Gesellschaft für internationale Zusammenarbeit (GIZ)

Environmental problems do not stop at borders, which is why ifeu has long been involved in international cooperation as a matter of course. For more than 25 years we have been a regular contributor to projects undertaken by the German Society for International Cooperation (GIZ – formerly GTZ). The topics in GIZ are just as diverse as they are at ifeu: air pollution and hazardous waste management in Mexico City, transport concepts in Colombia and China, palm oil production in Thailand, copper mining in Chile, waste management in India, to name just a few. The nature of the projects also corresponds to the ifeu’s usual broad spectrum – professional consultancy service for decision-makers, research and development, and capacity building.
