Five shortlisted proposals were presented at a webinar on Tuesday (May 25) hosted by Sustainability Exchange, an initiative launched in January by non-profit group EB Impact, in partnership with Facebook and supported by the Climate Action SG Alliance. Commenting on one of the proposals – where a team had developed a game called Foodprint – SMU Associate Professor of Science, Technology and Society Winston Chow, who was on the judging panel said, "Gamification is always a great way to help people visualise difficult topics." He commended the shortlisted proposals for the level of research and practicality.
