What is NEPA?

The National Environmental Policy Act is our basic national charter for protection of the environment. It is foremost a procedural law that helps ensure that federal decision makers take a hard look at the potential effects of a proposed action and allow the public and other stakeholders to comment on the federal agency’s effects analysis and consideration of reasonable alternatives. The NEPA analysis helps these decision makers understand the environmental consequences of the alternatives in comparative form before making a decision. This “hard look” is informed by the public and other stakeholders, starting with a project or study’s scoping phase.
