GHGプロトコル、ISO 14064、IPCCガイドラインという三大炭素会計フレームワークと、パリ協定などの国際気候協定との整合性を検討する研究。2024年に世界排出量が53.2GtCO2eと過去最高を記録する中、報告数値の信頼性・比較可能性が協定の実効性を左右すると指摘する。フレームワーク間の「言語の不一致」が透明性ある報告と目標進捗を妨げており、企業・国家・国際レベルでの標準化・調和が政治的約束を測定可能な数値に変える鍵だと論じる。
English
This study examines how the three dominant carbon accounting frameworks—the GHG Protocol, ISO 14064, and IPCC Guidelines—align with international climate agreements like the Paris Agreement. With global emissions hitting a record 53.2 GtCO2e in 2024, it argues that trustworthy, comparable reported numbers are what make treaties effective. The mismatch in 'language' across frameworks undermines transparent reporting and target progress; harmonizing accounting across corporate, national, and international levels is key to turning political commitments into measurable figures.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
SSBJ基準や有報でのGHG開示が進む日本企業にとって、GHGプロトコルとISO・IPCCの整合性はScope算定の根幹に関わる。国際協定との接続を意識した開示設計の参考になる。
In the global GX context
Directly relevant to the ISSB/CSRD push for interoperable emissions reporting: it frames why harmonizing GHG Protocol, ISO, and IPCC conventions matters for making TCFD/ISSB disclosures comparable and treaty-aligned.

📄 Abstract（原文）
Climate change is, by now, one of the defining tests of our time, and no country can pass that test on its own. The numbers make the point starkly: global greenhouse gas emissions hit a record 53.2 gigatonnes of carbon dioxide equivalent in 2024, about 1.3% above the year before (Crippa et al., 2025), reminding us how far off course the world still is. Agreements like the Paris Agreement exist precisely to coordinate the response, but they only work if the carbon accounting underneath them holds up; that is, if the numbers different countries and companies report can actually be trusted and compared. Three frameworks do most of the heavy lifting in practice: the Greenhouse Gas (GHG) Protocol, ISO 14064, and the IPCC Guidelines. The trouble is that these frameworks and the treaties they are supposed to serve do not always speak the same language, and that mismatch is precisely what makes transparent reporting, and real progress on climate targets, harder than it needs to be. This study asks a fairly simple question with a complicated answer: could standardizing carbon accounting further make international climate agreements work better? Carbon accounting is the toolkit governments and companies use to quantify, report, and verify their emissions, which puts it, whether we notice or not, at the very center of global climate governance. Get the harmonization right across corporate, national, and international levels, and political commitments stop being promises on paper and start becoming numbers that can actually be measured and compared.
