What does an Environmental Impact Statement (EIS) assess?

An Environmental Impact Statement (EIS) specifically assesses the impact on the environment of a proposed project. It is a detailed document required by law typically for projects that may significantly affect environmental quality. The EIS evaluates various factors, including the potential effects on land, water, air, plants, animals, and for the wider ecosystem. It also discusses alternatives to the proposed project and ways to mitigate any negative impacts identified.

Conducting an EIS is crucial for ensuring that decision-makers and the public are informed about the significant environmental consequences of proposed federal actions before they are taken. Therefore, the focus of an EIS is primarily on environmental considerations rather than financial costs, legal compliance, or community benefits, which are addressed through other means or analyses.
