Since the year 2000, Expos have taken on a significant role of raising awareness on the importance of sustainable development and addressing the crucial challenges of our time. Expo 2000 Hannover promoted sustainable development and aligned itself explicitly with Agenda 21. Expo 2005 Aichi aimed at demonstrating that there was a clear competitive advantage in designing technology in harmony with nature. Expo 2010 Shanghai was another milestone, as it showcased solutions for sustainable urban development, in a world where half of the population lives in cities.
By providing a unique space for discussion and cooperation, Expos aim at being efficient instruments of progress in all areas linked to sustainable and human development such as the environment, energy, health or education.
