The Vienna Energy Forum (VEF) is a biennial global, multi-stakeholder forum with the objective of exploring developmental challenges within the realm of sustainable energy. The Forum introduces a platform for policy- and decision-makers from all sectors of society to conceive practical solutions to sustainability issues.

Since its founding in 2008 by a joint initiative of the Austrian Government, the International Institute for Applied Systems Analysis and the United Nations Industrial Development Organization, the VEF has assembled thinkers and practitioners from all over the world to discuss practical solutions to sustainable development challenges and pave the way for tangible partnerships on the ground.
