Carbon dioxide emissions are a major cause of global climate change. The public is aware that the world must rapidly reduce its windows to avoid the worst effects of climate change. But how this responsibility is distributed between regions, countries, and individuals has become a recurring element of debate in international debates. This study aimed to compare the different impacts of exporting and importing CO2 emissions in 29 selected countries with the Belt and Road Initiative from 2008 to 2019. We will also look at the impact of innovations on CO2 emissions. Regular testing is done using cross-sectional data, panel data, and integrated testing. Sector results show that exports and imports have a negative effect on CO2 emissions.. EKC is useful in these countries. In addition, population size and energy efficiency increase CO2 emissions. Modern technologies reduce CO2 emissions by increasing energy efficiency. It is important to promote environmental sustainability and the development of professional enterprises in certain countries.
