ウクライナ国家統計局の1990〜2025年のミクロ集計データを初めて構造分析し、2020/21年の次元断絶を調和させた36年系列を構築。排出は4段階で減少し、戦時下の89.3%減は脱炭素ではなく設備破壊・占領によるもので、鉄鋼−73.8%、コークス−89.6%が顕著。炭鉱メタンが固定CH4の大半を占め、CBAMデフォルト値や国内ETS設計、MRV整備への含意を導出。
English
First structural analysis of Ukraine's official 1990–2025 microaggregated emissions dataset, harmonizing the 2020/21 dimensional break into consistent 36-year series. The 89.3% fall in stationary emissions reflects wartime destruction and occupation, not decarbonization (metallurgy −73.8%, coke −89.6%). Coal-mine methane dominates stationary CH4, with implications for CBAM default values, MRV infrastructure, and Ukraine's phased ETS design.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本企業にとって直接の対象国ではないが、CBAMデフォルト値の実証的検証と、戦争・占領下でのMRV欠損という極端なケースは、SSBJ・有報でのScope3サプライチェーン開示や、地政学リスク下での排出データ信頼性確保の議論に示唆を与える。
In the global GX context
Directly informs CBAM implementation and EU ETS linkage debates by quantifying default-value exposure for the largest CBAM-covered exporter. Its MRV-under-disruption methodology offers lessons for ISSB/CSRD assurance in conflict-affected or data-fragmented jurisdictions.

📄 Abstract（原文）
Ukraine entered the definitive period of the EU Carbon Border Adjustment Mechanism (CBAM) in January 2026 as the largest exporter of CBAM-covered goods to the EU by physical volume, while its industrial base remains under direct wartime pressure. This study provides the first structural analysis of the open microaggregated dataset of the State Statistics Service of Ukraine (SSSU) on air pollutant and greenhouse gas emissions, covering 1990–2025 across 1284 territorial units, 128 substances, and 605 economic activities (NACE/KVED-2010). A documented harmonization procedure is proposed that resolves the 2020/2021 dimensional break and the ambiguity between oblast (region)- and hromada (municipality)-level records, yielding consistent 36-year series with independent national total validation for 2015–2025. Four phases are identified: transformational decline (1990–1999, −56.5%), stabilization (1999–2013, +4.6%), post-2014 structural decline (2013–2021, −47.9%), and the full-scale war shock (2021–2025, −55.0%). Stationary source emissions fell by 89.3% overall, but the wartime reduction reflects destruction and occupation of capacity, not decarbonization, as reflected in the collapse of metallurgy (−73.8%) and coke production (−89.6%) and the loss of the Mariupol district from statistical coverage after 2022. Mobile sources now supply 65% of the national total. Coal mine methane dominates stationary CH4 (301 kt in 2021; ≈9.0 Mt CO2 eq), directly relevant to Regulation (EU) 2024/1787. The regional Herfindahl–Hirschman index fell from 1847 (2021) to 1524 (2025), indicating war-driven regional deconcentration and a westward shift in the emission center of gravity. The findings are validated against independent satellite-based and conflict attribution estimates, and implications for monitoring, reporting and verification (MRV) infrastructure, CBAM default value exposure, and the phased design of Ukraine’s emissions trading system are derived.
