2024年11月25日のNDC合同会合で事務局が提示した日本の排出削減目標案の根拠となったシナリオ分析について、世界全体の1.5℃目標とどのような関係にあるかを検討し、以下の点を指摘する。(1) 世界モデルで評価しているRITEのシナリオ分析に基づくと、排出削減経路として「上に凸」をとれば、日本の排出削減ペースは先進国だけでなく世界全体に比べても緩やかなものになる。 (2) 日本が直線的な削減経路をとった場合、国際合意の根拠となっている1.5℃目標に向けた世界の排出削減経路に比べて削減が遅くなる。 (3) 分析された、先進国は直線的削減かつ世界全体で1.5℃目標を維持しようとするシナリオは、世界全体での排出削減ペースが遅く、1.5℃目標達成に向けてリスクが大きい。
