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 effects 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 realise the target of controlling the rise of global average temperature to “less than 2°C”.
Suzuki has checked its global CO2 emissions, including those of our subsidiaries, in order to reduce the effects of greenhouse gas generated from our business operations. The ratio of emissions from our overseas production bases is 55.5%, more than a half of the entire global emissions (FY2017). In addition, when categorising the emissions according to source, such as from the plant and places other than the plant (experiment facilities, offices, sales distributors, etc.), emissions from the plants accounted for 89.0% of the total (FY2017).
Therefore, 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) at Suzuki Group’s manufacturing companies in Japan and overseas by 10% (against FY2010) by 2020 in accordance with the “Suzuki Environmental Plan 2020”.
The total amount of CO2 emissions in FY2017 from all Suzuki Group manufacturing companies was 1,054,000 t•CO2/year (up by 17% compared to FY2010, and by 8% compared to the previous fiscal year), that from Suzuki Group’s manufacturing companies in Japan was 401,000 t•CO2/year (up by 4% compared to FY2010 and by 6% compared to the previous fiscal year), and that from overseas manufacturing companies was 653,000 t•CO2/year (up by 26% compared to FY2010 and by 10% compared to the previous fiscal year). The amount of CO2 emissions per production unit of all Suzuki Group’s manufacturing companies was 0.290 t•CO2/vehicle (down by 8% compared to FY2010 and by 5% compared to the previous fiscal year). That of Suzuki Group’s manufacturing companies in Japan was 0.396 t•CO2/vehicle (up by 1.9% compared to FY2010 and down by 6.7% compared to the previous fiscal year), and that of overseas manufacturing companies was 0.249 t•CO2/vehicle (down by 10.0% compared to FY2010 and by 3.8% compared to the previous fiscal year).
Solar power-generation equipment was installed in Japan in 2015. Since then, we have changed the calculation method and reviewed CO2 emissions by subtracting the portion equivalent to sold electricity from the amount of CO2 emissions, considering said portion to be contribution to reduction of CO2 emissions. We will continue to promote energy-saving and the introduction of solar energy power-generation systems and will continue to make efforts to reduce CO2 emissions.

Energy-saving activities at plant

Large energy-saving effects were acquired by remodeling various processes according to production volume, such as reduction of pre-painting process into a single line at Kosai Plant, reduction of machine downtime rate per operation in the cast process of Osuka Plant, and reduction of defect within the cast process of Sagara 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 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 non-operating time.
CO2 reduction amornt of domestic plants and reduction amount by activities are as per below.

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, installing one wind force power generation system in a training center and solar power generation system at a site next to Sagara Plant, Maisaka, root-top of Hamamatsu Plant, Maruti Suzuki, and Pak Suzuki.
We will actively promote use of alternative energies, 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. Integration rate as of the end of FY2017 was 96.23%
We will conduct this measure continuously.

Shift to highly efficient air-conditioning system … Energy saving by approximately 18.23%

Recently, there has been significant technical progress and changes to efficiency improvement for air-conditioning systems in the data center, and energy savings can now be realised simply by replacing air-conditioning systems, even though the operation environment and handling conditions remain the same. We replaced two old-type reheat air-conditioning systems, which had reached the end of their service lives, to the inverter-type highly efficient all-year cooling air-conditioning system (FMACS(R)-V) in FY2017. As a result, power consumption was reduced by 18.23% per system.
We are planning to replace four reheat air-conditioning systems to FMACS(R)-V in FY2018.

*FMACS is the registered trademark of NTT Facilities.

Automation of control for the effective operation of air-conditioning systems

The operation of the air-conditioning system and temperature settings was conducted by the staff in accordance with their intuitions and experience. However, we investigated various solutions in order to realise automatic and effective operation of the air-conditioning system that does not depend on skill levels or manual intervention.
From the results of our trial calculations, we found that the energy required for air conditioning would be reduced by 10–15%. This will be adopted in FY2018.

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 use solar power and exhaust heat 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.

Standard of employee behaviour

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)]

  • Follow the predetermined temperature settings of air conditioner (cooling at 28°C and warming at 20°C).
  • Turn off unnecessary electric lights.
  • Save electricity of electric appliances.
  • Implement eco-drive.
  • 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 FY2017.

Introduction of LED lights

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 focussing on eco-drive at the headquarters and each plant/office on an as needed basis. So far, 5,818 persons in total participated in the seminar.

Effective use of resources

Effective use of resources in production activities

Flow of wastes etc.* (Unit: 1,000 t/year)

Reduction of waste materials

Total waste discharge amount

The total waste discharge amount at Suzuki plants and group manufacturing companies in Japan was 137,000 tons (up 23% from the previous year), and the global total waste*1 including Japan was 371,000 tons. Also, there are no exports/imports of hazardous wastes specified in the Basel Convention.

*1 The waste related data of major overseas plants have been publicised since FY2013.

Transition of total waste discharge amount at major plants in Japan and overseas

Reduction of landfill amount

The amounts of landfill of wastes from Suzuki plants and group manufacturing companies plants in Japan are 0t, both of which consecutively indicate the zero level*1. The global quantity of landfill*2 (including Japan) was 253t (up 315% from the previous year). Also, in Maruti Suzuki India, wastewater treatment sludge and other wastes from the plants used to be kept at a managed landfill within the company’s premises according to the India’s waste disposal law. But from 2010, as a result of making efforts in making sludge and other wastes into cement materials, landfill keeping ended with 324t of landfill as the final waste in FY2013. Zero landfill has been continued since FY2014, and wastes kept from the past are gradually sent to cement company. As for domestic group manufacturing companies, as a result of promoting recycling such as making into cement materials, we were able to make landfill amount to 0t, with landfill of 0.04t in FY2015 as the final amount.

Transition of landfill amount at major plants in Japan and overseas

  • *1 Definition of the zero level
    Plants and die plant in Japan: The total amount of landfill is less than 1% of the amount in 1990 (24,675t).
    Group manufacturing plants in Japan: The total amount of landfill is less than 1% of the amount in 2002 (1,370t).
  • *2 Data of major overseas plants is provided for FY2013 and later.
  • *3 Since FY2017, due to start of production at Suzuki Motor Gujarat Private Limited, general wastes from the company has been trated as landfill by local treatment company according to the local law.

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 authorised by the Ministry of the Environment. At Suzuki’s domestic plants, PCB wastes equivalent to 557 units of vehicles have been disposed by the end of March 2018.

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 computerisation 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 FY2017, 891 tons of paper wastes were recycled.

Efficient use of water resources in production activities

Reduction of amount of water used

Previously, we had not been setting reduction target for amount of water used, but since FY2016, we made a target to reduce base unit amount of water used by 10% by FY2020, with FY2010 as the base year, and global production units (converted to the number of automobiles) as the base unit denominator.
For this purpose, we are adopting airtight cooling towers, and utilising 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 by Suzuki and group manufacturing companies in FY2017 in Japan increased by 2.7% compared to the previous year, resulting in 4.34 million m3, but base unit decreased by 9.3% year-on-year from 4.72m3/unit to 4.28m3/unit.

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 behaviour, hazards, and handling cautions, etc. of chemical substances

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 FY1994. 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 group manufacturing companies 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 FY2017, we conducted soil survey 5 times in plants in Japan, and one soil contamination was found. Soil contamination was appropriately treated by excavation and removal.

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 of 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 sanitisation 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 odour and noise

Although we strictly follow the relevant regulations or laws, the odour 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 odour and elimination of the potential sources of them.
