The Liveability Challenge (TLC) is an annual global initiative that seeks innovative, groundbreaking solutions to address urban challenges in the tropics. It crowd-sources the world for the best sustainability solutions and provides both the funding and ecosystem support required to take these ideas from laboratory to market.
Presented by Temasek Foundation and organised by Eco-Business, TLC was established in 2018 and has since grown to become Asia's largest sustainability solutions platform with a global reach and a reputation for helping companies — whose innovations are disrupting industries to create significant positive impact for society and planet — achieve success.
With eight successful editions concluded, TLC has attracted thousands of applications globally, shortlisted and incubated 54 start-ups, and deployed almost S$14 million in funding to help these startups, who have gone on to raise hundreds of millions more.
TLC 2026 launches with a record pledge of S$4 million in catalytic funding and support to accelerate sustainability innovations from lab to market. The challenge is now open for submissions under two themes: Decarbonisation and Cool Earth, and will close on 9 February 2026. Finalists will be showcased at the Grand Finale during Ecosperity Week 2026 in Singapore.

From a record-breaking 1000 entries from more than 100 countries, the 2024 battle to win S$2.5 million in funding saw innovations such as sustainable aviation fuel and cricket-derived protein making the shortlist for the first time.
