**3. Methodology**

In order to broaden the scope of the research, both primary and secondary sources were utilized. Bibliographical references, as secondary sources, were the basis for the examination of international and Greek practices in the adoption of SEA methods and techniques. Subsequently, an effort was made to gather information relevant to the selection of SEA methods and techniques in Greece from the primary sources. The survey was carried out through the filling out of questionnaires by SEIA practitioners. The final conclusions of the paper comprise and utilize the findings of both the primary and secondary research.
