Abstract
The D-8 member states have been facing persistent environmental challenges that hinder their sustainable development. This study examines the impact of green innovation (GI), information and communication technology (ICT), and natural resource rents (NRR) on ecological footprint (EFP) in the D-8 economies for the period 1995 to 2024. The cross-sectionally augmented autoregressive distributed lag (CS-ARDL) approach is used for estimation after detecting the existence of cross-sectional dependence and slope heterogeneity. The long-run CS-ARDL estimates indicate that green innovation and ICT reduce the ecological footprint, whereas natural resource rents increase it. The coefficient on RE is statistically significant with negative sign in the long-run but positive in the short-run exhibiting transitional adjustment effect. However, MM-QR estimates, reveal a quantile-specific picture: renewable energy exerts a positive but gradually weakening effect on EFP across the whole conditional distribution, consistent with a rebound effect. The CS-ARDL and MM-QR estimates diverge for RE and NRR. Emirmahmutoglu–Kose (E-K) Causality test shows that RE is the variable most consistently and causally associated. Overall, the findings support heterogeneous, country-specific policy responses over a single identical policy prescription.
