As nations accelerate their digital and financial transformations in pursuit of sustainability, a critical question emerges: do technological and financial advancements truly deliver environmental gains, or do they mask deeper ecological costs? This study explores the dual impact of artificial intelligence (AI) innovation and financial development (FD) on environmental sustainability in the world’s 15 most innovation-driven economies over the period 2000–2023. Using the Method of Moments Quantile Regression (MMQR), the analysis captures heterogeneous effects across different levels of carbon emissions. The findings reveal a paradox: while AI innovation is often positioned as an enabler of green growth, it is associated with increased CO2 emissions in energy-intensive economies, particularly at higher quantiles. In contrast, financial development contributes positively to environmental quality, but its benefits taper off as emission levels rise. Energy consumption plays a critical role in both relationships, amplifying or dampening environmental outcomes depending on a country’s emission profile. These results challenge the optimistic narrative around digital and financial solutions, urging policymakers to reconsider how innovation is governed and aligned with environmental objectives. The study offers practical insights for stakeholders seeking to bridge the gap between green promises and real-world ecological outcomes.
