インドネシア国営製油所PT KPIの2026〜2030年脱炭素ロードマップを、TOWSマトリクスとDynamic Capability理論で評価した単一企業ケース研究。2020〜2024年にScope1+2を約16.3%削減した一方、2023年のエネルギー強度指数は107.8と基準値100を上回り、削減が構造的な効率改善によるものか確認できなかった。優先戦略は製油所間のエネルギー性能調和、ユーティリティ・プロセス転換、炭素リスク対策としての効率統合で、デジタル管理システム強化が続く。著者らはこれを深掘り脱炭素ではなく移行準備段階と位置づけ、絶対排出量開示と並ぶ正規化性能報告の必要性を指摘する。

English

A single-case study of Indonesian state-owned refiner PT KPI evaluates its 2026–2030 decarbonization roadmap using a TOWS matrix and Dynamic Capability Theory. Scope 1+2 emissions fell ~16.3% (2020–2024), yet the 2023 Energy Intensity Index of 107.8 exceeded the internal benchmark of 100, so structural efficiency gains could not be confirmed. Top priorities are cross-refinery energy-performance harmonization, utility/process transformation, and efficiency as carbon-risk mitigation, with digital energy management fourth. The authors frame the roadmap as transition-enabling rather than deep decarbonization and call for normalized performance reporting alongside absolute emissions disclosure.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本のSSBJ・有報開示では絶対排出量と原単位（エネルギー強度）の双方開示が議論されており、両者の乖離を診断する本手法は日本企業のScope1/2開示の質的向上に示唆を与える。国営・多拠点・エネルギー多消費企業という条件は日本の製造業・電力にも共通する。

In the global GX context

Speaks directly to the ISSB/CSRD debate on whether absolute emissions disclosure alone suffices, arguing for normalized intensity metrics as a complement. Offers a transferable diagnostic for state-owned, multi-site, energy-intensive firms in emerging markets navigating transition finance and net-zero roadmaps.

👥 読者別の含意

🔬研究者:絶対排出量と原単位指標の乖離を測る診断枠組み（TOWS×Dynamic Capability）の適用例として参照できる。

🏢実務担当者:Scope1/2削減を構造的効率改善と結びつけて説明する際、正規化指標の併記が投資家・規制対応の説得力を高めることを示す。

🏛政策担当者:排出量開示に原単位・正規化性能指標を組み合わせる規制設計の根拠として活用できる。

📄 Abstract（原文）

Background: This study evaluates the 2026–2030 energy efficiency and decarbonization roadmap of PT Kilang Pertamina Internasional (PT KPI) to examine the gap between absolute greenhouse gas emission reductions and actual structural energy efficiency improvements. Objective: This study examined this diagnostic tension at PT Kilang Pertamina Internasional (PT KPI) by evaluating its energy-efficiency and decarbonization roadmap for 2026–2030. Methods: The study used a single corporate case design combining primary company data (2020–2024 emissions records and 2023 Energy Intensity Index data), document review, and structured judgment from a five-member expert panel, analyzed through a TOWS matrix informed by Dynamic Capability Theory. Results: PT KPI reduced combined Scope 1 and Scope 2 emissions by approximately 16.3 percent between 2020 and 2024, while its 2023 Energy Intensity Index of 107.8 remained above the company's internal reference value of 100, indicating that the decline could not be confirmed as evidence of structurally embedded efficiency improvement given the limited normalized performance data available. Energy-performance harmonization across refinery units, utility and process-system transformation, and the integration of energy efficiency as a carbon-risk mitigation instrument emerged as the three highest-priority strategies (SPI 5.00, 4.76, and 4.36, respectively), with digital energy-management-system strengthening ranked fourth (SPI 4.24). Conclusion: These priorities were found to establish necessary governance and measurement foundations but to be insufficient, on their own, to achieve net-zero targets by 2060, positioning the 2026–2030 roadmap as a transition-enabling phase rather than a deep-decarbonization pathway. The findings offer a transferable diagnostic approach for other multi-site, state-owned, energy-intensive enterprises facing comparable data and governance constraints, underscoring the need for normalized performance reporting alongside absolute emissions disclosure.
