本論文は1990～2021年の米国データを用い、環境税、政策厳格性、資源依存、貿易、グローバル化がCO2排出へ与える影響をARDLモデルで分析。長期では環境税が逆説的に排出増加に関連する一方、政策厳格性は有意な削減効果を示す。非対称な政策効果や因果関係も明らかにし、政策の再調整と低炭素技術の普及を提言。
English
This study analyzes U.S. data from 1990-2021 using ARDL modeling to examine how environmental taxes, policy stringency, resource dependence, trade, and globalization affect CO2 emissions. Environmental tax revenue is paradoxically associated with long-run emission increases, while policy stringency significantly reduces emissions. Asymmetric policy effects and Granger causalities are identified, urging recalibration of tax policies and promotion of green globalization.

In the global GX context
This paper provides empirical evidence on carbon pricing and regulatory stringency in the U.S., offering lessons for global carbon pricing design. The finding that environmental tax revenue may increase emissions highlights the need for careful policy calibration. Relevant for ISSB and TCFD discussions on policy risk and transition planning.

📄 Abstract（原文）
Abstract In light of renewed United States of America (USA) commitments to the Paris Agreement, this study dissects the nation’s carbon emission problem by tracking how carbon pricing, regulatory stringency, resource dependence, trade, and global integration interact to shape per capita CO 2 emissions (CPC) from 1990 to 2021. By establishing the intricate dynamics among environmental policies, economic factors, resource dependency, and globalization in shaping the trajectory of carbon emissions, this study modelled the autoregressive distributed lag (ARDL) and the resulted long-run estimates have shown that environmental tax revenue (ETR) is paradoxically associated with increasing the emissions in long-run, hinting at design flaws or lagged adjustment in the USA fiscal instruments. The policy-related predictor, such as environmental policy stringency (EPS), has only been seen as an important player in keeping emissions downward with a significant reduction potential. However, total natural resource rents (TNR), likewise, nudge emissions upward, similar to the globalization’s (GBKOF) impact on the emissions, and trade openness (Trade). Dynamic simulations of ± 10% shocks underline the asymmetry of policy effects: cutting the ETR sparks a sharp increase in emissions, whereas tighter regulation yields great and steadier gains. A highly significant error-correction term (−0.9) signals rapid convergence to equilibrium, and Granger causality tests reveal that the stringent policy has reverse causality with emissions, where the rest of the predictors show forward causality. Only GBKOF has shown significant bidirectional causality. The findings urge USA policymakers to recalibrate environmental tax policies, hard-wire regulatory ambition into federal-state frameworks, and ensure green globalization to diffuse low-carbon technologies to reduce environmental degradation.
