日本語

本研究は、メタン削減プロジェクトにおけるMRV体制の設計がカーボンクレジットの発行量や価格に与える影響を分析した。強化されたMRVにより、保守的な発行可能割合が77.0％～91.3％に改善し、価格格差が0.30から0.12に縮小した。また、モニタリングから発行までの期間が50日短縮された。

English

This study analyzes how MRV system design affects carbon credit outcomes in a methane abatement project. With enhanced MRV, the conservatively supportable credit fraction improved to 77.0%–91.3% and the price wedge declined from 0.30 to 0.12. The monitoring-to-issuance period shortened by 50 days.

🏛政策担当者:Regulators can apply the insights to strengthen carbon credit integrity standards.

📄 Abstract（原文）

The research analyzes whether monitoring system design, calibration management, timestamp consistency, data traceability, and verification procedures relate to the risk control of the financial aspects of methane-abatement engineering projects.An analytical case study based on a single project and involving a before-and-after comparison of the implementation of an monitoring, reporting, and verification (MRV) regime was conducted under fixed engineering and accounting conditions.This design allows the comparison to focus on differences in MRV evidence management conditions rather than on changes in physical mitigation technology.Conservative issuability was estimated using the low-confidence adjustment metric (LCAM).This analytical metric scales engineering emission reductions by evidence-related factors without supplanting registry rules or verifier judgment.With the enhanced MRV regime, the conservatively supportable fraction was 77.0% to 91.3%, while the realized price wedge declined from 0.30 to 0.12.The monitoring-to-issuance period was also shortened by 50 days.
