Natural resources, green innovation, fintech, and sustainability: A fresh insight from BRICS

Since the industrial revolution, the financial sector has become a significant claimant toward the growth of human society. However, supporting the adverse environmental projects in financial terms has raised several queries about creating a direct linkage between financial market products and the environment.This research examines the nexus between sustainability, green innovations, financial technologies (FinTech), financial development, and natural resources for BRICS economies during 2000–2019. Using the Method of Moments Quantile Regression (MMQR), the results show that FinTech and natural resources adversely impact environmental sustainability across all three ranges of quantiles (0.10th-0.30th, 0.40th-0.60, and 0.70th-0.90th).Conversely, green innovations and financial development promote environmental sustainability across lower to higher-order quantiles (0.10th-0.90th), while economic growth contributes to higher emissions at major quantiles. Similar findings are endorsed using alternative estimators and suggest practical policy implications.
