近年全球氣候變遷風險減緩與調適、及永續揭露準則快速演進，促使金融機構由最基本的「倡議與揭露」，逐步走向永續融入「治理、風險管理與業務策略」之整合落地。金融體系作為資金配置樞紐，除需管理自身營運之環境與社會責任外，更須透過授信、投資、承保、承銷及資產管理等機制，引導實體經濟與產業價值鏈邁向低碳永續轉型，同時降低自身氣候相關財務風險。
本研究以台灣金控型金融機構之代表個案——富邦金控，作為研究對象，探討其推動永續金融之治理架構、業務連結方式、氣候與永續風險管理機制，以及永續資訊揭露作法，分析其推動成效與所面臨之挑戰。
本研究採取個案研究法，以公開可得之次級資料為主，蒐集富邦金控及主要子公司之永續報告書、氣候相關財務揭露（TCFD）報告、年報、公司治理相關資訊，並輔以國內監理政策文件與國際框架（如ISSB IFRS S1/S2、NGFS情境）進行對照，透過內容分析進行跨文件之交叉驗證。研究結果顯示，富邦金控之永續金融落地主要依賴四項制度化機制：
（一）董事會層級之永續治理與跨子公司協作架構，並以永續指標目標設定與追蹤機制、績效連結機制強化當責；
（二）以永續金融政策、敏感性產業准入／撤資與退出時程等政策承諾，將永續要求內嵌至授信、投資與承保等業務核心流程；
（三）導入國際情境分析、投融資組合碳盤查等工具，搭配內部風險管理流程，以提升氣候風險辨識與管理能力；
（四）配合國內外揭露規範，以框架化、財務化揭露及第三方確信，加上資料治理及內稽內控流程制度化，提升資訊可比性與可信度。
惟在金融機構主要碳排之範疇三，即財務碳排，受限於主管機關規範時程，各產業之碳盤查普及程度與資料品質參差、亦缺乏資料收集之平台、致使金融業具體推動轉型金融之可驗證性以避免漂綠等面向，仍存在需持續精進之挑戰。
綜合而言，本研究建議金融機構自身應強化資料治理與內控留存、提升情境分析與組合指標之可用性，並以更具顆粒度之轉型計畫與成效追蹤機制支撐永續金融之長期落實，俾供同業實務推動與監理制度設計參考。

In recent years, accelerating climate change risks, the growing need for adaptation and mitigation, and the rapid evolution of sustainability disclosure standards have pushed financial institutions beyond basic advocacy and disclosure toward the systematic integration of sustainability into governance, risk management, and business strategy. As a key intermediary in capital allocation, the financial sector is responsible not only for managing the environmental and social impacts of its own operations, but also for guiding the real economy and industrial value chains toward low-carbon and sustainable transition through lending, investment, underwriting, securities underwriting, and asset management, while reducing its own climate-related financial risks. Against this backdrop, this study takes Fubon Financial Holdings, a representative financial holding company in Taiwan, as its case and examines its governance structure for sustainable finance, the integration of sustainability into core business operations, its climate and sustainability risk management mechanisms, and its approaches to sustainability disclosure and external stakeholder engagement.
This study adopts a case study approach and relies primarily on publicly available secondary data, including sustainability reports, Task Force on Climate-related Financial Disclosures (TCFD) reports, annual reports, and corporate governance disclosures issued by Fubon Financial Holdings and its major subsidiaries. These materials are supplemented by domestic regulatory policy documents and international frameworks, such as ISSB IFRS S1/S2 and NGFS climate scenarios, and are analyzed through content analysis and cross-document triangulation. The findings show that Fubon’s implementation of sustainable finance is primarily supported by four institutionalized mechanisms: (1) a board-level sustainability governance structure and cross-subsidiary coordination framework, reinforced through performance-linked accountability; (2) the embedding of sustainability requirements into core business processes such as lending, investment, and underwriting through sustainable finance policies, sensitive-sector entry and divestment criteria, and phase-out timelines; (3) the use of tools such as scenario analysis and financed-emissions accounting to strengthen climate risk identification and management; and (4) structured, finance-oriented disclosures and third-party assurance that enhance the comparability and credibility of sustainability information. Nevertheless, significant challenges remain, particularly in Scope 3 financed emissions, where uneven carbon-accounting maturity across industries, inconsistent data quality, and the absence of sufficiently robust data infrastructure continue to constrain the verifiability of transition finance and increase the risk of greenwashing. Overall, this study suggests that financial institutions should strengthen data governance and internal controls, improve the usability of scenario analysis and portfolio-level indicators, and support the long-term implementation of sustainable finance through more granular transition plans and performance-tracking mechanisms. The findings may serve as a practical reference for financial institutions and for the design of future regulatory frameworks.
