Figure 4 shows the world’s top five contributors to the three IGOs’ 2018 budgets. As the contribution of each member state is determined by factors relating to its relative wealth and economic capacities (GNI, share in world trade, size of population), a direct consequence is that the funding of the IGOs’ budgets tends to be sourced from only a few member states. The US is the biggest contributor in all three cases. As regards the UN and the WTO, China and Japan are also amongst the top five contributors. From among the EU Member States, Germany and France are the biggest contributors to all three organisations. When taken as a whole, EU Member States’ contributions constitute 30.4 % of contributions to the UN, 65.3 % of contributions to NATO and 42 % contributions to the WTO. This places the EU Member States as a whole as the top contributor to all three IGOs (even without including the contribution from the EU budget).
