First, this article is aimed to identify factors that can influence sustainable consumption, specifically in the green purchase of environmentally friendly products. In order to reach that goal, a literature review was carried out through Scopus. As a result, social influence, environmental attitudes, perceived barriers and green purchase intentions were selected as factors. Second, this research validated a scale to measure green purchase intentions, taking as a reference other scales of literature. The methods included strategies such as expert judgment, cognitive methods, pilot test and reliability coefficients for different appliance categories. The results show that the scale is reliable and measures the proposed constructs.
