#IFWE Challenge is a social conversation contest to stimulate the most innovative world-changing dreams. Participation is very simple: think of how you’d like to change the world and write it down in the form of a short sentence starting with the words “#IFWE”.
By submitting your IFWE Dream, you will automatically enter for a chance to win prizes valued up to $12,000! Our jury of experts and dreamers will carefully select the top three submissions based on the criteria of sustainability, originality and feasibility.
