Renewable energy certificate mechanism and markets in Taiwan: The evolution and characteristics

With the world striving to achieve net-zero emissions by 2050, carbon-free energy systems must accelerate. This study examines how Taiwan’s renewable energy certificate (T-REC) assists Taiwan-based global enterprises in meeting supply chain requirements and establishing a renewable energy certification and initial market system with reliability and validity. The analysis examines several critical dimensions, including government-led initiatives, the voluntary nature of the program, the design of bundled certificates, and their integration with the national greenhouse gas registry. From an institutional perspective, it can be affirmed that the institutional design of the T-REC aligns with the fundamental purpose of energy attribute certificates in promoting the development and utilization of electricity derived from renewable sources. The reliability of the T-REC can be strengthened through government-led governance. Furthermore, the T-REC tracking system is integrated with the national greenhouse gas registry platform to prevent the double-counting of environmental benefits. From a market perspective, the design of the T-REC shapes the quality and operational regulations of the initial renewable electricity trading market.

以無碳電力憑證推動電力部門淨零轉型

臺灣具有天然的二氧化碳地質封存資源優勢。以海域而論，依歷年學者之研究，至少包括桃園-新竹海域盆地、台西盆地、雲林嘉義外濱3處海域。若依照IEA於2021年提出全球淨零排放路徑里程碑之建議，至2040年應淘汰所有未減排的燃煤與燃油電廠。因此，除了大規模增加再生能源使用外，未來臺灣若要建構去碳能源系統，勢必需導入碳捕捉與封存技術，以達到淨零轉型。

有鑑於再生能源憑證實際運作機制，當消費者之電力來源為火力電廠時，火力電廠導入碳捕捉與封存技術後，若可有效去除化石能源燃燒所造成溫室氣體排放量，則電廠所產生的電力可視為無碳電力（Carbon-free Power）。未來若歐盟碳邊境調整機制（Carbon Border Adjustment Mechanism, CBAM） 規範對象擴及至複雜商品或間接排放，建立無碳電力憑證機制可將導入碳捕捉與封存技術電廠價值鏈外溫室氣體減量轉換成價值鏈內溫室氣體減量，促進淨零正向循環經濟。
