What does an environmental impact statement provide?

An environmental impact statement (EIS) primarily serves to assess the potential effects of a proposed project or legislative proposal on the environment. It is a detailed document that outlines the anticipated environmental consequences, alternative actions, and any potential mitigation measures. In this context, the correct choice indicates that an EIS describes legislative proposals, as it often encompasses thorough analyses of how these proposals may affect various environmental factors, such as air and water quality, wildlife habitat, and cultural resources.

Additionally, an EIS aims to provide a transparent review process that enables public participation and helps decision-makers evaluate the implications of their actions. This is crucial for ensuring that environmental considerations are integrated into the planning and decision-making processes.
