Do-nothing comparison
Environmental Impact Assessment Handbook, Guidance for competent authorities, consultation bodies, and others involved in the Environmental Impact Assessment process in Scotland, published by Historic Environment Scotland and Scottish Natural Heritage in 2018, states that the do-nothing comparison, or in some cases, such as road improvements, the do-minimum comparison: ‘is a projection of the existing data to provide a baseline for comparison to show what changes, if any, would take place if the project did not go ahead, or what the conditions would be on the road, railways, etc., if the project was not undertaken.’
