The goal of this study is to investigate the potential effects of international trade on per-capita CO2 emissions among trade partners. To achieve this purpose, the Group of Seven (G7) countries and each of their developing trade-partner countries with the highest trade volume have been selected as the sample. The stochastic convergence methodology has been employed using Augmented Dickey Fuller (ADF), Phillips-Perron (PP), and Enders-Lee Fourier unit root tests in order to test for convergence or divergence. Various results have been obtained from the unit root tests. These results suggest international trade to have no general or common effects on per capita CO2 emissions.
