針對台灣碳交易結合區塊鏈可行性之研究

現今全球能源市場正處於一個轉型階段，傳統的中心化能源交易系統面臨著成本高昂的中心化數據庫建設和維護、數據被篡改後可能會導致嚴重後果，以及難以保障用戶隱私等三大挑戰。在這樣的背景下，越來越多的國家將目光轉向區塊鏈技術，以應對這些問題，特別是在碳權交易領域。然而，目前台灣碳交易仍然使用的是傳統的交易架構。因此，針對如何在台灣現有交易架構下有效的整合區塊鏈技術，已成為企業極需重視的議題。本研究通過彙整區塊鏈相關文獻，梳理了在區塊鏈應用中的實際使用情況，透過對這些系統的組成進行了深入分析，並輔以專家訪談，了解專家對於碳交易結合區塊鏈的可行性之看法。根據初次訪談結果及文獻綜述，本研究設計了一個區塊鏈碳交易雛型系統。在系統建置完成後，進行專家使用心得訪談，彙整出雛型系統設計原則與改善建議，為下一代系統設計的可行參考依據。此外，本研究還會總出區塊鏈技術與碳交易結合的可行性分析，並為後續台灣政府對碳交易系統的設計流程提供建議。

The contemporary global energy marketplace is in the midst of a pivotal transformation. Traditional, centralized modalities of energy trade are contending with formidable adversities, including the exorbitant outlays requisite for the establishment and sustenance of centralized databanks, the grave ramifications of data infringement, and the intricacies entailed in the protection of consumer confidentiality. Within this milieu, there is a burgeoning inclination among nations to pivot towards blockchain technology as a panacea for these impediments, with a pronounced focus on the domain of carbon emissions commerce. Nonetheless, the extant carbon trading infrastructure in Taiwan is predicated on conventional transactional frameworks, thereby rendering the seamless assimilation of blockchain into Taiwan's extant trading edifice a matter of acute commercial imperative. This study consolidates blockchain-related literature to analyze the actual usage of blockchain applications globally. Through an in-depth analysis of these systems' components, coupled with expert interviews, the feasibility of integrating blockchain technology with carbon trading was examined. Based on the initial interview results and literature review, a prototype blockchain-based carbon trading system was designed. After the system was built, a second round of expert interviews was conducted to gather feedback on the system's usability and to compile design principles and improvement suggestions for the prototype. This provides a feasible reference for the next generation of system design. Additionally, this study offers a feasibility analysis of integrating blockchain technology with carbon trading and provides recommendations for the design process of carbon trading systems to inform future government policy in Taiwan.
