インドネシアの炭素排出量取引（IDXCarbon）の2025年時点の発展とメカニズムを分析した研究。発電部門のキャップ・アンド・トレードとSPE-GRK（オフセット）の二本柱で運用され、削減事業者への経済的インセンティブ、緩和資金、排出データ透明性の向上をもたらす。一方、低い市場流動性、社会的炭素費用を反映しない価格、検証能力の制約、部門カバレッジの不完全さが課題と指摘する。
English
This study analyzes the development and mechanisms of Indonesia's carbon emissions trading (IDXCarbon) in 2025. It operates via cap-and-trade in power generation and SPE-GRK offset credits, offering economic incentives, mitigation finance, and better emissions transparency. Key obstacles include low liquidity, prices below the social cost of carbon, limited verification capacity, and incomplete sectoral coverage.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではSSBJ基準・GX-ETS・カーボンクレジット市場が整備途上にあり、新興国ETSの設計・課題（流動性、価格水準、検証体制）は日本の制度設計や企業の海外クレジット調達戦略に示唆を与える。
In the global GX context
As ISSB/CSRD disclosure expands and Article 6 carbon markets mature, Indonesia's IDXCarbon offers a Global South case of a nascent ETS with cap-and-trade plus offsets. It highlights common challenges—liquidity, price discovery, MRV capacity—relevant to other emerging carbon markets and to cross-border credit trade.
👥 読者別の含意
🔬研究者:新興国ETSの制度設計と運用実態を、流動性・価格・検証能力の観点から整理した事例研究として参照できる。
🏢実務担当者:インドネシアで事業展開する企業は、SPE-GRKクレジット調達や発電部門のコンプライアンス義務の実務的制約を把握するのに有用。
🏛政策担当者:炭素市場の有効性には厳格なキャップ、部門拡大、検証体制強化が不可欠という政策的含意を提供する。
📄 Abstract（原文）
Climate change requires every country to reduce greenhouse gas (GHG) emissions through policy instruments that are both effective and economically efficient. Indonesia has positioned carbon emissions trading as one of the main instruments for achieving its Nationally Determined Contribution (NDC) target through the implementation of carbon economic value and the operation of the Indonesia Carbon Exchange (IDXCarbon). This study aims to analyse the development of carbon emissions trading in Indonesia in 2025, explain its trading mechanisms, and identify the benefits and obstacles of its implementation as an emission control instrument. The study applies a descriptive qualitative approach using secondary data obtained from government regulations, publications of the Ministry of Environment and Forestry, data from the Indonesia Carbon Exchange, and related journal articles. The results show that carbon trading in Indonesia operates through two main mechanisms, namely emission allowance trading (cap-and-trade) in the power generation subsector and carbon credit (offset) trading in the form of GHG Emission Reduction Certificates (SPE-GRK), which are equivalent to the concept of Certified Emission Reduction (CER). These instruments provide economic incentives for emission-reducing businesses, financing for mitigation actions, and improved transparency of emission data. Nevertheless, the implementation still faces obstacles such as low market liquidity, carbon prices that do not yet reflect the social cost of carbon, limited verification capacity, and incomplete sectoral coverage. The study concludes that carbon emissions trading can become an effective emission control instrument if supported by stronger regulation, broader sectoral coverage, and stricter emission caps.
