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 Pro-Environmental Behavior Scale (PEBS) measures the frequency and breadth of environmentally responsible actions that individuals perform in their daily lives, including recycling, energy conservation, water conservation, sustainable transportation, sustainable consumption, and environmental activism. Unlike attitude scales that measure beliefs or concerns, the PEBS captures actual or self-reported behaviors—providing a bridge between environmental intentions and demonstrable actions. The scale is essential for evaluating behavior-change interventions, tracking progress toward sustainability goals, and understanding which demographic and psychographic segments adopt environmentally responsible practices.
