Today, the use of mobile phones and the internet is an inseparable part of our daily lives. They play a significant role in every walk of day-to-day life, with banking not being an exception to this. Various mobile apps and websites have been developed to provide cost-effective and convenient facilities to customers. In the beginning, it was very difficult for a common man to adjust to this new system as cash transactions were a common and popular mode of making payments. However, the long queues and limited working hours of the banking system meant that a lot of time and energy was wasted on every transaction which led to fewer transactions per day. Further, the amount of paperwork involved meant that a lot of paper was used once and then discarded (Sesame, 2018). This was not environmentally sustainable. In the absence of Mobile Banking and Net Banking, the number of visits of the customers to Banks was significantly larger in number and if customers were using vehicles for these visits, it used to result in air and noise pollution, which was not environmentally sustainable.Mobile banking has various benefits such as the convenience of checking account balance, and transactions, transferring funds, making and receiving payments remotely at any time, having fraud checking mechanisms, etc, faster than it would take them to do the same activity in person at the bank (Strohm, 2021).Demonetisation and the COVID-19 pandemic proved that mobile banking is an essential service rather than a novelty (Wisniewski, 2022). This is due to the fact that it is both cashless and contactless.This paper tries to focus on the customer’s awareness in the city of Dombivli of mobile banking in the city of Dombivli, with a special emphasis on its environmentally friendly aspect
