本稿は欧州の主要8気候シナリオを14指標で比較し、需要削減と供給側依存のバランスを検証する。需要削減は気候野心・実現可能性・頑健性と正相関し、EU2040年目標設定に重要な示唆を与える。建物・モビリティの詳細前提では低需要CLEVERと欧州委員会S3を比較し、S3の傾向的投影とCLEVERの明示的エネルギーサービスモデリングの差を浮き彫りにする。
English
This study benchmarks eight major European climate scenarios using 14 indicators to assess how demand reduction versus supply-side options shape climate ambition. It finds demand reduction correlates positively with ambition, feasibility, and robustness, offering lessons for EU 2040 target setting. A detailed comparison of buildings and mobility assumptions contrasts the low-demand CLEVER scenario with the Commission's S3, revealing gaps in energy service modelling.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でも第7次エネルギー基本計画やGX2040ビジョンで需要側対策の重要性が増す中、欧州のシナリオ比較手法は省エネ政策・目標設定の参考になる。SSBJ開示とは直接関係しないが、長期脱炭素経路の頑健性評価に示唆。
In the global GX context
As global disclosure frameworks (ISSB, CSRD) increasingly demand forward-looking climate scenarios, this paper shows how scenario design choices around demand reduction affect perceived ambition and feasibility. It informs the EU 2040 target debate and offers a benchmark methodology applicable to other jurisdictions' transition planning.
👥 読者別の含意
🔬研究者:シナリオ比較の指標設計と需要削減の役割評価に関心のある研究者に有用。
🏢実務担当者:長期脱炭素戦略やシナリオ分析の前提見直しに活用できる。
🏛政策担当者:2040年目標設定や省エネ政策の設計において需要側対策の位置づけを再考する材料。
📄 Abstract（原文）
Extended abstract 3-288-26 While the role of energy demand reduction to meet climate objectives is increasingly considered, most scenarios do not fully reflect this potential, and only a few explore low-demand pathways. Literature reviews show that this is not only due to preferences of modellers or scenario users, but also to structural limitations of models.This analysis investigates how main energy and climate scenarios for Europe balance demand and supply-side options and how this is informing policy making, with a particular focus on the setting of EU 2040 targets. It first focuses on a comparison and benchmark of scenarios. Eight prominent scenarios by institutions, think tanks and an NGO are selected on criteria of comprehensiveness, detail of modelling and compliance with the Paris Agreement. They are then characterised using 14 indicators that reflect their outcomes (GHG budget, fossil fuel consumption) and their use of major levers (renewables, hydrogen, electrification, reduction of consumption, carbon sinks). These numbers are then compared to targets and thresholds drawn from reports on climate objectives and the potential of various options by the European Scientific Advisory Board on Climate Change (ESABCC). This benchmark of the relative ambition and feasibility of scenarios shows a positive correlation between demand reduction – compared to stronger reliance on supply-oriented options – and climate ambition, feasibility and robustness, providing major lessons for the EU’s 2040 target setting. The analysis then reviews detailed assumptions on energy demand for buildings and mobility, comparing the low-demand CLEVER scenario with the Commission's S3 – one of the few providing such detail. Beyond the transparency gap in data, this comparison reveals the prevalence in a scenario like S3 of trend-based projections of activity, contrasting with CLEVER’s explicit modelling of energy services. Analysing this gap can help to inform policies about the potential of energy savings. Read the full abstract. Download presentation.
