自主的炭素市場（VCM）の森林プロジェクトのセーフガード提供を評価する枠組みを開発し、Verra登録プロジェクトに適用。取引データと結合し、セーフガードが強いプロジェクトほどクレジットの償却が速いかを検証。結果、市場は一貫して強いセーフガードを報酬とせず、一部のセグメントでのみ効果が見られた。透明性の高い開示と標準化された基準の重要性を示す。
English
This study develops a safeguard assessment framework for forest carbon projects and applies it to Verra-registered projects. Linking safeguard scores with transaction data, it finds little evidence that stronger safeguards lead to faster credit retirement, except in better-measured segments. The findings underscore the need for transparent disclosures and standardized safeguard criteria in voluntary carbon markets.

日本のGX文脈において
日本ではJ-クレジット制度が独自の認証を行うが、国際VCMの質評価は今後の市場参加に重要。本研究成果は、日本のプロジェクト開発者が国際基準に合わせたセーフガード情報開示を進める際の参考となる。また、カーボン・クレジットの品質評価に関する国際的な議論に日本の関係者が参加するための基礎知識を提供する。
In the global GX context
This paper contributes to global VCM integrity discussions, aligning with ICVCM and CORSIA efforts. It provides empirical evidence on the link between safeguards and market uptake, informing disclosure standards and rating initiatives. For global scholars, it offers a replicable framework for assessing safeguard provisions.

📄 Abstract（原文）
The voluntary carbon market (VCM) plays an increasingly important role in financing forest-based climate mitigation. However, the viability of this mechanism relies on project outcomes being commensurated into a single carbon metric (tCO₂e), which can obscure other social and environmental dimensions and, if neglected, lead to harm. Yet the evaluation of forest carbon projects’ provisions to ensure baseline environmental and social safeguards remains incomprehensive and fragmented. This limits market transparency and the ability to empirically assess whether safeguard provisions influence market behavior. To address this gap, this study develops a universal safeguard assessment framework composed of four overarching dimensions: Social, Environmental, Economic, and Governance, further broken down into 14 specific criteria. Applying this framework to Verra-registered forest projects, each project’s safeguard provision is measured quantitively from publicly available project documentation. These safeguard scores are then linked with transaction-level data to examine whether stronger safeguard provisions are associated with shorter trading life, which is the time from credit issuance to retirement, taken as a proxy for market uptake. Overall, we find little evidence that the market consistently rewards stronger safeguards. Signs of faster credit retirement appear only in better-measured segments, suggesting any reward is segment-specific rather than market-wide. These findings highlight the importance of improving VCM infrastructure with more transparent and comparable disclosures, standardized safeguard criteria, and credible safeguard rating or label. These improvements would facilitate more reliable market analyses and help align market incentives with high-integrity climate action
