A bank is a financial institution licensed to accept deposits and make loans. Two of the most general types of banks are commercial/ retail and investment banks. Depending on the type, a bank can also provide numerous monetary offerings ranging from imparting safe deposit packing containers and currency trading to retirement and capital management. Above all, crucial banks are responsible for foreign money stability. They manage inflation, dictate economic rules, and oversee money demand and supply inside the market. Green banking is eco-friendly financing. Banks' concern about environmental well-being while financing to businesses is considered as green banking. To get a sustainable positive impact from business, green banking is essential. Businesses are the driver of the economy, and sustainable business can influence the sustainability of the economy; therefore, a successful green business establishment is crucial. Central banks' role is imperative in introducing and implementing green banking.
