Green Banking is a bank-led campaign that seeks to encourage environmentally conscious activities and lower the carbon impact of their daily operations. The banking sector is one of the main drivers of a country's development, but as a result of globalization, there is a condition known as the sequential prostration for the establishment of least international financial regulation standards in order to prevent the effects of banking problems or problems in relation to other countries. Due to globalization, bankers are now required to gain insight into customers’ attitudes. Thus, the purpose of this study is to assess the predictability of attitude components and develop a model for measuring customer attitudes about Green Banking Practices in Surat. ABC theory of attitude along with TAM has been used in the study. The data has been collected from 251 respondents using banking accounts. Findings concluded that all three aspects i.e. affective, behavioral, and cognitive play an important role for the implementation of Green Banking Practices. This research also identifies the association between family income of the respondents and years of usage. Thus, it is advantageous for bankers to take these three elements into account when predicting and measuring their customers' attitudes toward Green Banking Practices.
