SMAD is an online platform that aims to promote sustainable lifestyles in Hong Kong and mainland China by sharing ideas and examples of sustainable daily activities, actions, and homemade goods. It was created by the School of Design at Polytechnic University of Hong Kong, along with environmental non-profits, to address issues like pollution and waste in cities by stimulating alternative approaches to consumption through design. The platform gathers and spreads cases of sustainable living to encourage social change around green lifestyles using open sharing on social media.
