本レビューは、素材使用の持続可能性目標（SBT）に関する文献（2000〜2025年）と欧州の政策文書を統合し、目標設定の3つのアプローチ（回顧的境界、資源利用可能性、影響ベース）を特定した。影響ベースのアプローチが主流となりつつあり、政策目標は戦略的で非拘束的、経済全体の指標に焦点を当てている。素材SBTの透明な分析的根拠の必要性を強調する。
English
This review synthesizes literature (2000–2025) on science-based targets for material use and European policy documents, identifying three approaches: retrospective boundaries, materials availability, and impact-based. Impact-based approaches dominate, while policy targets are strategic, non-binding, and economy-wide. It argues for transparent analytical rationale in material SBTs.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では、SSBJ開示や循環経済政策が進む中、素材使用のSBTはまだ未整備。本レビューの3アプローチは、日本企業が資源効率目標を設定する際の枠組みとして参考になる。特に、影響ベースのアプローチは、気候変動と資源利用を統合した目標設定に有用。
In the global GX context
Globally, this review informs the ongoing discourse on science-based targets beyond climate, aligning with ISSB and CSRD expectations for broader sustainability disclosure. It provides a taxonomy of approaches that can help standardize material-use targets, supporting transition finance and circular economy policies.
👥 読者別の含意
🔬研究者:Provides a systematic taxonomy of material SBT approaches, useful for further research on target-setting methodologies.
🏢実務担当者:Offers a framework for companies to set credible material-use targets, aligning with emerging disclosure requirements.
🏛政策担当者:Highlights the heterogeneity of European material targets, suggesting a need for harmonization and clearer analytical grounding.
📄 Abstract（原文）
Science-based targets (SBTs) are increasingly proposed to align raw material use with environmental and societal goals, yet no consensus exists on what constitutes sustainable levels of material use. This paper reviews the scientific literature on material-use targets (2000–2025) and combines it with a dedicated survey of resource-use and circular-economy targets in European policy documents. Three main approaches to setting material targets are identified: retrospective boundaries based on historically “safe” extraction levels; materials availability focusing on the accessibility and availability of resources; and impact-based approaches that derive targets from planetary boundaries or from the material requirements of sustainability scenarios. Impact-based approaches have become most prominent, supported by advances in scenario analysis, while retrospective boundaries remain influential in policy debates. The European policy inventory reveals widespread but highly heterogeneous material and wider resource targets, with target-rich countries coexisting alongside those with only a few commitments. Most targets are strategic and non-binding, centered on economy-wide indicators (e.g., material footprints or circular use rates), with fewer sectoral or sub-national targets and substantial variation in baselines, reference years, and accounting perspectives. The paper argues that SBTs for materials should be grounded in a transparent analytical rationale explicitly linked to one of the three approaches.
