1990年から2017年にかけて世界各国で段階的に導入された炭素価格政策が、化石燃料燃焼による一人当たりCO2排出量に与える影響を推定。治療効果の不均一性に頑健な計量経済手法を用い、導入後10年で排出量が19〜23%減少することを示した。効果は主に資源代替によるもので、エネルギー効率改善や短期的な価格反応によるものではない。再生可能エネルギー政策の影響を制御しても結果は頑健で、炭素価格が中期的期待を形成し気候政策ミックスを補完する役割を強調する。
English
This study estimates the effect of staggered carbon pricing adoption globally (1990-2017) on per capita CO2 emissions from fossil fuels, using econometric methods robust to treatment effect heterogeneity. Dynamic estimates show a 19-23% reduction after 10 years, driven mainly by resource substitution rather than energy efficiency or short-term responses. Results are robust to renewable energy policies, highlighting carbon pricing's role in steering medium-term expectations and complementing the climate policy mix.

日本のGX文脈において
日本では2023年度から有報でのサステナビリティ情報開示が始まり、カーボンプライシング(GXリーグ、排出量取引、炭素税)の導入が進む。本論文は炭素価格の実効性を実証的に示し、日本のGX政策設計や企業の排出削減戦略に示唆を与える。
In the global GX context
Globally, carbon pricing is a cornerstone of climate policy, with the EU ETS, UK ETS, and emerging systems in North America and Asia. This paper provides robust empirical evidence that carbon pricing reduces emissions over a decade, supporting its role in the policy mix and informing debates on carbon border adjustments and international cooperation.

📄 Abstract(原文)
Abstract We estimate the effect of the staggered adoption of carbon pricing policies across the globe between 1990 and 2017 on per capita $$\text{CO}_2$$ emissions from fossil fuel combustion. We use recent econometric techniques robust to treatment effect heterogeneity. Our dynamic treatment effect estimations indicate gradual adjustments after implementation, resulting in a 19 to 23 percent decrease in $$\text{CO}_2$$ emissions after 10 years. These effects were primarily driven by resource substitution rather than improvements in energy efficiency and were not driven by short-term responses to carbon prices. Our results are robust to controlling for the potential effects of renewable energy policies. These results highlight the role of carbon pricing policies in steering medium-term expectations and complementing the climate policy mix.
