35のOECD諸国を1990-2019年まで分析し、CO2排出の決定要因を検証。GDPと化石燃料消費は排出を増加させる一方、グリーン技術革新と再生可能エネルギーは削減に寄与。環境税は有意な効果を示さず、制度設計の改善が必要。
English
This study analyzes CO2 emission drivers in 35 OECD countries (1990-2019). GDP growth and fossil fuel consumption increase emissions, while green innovation and renewable energy reduce them. Environmental taxes show insignificant positive effects, suggesting design improvements are needed.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本はOECD加盟国であり、グリーンイノベーションや再生可能エネルギー政策が排出削減に有効であることが示唆される。環境税の効果が限定的である点は、日本の炭素税制度の再検討にも示唆を与える。
In the global GX context
This paper provides empirical evidence from OECD countries that green innovation and renewables are effective for decarbonization, while reinforcing that environmental tax design matters. It contributes to the global debate on policy mix for emission reductions.
👥 読者別の含意
🔬研究者:Provides panel econometric evidence on the interplay of innovation, renewables, and carbon taxes in OECD decarbonization.
🏢実務担当者:Corporate sustainability teams can use findings to justify investments in green innovation and renewable energy as carbon reduction strategies.
🏛政策担当者:Highlights the need to complement carbon taxes with innovation and renewable policies for effective emission cuts; tax design requires careful consideration of overlapping schemes.
📄 Abstract（原文）
This article explores the key factors influencing carbon dioxide (CO 2 ) emissions in 35 OECD countries from 1990 to 2019. The analysis considers economic growth gross domestic product (GDP), green technological innovation (GTI), renewable energy consumption (REC), fossil energy consumption (FEC), and environmental taxation (ETAX). The study period captures the effect of major climate agreements and energy policy changes while avoiding distortions from post-2019 events such as the COVID-19 pandemic. To ensure reliability, the study applies panel econometric techniques that correct for cross-sectional dependence, heterogeneity, and endogeneity. The findings reveal that GDP growth and fossil fuel reliance raise emissions, whereas technological innovation and renewable energy reduce them. Environmental taxes show a positive but insignificant impact, possibly due to overlapping schemes like emissions trading, renewable subsidies, and tax exemptions for heavy industries. These results highlight the need to strengthen the design of environmental tax systems while promoting innovation and clean energy to achieve long-term emission cuts. The evidence contributes to understanding the drivers of CO 2 emissions in OECD economies and supports the formulation of integrated energy and climate policies.
