Sustainable Supply Chain

Winbond anchored its sustainable supply chain program in "Practicing Responsible Procurement," and a "People-oriented", integrating ecosystem thinking into governance and day-to-day supply chain operations. Through the dual transformation pillars of digitalization and decarbonization, Winbond strengthened controls, data collection, and collaboration mechanisms to support measurable progress.
In a volatile operating environment, maintaining business continuity requires innovation and agile response. Winbond worked with suppliers through audits, training, and digital data systems to strengthen operational resilience and manage ESG risks across the supply base.
Winbond strengthened supplier engagement and expanded value-chain collaboration. In 2025, Winbond received an A rating in the CDP Supplier Engagement Assessment (SEA), achieving Leadership level recognition.
Through value-chain climate collaboration, Winbond supported partners’ low-carbon transition and co-developed a climate-resilient sustainable supply chain ecosystem.

Low-carbon Supply Chain Strategy and Management

Addressing significant concerns about extreme climate events and reducing carbon emissions has become a primary focus for international brand manufacturers. Achieving net-zero emissions by 2050 has garnered consensus among numerous countries and enterprises worldwide. Winbond advocates leading by example and believes that effective propagation of carbon reduction efforts starts internally.

Internally, Winbond has established sustainable procurement practices (including local, circular, and green procurement), implemented an internal green logistics management system, and supported outsourced partners in developing low-carbon technologies. Externally, Winbond encourages and promotes carbon reduction initiatives among suppliers, regularly collects data to monitor progress towards carbon reduction goals, organizes various supplier engagement activities to build consensus on carbon reduction, and collaborates with government subsidy projects to reduce carbon management costs for suppliers and lower entry barriers. Together with suppliers, Winbond aims to become a responsible corporate citizen committed to sustainable practices.

Low Carbon Supply Chain Strategy - Comprehensive Carbon Reduction Management

以身作則-供應鏈源頭減碳趨力

為有效往2050 淨零目標邁進，2025 年除了持續辦理與節能減碳相關的供應商ESG 議合活動外，華邦臺灣擴大供應鏈減碳的範疇，以身作則，從範疇三減量做起，包括上游運輸、後段封裝量測服務、廢棄物處理等，年度碳排減量達11,459 tCO₂e；並持續鼓勵供應商設定科學基礎減量目標 (SBTi)。在供應鏈合作部分，華邦臺灣2023年與13家供應商聯合向經濟部產業發展署申請「以大帶小製造業低碳化及智慧化升級轉型補助」，該專案2年內與供應商合作完成逾30項減碳工作，減碳1萬9,995 tCO₂e，大幅超出目標240%。鑑此，以「以身作則- 內部範疇三減碳」及「擴散與影響- 供應鏈低碳治理」兩大面向為主軸，展現低碳供應鏈治理績效。

2025 年內部範疇三減碳

類別	重點工作項與減碳績效
原物料減碳	2025 年輔導關鍵供應商完成產品碳盤查，上游價值鏈（範疇三－類別 1）年度減碳達 4,625.8 tCO₂e。
上游運輸	完成 9 項關鍵物料多方溯源，其中 6 項轉為在地採購，降低碳排放量 725.0 tCO₂e。導入共享物流機制，洽談 2 家供應商加入趟次共享運輸模式，年度減碳量 0.3 tCO₂e。推動包裝優化 2.0 與進出口低碳運輸作業無紙化，樣品出貨採安全且精簡之包裝方式，年度總計降低 251.6 tCO₂e。
後段封裝量測服務	定期實施產品碳足跡盤查，2026 年將進行第三次盤查，持續追蹤主要 7 家封測廠產品碳排放變化。持續推動包裝材料減碳專案，包括靜電箱取代紙盒、Reel 捲盤材料減量、Carrier Tape 與 Tube material 回收再使用、取消重複標示標籤，共計降低 285.9 tCO₂e。封裝測試導入節能型測試生產機台，共計降低 3,702.0 tCO₂e。
廢棄物處理	IPA 廢液調降焚化處理比率，台中廠由 30% 降至 15%，高雄廠由 20% 降至 10%，2025 年度總計降低 391.2 tCO₂e。新增廢保麗龍、中空板及純水濾心由焚化改為再利用，2025 年度總計降低 3.9 tCO₂e。

永續採購力

華邦致力於攜手供應商成為永續「+1」夥伴，積極以採購工作發揮永續影響力，將經濟效益轉化為與既有及潛在供應商共榮的長期動力。2025年華邦全面落實三大永續採購策略：以「在地採購」降低國際運輸之溫室氣體排放；以「循環採購」促進物質循環再利用；以「綠色採購」驅動業者開發環保產品與服務。

在地採購

循環採購

綠色採購

說明

為確保華邦整體營運韌性，我們將晶圓製造所需之關鍵原物料(化學品、氣體、靶材、晶圓)列為在地採購重點。總觀2025 年的外部挑戰，新型國際氣候協定、碳費開徵、關稅疊加、通膨調控及供應鏈區域化及短鏈等現象，持續影響華邦之供應鏈韌性與營運穩定。鑒此，我們聚焦兩項工作重點：積極提高工廠端綠色與低碳製程，並優化關鍵原物料在地採購配比，以強化韌性並降營運風險。總結而言，2025 年華邦(臺灣)在地採購金額比例為 37.3%；新唐(臺灣)為30.3%；新唐(日本)為43.7%，佔比皆維持30%以上。展望未來，華邦將持續針對關鍵原物料推動多軌溯源以強化韌性，並策略性擴大在地採購至生產設備、關鍵備品與零組件；同時持續評估各類供應資源的在地化可行性，以建構更具彈性且可靠的供應鏈體系。

近4 年華邦集團原物料在地採購表

說明

華邦積極實踐循環採購，聚焦中科與高雄廠營運流程，鑑別具循環效益之產品與服務，透過採購策略與供應商緊密協作，最大化資源利用效率。2025 年，華邦在廢靶材、廢晶圓及各類五金等廢棄資源的回收再製與價值化，總計創造逾 NT$1,242 萬元之循環收益，其中華邦(臺灣)為NT$1,000 萬元，新唐(臺灣)NT$242 萬元。展望未來，我們將持續優先採購具備可維修、再利用及高回收潛力的產品，落實循環型採購，加速達成永續發展目標。

2025年績效

說明

華邦(臺灣)致力於深植「綠生活」親環境理念，2025 年以採購帶動供應鏈與員工生活轉型。製造端優先導入高效能、低污染、可循環再利用之綠色設備與建材，於環境部「民間企業及團體綠色採購申報平臺」合法申報金額突破 NT$4.3 億；同仁端每季推廣綠色生活理念，截至 2025 年底，已累計 2,735 人次響應宣導。未來，將持續擴大綠色採購範疇並開發多元綠色產品與服務，並以集團型態延伸至行政與製造體系，持續注入永續動能。

2025年績效

行政院環境部民間企業及團體綠色採購申報平臺之綠色採購金額，超過NT$4 億3 千9 百餘萬元
獲頒高雄市及臺中市環保局淨零綠生活績優單位

Identifying Development Opportunities Together	5. Carbon Abatement together	Led by Winbond, and with the establishment of an ESG sustainable supply chain team, a consortium comprising 13 suppliers including raw materials, packaging and testing, machinery and equipment, and factory engineering, successfully applied for a full NT$30 million subsidy from the Industrial Development Bureau of the Ministry of Economic Affairs. In 2025, Winbond’s low-carbon transformation collaboration project within the sustainable supply chain was successfully concluded, completing over 30 carbon reduction initiatives and achieving total reductions of 19,995 tCO₂e—exceeding the target by 240%. The project was selected as an annual low-carbon achievement demonstration case by the Industrial Development Administration, Ministry of Economic Affairs. Winbond held 1 briefing session on the Sustainable Supply Chain Transformation Diagnostic Subsidy Program, with a special invitation extended to suppliers with smaller procurement volumes and limited transformation resources. A total of 220 participants attended.
