Cleaner (sustainable) production is addressed in various legal documents including legislations, policy plans and government incentives in Turkey. However if the factors such as population, level of development, industrial activities and regional policy targets of the country are taken into consideration, the level and extent of cleaner (sustainable) production activities are not at the desired level. So as to overcome this deficiency, the Ministry of Environment and Forestry supported the project "Determination of the Framework Conditions and Research-Development Needs for the Dissemination of Cleaner (Sustainable) Production Applications in Turkey" which was carried out in 2009 by Technology Development Foundation of Turkey (TTGV) and Prof. Dr. Göksel N. Demirer, as the consultant. This paper summarizes one of the outcomes of this project, namely "national capacity assessment on cleaner (sustainable) production". In this study, an assessment of cleaner (sustainable) production oriented activities/capacities of the related institutions/organizations in Turkey is presented. The objective is to determine the background for future activities as well as informing related stakeholders about the national capacity on the subject. This assessment is based on questionnaires carried out among related institutions/organizations and a workshop conducted.
