Throughout the past few decades, the idea of "Green Banking" has gained popularity among both the general public and the financial and banking industries. This essay aims to illustrate the current state of green banking practice, its development, and many green measures undertaken by Bangladeshi banks to maintain environmental sustainability. The study finds that Bangladeshi banks are doing well in practicing sustainable baking with maintenance of the specific guidelines of Bangladesh Bank through content analysis of the annual reports of Bangladesh Bank (the Central Bank of Bangladesh), annual review report of green banking activities, and annual review report of Direct and Indirect Investment to Green Finance and Climate Risk Fund (CRF). Even though Bangladesh Bank launched the green banking efforts in 2011, it only took a short while for them to be successful.
