Initiatives for Freon

Converting to refrigerant with low global warming potential

Since HFC-134a refrigerant currently used in car air-conditioners has a high global warming potential, we are now developing a next-generation air-conditioning system using an environmentally-friendly HFO-1234yf refrigerant that has an extremely low global warming potential. We are also promoting to introduce models that meet restrictions of air-conditioning refrigerant of each country and region. In FY2019, the new Hustler was launched in Japan by installing HFO-1234yf refrigerant air-conditioning.

Topics Newly-developed ultrasonic welder AUH30CW won the Eco-Friendly Award

The newly-developed ultrasonic welder AUH30CW was exhibited at the JAPAN PACK 2019 (Japan Packaging & Manufacturing Technology Show 2019) held in 29 October at the Makuhari Messe (Chiba Prefecture). It received the Eco-Friendly Award for its compact design and economy including its performance in largely saving electricity since it is not necessary to pre-heat the device.
AUH30CW is an industrial machine that enables quick and easy welding of materials such as plastic and vinyl by using friction heat from ultrasonic vibration. It can be used in various usages including blister pack, food pack, non-woven fabric, and thin resin parts with safe, and simple welding operation. At the exhibition, the machine was highlighted by wide range of industries including packing and food machine manufacturers.

Efficient use of resources


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, front grille and front fender lining, front and rear fender splash guards and side sill splash guard of Hustler launched in January 2020 have been slimmed.

Adopting plant-derived resin (bio polycarbonate)

Suzuki is adopting bio polycarbonate resin (bio PC), in which its main material is plant-derived isosorbide. Bio PC produces great color and by coloring the resin material, it creates appearance equivalent to painted resin, thereby enabling reduction of CO2 and VOC by abolishing painting process.
Bio PC was first adopted for the interior color panel of Hustler launched in 2014, and since then, it has been adopted on interior parts of Alto Lapin, Spacia, WagonR, Jimny, Swift, and XBEE. With the Bio PC adopted on Hustler as its first generation, the second generation with improved shock resistance, and the third generation with improved shock resistance and appearance were developed and expanded the models using them. They were adopted again on interior parts of the second-generation Hustler launched in January 2020, and the total amount used in all models per year amounts to 200t.
Suzuki will continue to expand the adoption of bio PC by using these materials and technologies for forming and molding pre-colored resin materials.

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.

Efforts for environmental conservation


Calculation of emissions of air-polluting substances of products using Life Cycle Assessment (LCA)

Suzuki is promoting to reduce environmental load throughout the life cycle by calculating LCA of not only CO2 but also of air-polluting substances other than CO2.
Through promoting electrification, weight reduction, and increase in thermal efficiency of engines, they especially contribute to reduction of air-polluting substances during the running stage.

Suzuki LCA Stages

Ratio of emission amount of air-polluting substance (%)

Control of air pollution


Reduction of hazardous elements within exhaust gas

In order to satisfy emission control regulations that are getting more stringent in all over the world, while improving combustion technologies of engines, we have been promoting improvement in performance of exhaust-gas purification. Also, from the view of preserving resources, we are making efforts in reduction of precious metals and rare earth used for catalyst.
We are making efforts for cleaning emission gas throughout the world by adopting purification technologies that meet each market needs such as zone-coated catalyst which concentrates precious metal effective for the purification performance in cold engine start at the front section of the catalyst, newly-developed catalyst that suppresses heat deterioration, and gasoline particulate filter (GPF) which takes out PM (particulate matter) of direct-injection turbo engines.

Suppresses heat deterioration of palladium (Pd), which excels in purification performance, by highly dispersing iron (Fe) and cerium (Ce) oxides in micro size

Topics Maruti Suzuki introduced India’s first BS6*1-compliant light commercial vehicle,Super Carry S-CNG*2

On 22 May 2020, Maruti Suzuki launched the CNG variant of a light truck, Super Carry S-CNG. Installed with dual ECU and intelligent injection system, Super Carry S-CNG is the first light commercial vehicle in India to comply with BS6 restriction.
In the recent years, India is encountering air pollution concerns due to such causes as global warming and PM2.5 in urban areas. Fuel of CNG is natural gas, which is mainly composed of methane (CH4) that emits less CO2 and NOx during combustion compared to oil and coal*3, so it is expected to suppress expansion of global warming and air pollution.
As of September 2020, Maruti Suzuki offers CNG variants on 7 models other than Super Carry, including Alto, WagonR, and S-PRESSO.

  • *1 BS6 (Bharat Stage 6): Emission gas restriction introduced in India in April 2020, which is equivalent to Euro6 emission gas restriction of Europe.

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.

Meeting substances of concern

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. Using this system, we are conducting management as well as calculation of recyclability for receiving type approval of motor vehicles in the European Union, of not only the four heavy-metal substances (lead, mercury, hexavalent chromium, and cadmium) targeted by European ELV Directive, but also restricted substances specified in the regulations such as REACH regulation (Registration, Evaluation, Authorization and Restriction of Chemicals). We verified the compliance with laws and regulations related to substances of concern on additional 25 models of automobiles and motorcycles in FY2019. Also, by utilizing the in-house system called the SIDIS (Suzuki IMDS Data Inhouse System) renewed in the previous year, the above operations are operated more efficiently to swiftly meet fast changing regulations for substances of concern. SIDIS is also used independently by Maruti Suzuki, and from FY2019, management of IMDS started in India.
We will promote reduction management of substances of concern through applying the system for products manufactured not only in Japan, but also in overseas including Hungary, India, and Thailand.

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 are also implementing 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 (FY2019 result: 3 bases).

Strengthening thorough prohibition of use of asbestos in Suzuki Group

The use of asbestos is thoroughly prohibited in Suzuki’s technical standards. Especially, to enforce prohibition of use for parts delivered in overseas plants, we newly established the “Asbestos Control Rules”. 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 (FY2019 result: 4 bases).

Conformance to regulations concerning chemical substances

We are promoting the shift in products to materials that do not contain 4 substances of phthalate type plasticizer (DEHP, DBP, BBP, and DIBP) specified as a limited substance (prohibition) in REACH (EU), as well as PFOA (fluorine compound) prohibited in the POPs under cooperation with our suppliers. We completed to meet the labels in line with the international GHS (Globally Harmonized System of Classification and Labelling of Chemicals) system in 18 countries and regions including Japan (EU is counted as one region), and we also started providing SDS (Safety Data Sheet) on the company homepage (

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 automobile industry*2. In FY2019, we achieved the target for 7 models including the new Hustler and the minor-changed Ignis.
In addition to reduction of VOC, we are making efforts in reducing cabin odor to promote making of more comfortable interior environment.

Models achieving better values than the cabin VOC concentration guideline values in FY2019

  • *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 substances defined by Japan's Ministry of Health, Labor and Welfare in 2002 by imposing its voluntary targets, all of which are stricter than the government targets, on new passenger car models sold from April 2007 and new commercial vehicle models sold from April 2008.

Reducing noise


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 tires. At the same time, we are optimizing 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.


Suzuki motorcycles meet noise regulations such as 2016 regulation of Japan, UNR41-04 of Europe, and 40 CFR Part205 of the United States.

Example of applied product

The following describes our noise reduction efforts, taking an example of KATANA.
To conform to the latest domestic noise regulation, KATANA adopts a structure with high noise reduction, while designing to keep it within a minimum weight increase.

For air cleaners, the upper case has a rib structure for securing rigidity. Also, separators are placed within the tunnels leading to both sides of intake to increase damping performance of intake noise.

As for mufflers, they are made of main silencer and sub silencer, both placing glass wool inside the muffler wall, to reduce radiated sound and increase damping performance.

Promotion of environment conservation with our business partners

Understanding situation of CO2 emissions and information on water risks of our business partners (Japan)

Since 2016, Suzuki has been conducting research on information regarding climate changes and water risks of our domestic business partners with high purchasing amount. Through the research, we are making efforts in understanding their trends in CO2 emissions and water consumption amount, and situations of CO2 reduction target and water risk evaluation.
In FY2019, 112 companies of our business partners, which account for approximately 73% of our domestic purchasing mount, have cooperated to the research. Of these companies, those setting CO2 reduction targets for climate changes accounted for 86%, those evaluating physical risks including overflow and drought within the company for water risks were 81%, and those evaluating restriction and reputation risks concerning restrictions for water usage and company reputations were 74%. We will continue making efforts in the research while expanding it to overseas business partners as well.

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 92% 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, Authorization and Restriction of Chemicals (REACH), but also various future environmental laws and regulations.

* Suzuki Green Procurement Guideline:
