What does the term environmental baseline refer to in environmental impact assessment?

• A. The existing environmental conditions against which project impacts are measured.
• B. A predicted future state after project implementation.
• C. A list of potential project impacts to be mitigated.
• D. A legal framework governing environmental permits.

Answer: (A)

In environmental impact assessment, the environmental baseline is the current state of the environment before the project starts. It includes existing conditions—physical, biological, social, and economic—at and around the project site, based on field surveys, monitoring data, historical records, and seasonal studies. This baseline serves as the reference point to measure future changes caused by the project, helping determine what would change and how significant those changes might be. It supports assessing impact significance, planning mitigations, and guiding monitoring. It’s not the predicted future state after implementation, not a list of potential impacts, and not a legal framework for permits.
