Muhtasari	The Environmental Concern Scale (ECS) measures the degree to which individuals worry about and feel affected by environmental problems, pollution, and ecological degradation. Originally developed by Weigel and Weigel (1978), the ECS focuses on emotional and affective responses to environmental issues—anxiety, worry, and perceived personal threat from pollution—rather than abstract values or beliefs. The scale is widely used in public opinion research, conservation communication effectiveness studies, and assessing emotional responses to environmental threats like climate change and air pollution.	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.
