    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 striving to reduce the amount of greenhouse gasses emitted by its manufacturing activities around the world. In FY2014, the Group's CO2 emissions were 1.79 million tons, a 9% reduction in greenhouse gases from FY2013.

    In Japan, CO2 emissions were 1.04 million tons (a 14% decrease from FY2013) owing to active promotion of energy-saving projects such as the reduction of energy loss in each business.

    Overseas, CO2 emission were 0.76 million tons, about the same amount as in FY2013.

    • Includes CO2, methane and nitrous oxide.
    • Calorific values and CO2 emissions are calculated according to the coefficient specified in the Act on Promotion of Global Warming Countermeasures (an emissions factor for electricity of 0.555 kg-CO2/kWh is used for every fiscal year). For power purchased overseas, where known, the relevant emissions factor is used for calculations.

    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 FY2014 were 7,549 tons (4% reduction compared to FY2013) a red star.

    Reducing CO2 Emissions in Logistics

    In logistics, CO2 emissions intensity improved 3.3% year on year in comparison to an annual target for reducing CO2 emissions per unit volume of transportation by 1% or more. This was primarily attributable to the expanded use of Japanese domestic ships and railway transportation, improved loading efficiency through batch transportation and a reduced number of shipments. However, in absolute terms, CO2 emissions increased by 504 tons from FY2013 to 12,902 tons owing to the inclusion of emissions by the expanded companied in the target. Benchmarking the volume of CO2 emissions per 1,000 ton-kilometers in FY2010 as one, the indexed volume of CO2 emissions from logistics in FY2014 was 1.107.

    In FY2015, Teijin will continue to leverage collaboration among Group business divisions and establish more collective stocking points to improve loading efficiency with batch transportation, and make progress reducing domestic truck transportation by unloading the maritime shipment of imported products at ports in close proximity to customers.

    • Until FY2013, the scope for calculating CO2 emitted by logistics comprised Teijin Limited (excluding the aramid fiber business), Teijin DuPont Films Japan Limited, 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.
    • 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.

    Despite the impementaiton of these activities, total CO2 emitted was 13 kilotons in FY2014 (a 5% increase compared to FY2013)a red star

  • Reducing Chemical Substance Emissions

    Promoting Targeted Reductions From an "Environmental Impact Risk" Perspective

    The Teijin Group utilizes LIME2*to focus on managing/reducing chemical substances that have a large impact on the environment and ecosystems. LIME2 allows quantitative measurement of the environmental impact of chemical substances on human health, biodiversity and sectors such as agriculture, fisheries and forestry.

    Focusing on managing and reducing substances that have a large impact on the environment even in small amounts, targets are set based on not only the volume of chemical substances emitted, but the level of impact they have as well. In FY2014, the environmental impact assessment value (integration coefficient) for the Teijin Group as a whole decreased 6% compared to FY2013.

    Impact on Atmosphere and Impact Due to Water Usage and Wastewater

    In FY2014, the Teijin Group used a total of 81 million tons of freshwater (industrial water, groundwater and tap water). In addition, we used 46 million tons of seawater, mainly for cooling applications. Freshwater consumption increased by 2% compared to FY2013, as certain Group businesses switched some of the seawater they were using to freshwater. Total water consumption was about the same amount as FY2012. As a result of group-wide efforts to reduce waste water, the total amount of water discharged by the Teijin Group decreased by 4% year on year to 116 million tons in FY2014.

    The total amount of chemical oxygen demand (COD) load and biochemical oxygen demand (BOD) load associated with the water discharged group-wide was 538 tons (a 34% decrease from FY2013).

    Meanwhile, SOx emissions resulting from fuel use in FY2014 were 3.1 kilotons (a 21% decrease from FY2013). Of this total, overseas emissions were 0.06 thousand tons.

  • 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 resulting from business activities have on biodiversity, the Teijin Group has clarified the risks relating to loss of biodiversity due to business activities and activities to conserve biodiversity. As a result, this will facilitate Teijin Group employees having a clear awareness of the impact of business activities on biodiversity, helping to propel conservation activities forward. Future efforts will involve reviews aiming towards quantifying the effect of each initiative.

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

    In May 2015, external experts and 10 employees conducted a biological field study at the Matsuyama Factory using the Japanese Business Initiative for Biodiversity (JBIB)'s Plant & Wildlife Monitoring Sheet.

    The experts and employees conducted surveys of birds and insects on three locations within the factory and a nearby green area. Many living organisms were observed. Of particular note were the spotting of breading colonies of four species of heron, the bird songs of Japanese bush warblers, and the flight of black dragonflies (anax nigrofasciatus nigrofasciatus), which provided evidence that the Matsuyama factory's potential for sustaining biodiversity was comparatively high among the Group's factories.

    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 that had grown out to provide birds and insects with multiple layers of space.
