Reason for the Issue's Importance

To align with the government's 2050 net-zero carbon emissions target, greenhouse gas inventory and emissions have been identified as a Major Issue. Following the ISO 14064-1 greenhouse gas inventory, it was found that indirect energy emissions from purchased electricity accounted for more than 90% of the combined total emissions of Category 1 and Category 2 across the entire plant. Therefore, the Company places great importance on energy use.

Impact

  • Economic Potential Negative Impact:
  1. To align with the government's net-zero carbon emissions target, the introduction of low-carbon investments, whether through replacing energy-intensive equipment or adopting circular economy practices, will increase operating expenses and raise product unit prices.
  2. Since our company's products are exported to Europe and the United States, facing the implementation of a carbon tax system at export destinations will increase production costs.
  3. Excessive national electricity consumption and insufficient power supply lead to rising electricity prices, thus increasing production costs.
  4. In response to global concern over the consequences of the greenhouse effect and the goal of achieving net-zero emissions by 2050, the Company has replaced energy-consuming equipment and adopted environmentally friendly raw materials to reduce carbon emissions in compliance with applicable regulations. To align with the government's 2050 net-zero policy, additional improvement costs are required.
  • Potential positive impact on corporate image: Reducing carbon emissions can lower the carbon footprint of our products, thus increasing the Company's market competitiveness.
  • Potential positive environmental impact: Using energy-saving equipment and making green investments can effectively reduce electricity costs and greenhouse gas emissions, leading to environmental friendliness.
  • 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

  1. Since 2021, the Company has proactively conducted ISO 14064 greenhouse gas inventories and ensured the accuracy of the inventory data through audits by a third-party verification institution. Starting from 2021, we have arranged annual greenhouse gas inventories to confirm whether the Company's greenhouse gas inventory data shows a downward trend year by year.
  2. Starting from the end of 2023, we began monitoring the energy consumption of more energy-intensive equipment. Once monitoring is complete, we will prioritize improving or replacing the most energy-intensive equipment to achieve energysaving and carbon reduction effects.
  3. In 2025, we implemented ISO 50001 and energy monitoring equipment to monitor energy usage.
  4. New plant planning includes solar panels and storage equipment to reduce purchased electricity and carbon emissions through self-generated green power.

  3. We have developed low-VOC (volatile organic compound) inks and achieved a 90% adoption rate.

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 2025, the total greenhouse gas emissions amounted to 1,245.3575 metric tons of CO2e. Of this, direct emissions and indirect energy emissions totaled 1,003.6133 metric tons of CO2e, representing an approximate 20.548% reduction compared to the baseline year. The decrease in total carbon emissions in 2025 compared to 2024 is attributed to a significant increase in outsourced orders. This led to a reduction in average annual working hours and lower electricity consumption for air conditioning and printing production, thereby contributing to an overall decrease in emissions.

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. In 2025, the air compressor was replaced to address frequent occurrences of insufficient air pressure, which resulted in energy waste. After implementation, approximately 55,328 kWh of electricity can be saved annually.
  2. In 2025, the adsorption dryer was replaced to improve its operating efficiency. After implementation, approximately 4,732 kWh of electricity can be saved annually.
  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 100-metric-ton chilled water air conditioning system with an air-cooled air conditioning one. The old chiller units in the plant area were replaced with new chiller units. After implementation, approximately 799,344 kWh of electricity can be saved.
    (3) Adjust air compressors to frequency conversion equipment.
    (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.
