Green Light-Year (GLY), known as a Chinese native NGO dedicated to Education for Sustainable Development (ESD), is a private non-enterprise public welfare organization officially registered in Shanghai Minhang District Civil Affairs Bureau in March 2016. In the past six years since its inception, GLY has been exploring the promotion and practicing of ESD concepts at three levels: cognition, social emotion and behavior change. We target Chinese teenagers and youth, and engage them to better understand and implement the Sustainable Development Goals by promoting green lifestyles and sustainable consumption. Within these 17 criteria, we focus on cultivating eight core qualities for young people to meet challenges in the 21st century. Our mission is to make the public enjoy practicing SDGs and to become China’s leading ESD organization.
