Will reducing the service trade barrier improve environmental performance in OECD countries?

The rapid expansion of the global economy poses a serious threat to the environment due to the ever-increasing demand for fossil fuels. While trade can contribute to greenhouse gas emissions and other pollutants in the absence of appropriate environmental regulations, it can also be a crucial tool in addressing the climate crisis and other environmental challenges. This study empirically investigates the relationship between several factors and environmental performance in OECD countries to support the theoretical argument. These factors include the Service Trade Restrictiveness Index, renewable energy consumption, technological innovation, GDP, and international trade. The aim is to understand how these variables impact CO2 emissions, providing policymakers with insights to develop more effective climate change mitigation strategies. The analysis utilizes panel data from 35 OECD countries covering the period from 2014 to 2022. The Benchmark Ordinary Least Squares and Two-Stage Least Squares methods are employed to estimate the nature of the relationships between the variables of interest. The findings reveal that trade and service restrictions, renewable energy, and technological innovation contribute to reducing carbon emissions. However, GDP growth and trade are positively correlated with CO2 emissions, indicating that economic growth and increased trade are associated with higher carbon emissions. These results underscore the importance of promoting environmentally friendly technological innovation and sustainable development while cautioning policymakers to carefully consider the potential benefits of service trade restrictions. The research also highlights the challenges of achieving a balance between economic growth and environmental protection, urging the adoption of sustainable practices to mitigate the adverse environmental impacts of GDP growth. Policymakers, environmental organizations, and researchers can use this study's findings to inform effective climate change mitigation efforts.
