OECD31カ国を対象に、炭素税と排出権取引制度（ETS）がCO2排出に与える影響を動的パネル分析で検証。単独では有意な効果はないが、低炭素エネルギーの普及と組み合わせることで排出削減効果が顕著になることを示した。政策ミックスの重要性を強調。
English
This study assesses the impact of carbon taxes and emissions trading systems (ETS) on CO2 emissions in 31 OECD countries using a dynamic panel approach. It finds that neither instrument alone significantly reduces emissions, but combining them with increased low-carbon energy penetration leads to substantial emission reductions. The findings highlight the need for integrated policy mixes that combine carbon pricing with structural and technological transformations.

日本のGX文脈において
日本でもカーボンプライシングの導入が議論される中、本論文は炭素税やETSを単独で導入するだけでは不十分であり、低炭素エネルギー普及やエネルギー効率改善と組み合わせた政策ミックスが重要であることを示している。日本のGX推進政策の設計に示唆を与える。
In the global GX context
This paper provides empirical evidence that carbon pricing instruments (taxes and ETS) are more effective when combined with policies promoting low-carbon energy and energy efficiency. This is highly relevant for global policy debates on carbon pricing design, including the EU ETS, UK carbon tax, and emerging systems in Asia and the Americas.
👥 読者別の含意
🔬研究者:Provides empirical evidence on the limited effectiveness of standalone carbon pricing and the importance of policy mix, useful for further research on policy interaction.
🏢実務担当者:Helps corporate sustainability teams understand the policy context in which carbon pricing operates and the need to combine internal carbon pricing with clean energy investments.
🏛政策担当者:Key finding that carbon taxes and ETS alone may not reduce emissions; complementary measures like low-carbon energy deployment are essential for effectiveness.
📄 Abstract（原文）
Achieving sustainability requires a coherent policy mix to address the climate change problem. To internalize the cost of carbon emissions resulting from the existing mode of production, central market-based mechanisms, such as carbon taxes and emissions trading systems (ETS), can be applied. Nevertheless, structural and technological context may affect their effectiveness. In this context, the present study tries to assess the impact of carbon pricing instruments on CO2 emissions while explicitly accounting for the structural and technological framework by integrating energy intensity and the usage of low-carbon energy in the energy mix, using a dynamic panel approach based on the Generalized Method of Moments for 31 OECD countries over the period 1997-2020. The results show that the implementation of carbon taxes or ETS does not have a statistically significant impact on emission reductions. However, combining the two instruments alongside a higher penetration of low-carbon energy sources leads to a significant decline in emissions. These findings suggest that the effectiveness of economic instruments should be combined with complementary structural and technological transformations. An integrated policy mix that simultaneously promotes energy efficiency and accelerates the transition toward low-carbon energy systems may be embedded with carbon pricing.
