    Preventing Soil/Groundwater Pollution

    In addition to conforming to each country’s and territory’s legislation relating to the prevention of soil pollution, the Teijin Group formulated guidelines for preventing soil and groundwater pollution. Under these guidelines, we are striving to prevent soil and groundwater pollution resulting from our business operations.

    Current Status of ISO 14001 Certification

    As a mechanism to minimize its impact on the environment, the Teijin Group encourages its business sites and plants to obtain the ISO 14001 certification, an international standard related to environmental management, as well as the Eco Action 21 recommended by Japan’s Ministry of the Environment.


  • Climate Change Initiatives

    Reducing Greenhouse Gases Emitted During Manufacturing

    Targets for FY2012-2020

    Group target
    Achieve a CO2 emissions reduction ratio of 1% or more per year (compared to the level in the base year in FY2011).
    Target for Japan
    Reduce CO2 emissions by 20% or more compared to the FY1990 level by FY2020.

    The Teijin Group is working to reduce its greenhouse gas emissions released during manufacturing. In FY2016, we decreased CO2 emissions by a fuel conversion of in-house power generation equipment at the Mishima Factory of Toho Tenax Co., Ltd. In addition, the impact of the shutdown of the Singapore plant has been a reduction of CO2 emissions. The Teijin Group's overall CO2 emissions decreased16% compared to FY2015. 

    In Japan, CO2 emissions were 0.82 million tons (a 21% decrease from FY2015) owing to active promotion of energy-saving projects such as the reduction of energy loss in each business. Overseas, CO2 emissions were 0.70 million tons (a 9% decrease from FY2015)

    • Includes CO2, methane and nitrous oxide.
    • CO2 emissions are calculated according to the coefficients specified in the Law Concerning the Promotion of Measures to Cope with Global Warming. (Up to fiscal 2014, an emissions coefficient for electricity of 0.555 kg CO2 /kWh was used; in fiscal 2015, 0.579 kg CO2 /kWh was used. In fiscal 2016, in Japan the post-adjustment emissions coefficient by an electric power supply company was used; overseas an IEA-announced country-specific emissions coefficient was used (2014 values).) However, for power purchased overseas, where known, the relevant emissions coefficient is used for the calculations. We deduct an amount of CO2 emissions corresponding to the amount of energy sold to other companies.

    Reducing CO2 Emissions Associated with Use of Company Vehicles

    In Japan, the Teijin Group set independent numerical reduction targets by business site for CO2 emissions associated with the use of company vehicles. Common measures include updating vehicles used for sales activities to eco-cars and recommending fuel-efficient driving.

    These measures have achieved a reduction in CO2 emissions per distance traveled.

    As a result, total CO2 emissions related to the use of company vehicles in FY2016 were 7,221 tonsa red star(3% reduction compared to FY2015).

    Reducing CO2 Emissions in Logistics

    CO2 emissions in the logistics field were 9,755 tons in FY2016, a decrease of 1,863 tons from FY2015. This was primarily due to the decreased domestic shipment volumes in the high-performance fiber business as a result of structural reform, a scaling down of our domestic raw materials and polymerization business, as well as the streamlining of transportation in the resin business through the promotion of collective transportation.
    However, this represents a 9.9% worsening of our CO2 emissions per unit.
    This was because, despite an improvement in emissions per unit due to the introduction of “hub and spokes” in the resin business, there was a significant decrease in transportation volumes for the raw materials and polymerization business, which has high transportation efficiency (77% decrease compared to FY2015), therefore the Teijin Group’s overall emissions per unit worsened relatively. Other factors were the rise of small-lot transport ratio and fall in collective transport ratio in the high-performance fiber business and film business. Benchmarking the volume of CO2 emissions per 1,000 ton-kilometers in FY2011 as 1, the indexed volume of CO2 emissions was 1.088.
    In FY2017, with the goal of completing structural reforms, Teijin will cease operations of multiple Japanese plants and transfer production overseas. This is expected to result in a reduction of CO2 emissions, however it will also increase shipments of imported products therefore utilization of ports in close proximity to customers will be promoted. Furthermore, we will continue to increase collective transport for the transporting of products from domestic production bases and promote a shift in transport methods towards environment-focused rail freight and RORO shipping with the aim of reducing the emissions per unit itself.

    • Until FY2013, the scope for calculating CO2 emitted by logistics comprised Teijin Limited (excluding the aramid fiber business), Teijin DuPont Films Japan Limited (present day Teijin Film Solutions Ltd.), and the former Teijin Fiber Co., Ltd.'s apparel business that was consolidated with Teijin Frontier Co., Ltd. From FY2014, Teijin Limited's aramid fiber business, Teijin Pharma Limited, and Toho Tenax Co., Ltd. were added to the scope. From FY2015, Teijin Cordley Limited was added to the scope.
    • The maximum load and fuel consumption per ton-kilometer of certain vehicles were revised in FY2014.

    Efforts to Reduce CO2 Emissions from Offices

    We are taking measures to improve the efficiency of energy use at the Osaka head office (company-owned building), group company head offices, sales branches and other business sites. A particular measure in summer/winter, besides encouraging suitable operation of office air-conditioning, is the Teijin Cool Biz/Warm Biz initiative, which encourages clothing appropriate for the season (dress code) to facilitate less power consumption and comfortable office environments.

    As a result of implementing these activities, the total CO2 emitted was 12 kilotonsa red star in FY2016 (a 9% reduction compared to FY2015) .

  • Reducing Chemical Substance Emissions

    Chemical Substance Emission Reduction Results

    Targets for FY2012-2020

    Group target
    Reduce chemical substance emissions by 80% or more compared to the FY1998 level by FY2020.

    The Teijin Group is actively committed to reducing emissions of all chemical substances listed as Class 1 chemical substances in the Chemical Substances Management Law* revised in April 2010 (462 substances), and those specified by the Japan Chemical Industry Association (433 substances). Excluding duplicated listings, there are 575 specified chemical substances.

    FY2016 emissions of targeted chemical substances into the environment were 1,453 tons, a 26% decrease from FY2015. In Japan, we achieved a 4% year-on-year decrease, and overseas a 65% year-on-year decrease compared to FY2015, partially due to a scaling down of some businesses.

    In FY2016, of the total chemical substances emitted into the environment, 98.5% was released into the atmosphere, 1.5% into the water, while there were no emissions into landfill or the soil.

    Emissions of volatile organic compounds (VOCs) were 1,373 tons (a 29% year-on-year decrease).

    Impact Due to Water Usage and Wastewater and Impact on Atmosphere

    The Teijin Group uses freshwater (industrial water, groundwater, and tap water) as well as seawater, primarily for cooling. The Group is working to reduce the impact from its overall use and discharge of water. In FY2016, freshwater consumption amounted to 77 million tons, a decrease of 8% compared to FY2015. Seawater consumption amounted to 20 million tons, a decrease of 48% compared to FY2015. As a result of Group-wide efforts to reduce waste water, the total amount of water discharged by the Teijin Group decreased by 19% year on year to 90 million tons in FY2016.

    The total amount of load associated with water discharge (calculated from chemical oxygen demand (COD) and biochemical oxygen demand (BOD)) was 421 tons (a 29% decrease from FY2015).

    SOx emissions resulting from fuel use in FY2016 were 2.6 kilotons (a 14% decrease from FY2015). NOx emissions generated in the same manner were 1.8 kilotons (a 14% decrease from FY2015).

    Reduction of "Waste with No Effective Use" (Waste Incinerated without heat recovery or Put into Landfill)

    Target for FY2020

    Group target
    Reduce “waste with no effective use” by 85% or more compared to the FY1998 level by FY2020.

    The Teijin Group is committed to reducing the amount of waste it generates, as well as to reducing "waste with no effective use" through promoting a shift to reusing and recycling based on material, chemical or thermal processing.

    In FY2016, we generated 4.1 kilotons of "waste with no effective use" (6.2% of the total 66 kilotons a red star of waste discharged).

    The amount of “waste with no effective use” in FY2016 was increasing due to temporary factors such as the launching of new production lines.

    • In FY2012, in addition to the 4,149 tons shown in the graph above, 7,862 tons of sludge was generated as a result of dredging a discharge reservoir and was put into landfill at an external site

    Improvements through Using Waste per Unit of Production as an Indicator

    The Teijin Group has defined zero emissions as reducing the ratio of "waste with no effective use" to 1% or less of the total waste generated.

    In Japan, all factories that produce 500 tons or more of waste per year achieved zero emissions by FY2011. 

    Starting from FY2012, our target for our entire group has been to reduce the total waste discharged per unit of production amount by 1% compared to the previous fiscal year.

  • Biodiversity Conservation

    Basic perspective and aims regarding biodiversity

    As a partner in promoting Keidanren´s (Japan Business Federation) Declaration on Biodiversity, the Teijin Group is developing activities in line with these action guidelines. The basic concept underlying our initiatives is as follows.

    1. Promote sustainable management actively

    Promote sustainable management based on recognition of the fact that biodiversity is critically important to preserving and reducing impact on the global environment.

    2. Encourage full participation of all employees

    Increase employees´ awareness and understanding of biodiversity and support voluntary activities relating to biodiversity.

    3. Build strong bonds with society

    Through communication and cooperation with local communities, express a high priority on the relationship between local residents and the environment.

    Biodiversity Conservation

    We are a promotion partner of the Keidanren (Japan Business Federation) Declaration of Biodiversity and are actively working to preserve biodiversity.

    To visualize the effect that factors such as chemical substances, greenhouse gases and waste emitted through business activities have on biodiversity, the Teijin Group has created the "Map of risks relating to loss of biodiversity due to business activities and activities to conserve biodiversity." This helps our employees to gain a clear awareness of the impact of business activities on biodiversity, helping to propel conservation activities forward.

    Moreover, the Teijin Group has contributed to the establishment of the Guideline for the Quantitative Appraisal and Assessment of Environmental Impact in order to perform hot-spot analysis which will identify priority issues for the company. The guideline is disclosed on the Japanese Business Initiative for Biodiversity (JBIB) website.

    Map of Risks (Biodiversity Loss Due to Business Activities) and Initiatives (Biodiversity Conservation)

    Biological Field Studies Using the Japanese Business Initiative for Biodiversity's Monitoring Sheet

    Both Teijin Limited's Matsuyama Factory and the Iwakuni Factory utilize the Japanese Business Initiative for Biodiversity (JBIB)'s "Plants & Wildlife Monitoring Sheet" for employees and outside experts to conduct surveys of flora and fauna and, through this process, check the level of contribution to biodiversity at each business site.

    At Teijin Limited's Matsuyama Factory, in May 2015, 10 employees and external experts conducted a biological field study. As a result of investigating bird and insect life at three locations within the factory and a nearby greenbelt, numerous life forms were observed. The high potential of the factory in terms of preserving biodiversity was recognized particularly due to the observation of four specifies of heron breeding colonies, a Japanese nightingale and an anax parthenope dragonfly.

    The factory has a 60-year history, and some of the groves within the grounds had trees that had grown taller than 15 meters. The survey also discovered that some of the groves had trees of a layered structure and as such, were growing outwards.

    Both business sites will continue to conduct regular surveys and exert effort for environmental preservation in order to continue contributing to biodiversity.
