Abstract: SEA can be defined as a systematic process, evaluating the environmental, economic and social results of any suggested policy, plan or programme. Therefore; it has more advantages than project-level environmental assessment. Also, it provides a more holistic approach towards sustainable development. SEA applications have mostly been seen in developed countries; however, they are also important for developing and underdeveloped countries in order to keep with the principles of their sustainable development. Till now, the development process for these countries has worked with an approach aiming more income in the short term. This approach has often caused the environmental factors to be ignored. For this reason, SEA is a part of the foreign aid policy of supranational organizations like the United Nations Development Program (UNDP) or the project support by the World Bank today. In developing countries, one of which is Turkey, international relationships, volunteer institutions and public have shown influential impression on the efforts to develop preventive policies such as SEA and EIA against environmental problems in recent years. However, different problems have emerged during the integration of SEA into the legal systems of countries. This integration process is more difficult than expected for some countries. During the adaptation process into the EU laws, some actions about integration of EU-SEA Directive were taken with the support of the Netherlands Government and a draft SEA regulation was prepared in Turkey. Establishment efforts of an institutional base for the effective utilization of SEA are in progress at the Ministry of Environment and Urbanization and at other institutions. This study has focused on the development of SEA in Turkey and the integration of EU Directive on SEA. The draft SEA regulation framework has been compared with the procedure and experience in Germany.
