本研究は、2000年から2022年までのOECD32カ国のパネルデータを用いて、環境税と環境政策の厳格性がCO2排出量に与える影響を分析。結果、環境税の1%増加はCO2排出量を0.119%削減し、政策の厳格性の1%上昇は0.040%削減することが示された。再生可能エネルギーは排出削減に寄与する一方、都市化は排出を増加させる。環境クズネッツ仮説も支持された。
English
This study analyzes the impact of environmental taxes and environmental policy stringency on CO2 emissions across 32 OECD countries from 2000 to 2022 using panel data. Results show that a 1% increase in environmental taxes reduces CO2 emissions by 0.119%, while a 1% increase in policy stringency reduces emissions by 0.040%. Renewable energy significantly reduces emissions, but urbanization increases them. The Environmental Kuznets Curve hypothesis is supported.

日本のGX文脈において
日本はOECD加盟国であり、環境税（地球温暖化対策税）や政策の厳格性の強化が排出削減に有効であることを示す本結果は、日本のGX・カーボンプライシング政策（GXリーグ、排出量取引制度）の設計に示唆を与える。
In the global GX context
This paper provides empirical evidence on the effectiveness of environmental taxes and policy stringency in reducing CO2 emissions across OECD countries, reinforcing the role of carbon pricing and regulatory frameworks in global climate policy (e.g., EU ETS, carbon taxes). It supports the EKC hypothesis and highlights the complementary role of renewable energy.
👥 読者別の含意
🔬研究者:Provides robust panel data evidence on the effectiveness of environmental taxes and policy stringency, useful for climate policy modeling.
🏛政策担当者:Confirms that environmental taxes and strict policies significantly reduce emissions, supporting the adoption of carbon pricing and regulatory stringency.
📄 Abstract（原文）
Effectively combating climate change is a critical objective in the twenty-first century, with rising global temperatures, extreme weather events, and environmental degradation having severe social and economic consequences, necessitating urgent policy actions. The current study examines the impact of environmental taxes and environmental policy stringency on CO 2 emissions in OECD countries, utilizing a balanced panel dataset of 32 OECD countries from 2000 to 2022. Additionally, this study incorporates key control variables, including renewable energy consumption, economic growth, financial development, urbanization, and human capital, to provide a comprehensive analysis. The empirical results reveal that 1% increase in environmental taxes leads to a 0.119% reduction in CO 2 emissions, while a 1% increase in environmental policy stringency results in a 0.040% decrease in CO 2 emissions. Renewable energy significantly reduces emissions, whereas urbanization contributes positively to CO 2 emissions. Using system GMM for robustness tests shows that environmental taxes and strict environmental policies can effectively improve the quality of the environment in OECD countries. Moreover, we categorized 32 OECD countries into two groups to address potential heterogeneity: low-emitting countries and high-emitting countries. Our empirical findings of these groups are consistent with the overall results. Finally, our empirical results support the EKC hypothesis by confirming an inverted U-shaped relationship between economic growth and CO 2 emissions across all models. Thus, we concluded that environmental taxes and strict environmental policies have a significant impact on CO 2 emissions among OECD countries.
