本研究は、1990年から2020年までのG20主要16カ国のデータを用いて、環境政策の厳格性（EPS）が炭素排出強度と再生可能エネルギー導入に与える影響を分析。市場ベースの排出量取引や再生可能エネルギー支援策が最も効果的であり、新興国でより大きな効果が見られる。政策設計への示唆を提供。
English
This study analyzes the effect of environmental policy stringency on carbon intensity and renewable energy adoption across 16 G20 countries from 1990 to 2020. Market-based instruments like emissions trading and renewable support schemes prove most effective, especially in emerging economies. The findings offer actionable insights for designing targeted climate policies.

日本のGX文脈において
日本がGX推進において政策の厳格性と効果を検討する際に重要なエビデンスを提供。特に市場ベースの排出量取引と再生可能エネルギー支援策の有効性は、日本のカーボンプライシング議論や再生可能エネルギー政策に直接示唆を与える。
In the global GX context
This paper contributes to global GX policy debates by empirically comparing the effectiveness of different policy instruments across countries and development levels. It highlights the importance of market-based mechanisms and technology support, informing global climate policy design (e.g., EU ETS, US IRA, China ETS).

📄 Abstract（原文）
In pursuit of global climate goals and sustainable development, countries have adopted a wide range of environmental policy instruments. This study examines the relationship between environmental policy stringency (EPS) and environmental outcomes, measured by carbon intensity (CI) and renewable energy intensity (REI), in 16 G20 countries from 1990 to 2020. The empirical findings reveal that more stringent environmental policy is a significant predictor of reduced CI and increased REI, although effects vary by policy type, time horizon, and country group. A novel sub-index-level analysis reveals that market-based incentive instruments, particularly trading schemes on CO2 emissions and renewable energy, as well as technology support instruments, particularly wind and solar initiatives, exhibit the strongest and most robust effects. Emerging economies generally display greater responsiveness to policy interventions than advanced economies. By identifying which specific policy instruments are most effective across different development contexts, this study provides actionable insights for designing targeted climate policies that support both energy transition and sustainable development pathways.
