electric appliances.
  • ④ Implement eco-drive.
  • ⑤ Computerise documentary forms and minimise printout of electronic data.

Visualisation of energy consumption specified in the standard of employee behaviour

To allow individual employees to check the effect of energy saving activities, we put the changes in electric consumption at each of major offices and plant buildings, consumption of printing paper, and energy consumption specified in the standard of behaviour on our in-house homepage.

Introduction of energy saving facilities

We are promoting introduction of LED lighting since FY2012 to promote energy saving at offices.
We changed up to approximately 77% of the light in offices to LED in FY2016.

[Production, distribution] CO2 reduction in domestic transportation

Enhancement of transportation efficiency by reviewing transportation route and packing style

Shortening transportation distance (automobile engines)

Until July 2015, for assembling compact cars at Kosai Plant, a part of the engines manufactured at Sagara Plant were transported approximately 80km to Kosai Plant. From August 2015, assembling of compact cars was moved to Sagara Plant. By doing so, manufacturing of engines and assembling of compact cars are both conducted at Sagara Plant, thus shortening transportation distance.

Enhancement of transportation efficiency (motorcycle)

For efficient product transportation from production plants to dealers, distribution bases have been centralised in a large consuming region. Also, for transportation from the distribution bases to dealers, cooperative transport with other companies is conducted to increase transportation efficiency.

Enhancing fuel efficiency of tranportation vehicles and promoting modal shift

For domestic transportation of automobiles, Suzuki uses two types of transportation methods: by land using trucks and by sea using ships. For land transportation, we are working on improving average fuel consumption by promoting eco-drive at consigned transportation companies and switching to new vehicles. Approximately one third of completed automobiles for the domestic market are currently transported by sea. We will continue to review ways of distribution as needed and promote improving transportation efficiency such as by modal shift.

CO2 reduction in domestic transportation

We are trying to reduce transportation distance, improve transportation efficiency, promote modal shift, increase fuel efficiency of transportation vehicles, etc. in order to reduce CO2 emissions in domestic transportation.

CO2 emission in FY2016 was reduced by 33% compared to FY2006, and down by 2% year-on-year to 38,800t-CO2.
CO2 emission basic unit per sales was improved by 24% compared to FY2006.
