This study investigates the interaction between the green economy, financial technologies (FinTech), and governance in promoting environmental sustainability in the United States from 1990 to 2024. Using Descriptive Statistics, Co-integration analysis, Error Correction Models, and Quantile Vector Autoregression (QVAR), complemented by heatmap visualizations, we examine both long-term relationships and short-term dynamics. Environmental sustainability is assessed through the Environmental Performance Index and greenhouse gas emissions. Results show that renewable energy, forest area, and green-adjusted GDP significantly reduce emissions, while FinTech tools such as digital payments and peer-to-peer lending enhance green financing and resource allocation. However, digital currencies exhibit mixed effects due to their energy intensity. Governance quality emerges as a stabilizing factor, ensuring coherence and resilience. Policy recommendations include strengthening institutions, incentivizing green investments, and regulating energy-intensive innovations.
