Technology innovations and financial development are the tools to achieve sustainable development goals (SDGs) in the carbon neutrality process; however, such nexus has lacked evidence, particularly in top-polluting economies countries. The current study examines the effectiveness of technological innovation and financial institutions on renewable energy consumption and green growth in top-polluting economies by using the cross-sectional Autoregressive Distributive Lag (CS-ARDL) method over the period from 1991 to 2019. The findings show that in the long-run, technological progress and financial institutions are major drivers of renewable energy consumption of top-polluting economies. Moreover, the study shows that technological progress, financial institutions, education, and public spending foster green growth in top-polluting economies in long-run. Top-polluting economies need to improve energy technology innovation and financial institutions for achieving green growth and carbon neutrality targets.
