Sustainability “presents a challenge of learning how to live differently, and education is key to this.  But the issue is not just one of putting ESD into the curriculum and teaching materials, important though this is. It is also about cultivating capacities of critical understanding, careful analysis, respect for others and forward-thinking capacities, which enable people to reflect upon and change their behaviour, values and life-styles.”  

-Koichiro Matsuura, Former Director General of UNESCO
