Environmental Site Assessment Study (ESA) is designed to identify and evaluate, to the extent feasible, any environmental concerns in connection with a subject property. This assessment includes a site reconnaissance as well as consultations and interviews with representatives of the public, property management, and regulatory agencies.

Environmental Post Impact Assessment is a post-project-analysis carried out for confirmatory assessment of the environmental impact of established projects, the efficiency of preventive measures, as well as proposing remedial plans or measures, to achieve the coordination between project operation and environment.

Strategic Environmental Assessment (SEA) is a systematic and comprehensive process of identifying and evaluating the environmental consequences of proposed policies, plans or programmes to ensure that they are fully included and appropriately addressed at the earliest possible stage of decision-making on a par with economic and social considerations.

It is applied to sectoral and national policies as well as geographical and regional development schemes. It streamlines and focuses the incorporation of environmental concerns (including biodiversity) into the decision-making process, often making project-level EIA a more effective process.
