G7諸国を対象に、CO2排出の決定要因をパネル回帰と国別回帰で分析。エネルギー消費が主要因で、技術革新はパネル全体では排出削減に寄与するが国別では有意でない。都市化は米国でのみ削減効果、工業化は日本で削減効果。脱炭素にはクリーンエネルギー移行と国別のイノベーション政策が重要と示唆。
English
This study analyzes determinants of CO2 emissions in G7 countries using panel and country-specific regressions (1997-2023). Energy consumption is a robust driver; technological innovation reduces emissions at panel level but not consistently across countries. Urbanization mitigates only in the US, industrialization reduces emissions in Japan. Findings emphasize clean energy transition and tailored innovation policies.

📄 Abstract（原文）
Rising CO 2 emissions remain a major sustainability challenge, particularly in advanced economies that account for a considerable share of historical emissions. This study examines the key determinants of CO₂ emissions in G7 countries by jointly considering globalisation, energy consumption, urbanisation, industrialisation, and technological innovation. Using a balanced panel dataset for Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States over the period 1997–2023, the analysis applies panel regression techniques and country-specific multiple linear regressions to capture both common effects and heterogeneity across economies. The results indicate that energy consumption is a robust driver of CO₂ emissions across the G7. Technological innovation contributes to emission reduction at the panel level; however, its effect becomes statistically insignificant in country-specific estimations, reflecting cross-country differences in innovation structures and policy environments. Globalisation significantly increases emissions in Canada, while its influence is negligible elsewhere. Urbanisation shows a mitigating effect only in the United States, and industrialisation increases emissions in Canada and Italy but reduces emissions in Japan. Overall, the findings highlight that decarbonisation strategies in advanced economies should prioritise the transition to clean energy while strengthening innovation-oriented climate policies tailored to country-specific contexts.
