It's financed by the Network of European Foundations, which is a group of western European foundations that work together on various global issues. I myself am a member of the Network of European Foundations. I run a foundation called the Gabriel Foundation for a Swiss philanthropist, Stephan Schmidheiny, who was a co-chair of the Rio Earth Summit and the founder of the World Business Council for Sustainable Development. He's the major financier, through the Network of European Foundations.
