This working paper aims to provide a rough over-view of existing rules and guidelines on the coopera-tion between the UN and the private sector – at least as they are publicly available. It will describe com-mon features and discuss advances and shortcomings of the most prominent and debated rules and guide-lines. Finally, it will present proposals for improve-ment of the existing rules and steps towards a new regulatory and institutional framework for interac-tion between the UN and the private sector.
