印尼近 60 億美元石化擴產計畫，氣候目標面臨碳鎖定考驗

印尼推進近 60 億美元 PT Taikun 石化投資，規劃每年生產 720 萬噸產品。連同芝勒貢大型乙烯產能，產業擴張正考驗印尼氣候與工業減碳目標。

Indonesia is advancing a nearly USD 6 billion PT Taikun petrochemical investment with planned output of 7.2 million tonnes a year. Together with major ethylene capacity in Cilegon, the expansion tests national climate and industrial decarbonisation goals.

政府將石化視為進口替代、就業與產業升級的重要基礎。PT Taikun 專案被估計每年可貢獻約 90 億美元國內生產毛額，Lotte 新廠則具每年 100 萬噸乙烯能力。

The government treats petrochemicals as a foundation for import substitution, employment and industrial upgrading. PT Taikun is projected to contribute about USD 9 billion annually to GDP, while Lotte's new plant can produce one million tonnes of ethylene a year.

石化設施壽命長，新增產能可能鎖定燃料與製程排放。國家戰略專案享有部分程序便利，也使投資速度與減碳規範建置出現時間落差。

Petrochemical assets are long lived and can lock in fuel and process emissions. Procedural advantages for national strategic projects can also create a timing gap between investment and decarbonisation rules.

印尼正準備工業減碳規則，預計 2026 年底前提出。企業可先推進能效、電力替代、低碳原料、製程改造及碳管理，但每項工具的技術與成本條件不同。

Indonesia is preparing industrial decarbonisation regulation expected by late 2026. Companies can advance efficiency, cleaner power, lower-carbon feedstocks, process changes and carbon management, although technical and cost conditions differ.

2022 年印尼工業直接製程排放約 1,030 萬噸二氧化碳當量，其中石化約占四分之一。報導指出僅靠能效到 2050 年可能最多降低約 15%，顯示深度減排仍需更大結構變化。

Indonesia's direct industrial process emissions were about 10.3 million tonnes of carbon dioxide equivalent in 2022, with petrochemicals accounting for roughly one quarter. Reporting suggests efficiency alone may cut no more than about 15 percent by 2050.

短期投資可改善貿易與供應安全，長期卻可能面臨碳成本、低碳產品標準與擱置資產風險。出口市場規則會把工廠排放轉化為競爭條件。

Investment can improve trade and supply security in the short term, while creating future carbon-cost, low-carbon product standard and stranded-asset risks. Export rules can turn plant emissions into a competitiveness condition.

SNN 編輯分析：產業政策需要把投資核准、設備壽命、能源投入、產品產量與排放路徑放在同一決策紀錄，才能辨識成長是否形成不可逆碳鎖定。

SNN editorial analysis: Industrial policy should connect investment approval, equipment life, energy inputs, production and emissions pathways in one decision record to identify irreversible carbon lock-in.

後續應追蹤減碳規則、PT Taikun 最終投資與建設、Lotte 實際產能利用、能源來源、產品碳強度及主要出口市場要求。

Next checks should cover the decarbonisation regulation, final investment and construction at PT Taikun, Lotte utilisation, energy sources, product carbon intensity and requirements in major export markets.
