Within this work, the authors wanted to approach the different processes necessary for the adaptation of public administration to the requirements of sustainable development, adaptation which accompanies today, increasingly stronger, the collective project called the European model of public administration. The research aims to perform an interdisciplinary study from a comparative perspective of the public administration and sustainable development, by thoroughly studying the problematic afferent to the complementary plans which ground the public administration's tradition towards sustainable development. Even though consensus was not reached, with respect to a European model of administration, the researchers are making considerable efforts oriented towards exceeding the fragmentations existing between the different national administrations, by creating a model of sustainable administration which to be subsequently developed. The book is addressing to academics, practitioners and students who wants to develop their knowledge regarding the issue of creating the conditions of a sustainable development model of public administration.
