廃棄物発電施設(ロンドン・エドモントンEcoPark)のカーボンフットプリントを事例に、アクターネットワーク理論を用いてLCAのシステム境界設定を関係的に再構成する方法を提案。22のアクターと技術要素を追跡し、境界決定の根拠と結果への影響を台帳化。計算の完全な再現性を確保したデータセットを公開し、LCAの透明性・説明責任向上に貢献する。
English
Proposes a relational LCA method that uses actor-network theory to set system boundaries, applied to the carbon footprint of London's contested Edmonton EcoPark energy-from-waste plant. It traces 22 actors and technical elements, logging every boundary decision, its rationale, and its effect on results. The open dataset enables full reproduction of all calculations, advancing transparency and accountability in carbon accounting.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
Scope 3や製品炭素足跡の算定境界は日本企業のSSBJ・有報開示でも論点となる。境界設定の恣意性を可視化・台帳化する本手法は、国内のLCA・カーボンフットプリント開示の説明責任強化に示唆を与える。
In the global GX context
System-boundary choices are a persistent source of inconsistency in Scope 3 and product carbon footprint disclosure under GHG Protocol, ISSB, and CSRD. This work offers a documented, auditable method for justifying boundaries, directly relevant to disclosure-infrastructure debates on comparability and greenwashing risk.
👥 読者別の含意
🔬研究者:LCAの境界設定における主観性を扱う方法論として、炭素会計研究の透明性議論に援用できる。
🏢実務担当者:製品・施設のカーボンフットプリント算定で境界選択の根拠を文書化する実務テンプレートとして活用可能。
🏛政策担当者:炭素算定の境界設定ルール策定や第三者検証の枠組み設計に、説明責任の観点から示唆を与える。
📄 Abstract(原文)
This dataset supports the manuscript "Relational life cycle assessment: an actor-network approach to system boundary setting in the inventory model, applied to the carbon footprint of a contested waste-to-energy plant". It documents the case study of the Edmonton EcoPark energy-from-waste facility in London, with all values expressed per tonne of residual municipal solid waste treated. The spreadsheet files contain the study's main records: the register of the 22 traced actors and technical elements with their roles, contestation flags, and documentary sources (Appendix A); the contested-actor documentation and the decision ledger recording every boundary decision, its rationale, and its effect on the result (Tables 2 and 3); the inventory calculations for the conventional screening and the two assessment scenarios (Tables 4 and 5); and two step-by-step calculation files, one of them a workbook with live formulas, so that every reported value can be reproduced from the documented inputs using a standard spreadsheet application. The CSV and Excel files are the original working records cited in the paper: the probe logs behind the boundary stopping rule; the threshold sensitivity records behind Figure 6; the omission-bound check; the re-derivation of the commissioned baseline; the parameter-level provenance list identifying which inputs come from source documents and which are declared demonstration parameters; and the consistency, traceability, and reliability checks. All values match the revised manuscript. Where a value is a declared demonstration parameter or an illustrative placeholder, the file itself says so. No executable code is included, and none is needed to verify the calculations. Records of exploratory analyses not reported in the manuscript are deliberately excluded, so that this archive corresponds exactly to the published claims.
