This paper aims to develop a model based on ISO 14001(EMS) clauses to improve environmental performance and enhance business efficiency in Indian context. For this purpose, a questionnaire was prepared considering all the clauses to understand and arrive at better performance. Input and output variables were derived through deep study and reviewed by people involved in implementation. Based on 146 responses, the present research has resulted in a strong relationship between each clause of ISO 14001. The findings of this study confirm that input and output variables have a positive and significant relationship. The reliability and factor analysis is done by adopting SPSS software, and models are prepared for the same industries. In the present study, linear regression coefficients R = .869, .833, and .847, which indicates that there is strong correlation between independent and dependent variables. Multiple linear regressions were performed on five independent variables toward three dependent variables, and results for the regression models were significant, i.e., Sig. = 0.000. The availability of resources (0.624 to 0.906) is found to be more significant for input variables among the other four variables, whereas the input variables, i.e. achievement of objective, has come out as the strongest amongst all output variables. It has been observed that Model 1 has contributed more in the present study, which proposes significant improvement after implementing the model in any sector of ISO 14001-certified industries.
