This study focuses on the recent past of the concept of sustainability, and one of its most important components, environmental sustainability which included our lives in the second half of the 20th century. Sustainable development was recognized internationally for the first time in 1987 as a general expression of the search for a balance among economy, society, and nature in terms of the resources with the principle of intergenerational equality. After this date, both Turkey and many other nations of the world provided various agreements and commitments on environmental sustainability related to their concerns for the common future. In this context, the aim of the study is to review the progress and the results of these various approaches. Turkey's history of environmental sustainability at both international and national levels has been examined in four periods. Periods are examined according to dominant sentiment, national period-specific characteristics, international treaties, legislative regulations, urban planning characteristics, and planning paradigm titles. It is found that both global and local goals have not been achieved yet, by this study which scrutinizes the recent history with almost 50 years to the present. The process that started with real problems and sensitivity in the practice continued with fashion and discursive expressions in times. It is understood that the sustainable urban environment, one of the main goals of urban planning has also turned into an ideal. Therefore, the steps that will be taken by Turkey within the environmental crisis period which have been experienced since 2010 are also supposed to determine the future of urban planning.
