GLOBAL SUZUKI

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.

Reduction in amount of CO2 emitted

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 global CO2 emissions per production volume* at all of our manufacturing bases in the world by 10% from FY2010 by 2020.

*Value converted to global automobile production units based on CO2 emissions ratio per unit of automobile, motorcycle and outboard motor in Japan.

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 FY2017 stood at 78.62 million tons, of which the emissions falling under Scope 3 (other indirect emissions than those classified into Scope 2)*1 were 77.42 million tons that include 66.78 million tons of CO2 emissions classified into “Category 11 (Use of products sold by Suzuki)”*2 accounting for as much as 84.9% 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.

Breakdown of FY2017 GHG emissions

  • *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 the 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.

Topics Development of electric vehicles (EVs)

In November 2017, Suzuki and Toyota Motor Corporation concluded a memorandum of understanding on moving forward in considering a cooperative structure for introducing electric vehicles (EVs) in the Indian market in around 2020.
Specifically, Suzuki is to produce EVs for the Indian market and will supply some to Toyota, while Toyota is to provide technical support. Additionally, Toyota and Suzuki intend to conduct a comprehensive study of activities for the widespread acceptance and popular use of EVs in India. Such activities encompass the establishment of charging stations, human resources development that includes training for after-service technicians employed throughout sales networks, and systems for the appropriate treatment of end-of-life batteries.

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.

Efficient use of resources

Automobiles

Continuation of design aimed for reducing materials

Among 3Rs, the first priority should be “Reducing (emission reduction)”. Under the policy of making parts Smaller, Fewer, Lighter, Shorter, and Neater, Suzuki is promoting reduction of emission by thoroughly reducing materials to be used and weight saving.
For example, in addition to front and rear bumpers and radiator grille, front and rear fender, splash guard, side sill splash guard, and front and rear door splash guard of XBEE launched in December 2017 have been slimmed.

Expanding adoption of thermoplastic resin parts

Recyclable design (automobile)

Recyclable vehicle design is an important factor to allow for easy recycling of end-of-life cars.
Suzuki always tries to produce eco-friendly vehicles by employing easy-to-recycle materials for exterior and interior resin parts.

Major components using recyclable resinous materials (example: exterior of new XBEE)

Use of easily recyclable resinous materials

Plastic is roughly divided into two types: “Thermoset resin”*1 and “Thermoplastic resin”*2.
By applying the thermoplastic resin to almost all plastic parts, Suzuki is promoting environmentally-friendly vehicle manufacturing.

Topics Suzuki received the Contribution Prize of the 49th Ichimura prizes in industry.
~ Development of resin material with superb appearance and application to pre-coloured interior parts ~

“Development of resin material with superb appearance and application to pre-coloured interior parts”, for which Suzuki received the award, was acknowledged because Suzuki had developed the resin material (polycarbonate) that provides the glossy appearance and durability against light, heat, and shock as the material for sections requiring particularly high quality from among other resin parts for automobiles. We also plasticised it for automobile interior parts by combining it with material colouring technology and structure design technology. While it is a technology for colouring materials, it creates a glossy and high-quality appearance equivalent to coating, and also contributes to a reduction of the environmental impact compared to normal coating, such as a reduction in the emissions of volatile organic compounds (VOC). Suzuki is expanding the application of this technology to interior parts, including the instrument panel garnish of Hustler and the audio garnish of WagonR.

[Structure of resin material with superb appearance]

∙ A clear resin material with high resistance against light, scratch, heat, impact, and other necessary performance parameters has been developed by compounding bio polycarbonate (bio PC), which is mainly made from plant-derived isosorbide, and special styrene-base rubber (Figure 1). This conforms to the new regulation for automobile interior parts, UN-R21. This material proves its worth as the base material of the technology for colouring materials that Suzuki has developed, and results in resin parts for the interior with excellent appearance without depending on coating.

*UN-R21: Legal standard that applies to the type approval for automobiles in order to protect occupants in cabin.

[Effects of resin material with superb appearance]

  • ∙ New decorative styles with various colours have been provided for instrument panels of automobiles which used to be black in most cases.
  • ∙ As a result of the elimination of coating, there is reduced emission of volatile organic compounds (VOC) included in paints (Figure 2), and cost savings have also been realised.

Continuation of design for reducing materials

Suzuki is trying to reduce the number of parts/materials and realise thinning, downsizing, etc. of parts in order to promote the effective use of resources.
For “BURGMAN 400 ABS” launched on 4 August 2017, we aimed to reduce the weight of materials by examining the number, size and structure of all exterior resin parts, including the seat. As a result, we have realised weight reduction of 7.7kg compared to the conventional model.

Expansion of adoption of thermoplastic resin parts

Suzuki is making efforts to incorporate recycling in the design and development of motorcycles.

We employed recycled in-mold resin material (PP) and recyclable in-mold resin material (PP) for GSX-R125 and GSX-S125.

*PP: Polypropylene

Usage of in-mold resin parts (PP) (example: GSX-R125) Usage of in-mold resin parts (PP) (example: GSX-S125)

Reduction exhaust gas

Catalyst technologies

It is indispensable to reduce emissions including when the engine is cold, in order to satisfy emission control regulations that are getting more stringent in all over the world. While reducing emissions from engines, we have been promoting improvement in performance of catalysts for exhaust-gas purification. We optimise the design of precious metal and rare earth used for catalysts, and concentrate precious metal effective for the performance of cold engines at the front section of the catalyst. Such zone-coated catalyst is adopted for strict emission control regulations in Japan, Europe, etc. In addition, we also adopt a thin-wall, high-cell-density catalyst excellent for purification of cold engines, hexagonal cell catalyst that performs excellent purification during high-speed driving, newly-developed catalyst that saves precious metal by highly dispersing iron and cerium in micro size etc. in order to clean exhaust gas all over the world.

Zone-coated catalyst

Motorcycles

Reducing exhaust gas

We are working on reinforcement of purifying performance as exhasut gas reduction technology to meet the 2016 exhaust gas restriction in Japan.

Improvement in catalyst (tandem honeycomb)

Tandem honeycom was adopted for the BURGMAN 400 ABS launched in August 2017. Purifying performance is reinforced by changing from the coventional single honeycomb to a tandem honeycom structure, in which two honeycombs are positioned inline with space in between the two honeycombs.

Outboard motors

Reducing exhaust gas

Suzuki four-stroke outboard motors satisfy the year 2008 emission regulation values set by California Air Resources Board (CARB), the secondary regulation values set by the U.S. Environmental Protection Agency (EPA), and the year 2011 marine engine emission voluntary regulation values (secondary regulation) set by Japan Marine Industry Association.

Reinforcement of environmental management

Management of substances of concern

Based on the IMDS (International Material Data System) we introduced in 2003, which is an automobile industry-related material data collection system, we have established an in-house management system concerning substances of concern (see the chart below). This system enables us to control not only the four heavy-metal substances (lead, mercury, hexavalent chromium, and cadmium) targeted by European ELV Directive, but also substances of very high concern (SVHC*) specified in the REACH regulation (Registration, Evaluation, Authorisation and Restriction of Chemicals). Also, recyclability for receiving type approval of motor vehicles in the European Union is calculated by using this system.
So far, we have identified compliance with laws and regulations related to substances of concern on all products produced by domestic plants and Magyar Suzuki Corporation Ltd. (Hungary), some products of Maruti Suzuki India Ltd. and Suzuki Motor (Thailand) Co., Ltd., and some motorcycles of P.T. Suzuki Indomobil Motor (Indonesia) by using this system. We are promoting introduction of IMDS globally, such as starting preparation for introducing IMDS to Suzuki Motorcycle India Private Limited. Through such efforts, we verified the compliance with laws and regulations related to substances of concern on additional 32 models of automobiles, motorcycles, and outboard motors in FY2017.
We will promote reduction management of substances of concern through applying the system for automobiles sold and motorcycles manufactured in India.

*SVHC: Substance of Very High Concern

IMDS training

Strengthening thorough prohibition of use of asbestos in Suzuki Group

The use of asbestos is thoroughly prohibited in Suzuki’s technical standards. Last year, we newly established the “Asbestos Control Rules” in order to further enhance prohibition of the use of asbestos. The rule requires establishing management rules of asbestos at our overseas production plants, announcing complete prohibition of use of asbestos to our business partners, and implementing periodical education to persons concerned in the company. Implementations of these requirements are audited by Suzuki.

Conformance to regulations concerning chemical substances

Shift to materials that do not contain decabromodiphenyl ether (DecaBDE: brominated flame retardants) specified as an additional abolition substance in the POPs Convention has completed by March 2018. We are also promoting the shift in European-specification products to materials that do not contain 4 substances of phthalate type plasticiser (DEHP, DBP, BBP, and DIBP) specified as a limited substance (prohibition) in REACH (EU) under cooperation with our suppliers.

Promotion of establishment of the system to control substances of concerns in overseas bases

As a pillar for management of substances of concerns, we established the "Suzuki Green Procurement Guideline” and are starting its operation accordingly at major overseas production bases since 2011. We have also started the audit aimed to check its operation.
Plus, we are promoting a scheduled introduction of the "Suzuki Green Procurement Guideline” to bases that have not started its operation.

Reducing VOC (Volatile Organic Compounds)*1 in Car Interior

In order to provide safe and secure products to customers, we are making efforts in reducing the amount of VOC by using materials, bonding agents, etc. that emit less VOC for interior parts. For all new domestic automobile models sold since January 2006, we have successfully achieved lower cabin VOC levels than the target set by the Ministry of Health, Labour and Welfare, which is deemed as the automobile industry’s voluntary goal*2. In FY2017, we achieved the target for the new Spacia, XBEE, Swift Hybrid, and Swift Sport.
In addition to reduction of VOC, we are making efforts in reducing cabin odour to promote making of more comfortable interior environment.

  • *1 VOC is deemed as a cause of sick building syndrome (bringing about a headache and/or sore throat) and is known as a danger substance to public health.
  • *2 Japan Automobile Manufacturers' Association (JAMA) takes a voluntary approach to reducing the vehicle cabin VOC on 13 different substances defined by Japan's Ministry of Health, Labour and Welfare by imposing its voluntary targets, all of which are stricter than the government targets, on new passenger car models marketed from April 2007 and new commercial vehicle models sold from April 2008.

Reducing noise

Automobiles

Vehicle exterior noise

We are trying to reduce noise generated from automobiles in order to solve road traffic noise which is one of environmental problems. As for concrete actions, we are reducing various kinds of noises from the noise source in an automobile such as the engine, transmission, air-intake and exhaust systems, and tyres. At the same time, we are optimising the design of the sound insulation cover that is used to prevent the inside noises from being released to the outside of vehicle.
We are taking actions for the vehicle exterior noise regulations in Japan and other countries on all automobiles manufactured and sold by Suzuki.
The company also meets the new exterior noise restriction (R51-03) introduced in October 2016 in Japan for all of our new models.

Major Noise Prevention Measures

Vehicle interior noise

Also, to provide comfort and quiet interior environment to users, we are promoting reduction of vehicle interior noise by improving noise sources and taking sound absorption, sound insulation, and vibration damping measures.

Motorcycles

Example of applied product

The following describes our noise reduction efforts, taking an example of GSX-R125 ABS.
To conform to the domestic noise regulation, while maintaining styling and output character, GSX-R125 ABS adopts a number of structures with high noise reduction.

For air cleaners, intake noise has been reduced by securing enough volume and placing a resonator in an outlet pipe.
Also by making its inner wall into a rib structure for securing rigidity, radiated sound from air cleaner wall is reduced.

As for mufflers, exhaust noise has been reduced by securing enough volume and making a structure with high noise reduction. Also, by placing glass wool inside the muffler wall, radiated sound from muffler wall is reduced and damping performance is improved.

Promotion of green procurement

We have established “Suzuki Green Procurement Guideline” that indicates our policy to purchase eco-friendly parts and materials from suppliers who agree to our guideline and submit “Suzuki Green Procurement Promotion Agreement” to us.
We partially revised this guideline in October 2013 to phrase the matter related to establishment of the substances of concern control system of partner companies, and prepared/added the self-check sheet for substances of concern control system. (We are requesting new and existing suppliers to submit check sheets thereafter. More than 50% of suppliers of production parts have attained outside certifications including ISO14001.)
Also, we are going hand-in-hand with our suppliers to conform to not only existing regulations, such as European ELV Directive and European Regulation concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), but also various future environmental laws and regulations.
