How to Write an Environmental Impact Report

An environmental impact report is also known as an environmental impact statement (EIS). The term refers to a document that describes the effects that an action may have on the environment, meaning on the existing state of a particular site prior to the action. They are a requirement of law in certain states. One must be prepared and submit before taking any action that may affect the environment.

• Make the decision to write the environmental impact report. There must be adequate evidence that the proposed action could impact the existing state at a location. The report must include all the potential consequences of the particular action as well as methods by which those consequences may be lessened. The environment includes, but is not limited to, nature. It may also include such things as the culture and the economy in a particular location where the quality of life may be affected by the action.


• Propose steps that may be taken to lessen the consequences of the proposed action.


• Describe the location that may be affected by the action including animals, plant life and historic structures. Potential impacts to air and water quality should also be described.


• Detail existing options other than the proposed action, along with their potential environmental consequences.


• Calculate the financial cost of the consequences of the action, and also of the steps to lessen the consequences. A similar calculation should be done on the alternatives to the proposed action.


• Supply proof that there are available funds to pay for the steps to lessen the consequences of the action. This will usually be done with the use of financial documents.
