Purpose. To examine long-run and short-run eff ects of industrial fi nancial development on carbon emissions in Bangladesh. Methodology. The auto-regressive distributed lag model was implemented on the data collected from 1976 to 2020 to exhibit cointegration in regression form. Traditional unit roots as well as the Zivot-Andrews structural break test was conducted for investigating a signifi cant single-break. The auto-regressive distributed lag model (ARDL) model approved long-run cointegration having a structural break in this study. Findings. The results conclude that energy consumption triggers carbon emissions with a signifi cant eff ect on short and longrun models but fi nancial development has no signifi cant eff ect on environmental degradation. A considerable U-shape Environmental Kuznets Curve hypothesis is observed at the nexus of carbon emissions and economic growth. Originality. The current study proposed to contribute to the existing literature by assessing the eff ects of fi nancial development, economic growth, and energy consumption on environmental degradation in Bangladesh using modern econometric methodologies. Practical value. The results obtained will be useful to scientists, economists and practitioners dealing with economic and environmental development of diff erent industries. Keywords: fi nancial development, industry, energy consumption, ARDL, economic growth, environmental degradation
