This study investigates the consequences of financial development on environmental quality in Malaysia by using monetary access, profundity, and effectiveness as support components from 1990 to 2019. The level of affiliation between the components explored by using appropriate autoregressive lag technique. The variables appeared to have a long-term relationship during the investigation. Monetary events, population expansion, financial development, and energy consumption contribute to environmental degradation in the short and long-run. In contrast, squared fiscal growth boosts green value in the short and long term. As a result, Malaysia hosts the Ecological Carbon Kuznets Bend (ECKC) with a negative and measurable blunder revision phrase that supports the existence of a level connection between these variables. That is, any prior year’s 21.8% imbalance is rectified within a year. Monetary events, financial development, squared monetary development, energy use, and population all impact carbon dioxide flows.
