本論文は、民主主義の度合いとCO2排出量の関係を、複数の民主主義指標と様々な計量手法を用いて包括的に分析した。その結果、長期的な民主主義の高さは一人当たりCO2排出量の低下と一貫して関連し、特に高所得国でその効果が顕著であることが示された。低所得国では効果が弱く、経済発展と行政能力の重要性が示唆される。この結果は、従来の混合した証拠を整理し、民主主義と気候の関係の理論的理解を進めるものである。
English
This paper comprehensively analyzes the relationship between democracy and CO2 emissions using multiple democracy indices and various panel methods. It finds that higher long-run democracy is consistently associated with lower per capita CO2 emissions, especially in high-income countries. The effect is weaker in low-income countries, highlighting the importance of economic development and administrative capacity. The findings reconcile previously mixed evidence and advance theoretical understanding of the democracy-climate nexus.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は高所得民主主義国であり、本論文の知見は日本の気候政策に示唆を与える。長期的な民主的制度の維持が排出削減に寄与する可能性を示し、SSBJや政策連動の議論にも関連する。ただし、日本の文脈では経済発展度合いがすでに高いため、追加的な政策効果の検証が必要である。
In the global GX context
This paper provides robust empirical evidence that democratic institutions facilitate climate mitigation in high-income countries, reconciling mixed prior results. It contributes to global climate policy debates by emphasizing the role of economic development and administrative capacity. The findings are relevant for ISSB/TCFD framework discussions on enabling conditions for effective climate action.
👥 読者別の含意
🔬研究者:This paper offers rigorous empirical evidence on the democracy-climate nexus using multiple indices and methods, advancing the theoretical understanding of institutional conditions for climate mitigation.
🏛政策担当者:The findings highlight that enduring democratic institutions, supported by economic development, can enhance climate policy effectiveness, informing the design of institutional frameworks for emission reductions.
📄 Abstract（原文）
<p>The impact of democracy on climate change mitigation remains contested, as empirical findings are mixed. This inconsistency may stem from prior studies relying on single democracy measures and narrow model specifications, leaving the true democracy-climate relationship unclear. We address these limitations by conducting a comprehensive panel analysis with multiple democracy indices and advanced estimators. Specifically, we employ six distinct democracy indices and various time-series cross-sectional methods (including panel-corrected standard errors, fixed effects [FE], and a random effects within-between [REWB] model) to separately capture long-run (structural) democracy and short-run changes. Our findings show that higher long-run levels of democracy are consistently associated with lower carbon dioxide (CO₂) emissions per capita. This negative association is especially pronounced in high-income countries and significantly weaker in low-income countries. Moreover, the results remain robust across different model specifications and sensitivity checks, including outlier exclusions and temporal lags. These findings suggest that enduring democratic institutions can facilitate climate mitigation, but only when supported by sufficient economic development and administrative capacity. Taken together, the results reconcile previously mixed evidence and advance theoretical understanding of the democracy-climate nexus.</p>
