Plastic shopping bags have been used in everyday life. In fact, plastic bags production from polyethylene will cause greenhouse gas emission when broken down into small pieces, and hence they contribute to anthropogenic climate change sources. The aim of this study is to examine the effects of environmental knowledge, perceived value and price, product appearance, attitude, subjective norm, perceived behavioral control and intention to purchase reusable shopping bags. The purposive sampling method was used in choosing respondents and the criteria were the respondents who already knew the reusable bag product and had the intention to buy it. Overall, 110 respondents were considered fit to meet the predefined criteria and fill out the questionnaire completely. The instrument testing and also hypothesis testing were tested by Structural Equation Model-Partial Least Square (SEM-PLS).
