欧州35カ国（33のNECPとノルウェー・スイス）の国家エネルギー・気候計画をLEAPモデルで共通フレームに落とし込み、全面実施を仮定した「国家約束（NC）シナリオ」を構築した。NCシナリオではエネルギー由来GHGは2025〜2050年に約65%削減されるが、各国計画の合算は2050年に電力115TWh・グリーン水素79TWhの純輸入を前提とし、供給側計画と整合しない。計画間の時間軸・野心度・データ粒度・燃料貿易前提のばらつきを整理し、部門・国別の政策提言を示す。
English
The authors simulate 35 European national energy and climate plans (33 NECPs plus Norway and Switzerland) in a common LEAP modeling framework, building a consolidated National Commitments scenario assuming full implementation. Energy-related GHG emissions fall ~65% from 2025 to 2050 across all sectors, driven by efficiency and cleaner fuel mixes. Yet the plans are mutually inconsistent: summed, they imply 2050 net imports of 115 TWh electricity and 79 TWh green hydrogen that no European plan supplies. The paper maps divergences in timelines, ambition, data granularity and fuel-trade assumptions, and offers sector- and country-tailored policy recommendations.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でもエネルギー基本計画・NDC・GX推進戦略の整合性検証が課題であり、複数計画を共通モデルで突合し供給不足を可視化する手法は、国の計画策定・レビュー体制の参考になる。
In the global GX context
Directly relevant to the global stocktake and NDC ratchet: it demonstrates a replicable method for testing whether aggregated national plans are internally consistent, exposing electricity and hydrogen import gaps that disclosure and transition-finance frameworks increasingly need to price.
👥 読者別の含意
🔬研究者:各国計画を共通モデルで比較・集約する手法と、計画間不整合の定量化アプローチを参考にできる。
🏢実務担当者:欧州事業を持つ企業は、電力・グリーン水素の輸入前提ギャップをサプライチェーン・調達リスク評価に反映すべき。
🏛政策担当者:国別計画の野心度・時間軸のばらつきと供給整合性を点検するレビュー手法として、NDC・エネルギー計画策定に示唆がある。
📄 Abstract（原文）
Achieving climate neutrality in Europe is a critical goal, yet there is no model-based assessment detailing the key factors and assumptions of each Member State’s National Energy and Climate Plan (NECP). To fill that gap, the plans of 35 European countries (33 NECPs and the equivalent national plans of Norway and Switzerland) were reviewed, and each was simulated in a common energy emissions modeling framework, creating a consolidated European National Commitments (NC) scenario that assumes full implementation of the plans. The LEAP (Low Emissions Analysis Platform) model developed for this purpose covers energy consumption and production in the residential, industrial, agricultural, transport (terrestrial, maritime, aviation), and services sectors. Greenhouse gas emissions are calculated in CO2 equivalents for each fuel type and end use. Under the NC scenario, energy-related GHG emissions fall by about 65% between 2025 and 2050, with reductions in all sectors, driven by energy efficiency gains and cleaner fuel mixes. Yet the plans are not mutually consistent: summed over all countries, they imply net imports of 115 TWh of electricity and 79 TWh of green hydrogen in 2050 that no European plan foresees supplying. However, achieving these reductions depends on fully implementing 35 plans, which vary substantially in their timelines, ambition levels, data granularity, and fuel trade assumptions. The paper discusses these inconsistencies and proposes policy recommendations tailored by sector, country, and policy framework to support a holistic and equitable transition.
