    Attendee testimonials


    "It's a very unique platform which unites impact-driven people from around the world. I met people from higher education, from business, from different industries all willing to make an impact."

    – Nadine Zidani, Founder, Sustainable Change-Makers Academy


    "No one person, no one organisation, no one country can do this on their own, and I think that events like this help to cultivate that mindset and that collaborative approach."

    – Chester Chua, Head of Government Affairs and Public Policy, Google Cloud


    "What's really valuable about this congress is that it's bringing together people and thinkers and policy makers and actors from different sectors."
