The National Environmental Policy Act (NEPA), enacted on January 1, 1970, is a pioneering legislation in the United States that established a comprehensive framework for the protection and improvement of the nation’s environment. Aimed at promoting a harmonious relationship between humans and the environment, NEPA was the first major environmental law in the U.S that set forth a national policy promoting the enhancement of the environment. It was signed into law by President Richard Nixon and required federal agencies to evaluate the environmental impacts of their actions.
In a broader context, NEPA requires the consideration of environmental aspects during planning and decision-making processes. It mandates governmental agencies to prepare studies, namely Environmental Assessments or Environmental Impact Statements, to evaluate the potential implications of planned activities on the environment. NEPA also encourages transparency, ensuring that the public can participate in and review the environmental decision-making process, thus, serving as an essential democratic tool to inform, guide, and check government action related to the environment.
