Management of GHG
  • GHG Emissions Audit By The Third Party
  • Renewable Energy Management

In order to fully control GHG emission, all production sites under FENC conduct an inventory of GHG emissions with calculation in accordance with ISO 14064-1 (greenhouse gas emissions) or local regulatory standards, and must complete third party auditing once every 3 years. Currently, all production sites have completed GHG emission audit by the third party. We believe that by establishing inventory, FENC can prioritize implementation projects to fulfill goals in carbon reduction, and ultimately mitigate the effects of climate change.

  1. Scope 1: direct emission includes CO2、CH4、N2O、PFCs、HFCs、SF6 and NF3;scope 2 indirect emission includes CO2、CHand N2O; total emission does not include CO2 emission from biofuel.
  2. OPSC and FEIS conform to SH/MRV-004-2012, which only CO2 emission is calculated.
  3. Production sites which have completed ISO 14064-1 standards for GHG inventories in 2016 included: OPTC, Hsinpu Chemical Fiber Plant, Kuanyin Chemical Fiber Plant, OPSC and FEIS.
  4. Production sites which have completed ISO 14064-1 standards for GHG inventories in 2017 included: OPTC, Hsinpu Chemical Fiber Plant, Kuanyin Chemical Fiber Plant, Kuanyin Dyeing and Finishing Plant, OPSC and FEIS, FEIW, OTIZ, FEDZ, FEAZ and FEAV.
  5. Production sites which have completed or were in progress of ISO 14064-1 standards for GHG inventories in 2018 included: OPTC, Hsinpu Chemical Fiber Plant, Kuanyin Chemical Fiber Plant, FEFC, Hukou Mill, OPSC, FEIS and WHFE.
  6. The total emission in 2018 for FENC’s 5 production sites in Taiwan is 775 kt-CO2e

►GHG Emission per Unit of Production

Unit:t-CO2e/Metric ton of product


Note:The textile business does not include FEAZ and FEAV

In 2018, the total GHG emission decreased. Such phenomenon is mainly attributed to the closing of FEIZ and the new energy saving production process implemented at OPTC. Analysis of the GHG emission per unit of production indicates an increase from the Polyester Business, which is mainly caused by adjustment in product mix at FEIS and Hsinpu Chemical Fiber Plant.

To fully implement GHG management, FENC includes staff business trips and waste treatment into the calculation of carbon inventory. The scope of staff business trip covers the mileage of air travels from and to production sites in Taiwan and China. Calculation of carbon emission between the departure and arrival points is based on the air travel carbon calculator established by International Civil Aviation Organization (ICAO). The 2018 carbon emission produced during staff business trips by air travel is 1,049 tCO2e.

 GHG Inventory Scope 3 – Expanded Scope of Waste Treatment Statistics

In 2018, FENC expanded the calculation of carbon emission of waste disposal to cover production sites in China and Vietnam in addition to Taiwan, which comes to a total of 16 sites. The calculation of carbon footprint per ton per kilometer for waste disposal at production sites in Taiwan is based on the carbon footprint emission factors released by the Environmental Protection Administration. Calculation for production sites in China and Vietnam is based on the carbon footprint coefficient issued by State Administration for Industry and Commerce’s website on carbon trading. In 2018, the annual CO2 emission for waste disposal is 2,278 tCO2e. The highest is from the Polyester Business, which is 1,118 tCO2e. The CO2 emission for Petrochemical and Textile Businesses are 813 tCO2e and 347 tCO2e, respectively.




FENC supports the use of renewable energy as well as reduction of GHG and impacts of production on the environment with actions. In 2016, phase I of solar power station began operating at OTIZ, FEDZ and FEIS. In 2018, FEIW constructed the solar power station and phase II began operation at FEIS. As of the end of 2018, a total of 18,275,000 kWh of solar had been generated at various production sites. Solar panels are typically installed on rooftops, making inspection a dangerous task. However, data provided by suppliers is unable to provide panel-specific condition. Hence the IT department of FENC developed AISolar, an information management platform which detects malfunctions and conducts real-time analysis to reduce the need for on-site patrol and inspection, which minimizes occupational hazards and enhances performance of the facilities. OPTC and OPSC plan to construct solar powerstations in 2019.

In Taiwan, FENC had been voluntarily purchasing green energy from Taipower since 2015. When Taiwan Renewable Energy Certification (T-REC) was initiated in Taiwan, the Company purchased T-REC from the Southern Region Campus of Industrial Technology Research Institute. The total renewable energy purchased has reached 900,000 kWh. In 2019, FENC will continue purchasing green energy certification. OPTC will also apply for the purchase of T-REC once the solar power station is completed in 2019, which is a show of support for the renewable energy policy in Taiwan.
