Tóm tắt	The Carbon Footprint Awareness Scale (CFAS) measures individuals' knowledge, consciousness, and sense of responsibility regarding their carbon emissions—how much people understand the carbon impacts of their consumption, energy use, and travel patterns. Developed by Collins, Gössling, and Hall (2011) for sustainability tourism research and extended to general populations, the CFAS captures awareness of carbon-intensive activities, estimation accuracy of personal emissions, and commitment to carbon reduction. The scale is critical for evaluating climate communication effectiveness, identifying knowledge gaps that block behavior change, and assessing whether carbon labeling, footprint calculators, and climate education successfully shift consciousness of personal climate impact.	The Ecological Footprint Knowledge Scale (EFKS) measures individuals' understanding of the ecological footprint concept—how much land and resources one's consumption requires—and knowledge of personal and global footprint impacts. Developed from the ecological footprint framework (Wackernagel & Rees, 1996), the EFKS assesses both conceptual comprehension (what is an ecological footprint?) and applied knowledge (how to estimate footprint, what factors affect it). The scale is critical for evaluating environmental education effectiveness, understanding why some individuals adopt sustainable consumption despite high footprint knowledge gaps, and identifying knowledge barriers that block behavior change.
