The sustainable remediation emerged as a paradigm shift within contaminated sites management. However, this approach still has difficulties and therefore its application is quite limited. Thus, this paper aims to present and analyze the characteristics and trends of sustainable remediation approach in developed and developing countries, with an emphasis on Brazil case. Firstly, the background to sustainable remediation approach is presented. The discussion is carried out through a contextualization of the main barriers and challenges in sustainable remediation consideration and application in worldwide. The main perspectives and recommendations about the sustainable remediation were contextualized. Finally, approaches of sustainable remediation in developed and developing countries context was presented and analyzed, with emphasis on Brazilian situation. It is concluded that sustainable remediation is of great importance and that many advances have been made; however, the use of the term is still in adaptation process, especially in developing countries. In Brazil, at the same time as it is verified that has the regulatory structure focused on the management of contaminated sites is fairly recent, the sustainability considerations in this context are almost nonexistent.
