Abstract: This study empirically examines the asymmetric relationship between public-private partnerships investment in the energy (PPPIE) sector and CO2 emissions for selected Asia economies from 1990 to 2019. For estimation, we used the nonlinear autoregressive distributed lag modelling (NARDL) econometric approach. The findings reveal that a positive change in PPPIE hinders environmental quality by increasing CO2 emissions in Indonesia and Russia in long run. On the contrary, a positive change in PPPIE has a negative influence on CO2 emissions in China and Turkey in long run. The negative shock of PPPIE mitigates the CO2 emissions in long-run in Russia, Indonesia, and Turkey. However, a positive change in PPPIE improves environmental quality by decreasing CO2 emissions in India, Indonesia, and Turkey in the short run. Although a negative change in PPPIE has negative effects on CO2 emissions in only Indonesia, while it has positive effects in India, Russia, and Turkey in the short run. Therefore, the government should encourage public-private partnerships investment in the renewable energy sector in the selected Asian economies by encouraging environmental quality.
