Venue 地點: Conducted via Online Platform
Speaker(s) 講師: Prof. Roland Geyer & Dr. Christelle Not
Summary 內容: Online Book Talk & Sharing
A new publication by one of the world's top researchers
in Industrial Ecology and Pollution Prevention, Prof. Roland Geyer

In this talk, we will first explore why the health of the planet continues to decline, despite the sustained environmental efforts and activities of governments, companies, and each of us as individuals. It appears that the major Earth Summit in Rio de Janeiro in 1992 popularised some ideas about environmental sustainability that have taken us in the wrong direction and these urgently need to be discarded.

Prof. Roland Geyer will then introduce a set of principles that is designed to help humanity off its unsustainable trajectory. These principles are equally relevant for product design and production as they are for consumption. Dr. Christelle Not will also join the discussion and share her insights on this topic.
