Does green innovation mitigate consumption-based carbon emissions? The role of nuclear energy consumption and energy productivity in G-7 nations

Abstract

Green innovation, clean energy consumption, and improved energy productivity are crucial for addressing global climate change and combating ecological degradation and are emphasized for their dynamic role in creating a sustainable future. In that sense, this research probed the influences of green innovation, nuclear energy use, and energy productivity on consumption-based carbon emissions in the G-7 economies from 1990 to 2021. Advanced econometric methods were employed, including CS-ARDL for long-run linkage, AMG and CCEMG for robustness, and the DH causality approach. The long-run results specified that green innovation, utilizing nuclear energy resources, and improving energy productivity support decreasing consumption-based carbon emissions. This work recommended implementing the investment in green innovations, expanding nuclear energy consumption, and utilizing energy productivity to lower the existing consumption-based emissions level through policy implementation for G-7 nations.
