GLOBAL SUZUKI

In order to make sustainable growth, we are making efforts in business activities by having common value and interacting with the society. Various initiatives made in production and offices include: promoting reduction and control of CO2 emissions through promoting energy-saving activities and expanding the use of alternative energy; efficiently using resources such as recycling wastes (raw materials and office papers) and water; and preventing contamination by setting and managing restriction values higher than those required in laws and regulations for emission gas, wastewater, chemical substances, etc. emitted from plants.

Reduction in amount of CO2 emitted

Reduction of CO2 emission in manufacturing activity

CO2 emissions amount per global production units

The “Paris Agreement”, which is a new international framework aimed at reducing greenhouse gas to suppress 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 controlling the rise of 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 we are making efforts to reduce the amount of CO2 emissions per production unit (converted to the number of automobiles) of Suzuki’s global manufacturing units by 10% (against FY2010) by 2020 in accordance with the “Suzuki Environmental Plan 2020”.
The total amount of CO2 emissions from manufacturing activity in FY2019 of Suzuki’s global manufacturing units was 1,009,000 t•CO2/year (up by 16% compared to FY2010, and down by 3% compared to the previous fiscal year), that of Japan was 361,000 t•CO2/ year (down by 6% compared to FY2010 and by 5% compared to the previous fiscal year), and that of overseas was 648,000t•CO2/year (up by 34% compared to FY2010 and down by 2% compared to the previous fiscal year). The amount of CO2 emissions per production unit of all Suzuki’s global manufacturing units was 0.289 t•CO2/vehicle (down by 5% compared to FY2010 and up by 7% compared to the previous fiscal year), that of Japan was 0.367 t•CO2/vehicle (down by 5% compared to FY2010 and up by 1% compared to the previous fiscal year), and that of overseas was 0.258 t•CO2/vehicle (unchanged compared to FY2010 and up by 11% compared to the previous fiscal year).
CO2 emission amount per manufacturing unit in FY2018 exceeded the final FY2020 reduction target, but FY2019 could not achieve the target. Although some plants in Japan started switching from LPG to city gas, and solar power generators were expanded in overseas, decrease in global production units (down 10% from the previous year) worsened the energy efficiency. As for FY2020, the Company will further promote initiatives toward achieving the target such as by expanding the switch to city gas in domestic plants, high efficiency of air-conditioning, and expanding solar power generators in overseas.

Energy-saving activities at plant

Large energy-saving effects were acquired by switching from LPG to city gas at Osuka Plant, reducing defect within the cast process of Sagara Plant, and fixing air leakage in each plant.
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 utilizing 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 non-operating time.

Reduction of CO2 emission from non-manufacturing activity

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.

Partial adoption of automatic air conditioning control system installed with AI “Smart-DASH”

In FY2018, Smart DASH(R) was introduced in one floor of a data center and reduced power consumption by approximately 24.9%. The same system was also introduced in another floor of a data center.

Adoption of high-efficiency air conditioning facility “FMACS(R)-V hybrid (LL)”

One unit of FMACS(R)-V hybrid (LL) indirect outside air-cooling air conditioning system, which is said to reduce energy used for air conditioning in data center by up to 63%, was introduced. We plan to replace the present air conditioning system with FMACS(R)-V hybrid (LL).

Promotion of CO2 emission reduction at offices

We determined the standard of employee behavior 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 behavior on the in-house homepage so that individual employee can check the result of their activities.

Standard of employee behavior

We have established a standard of employee behavior (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 Behavior for In-house Cost Cutting Activities (Excerpt)]

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

Visualization of energy consumption specified in the standard of employee behavior

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 behavior 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.
By far, we changed up to approximately 80% of the light in offices to LED.

Introduction of LED lights

Other efforts

Reduction of moving within the company by utilizing IT

We are making in efforts in reducing energy consumption from moving within the company by proactively utilizing TV conference system, Web conference system, and remote work environment.
Total reduction of moving hours totaled approximately 3,000 hours/year.

Promotion of eco-driving

It was in FY2007 that we started the eco-drive education as part of our environmental education programs. And since FY2009, we have held special seminars focusing on eco-drive at the headquarters and each plant/office on an as needed basis. So far, 8,435 persons in total participated in the seminar.

Effective use of resources

Effective use of resources in production activities

Reduction of waste materials

Total waste discharge amount

The total waste discharge amount at Suzuki and domestic manufacturing subsidiaries was 124,000 tons (down 9% from the previous year), and the global total waste including Japan was 350,000 tons. Also, there are no exports/imports of hazardous wastes specified in the Basel Convention.

Reduction of landfill amount

While Suzuki continued the zero-level*1 landfill amount with 0.17t, domestic manufacturing subsidiaries did not achieve the zero-level landfill amount with 217t. Global landfill amount*2 was 597t (down 32% from the previous year). We plan to achieve zero-level of domestic manufacturing subsidiaries in FY2020 by reviewing their waste disposal method.

  • *1 Definition of the zero-level
    Plants and die plant in Japan: The total amount of landfill waste is less than 0.5% of the amount in FY1990 (24,675t).
    Domestic manufacturing subsidiaries: The total amount of landfill is less than 0.5% of the amount in FY2002 (1,370t).

Early disposal plan of PCB (Polychlorinated Biphenyl)

The Act on Special Measures concerning Promotion of Proper Treatment of PCB Wastes requires appropriately disposing of PCB wastes contained in old capacitors etc. by 31 March 2027. In order to completely dispose of PCB wastes now stored in house as soon as possible, Suzuki has made a waste disposal consignment contract with a waste disposer authorized by the Ministry of the Environment.
At Suzuki’s domestic plants, PCB wastes equivalent to 1,233 units of vehicles have been disposed by the end of March 2020.

Reduction of wastes from offices

Under the policy of making parts smaller, fewer, lighter, shorter, and neater, Suzuki is making efforts for paper reduction and material recycling.

Paper reduction

For the purpose of reducing the amount of paper used, Suzuki has been aggressively conducting company-wide paperless and paper reduction activities by promoting computerization of various documentary forms, duplex printing, use of backing paper, and reduction of documents used at meetings.

Promotion of material recycling of paper waste

At Suzuki head office, paper wastes were previously burnt for thermal recycling (reused as heat energy). Since July 2005, however, material recycling has been conducted, instead of the thermal recycling, through separate collection of office documents, newspapers and magazines, cardboard boxes, etc. In FY2019, 1,006 tons of paper wastes were recycled.

Efficient use of water resources in production activities

Reduction of amount of water used

Since FY2016, we have been working toward a target to reduce base unit amount of water used by 10% by FY2020, with FY2010 as the base year, and domestic production units (converted to the number of automobiles) as the base unit denominator. For this purpose, we are adopting airtight cooling towers, and utilizing air-cooled system and cooling water for compact air conditioners. At Maruti Suzuki India and Suzuki Motor Gujarat in India, where they have severe problem with water shortage in particular, they accomplished “zero” drainage discharge to outside by reusing wastewater for gardening in the company, while introducing air-cooling system for equipment to reduce use of water.
The amount of water used in FY2019 in Japan decreased by 0.7% compared to the previous year, resulting in 4.06 million m3, and base unit increased by 5.3% year-on-year from 3.92m3/unit to 4.13m3/unit.

Topics Reusing wastewater and reducing landfill waste at Suzuki Motor Gujarat

Protecting water resources through reusing wastewater

The state of Gujarat located in the northwestern part of India has a drying zone climate with few rains, and the state is facing shortage of water. To deal with water shortage issue, since its start of production in February 2017, Suzuki Motor Gujarat started initiatives to reuse wastewater from production processes as industrial water by purifying them through RO membrane filtering device. Reuse of wastewater from toilets started in May 2019, and from July 2019, up to 100% of wastewater is reused. From these efforts, use of new water amount in FY2019 was 1.0m3/unit.
Suzuki Motor Gujarat is contributing in protecting water resources by proactively making efforts for reusing wastewater.

Reduction in landfill waste

Various types of wastes are generated from automobile plants. Since its start of production in February 2017, Suzuki Motor Gujarat has contracted with cement company to recycle paint residue generated from painting process, which is regarded as hazardous wastes in the Indian law, and sludges generated from wastewater treatment into cement materials. All other wastes were treated as landfill wastes, but from April 2019, large amount of those wastes are being switched to recycling to reduce landfill waste.

Cement company truck loading wastewater treatment sludge

Thorough water-saving at offices and employee dormitories

In order to aggressively reduce water usage, we are making efforts in awareness of water-saving such as by announcing detailed measures, in addition to posting water-saving awareness posters in toilets and kitchens. We are also making efforts in reducing water usage such as by automating faucets and introducing water-saving models in toilets.

Efforts for environmental conservation

Control of chemical substances

Purchasing new substances

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

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

PRTR (Pollutant Release and Transfer Register) targeted substances

To reduce materials with environmental impact, we are working to reduce PRTR targeted substances.
The amount of emissions and transportation of them was 1,295 tons in FY2019.

Control of water and soil contamination

Preventing the leakage of sewage

For the purpose of water quality management and maintenance, our analysis department periodically conducts analysis on plant effluent, groundwater, water used in factory processes, and industrial water to check the possibility of sewage leaking from any plant. If any abnormality should be found in the water quality, the relevant section will be immediately informed, and proper measures will be systematically carried out.
We were registered as the “Environmental Measurement Certification Business (Concentration)” of the Measurement Act in 1994. Since then, we have continued to conduct field measurements and verify the measured industrial wastewater/wastes, while promoting the group-wide activities for prevention of contaminant outflow.

Analysis

Soil and groundwater protection

Efforts for prevention of the proliferation of soil contamination

From FY2015 to FY2016, all 16 facilities in our domestic plants and domestic manufacturing subsidiaries investigated geography and history in order to record the information about risks of soil contamination due to chemical substances etc. used in the past. Based on this investigation, upon making changes to character of land with risk of soil contamination, we conduct soil survey, and are making efforts in purifying and removing contamination appropriately when soil contamination is found.
In FY2019, we conducted soil survey 3 times in our domestic plants, and 2 soil contamination was found. Soil contamination was appropriately sanitized and removed by excavation and removal, and sanitizing the area.

Efforts for cleanup of groundwater

Since the organic chlorine compounds (trichloroethylene and cis-1, 2-dichloroethylen) were discovered in the groundwater at Takatsuka Plant in January 1999, we have continued the groundwater cleanup efforts and have conducted measurements along the plant’s site boundaries. In addition, we started a biological remediation in March 2015 for groundwater cleanup by using microorganisms to complete the sanitization as early as possible. Groundwater is being cleaned up owing to the effect of this bio-remediation. We will aim to complete the cleanup of organic chlorine compounds by continuing the bio-remediation.

Reduction of odor and noise

Although we strictly follow the relevant regulations or laws, the odor and noise released from our plants may make local residents uncomfortable. Compliance with the laws and regulations is the minimum required CSR (corporate social responsibility). Aiming to be fully trusted by the local community, we will continuously promote necessary measures for prevention of noise and odor and elimination of their potential sources.
