In this article, I have assessed whether carbon pricing effectively controls international CO₂ emissions. For this purpose, I run a panel data regression analysis by utilizing Per Capita CO₂ emissions as a dependent variable and Carbon Tax initiatives as an independent variable in the presence of five control variables. Unlike other studies, my research sample included not only all the countries for the sample period 2019–2021 but also the effectiveness of all Carbon taxes and ETSs operating worldwide. The outcomes show that carbon tax has a statistically significant and negative impact on CO₂ emanations. The mitigation impact of a carbon tax is powerful and depicts that all 64 Carbon Tax/Pricing initiatives operating internationally are helping the world to reduce national and international CO₂ emissions. These findings are also consistent with the argument raised in this study that once a carbon tax is applied or is under consideration, a reduction in CO₂ emissions follows. This study provides policymakers with significant implications of the country's Carbon Tax initiatives in the best interests of the world's stakeholders.

在本文中，我评估了碳定价是否能有效控制国际CO ₂排放。为此，我在存在五个控制变量的情况下，利用人均 CO _{2排放量作为因变量，将碳税举措作为自变量，进行面板数据回归分析。}与其他研究不同，我的研究样本不仅包括 2019-2021 年样本期间的所有国家，还包括全球范围内所有碳税和碳排放交易体系的有效性。结果表明，碳税对CO ₂排放具有统计显着的负面影响。碳税的缓解影响是强大的，表明国际上实施的所有 64 项碳税/定价举措正在帮助世界减少国家和国际 CO ₂排放。这些发现也与本研究中提出的论点一致，即一旦征收或考虑征收碳税，CO ₂排放量就会减少。这项研究为政策制定者提供了该国碳税举措对世界利益相关者最大利益的重大影响。
