The motivation of this study is to evaluate the role environmental innovation, energy efficiency, and institutional quality in achieving sustainable improvement G7 economy for period 1980–2020. has implemented several econometrical tools gauging their empirical association, including cross-sectional autoregressive distributed lag (ARDL) directional causality with Dumitrescu-Hurlin. Study findings cross-sectionally dependency test revealed that variables are sharing common dynamics, while panel stationary documented all were after first difference. Furthermore, counteraction established a long-run association among research variables. coefficients CS-ARDL renewable integration innovation expedite scope sustainability long run. assists augmenting process ecological balance, is, efficient presence inductees affecting policies implementation. Directional feedback hypothesis between sustainability, sustainability. Moreover, unidirectional was By considering findings, advocated considerable time efforts have invest formulating encourage clean ensuring promoting innovation.
