Air pollution management

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

  • Short-term Goals : Complete inventory of energy-intensive equipment and implement energy monitoring. Plan to gradually replace high-energy-consuming equipment annually, such as lamination machine heaters, air compressors, and light bulbs, to achieve a short-term energy target of reducing electricity consumption by 1% each year.
  • Mid-term Goals : Replace chiller units or lamination machine heating equipment, install additional energy storage equipment, and utilize solar green electricity.
  • Long-term Goals : Develop PETG environmentally friendly materials and identify opportunities for continuous improvement through the ISO 14001 Environmental Management System, ISO 14064-1 Greenhouse Gas Inventory, and ISO 50001 Energy Management System.

Management Evaluation Mechanism

We have introduced the ISO 50001 energy management system to improve energy performance. Conducts PDCA effectiveness evaluations for the ISO 14001 environmental management system and ISO 14064 greenhouse gas inventory annually.

Performance and Adjustments

At the end of 2024, we progressively installed an energy management detection system on energy-intensive machinery within our operational areas. This allows us to identify the most power-consuming equipment and replace it, thereby achieving our carbon reduction goals.

Preventive or Remedial Measures

Continuously implement plans to replace old and energy-consuming equipment and accelerate green procurement.

Greenhouse Gas Emission Statistics

Our company began implementing greenhouse gas (GHG) inventory checks in 2021, alongside third-party verification to ensure the accuracy and validity of the data. This practice has continued annually, with 2022 established as TNP's GHG inventory baseline year. For this reporting year, the total greenhouse gas emissions amounted to 1,403.6067 metric tons of CO2e. Of this, direct emissions and indirect energy emissions totaled 1,169.52 metric tons of CO2e, representing an approximate 8% reduction compared to the baseline year. The decrease in total carbon emissions in 2024 compared to 2023 is attributed to a significant increase in outsourced orders.

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.
