Chang, Ya-Ju ; Lehmann, Annekatrin ; Winter, Lisa ; Finkbeiner, Matthias (2018-07-02)

The needs of children and their vulnerability to diseases, violence and poverty are different from those of adults. The Sustainable Child Development Index (SCDI) was thus developed in previous work to evaluate the status of sustainable development for countries with a focus on children and triple-bottom-line thinking. This study proposes application options to put the SCDI into practice. The S...
