Tóm tắt	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.	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.
