Submissions deadline: 17 April 2020, 11:59 PM (GMT+8 Singapore time)The Liveability Challenge is a global platform that hunts for and accelerates the launch of innovative and ground breaking solutions to challenges that cities in the tropics face in the 21st Century. By 2050, 2.5 billion more people will live in cities, demanding more food, products and conveniences than ever before. Keeping global warming to 1.5 degrees Celsius will not happen without a strategy to actively remove carbon dioxide (CO2) from the atmosphere. Although carbon capture, storage and utilisation technologies are nascent, costly and space intensive, it represents a huge trillion-dollar business opportunity. From 14 January to 17 April, The Liveability Challenge wants your proposals in urban food production, circular packaging and decarbonisation to make cities in the tropics sustainable and future-ready.
