Environment and sustainable development has always been the hot topic around the world and it’s also a major challenge we’re facing. In this context, Professor Wang Guangtao suggested that we should provide platform for talents from different country to think and exchange ideas about major environmental issues, and improve their ability to solve problems so that they can make great contributions to the sustainable development of society. With the support of UNEP and BEFYT, the International Student Conference on Environment and Sustainability has been successfully held in Tongji for three times since 2010. Every year we invited 300 students from nearly 50 countries out of 1500 applicants coming to Tongji University, sharing their ideas and practice focusing on the topics on Sustainable Development, like food, health, ecosystem, green city and green consumption.
