Revealing the effectiveness of technological innovation shocks on CO2 emissions in BRICS: emerging challenges and implications

The debate on technological innovation shocks and its effect on the environment are of great interest to academicians and environmentalists worldwide. At present, primary focus of this research is to investigate the asymmetric technology shocks and its impact on CO2 emissions for BRICS economies. The linear and non-linear panel ARDL models are applied to compute both short-run and long-run dynamics of technology shocks and CO2 emissions. Asymmetric estimates confer that a positive shock in patents reduces the CO2 emissions by 0.418%, whereas negative shock increases the CO2 emissions by 0.854%. Contrariwise, the trademark positive shock increases the carbon emissions by 0.416% and vice versa. The non-linear analysis provides an opportunity to measure the direction and magnitude of positive and negative shocks in technology on the environmental quality of BRICS economies. Hence, policymakers and environmentalists should devise their strategies by keeping in mind the impacts of positive and negative shocks.

Automated summary

This study examines the impact of technological innovation shocks on the environment, specifically focusing on the asymmetric effects on CO2 emissions in BRICS economies. The findings show that positive shocks from patents reduce emissions, while negative shocks increase emissions. Non-linear analysis allows for measuring the direction and magnitude of these shocks on environmental quality. As such, policymakers and environmentalists should consider the impacts of these shocks when formulating strategies.
