Abstract:

In recent years, there has been an obvious increase in public concern over global warming and its potential effects on climate change. In response, governments attempt to plan international climate change strategies to alleviate global warming. Empirical studies illustrated that carbon dioxide (CO2) emissions are regarded as the main cause of greenhouse warming. Therefore, the examination and analyzing of the stochastic dynamics and persistence of CO2 emissions are vital for policymakers to estimate the impact of carbon emissions to the environment. In this study, it is examined convergence and persistence in per capita CO2 emissions among Africa, Central & South America, Centrally Asia, Centrally Europe, Far East, Middle East, North America, Oceania and Western Europe countries during the 1950-2004 period by applying panel unit root methodology. The IPS (Im, Peseran - Shin) tests illustrated that one cannot reject the null hypothesis of unit roots for per capita CO2 emissions. The results, therefore, illustrate a very strong form of persistence for the CO2 emissions among these country groups
