The Geneva Environment Network (GEN) is a cooperative partnership of over 50 environment and sustainable development organizations based in the International Environment House and elsewhere in the Geneva area, including United Nations offices and programmes, local authorities and non-governmental organizations. Set up in 1999, with the support of the Swiss Federal Office for the Environment, the GEN secretariat, led by UNEP, actively promotes increased cooperation and networking between its members.
The GEN secretariat organizes and hosts meetings on the environment and sustainable development, such as GEN Roundtables and international workshops, promoting the dissemination of information and public awareness of environmental issues, maintaining a resource centre and cybercafé and providing conference services to the Environment House, and publishing the GEN News and the Geneva Green Guide.
Besides Nairobi, where UNEP has its headquarters, Geneva plays a major role in international environmental governance. The Regional Office for Europe of UNEP as well as numerous organizations and secretariats active in the field of environment and sustainable development in the Geneva area have their headquarters in the International Environment House or in the Geneva area.
