UNFCCCが2025年に合意した途上国向け気候資金目標（2035年までに3000億ドル）を、先進国での炭素価格収入で賄うシナリオを評価。産業化・移行・途上国で異なる炭素価格を想定し、2022年時点のNDC達成シナリオと比較して16%多い排出削減が可能と示す。しかし1.5℃目標に整合する削減にはなお資金ギャップがあり、より大規模な緩和行動が必要と結論。米国や中国が制度に参加しない場合の影響も追加シナリオで分析。
English
This study assesses a scenario where carbon pricing revenues in industrialized regions fund the UNFCCC's 2035 climate finance goal of USD 300 billion for developing countries. With differentiated carbon prices across industrialized, transition, and developing regions, the scenario achieves 16% more GHG reductions by 2035 than current NDCs (as of 2022). However, a significant revenue gap remains for aligning with a 1.5°C pathway, indicating the need for stronger mitigation actions. Additional scenarios highlight implications of excluding major emitters like the USA and China.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本はG7議長国として気候資金の動員に積極的であり、本研究成果は国際交渉における日本の立場形成に示唆を与える。また、国内の炭素価格導入（GX-ETS等）の効果を国際的な緩和貢献の観点から評価する上で参考になる。
In the global GX context
This paper provides quantitative evidence on the potential of carbon pricing to meet international climate finance goals, relevant to global debates on climate finance architecture and carbon pricing mechanisms. It informs discussions under the UNFCCC and G20 on enhancing mitigation ambition and the role of carbon markets.
👥 読者別の含意
🔬研究者:Provides a scenario framework linking climate finance targets to carbon pricing revenues and mitigation outcomes, useful for integrated assessment modeling.
🏢実務担当者:Offers insights into potential carbon price trajectories and their implications for corporate carbon costs and investment planning.

📄 Abstract（原文）
The United Nations Framework Convention on Climate Change (UNFCCC) agreed in 2024 to boost finance for climate change in developing countries to USD 300 billion by 2035. In this study, we assess how much mitigation of greenhouse gases (GHGs) is possible by generating this amount of revenues from carbon pricing in industrialized regions. We assess a scenario that considers carbon prices differentiated for industrialized, transition and developing regions. We find that such scenario provides 16% more GHG emissions reductions by 2035 compared to a scenario where the existing national mitigation targets (represented by the Nationally Determined Contributions as of 2022) are achieved. Despite this, a considerable gap remains in terms of the revenues needed to achieve emissions reductions aligned with a pathway securing the climate target of 1.5oC global warming above pre-industrial levels. Therefore, these outcomes suggest that considerably larger climate mitigation actions are needed beyond the climate finance goal agreed by nations under the UNFCCC. In addition, we highlight by means of additional scenarios the implications (in terms of emissions reductions, carbon price revenues and consumption losses) of the absence in the carbon pricing scheme of the major GHG emitters from industrialized regions (USA) and from developing regions (China).
