日本語
EU電池規則の炭素フットプリント算定におけるデータ集約と多機能性処理の手法を比較分析した。多機能性処理の違いでセル当たり気候変動影響が約6%、時間的集約で±10%変動する。報告用には高い集約、エンジニアリング用には低い集約が適し、カットオフ適用を最も透明で一貫した手法として推奨する。標準化LCAの更なる明確化と目的別手法拡張を提唱する。
English
This study analyzes gaps in carbon footprint calculation under the EU Batteries Regulation, focusing on data aggregation and multifunctionality handling in battery cell production. Multifunctionality approaches cause ~6% difference in climate impacts per cell, while temporal aggregation varies results by ±10%. It recommends cut-off at end-of-life as most transparent and advocates extending LCA methods for distinct purposes like reporting and engineering.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
EU電池規則の炭素フットプリント算定は、日本企業が欧州向け電池・EV輸出で対応を迫られる制度。SSBJや有報でのScope3開示、製品別炭素会計の精緻化に直結し、国内電池メーカー・自動車メーカーの輸出競争力に影響する。
In the global GX context
The EU Batteries Regulation mandates carbon footprint declarations for batteries, setting a precedent for product-level carbon accounting under CBAM and other disclosure regimes. This paper highlights methodological ambiguities that global standard-setters (ISO, ISSB) must resolve for consistent cross-border comparability.

📄 Abstract（原文）
Abstract By enabling carbon footprint reporting and supporting engineering of batteries and their production, life cycle assessment (LCA) is essential for a sustainable energy and mobility transition. This article analyses current gaps and limitations in the carbon footprint calculations as part of the EU Batteries regulation, focusing on data aggregation and multifunctionality handling in the battery cell production. Different approaches to data aggregation and multifunctionality handling are identified. Their implications are identified and discussed based on the application in a case study. Different approaches to handling multifunctionality cause about 6% difference in climate change impacts per cell in the case study. Applying cut-off at end-of-life is recommended as the most transparent and consistent approach. Temporal data aggregation affects the climate change impacts per cell by ±10%, with higher aggregations being more suitable for reporting and lower aggregations being essential for engineering purposes. Spatial data aggregation does not affect the overall climate change impacts but influences hotspot identification. The study underlines the need for further clarification in the standardised LCA regarding multifunctionality handling and data collection. Further, this article advocates for an extension of the method tailored to different LCA purposes, such as reporting and engineering.
