    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 FY2017, we decreased CO2 emissions by a fuel conversion of in-house power generation equipment at the Mishima Factory as well as the shutdown of the Tokuyama Factory and cessation of production at the Gifu Factory. Consequently, the Teijin Group's overall CO2 emissions decreased 7% compared to FY2016. 

    Domestically, in addition to the above factors, CO2 emissions were 0.69 million tons (a 16% decrease from FY2016) owing to the active promotion of energy-saving projects such as the reduction of energy loss in each business. Meanwhile, our overseas operations recorded CO2 emissions of 0.72 million tons (a 3% increase from FY2016) due to increased production volume.

In group, 6.2% decrease compared to FY2011.

    • 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.)
      From FY2016 onwards, adjusted emissions coefficients of individual electric power companies are used for power purchased in Japan, and latest available IEA country-specific emissions coefficients are used for power purchased overseas. However, for power purchased overseas, where known, power company-specific emissions coefficients are 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 FY2017 were 6,899 tonsa red star (4% reduction compared to FY2016).

    Reducing CO2 Emissions in Logistics

    CO2 emissions in the logistics field were 8,981 tons in FY2017, a decrease of 774 tons from FY2016. This was primarily due to the decreased domestic shipment volumes by Teijin Film Solutions and in the high-performance fiber business as a result of structural reform, which led to cessations in production at multiple domestic plants, and the overseas relocation of production.

    However, this represents a 1.0% 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 and the expansion of goods transported by JR to the film business, there was a worsening in the transportation base unit in line with a decrease in transportation via sea freight and JR (rail) (down 4% compared to FY2016), and an increase in vehicle transportation (up 4% compared to FY2016). Benchmarking the volume of CO2 emissions per 1,000 ton-kilometers in FY2011 as 1, the indexed volume of CO2 emissions was 1.101.

    After the completion of structural reforms in FY2018, we predict further reduction of CO2 emissions, however this will coincide with an increase in shipments of imported products, therefore the 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.

    • Until FY2013, the scope for calculating CO2 emitted by logistics comprised Teijin Limited (excluding the aramid fiber business), 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 has been included in the scope, with the further addition of Teijin Engineering Ltd. in FY2017. Also, in FY2017, the manufacturing division of former Teijin Fiber was transferred and integrated into Teijin Frontier.
    • 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 Teijin Limited, 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.

    In FY2017, the total CO2 emitted was 6,899 tonsa red star (a 42% reduction compared to FY2016) due to closure of the Infocom Yokohama Data Center as well as relocation of our Osaka head office to a building with high energy-saving capabilities.

  • 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, which has increased to 567 substances after including the 105 voluntary-survey chemical substances specified by the Japan Chemical Industry Association.

    FY2017 emissions of targeted chemical substances into the environment were 1,808 tons, a 24% increase compared to FY2016. The reason for the increase is due to increased production volume in factories using large amounts of chemical substances, etc. The increase compared to FY2016 was 28% within Japan and 7% overseas.

    In FY2017, of the total chemical substances emitted into the environment, 98.9% was released into the atmosphere, 1.1% into the water, while there were no emissions into landfill or the soil.

    Emissions of volatile organic compounds (VOCs) were 1,721 tons (a 25% increase compared to FY2016) due to increased production volume.

    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 FY2017, freshwater consumption amounted to 73 million tons, a decrease of 5% compared to FY2016. There was no seawater usage due to the closure of plants that previously used seawater. As a result of eliminating seawater discharge combined with group-wide efforts to reduce waste water, the total amount of water discharged by the Teijin Group decreased by 24% year on year to 68 million tons in FY2017.

    The total amount of load associated with water discharge (calculated from chemical oxygen demand (COD) and biochemical oxygen demand (BOD)) was 410 tons (a 3% decrease from FY2016).

    SOx emissions resulting from fuel use in FY2017 were 2.2 kilotons (a 14% decrease from FY2016). NOx emissions generated in the same manner were 1.8 kilotons (a 1% increase from FY2016).

    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 FY2017, we generated 3.9 kilotonsa red star of "waste with no effective use" (6.8% of the total 58 kilotonsa red star of waste discharged). The amount of “waste with no effective use” in FY2016 increased due to temporary factors such as the launching of new production lines, but decreased in FY2017.

    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.
