Environmental Impact Assessment (EIA)
The basic framework for the Environmental
Impact Assessment (EIA) process is provided by European Directive
83/337/EEC and its amendments in 1997, 2003 and 2009. In 2011, the

The EIA process does not in itself decide if consent should be

of the environmental implications of projects. The Regulations must

Even a small scale project can have significant effects if it is in
a sensitive location.

This helps the decision makers consider the predicted effects of
the proposed project before granting consent for development and
allows all concerned to consider and develop means to avoid, reduce
or by remedying any adverse environmental effects before a final

the environment covers all aspects and stages of a project proposal
