本研究は、OECD5カ国（デンマーク、フィンランド、スウェーデン、ノルウェー、スロベニア）を対象に、1990～2019年のデータを用いて炭素税が温室効果ガス排出に与える効果を分析した。ピアソンの相関係数とPhillips-Perron単位根検定を採用した結果、フィンランド、スロベニア、スウェーデン、デンマークでは炭素税が排出削減に有効だったが、ノルウェーでは石油・ガス産業の拡大により効果が見られなかった。各国の経済・環境特性に合わせた炭素価格政策の重要性を示唆している。
English
This study examines the effect of carbon taxes on greenhouse gas emissions in five OECD countries (Denmark, Finland, Sweden, Norway, Slovenia) from 1990 to 2019. Using Pearson correlation and Phillips-Perron unit root tests, it finds that carbon pricing significantly reduced emissions in Finland, Slovenia, Sweden, and Denmark, but was ineffective in Norway due to expanding oil and gas sectors. The results highlight the need for country-specific carbon pricing policies.

日本のGX文脈において
本論文は国際的な炭素価格政策の実証分析であり、日本が導入を検討する炭素税やGXリーダー（排出量取引制度）の設計において、産業構造の違いによる効果の差を考慮する重要性を示す。日本の政策担当者は、ノルウェーの事例から資源輸出型経済における炭素価格の限界を学ぶことができる。
In the global GX context
This paper provides empirical evidence on the effectiveness of carbon taxes across different national contexts, directly relevant to global carbon pricing debates. It underscores that carbon pricing alone may be insufficient in resource-exporting economies, contributing to the design of more nuanced climate policy frameworks such as the EU's CBAM and the ongoing ISSB disclosure standards on transition plans.
👥 読者別の含意
🔬研究者:Provides empirical evidence on carbon tax effectiveness across different national contexts, useful for policy evaluation research.
🏢実務担当者:Supports corporate strategy teams in understanding how carbon pricing impacts emissions across diverse economies, aiding in transition risk assessment.
🏛政策担当者:Highlights the need for tailored carbon pricing mechanisms that account for industry structure, directly informing national climate policy design.
📄 Abstract（原文）
This study aims to understand the impact of carbon pricing on greenhouse gas emissions. It is necessary to evaluate the effectiveness of the carbon pricing mechanism on the ground level; therefore, this study provides valuable input about the policies of carbon taxes in OECD countries. This study examines the effects of carbon prices on greenhouse gas emissions in five OECD nations (Denmark, Finland, Sweden, Norway and Slovenia), for the sample period of 1990–2019. The research employs Karl Pearson's correlation and the Phillips–Perron Unit root test to analyze the relationship between carbon prices and greenhouse gas emissions across these countries. This study explores the relationship between carbon tax and greenhouse gas emissions, revealing mixed outcomes. Carbon pricing has significantly reduced emissions in Finland, Slovenia, Sweden and Denmark but has been ineffective in Norway, where emissions increased, likely due to the country's expanding oil and natural gas sectors. These findings highlight the limitations of carbon pricing in certain contexts and emphasize the need for national carbon pricing policies tailored to each country's unique economic and environmental characteristics to ensure effectiveness. This research highlights the need for tailored carbon pricing schemes that account for each country's unique environmental and economic conditions. It calls for further studies on the long-term impact of carbon pricing across sectors and regions. The study suggests combining technological innovation, behavioral economics and environmental policies to enhance carbon tax effectiveness, offering valuable insights for governments shaping carbon pricing strategies.
