Six groundbreaking solutions to help cities accelerate decarbonisation and address their resource challenges have been shortlisted for the grand finale of this year’s The Liveability Challenge—a global search for innovative solutions to urban challenges of cities in the tropics.

Back for its fourth year, the initiative is presented by Temasek Foundation and organised by Eco-Business, and provides a platform for connecting investors and entrepreneurs in the sustainable development space.

Under the themes of decarbonisation and re-imagining resources, this year’s shortlisted solutions include technologies that recycle lithium batteries, large-scale removal of carbon dioxide through seawater, and a high barrier coating film that makes packaging recyclable.

Following a four-month global search, the finalists beat out more than 400 applications from over 60 countries. Most of the finalists are from Singapore, with other contenders from the United States and the United Kingdom.
