The objective of this report is to map the process undertaken by different regional governments in the implementation of the SDGs. Building on the mapping exercise, the report stresses a set of clear overall policy recommendations and approaches that could be replicated by regional governments. The report is based on a survey carried out with 47 regional governments across the globe, and was jointly developed by nrg4SD and the University of Strathclyde Centre for Environmental Law and Governance. Based on the data collected, it was possible to identify common trends, good practices and shared difficulties, and to draw policy recommendations aimed at further improving the implementation of the SDGs by regional governments. The data collected also provides relevant inputs to the follow-up and review mechanism of the 2018 HLPF.
