Bonn has developed into a hub of international cooperation, in particular in the area of environment and sustainable development. In addition to a number of international organizations and institutions, such as the IUCN Environmental Law Center, the City currently hosts 17 United Nations institutions. Among these institutions are two of the so-called Rio Conventions, the United Nations Framework Convention on Climate Change&nbsp and the United Nations Convention to Combat Desertification. The number of UN agencies in Bonn, most of which are based at the newly established United Nations Campus in the city's former parliamentary quarter on the banks of the Rhine, continues to grow.

Bonn is the seat of some of Germany's largest corporate players, chiefly in the areas of telecommunications (telephones) and logistics. Simultaneously, Bonn is establishing itself as an important national and international centre of meetings, conventions and conferences, many of which are directly related to the work of the United Nations. A new conference centre capable of hosting thousands of participants is currently under construction in the immediate vicinity of the UN Campus. At present, the private sector plays a major role in Bonn's economy. With 5 stock listed companies, Bonn has the 4th highest market capitalisation amongst German towns. With headquarters of DHL, T-Mobile and other renowned companies, managers have replaced the public sector. -Wikipedia.
