The relationship between green banking practices and organisational performance is examined in this study using the three categories of organisational performance—financial, environmental, and operational. Using information gathered from private and public sector banks of Haryana, a conceptual model based on the resource-based theory is empirically tested. Employees from various banking organisations represent their views with the help of google form. Hypothesis and structural model have been set up and also data has been analysed using “partial least squares” (PLS) SEM approach. The analysis of the survey data is done by structural equation modelling. The findings shows that GBP (green banking practices) and operational, financial, and environmental performance are positively related to each other. Additionally, it was discovered that environmental performance partially and strongly mediated the impact of green banking practices on financial performance as well as the relationship between green banking practices and operational performance. The paper’s conclusions offer directions to the bankers (assistant manager, policy makers) which motivators have been considering while adopting green practices in banks and what will be the the result after such adoption.
