In the EIA framework, what document characterizes the existing environment before project implementation to serve as a reference for impact comparisons?

• A. Mitigation plan.
• B. Environmental performance report.
• C. Environmental baseline.
• D. Emergency response plan.

Answer: (C)

In the EIA framework, the environmental baseline describes the current state of the environment before any project activity begins. It provides a snapshot of existing conditions across relevant dimensions—air, water, soil, biodiversity, land use, climate, and socio-economic factors—so that future changes caused by the project can be measured and compared against this reference point. The baseline is what you use to assess predicted impacts and to quantify actual changes during and after implementation. A mitigation plan focuses on reducing or preventing negative effects, an emergency response plan outlines actions for handling incidents, and an environmental performance report tracks environmental performance after the project. Because only the environmental baseline identifies the pre-project conditions used for impact comparisons, it is the correct choice.
