It has been widely documented in the literature that financial development drives up the impact of CO2 emissions through increases in real economic activities and the consumption of polluting fossil fuel energy. However, when dealing with stock market development, such upward effects on economic growth, energy efficiency, and carbon emissions seems to give away to a positive impact especially in emerging markets. This paper contributes to this debate by exploring both the symmetric and asymmetric responses of CO2 emission to changes in stock market development indicators. Using both the panel linear and nonlinear ARDL, our results demonstrate the asymmetric effects of stock market development indicator son carbon emissions in the context of emerging markets. In particular, the long-run elasticities results suggest that positive and negative shocks on stock market indicator decreases environmental quality by increasing carbon emissions. Based on these empirical findings, this study offers some crucial policy implications. Especially, policy makers should implement strong environmental policies in emerging markets economies to reduce carbon emissions of industrial companies without significantly affecting the development of financial markets.
