This 13-item scale evaluates four key domains of pro-environmental behavior: 1) conservation lifestyle behaviors (household choices made by people that broadly influence environmental sustainability, like recycling or water conservation); 2) land stewardship behaviors (direct engagement with the environment, like tree planting or community science); 3) social environmentalism (actions that deal with social relationships, like participating with an environmental group or telling friends about environmental issues) and 4) environmental citizenship (actions related to environmental policy, like voting to support conservation efforts or donating money to conservation organizations).
