Borders are becoming increasingly porous, with growing flows of goods, services, people and capital. Governments, more than ever, need to co-ordinate their efforts to develop global standards to address climate change, as well as crises related to finance, health, environment and migration; secure peace; and ensure sustainable economic prosperity and social inclusion. International organisations play a key role in fostering multilateral action and addressing the fragmentation that may undermine effective domestic action. To shed greater light on international standard setting, this unique report collects, compares and assesses the practices of 50 international organisations on their governance arrangements, operational modalities, use of quality management disciplines and co-operation efforts. It analyses different types of organisations – inter-governmental, supra-national, trans-governmental and private – and identifies avenues for making their action more effective, inclusive and relevant.
