Natural resource abundance, growth-oriented strategies and low environmental concern of post-Soviet states may exacerbate the consequences of climate change significantly. This study considers the relationship between CO2 emissions, economic development, foreign investment inflows, trade and energy use in 20 post-Soviet states between 1995 and 2017. A panel cointegration test reveals the long-term cointegrating relationship between the variables. Long-term elasticities are reported using Dynamic Ordinary Least Squares and Fully Modified Ordinary Least Squares regressions, which yield quite similar results: GDP per capita, foreign direct investment (FDI) inflows, trade and energy use positively related to CO2 emissions per capita in the long term. A panel causality test, however, identifies unidirectional causality running from CO2 emissions to energy use at p<0.01.
