A compendium of targets and indicators has been compiled by the UN technical support team to inform the deiliberations of the Open Working Group on Sustainable Development Goals. The compilation consists of existing goals and targets which relate to the 19 Focus Areas being considered by the OWG on SDGs.
The compendium will help ensure that the OWG creates an SDGs proposal that is consistent with international law and builds on commitments already made.
The list is not neccessairly exhaustive or complete. As more information becomes available, the compilation will be updated.
In addition, the Co-Chairs of the Open Working Group have put together a helpful presentation entitled "A definitional note on goals and targets", which is available here.
