To allow the ISC3 a quick start to its substantive work, the clients (⁠UBA⁠/⁠BMUB⁠) have commissioned the drafting of three studies. The objective of this study was to create a knowledge base by mapping the most relevant initiatives/approaches in the field of sustainable chemistry. For this purpose, the follow-ing sectors were examined: Green chemistry (n = 8), international organizations (2), (chemical) indus-try approaches (5), approaches from the upstream/downstream value chain (3), approaches at com-pany level (6), approaches in sustainability reporting, sustainability rating and socially responsible in-vestment (4), approaches from further non-governmental/non-profit organisations (NGOs/NPOs) (1), and research approaches (1). Gaps were identified and recommendations for the future work of the ISC3 were derived.
