Management Policy

Reason for the Issue's Importance

After the ISO 14064-1 greenhouse gas inventory, it was found that indirect emissions from energy, specifically the purchased electricity for the entire plant, account for over 90% of the total emissions in categories one and two. Therefore, the company places great emphasis on energy usage.

Impact and Influence

  • Economic Potential Negative Impact:
    1. Excessive national electricity consumption and insufficient power supply leading to increased electricity costs, thus increasing production costs.
    2. To achieve the policy 2050 net-zero emissions target, implementing the replacement of energy-consuming equipment, and using environmentally friendly raw materials to reduce carbon emissions, which increases operating costs and expenses through green investment.
  • Environmental Potential Positive Impact: Using energyefficient equipment and green investments can effectively reduce electricity costs and greenhouse gas emissions, achieving an ecofriendly environment.
  • Actual positive human/human rights impact: All raw material suppliers and cooperating manufacturers are required to comply with government regulations prohibiting the use of banned substances in raw materials, ensuring adherence to regulations.

Policy/Strategy

At the end of 2023, the company began monitoring energy usage for high-energy-consuming equipment. Once monitoring is complete, the most energy-consuming equipment will be improved or replaced to achieve energy conservation and carbon reduction.
Additionally, the company started planning the installation of solar panels and energy storage equipment in new factories to use selfgenerated green electricity, reducing the reliance on purchased electricity and carbon emissions.

Goals and Targets

  • 短期目標：完成盤點耗能設備、執行能源監控。預計逐年汰換高耗能設備，例如：壓合機加熱器、空壓機、燈泡等設備，達到每年降低1%用電量之短期能源目標。
  • 中期目標：更換冰水主機或壓合機加熱設備、增設儲能設備及使用太陽能綠電。
  • 長期目標：開發PETG友善環境材料、由ISO 14001 環境管理系統、ISO 14064-1 溫室氣體盤查及ISO 50001 能源管理系統以尋找可持續改善之機會。

Management Evaluation Mechanism

導入ISO 50001 能源管理系統以提升能源績效，且每年皆針對ISO 14001 環境管理系統及ISO 14064-1 溫室氣體盤查進行PDCA 之有效性評量。

Performance and Adjustments

2024年底時計畫啟動陸續建置，將現場作業區內較耗能的機台設備上安裝能源管理偵測系統，藉此觀察出較耗能的設備並加以汰換已達減碳之目標。

Preventive or Remedial Measures

Continuously implement plans to replace old and energyconsuming equipment and accelerate green procurement.

Energy-Saving Achievements

Currently, the company's specific action plans for energy saving and carbon reduction are as follows. In addition to the established carbon reduction strategies, when the company starts the greenhouse gas inventory projects from Category 3 to Category 6 in the future, the focus will be on the concept of reducing the product's carbon footprint, thereby helping to reduce carbon emissions on the client side.
  1. From mid-November 2023, printing night shift personnel start earlier and install split air conditioners in other night shift work units, allowing the central air conditioning system to rest briefly and reduce energy consumption from electricity use.
  2. In 2024, the heating system of press machine No. 2 will be modified to match that of machine No. 3 to achieve energy savings and carbon reduction. It is estimated that this change will save approximately 100 kWh per day, totaling about 25,000 kWh or 90 GJ annually.
  3. From the perspectives of air conditioning systems, electric lighting, and other electricity usage, implement energy-saving measures:
    1. Replace traditional T5 fluorescent lamps with LED T5 lamps in the plant, saving 90,360.9 kWh/year (325.30 GJ), reducing electricity costs by approximately 42.5%.
    2. 60噸重之冰水式空調移除，改為氣冷式冷氣設備。
      廠區舊有冰水主機汰換成新型冰水主機，每日耗電量可節省372.667KW，相當於總共可節省耗電量372.667KW /24*8*220(工作天)(共計半年時間)，約為20.3%耗電量。相關說明如下，舊冰水主機耗電量(KW)/汰換新型冰水主機後耗電(KW)= 372.667/1,836.6667*100%=20.3%。
    3. 安裝室內冷氣於林口廠印刷區供夜班生產作業使用，可減少電力使用量161,981KWH及減碳80.019公噸CO2e。
    4. Change air conditioning in the production area to VRV type, controlling temperature settings.
    5. Replace old water-cooled air conditioners in the office with energy-efficient grade 1 split air conditioners.
    6. Fill in the fish pond in the plant area to reduce water usage.
    7. Implement online DCN approval and establish a digital engineering system.
  4. 2023年總用電度數2,424,360度，2024年度總用電度數2,153,200度，2024年較2023年總節電度數達271,160度，約為489.02千兆焦耳(GJ)，用電度數下降25.29%，即減少133.95公噸CO2e排放。
