Is sustainability a space where we need to let youngsters drive the agenda? If so, who needs to be involved and how can we help grow these ideas? Robert Brown, organiser of the COINS Grand Challenge, a competition aimed a kickstarting innovative ideas to transform the construction industry, chairs a debate exploring how a sustainable future for construction can be achieved. A panel of committed and passionate youthful entrepreneurs who are also scientists, researchers and marketers, will explore ideas from innovations in materials and processes to disruptive business and behavioural models.
