Environmental Impact Assessment (EIA)
An environmental impact assessment (EIA) is an assessment of the possible positive or negative impact that a proposed project may have on the environment, together consisting of the natural, social and economic aspects.
Strategic Environmental Assessment (SEA) is a system of incorporating environmental considerations into policies, plans and programmes.
The purpose of the assessment is to ensure that decision makers consider the ensuing environmental impacts when deciding whether to proceed with a plan or project.
In Estonia both EIA and SEA have to be conducted according to Environmental Impact Assessment and Environmental Management System Act.
