An Environmental Impact Statement (EIS) is a document that outlines the potential environmental consequences of a proposed action or project. In the context of psychology, the EIS might be used to assess the potential impact that a proposed development or project could have on the mental and emotional well-being of the surrounding community.

For example, a proposed highway expansion project might have an EIS that assesses the potential impact on the local community's stress levels, quality of life, and overall well-being. This information could be used by decision-makers to determine if the benefits of the project outweigh any potential negative impacts on the community's mental health.

Another example could be a proposed housing development near a nature reserve. The EIS might examine the impact that the construction and new residents could have on the local wildlife and its habitat, as well as the potential impact on the mental and emotional well-being of residents who may feel a strong connection to the natural environment.
