The purpose of this study is to investigate the causal relationship among energy consumption, carbon emission, financial development, and tourism using a sample of 12 post-communist countries in the period between 1995 and 2014. The results of Pedroni and Kao tests show the cointegration among observed variables. The Granger non-causality test demonstrates that there is bi-directional causality in financial development–tourism and energy–emission nexuses. The one-way causality is identified in cases of tourism–energy, tourism–CO2, finance–energy, and finance–CO2.
