Management Policy

Reason for the Issue's Importance

配合政府2050年淨零碳排目標，故將溫室氣體盤查及排放列入重大主題。經ISO 14064-1 溫室氣體盤查後發現能源間接排放- 全廠外購電力占類別一&類別二的總和排放量至少九成以上，因此本公司非常重視能源的使用。

Impact and Influence

  • Economic Potential Negative Impact:
  1. To meet the government's net-zero carbon target, introducing low-carbon investments, whether by replacing energyintensive equipment or implementing a circular economy, will increase operating expenses and raise product 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 leading to increased electricity costs, thus increasing production costs.
  4. 全球重視溫室效應之後果，且訂定2050年淨零排放影響，為配合法規實施汰換耗能設備、使用環保型原物料以降低碳排放量，以配合政府2050年淨零政策，需增加改善費用。
  • 企業形象潛在正面衝擊：降低碳排可降低產品碳足跡，增加本公司產品於市場的競爭力。
  • 環境潛在正面衝擊：使用節能設備、綠色投資，可有效減少電費費用及溫室氣體排放量，並達到友善環境。
  • 人/人權實際正面衝擊：為達成政府淨零政策，要求各原物料商及配合廠商均需依政府規定禁止使用禁用物質原物料、以遵循法規。

Policy/Strategy

  1. 2021年進行ISO 14064溫室氣體盤查並通過第三方查證單位稽核確認盤查數據之正確性，自2021年起安排每一年做溫室氣體盤查，確認本公司溫室氣體盤查數據是否有逐年下降之趨勢。
  2. 2023年底開始針對較耗能之設備監控其能源的使用，待監控完畢後將從最耗能之設備先進行改善或汰換，以達到節能減碳之效果。
  3. 2025年已導入ISO 50001及能源監控設備，以進行監控能源使用。
  4. 於新建廠房規劃建置太陽能板及儲能設備，藉由綠電自發自用，降低外購電力之使用及碳排。

  2. 2025年以能源管理偵測系統監控現場作業區內較耗能的機台設備上，藉此觀察出較耗能的設備並加以汰換已達減碳之目標。
  3. 開發低揮發性油墨，已達成90%導入率。

Preventive or Remedial Measures

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

Greenhouse Gas Emission Statistics

本公司於2021年開始執行溫室氣體盤查，同步進行第三方查證確保數據之準確性及有效性，並於接續之每年皆有做溫室氣體盤查，並將2022年定義為台灣銘板之溫盤基準年。於本報導2025年度之溫室氣體排放總量達1,245.3575公噸CO2e，其中直接排放與間接能源排放達1,003.6133公噸CO2e，相較基準年減少約20.548%。同時，2025年的總碳排放量相較 2024年數據下降是因為訂單大量採外製，整年度平均工時減少、降低冷氣及印刷生產用電量，以降低用電量的方式促使整體排放量下降。
