🤖 gxceed AI 要約
日本語
本データセットは、産業連関表と環境拡張表を用い、71経済・927部門について輸出に体化された温室効果ガス排出が国内付加価値と等しくなる炭素価格（P*）を算出した複製パッケージである。従来の総輸出ベース閾値（P^gross）は付加価値シェアの逆数分だけ過大評価となることを示し、その過大評価係数も提供する。
English
Replication package computing, for 927 economy-sector pairs across 71 economies, the carbon price at which embodied export emissions equal retained domestic value added (P*). It shows the conventional gross-export threshold overstates the true threshold by the inverse of the domestic value-added share, and provides that share and overstatement factor.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
炭素国境調整措置（CBAM等）や輸出産業の炭素コスト負担を付加価値ベースで再評価する視点を提供し、日本企業の輸出競争力・Scope3対応やSSBJ開示における体化炭素の扱いに示唆を与える。
In the global GX context
Speaks directly to CBAM and carbon-border-adjustment debates by showing that gross-export-based embodied carbon thresholds overstate liability; relevant to ISSB/CSRD Scope 3 and transition-finance discussions on where carbon costs actually fall.
👥 読者別の含意
🔬研究者:付加価値ベースの体化炭素指標と複製可能なデータで、炭素価格・貿易・排出責任の実証研究に活用できる。
🏢実務担当者:輸出に伴う体化炭素コストを付加価値基準で把握し、CBAM対応やサプライチェーン開示の優先部門を判断する材料になる。
🏛政策担当者:炭素国境調整や炭素価格設計で、総輸出ではなく付加価値基準の閾値を用いる政策的含意を検討すべき。
📄 Abstract（原文）
This dataset is the replication package for “Embodied Carbon Liability: Value Added, Not Gross Output” (W.-T. Fang, submitted to Ecological Indicators). It reports, for 927 economy–sector pairs in 71 economies in 2023, the carbon price at which the greenhouse gas emissions embodied in a sector’s exports would equal the domestic value added those exports retain (P*), together with the conventional threshold defined against gross exports (P^gross) and a variant that counts only domestically released emissions (P*dom). Because the conventional threshold exceeds the corrected one by exactly the inverse of the domestic value-added share, the file also gives that share (v) and the resulting overstatement factor (1/v) for every pair. Value added and emissions are drawn from one accounting system: the Asian Development Bank multiregional input–output table for 2023 (74-economy edition, July 2025 release) and its environmentally extended air-emissions table (version of 1 August 2025; CO2, CH4, N2O and F-gases weighted by AR5 GWP100). The source tables are not redistributed; they are available from the ADB Key Indicators Database. Contents: data/thresholds_2023.csv: thresholds, value-added shares, embodied emission multipliers and gross exports for each economy–sector pair (variables and units defined in README.md) data/summary_results_2023.json: every summary statistic reported in the paper data/economy_codes.json: ADB economy codes and names code/: Python scripts that extract the tables, compute the indicators, draw the figures and check the manuscript Figure_1.png, Figure_2.png: the published figures at 600 dpi Data are released under CC BY 4.0 and code under the MIT License.
