本研究は、韓国がCOP28で約束した再生可能エネルギー容量の2030年までの3倍増と原子力容量の2050年までの3倍増を、IPCC AR6シナリオデータベースを用いて評価した。分析の結果、韓国の現行電力計画はパリ協定に沿った経路と比較して化石燃料の段階的廃止が遅く、再生可能エネルギー目標は多くのシナリオと整合する一方、原子力目標は大半の長期経路と矛盾することが示された。
English
This study evaluates Korea's COP28 pledges to triple renewable capacity by 2030 and nuclear capacity by 2050 against IPCC AR6 scenarios. It finds that Korea's current electricity plan has a slower fossil fuel phase-out than Paris-aligned pathways. While the renewable tripling target aligns well with global decarbonization scenarios, the nuclear tripling target is inconsistent with most long-term pathways.

日本のGX文脈において
日本のGX政策においても原子力と再エネの役割が議論される中、本論文は科学的シナリオ分析に基づく政策整合性評価の重要性を示唆する。SSBJや有報での非財務情報開示においても、気候関連シナリオ分析の質が問われる局面で参考となる。
In the global GX context
This paper demonstrates a quantitative method to assess national energy pledges against IPCC scenarios, offering a template for evaluating policy coherence with global decarbonization goals. For countries like Japan considering both nuclear and renewable expansion, it provides evidence-based insights for scenario analysis and disclosure under TCFD/ISSB frameworks.
👥 読者別の含意
🔬研究者:Provides a replicable methodology for comparing national energy targets with IPCC scenario ensembles.
🏛政策担当者:Highlights the need for science-based scenario analysis to ensure energy policy alignment with Paris goals.
📄 Abstract（原文）
Summary At COP28, the international community, including Korea, committed to tripling renewable energy capacity by 2030 and nuclear capacity by 2050. These pledges are embedded within Korea’s carbon neutrality framework and the 11th Basic Plan for Long-Term Electricity Supply and Demand. This study examines the consistency of Korea’s clean energy policies with Paris-compliant trajectories derived from the IPCC AR6 scenario database. Our analysis demonstrates that Korea’s current electricity plan exhibits a slower phase-out of fossil fuel capacity relative to Paris-aligned pathways. Moreover, while the renewable energy tripling target demonstrates strong alignment with global decarbonization scenarios, the majority of IPCC AR6 models project constrained nuclear expansion, rendering the nuclear tripling pledge inconsistent with prevalent long-term pathways. As Korea advances its energy transformation, enhanced science-based modeling and rigorous scenario analysis are imperative to ensure policy coherence with global decarbonization objectives and support evidence-informed decision-making.
