The aim of the COHNECS-IT project is to carry out a systematic review, which is an exercise of evidence synthesis based on published knowledge from researchers and experts in order to inform decision makers. The goal of this exercise is to answer a practical question, by carrying out a knowledge synthesis, understandable of all and robust to possible criticisms. A systematic review is based not only on scientific publications but also on grey literature and follows a standardized and internationally approved protocol. In the environmental field, the international institution giving its seal of approval to systematic reviews is the Collaboration for Environmental Evidence.

Practically, this study will lead to the publication of two scientific publications: the systematic review protocol and the systematic review itself, both of which will be published in an open-access peer-reviewed scientific journal. Practitioner briefs and guidelines for the ordering institutions will be produced, as well as promotions of the results of the project under various forms (posters, conferences, etc.).
