天然ガス価格の高騰が電力価格を押し上げ、石炭への切り替えや脱炭素政策の弱体化を招く問題を実証分析。ロシアのウクライナ侵攻後のガス価格ショックを利用し、13のEU諸国の時間別電力市場データからガス価格が石炭発電・CO2排出・電力価格に与える影響を推定。EUのガス価格上限の限界を示し、EU ETS内のルールベースの緊急メカニズムとして、ガス価格が歴史的基準を超えた際に自動発動する控えめなオークション予備価格が、消費者保護と脱炭素インセンティブ維持を両立することを提案。
English
This paper empirically analyzes how natural gas price spikes undermine climate policy by raising electricity prices, inducing coal switching, and prompting policy interventions. Using hourly data from 13 EU countries around the Russia-Ukraine war, it finds the EU gas price cap has limited effectiveness. It proposes a rule-based emergency mechanism within the EU ETS: a modest auction reserve price automatically triggered when gas prices exceed historical benchmarks, which can protect consumers while preserving decarbonization incentives.

日本のGX文脈において
日本では、エネルギー価格高騰時の電力市場と排出量取引の連携が重要な政策課題。本論文の提案するルールベースの緊急メカニズムは、日本のGX推進や電力市場設計に示唆を与える。
In the global GX context
This paper contributes to global carbon pricing scholarship by proposing a resilient emergency mechanism within the EU ETS, relevant for jurisdictions like the UK, California, and China that face similar gas price volatility and need to balance consumer protection with decarbonization.

📄 Abstract（原文）
Abstract Recurring surges in natural gas prices strain climate policy by raising electricity prices, inducing gas-to-coal switching, prompting discretionary interventions, and fueling pressure to weaken decarbonization. We develop an empirical framework that quantifies how gas price spikes compromise climate policy and provides a toolkit to assess emissions trading system responses based on environmental effectiveness and their capacity to limit high electricity prices. Exploiting the gas price shock following Russia’s invasion of Ukraine, we estimate the impacts of gas prices on coal generation, CO 2 emissions, and electricity prices across 13 EU countries using hourly electricity market data. We find that the EU’s gas price cap has limited effectiveness and instead propose a resilient rule-based emergency mechanism within the EU Emissions Trading System (EU ETS). A modest auction reserve price, automatically triggered when gas prices exceed historical benchmarks, can protect consumers while preserving decarbonization incentives and limiting the need for ad hoc interventions.
