All commercial banks must take green financing drives to promote environment-friendly projects in their mainstream investment. Inherently, all commercial banks are encouraged to make a profit, but exploring the relationship between GF and bank performance is necessary. This article categorizes the data regarding different types of green financing such as renewable energy, alternative energy, energy efficiency, liquid waste management, recycling and manufacturing of recycling products, Hybrid Hoffman Kiln (HHK), environment-friendly green structures, green agriculture etc. The study feeds an inclusive overview of the GF situation with a particular emphasis on renewable energy (RE), energy efficiency (EE), liquid waste management (LWM), recycling and manufacturing of recycling goods (RRG), producing environment-friendly bricks (PEFB), and green ecology friendly establishments (GEE) and its impact on bank profitability in Bangladesh. This research collects secondary data from related published articles, Bangladesh Bank annual reports, quarterly reports, sustainability reports, other commercial banks' reports, different proceedings, ADB reports, World Bank reports, and national newspaper reports from 2014 to 2023. MS-Excell-2016, with SPSS software version 25, was applied to conduct the research. According to the results of the study, GF has a significant impact on bank profitability. Regression Model 1 indicates that energy efficiency (EE) and the recycling and manufacturing of recycling goods (RRG) have the most positive impact on bank performance (ROA and ROE). Regression Model 2 found that renewable energy (RE) impacts bank performance. However, the main challenge is creating awareness among the bankers, BB, other regulators, and the community. The possible future essence of this study is to convince bankers and policy planners that GF can be the best solution for surviving in the competitive market, maximizing wealth, and improving bank profitability.
