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

The Company's current specific action plans and achievements in energy saving and carbon reduction are detailed below. Beyond our established carbon reduction strategies, once we begin to inventory Categories 3 to 6 greenhouse gas emissions, we will help reduce our clients' carbon emissions by focusing on minimizing product carbon footprints.
  1. Starting in mid-November 2023, we implemented a measure for night-shift printing personnel to start work earlier, and installed split air conditioning units in other night-shift work areas. These measures allow the central air conditioning system to have brief periods of rest, thereby reducing electricity consumption and energy emissions.
  2. In 2024, we modified the heating system of the #2 lamination machine to match the mode of the #3 machine, to achieve energy saving and carbon reduction. This is estimated to save approximately 100 kWh per day, totaling 25,000 kWh, which is 90 GJ.
  3. From the perspectives of air conditioning systems, electric lighting, and other electricity usage, implement energy-saving measures :
    1. Our plant has replaced traditional T5 fluorescent lights with LED T5 ones. This upgrade is expected to save 90,360.9 kWh of electricity annually, which translates to 325.30 GJ, and reduces electricity costs by approximately 42.5%.
    2. Removed and replaced the 60-metric-ton chilled water air conditioning system with an air-cooled air conditioning one.
      Our plant has replaced its old chillers with new, more efficient models. This upgrade is expected to save 372.667 kW in daily power consumption. This translates to a total electricity saving of approximately 20.3% over half a year (372.667KW / 24*8*220 working days). The relevant details are as follows: Power consumption of old chiller (kW) / Power consumption of new chiller (kW) × 100% = (372.667 / 1,836.6667) × 100% = 20.3%.
    3. By installing indoor air conditioners in the Linkou Plant’s printing area for night-shift production, we anticipate reducing electricity consumption by 161,981 kWh and cutting carbon emissions by 80.019 metric tons of 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. In 2023, total electricity consumption was 2,424,360 kWh, which decreased to 2,153,200 kWh in 2024. This represents a total electricity saving of 271,160 kWh in 2024 compared to 2023, equivalent to approximately 489.02GJ. This 25.29% reduction in electricity consumption led to a decrease of 133.95 metric tons of CO2e emissions.
