| Samenvatting≠ | The Green Purchase Intention Scale (GPIS) measures consumers' stated willingness and likelihood of purchasing environmentally friendly products, including their intention to pay premium prices for eco-labeled goods and their perceived value of sustainable alternatives. Developed from consumer behavior and willingness-to-pay frameworks (Dodds, Monroe, & Grewal, 1991; expanded by Thøgersen and others), the GPIS bridges environmental attitudes and actual purchasing behavior, a critical gap in sustainability research. The scale is widely used in marketing research, environmental policy evaluation, and studies examining whether environmental concern translates into purchasing decisions. | The Sustainable Consumption Scale (SCS) measures the extent to which individuals adopt sustainable and ethical consumption practices across multiple life domains including food, clothing, household products, transportation, and waste. Developed within ecological economics and consumer behavior frameworks (Sundström, 2014; Vermeir & Verbeke, 2008), the SCS captures integrated sustainable lifestyle rather than isolated green behaviors. The scale is widely used in research on sustainable consumption patterns, consumer segmentation for green marketing, and evaluation of sustainability interventions targeting lifestyle transformation. |
