The 1st part of the research study was based on quantitative method to test the developed hypothesis and validity of the instruments. A simple random sampling technique is used to distribute questionnaire amongst selected sample size. Principle component analysis were used to test the unifactoriality of the constructs. The results of all the tests showed that all items of each factor are correlated with each other, moreover it also provides enough confirmation of the construct validity. Structural Equation Modeling (SEM) Technique was used to check the relational hypothesis. The second part of the research study was based on qualitative technique which helped in identifying practicing in business sector and environmental protection agency (EPA). Indepth interviews were conducted from the owners and managers of corporate sector and EPA officials selected through common purposive sampling technique.

The researcher identified major factors affecting green purchase intention. With the help of literature, ignored concept of green marketing is discussed in context of Pakistan. Orientation of experts are also discussed in qualitative part of the study. Finally most important and least important factors are identified through hypothesis testing to fill the gap.
