The Liveability Challenge 2026 drew over 1,500 submissions across 100 countries, with eight stand-out solutions shortlisted after a rigorous selection process. Image: Eco-Business. Eight high impact start-ups have been shortlisted in The Liveability Challenge (TLC) – a global crowdsourcing platform presented by Temasek Foundation and organised by Eco-Business. Chosen from a record 1,500 submissions across 100 countries, the finalists represent the cutting-edge innovations addressing urgent sustainable development challenges in the urban tropics. These disruptive and technology-driven solutions in the two chosen themes for the year – Decarbonisation and Cool Earth – range from closed-loop systems that reduce buildings’ cooling energy use to advanced textile recycling with significant reductions in energy, water and emissions, and next-generation carbon capture and hydrogen production systems. The 8 finalists for The Liveability Challenge 2026 are: Endo Enterprises (United Kingdom) Closed-loop hydronic additive for the built environment that reduces energy for cooling by up to 15%. FlueVault (Singapore) Low cost, low-purity industrial CO2 capture and storage with critical metal recovery. MacroCycleTechnologies (United States of America) Textile-to-textile polyester recycling technology with 80% lower energy usage, 80% lower CO2 emissions and 99% less water usage, all at price parity. Metha8 (Singapore) Methanol-to-power technology for 24/7 baseload generation with 60% efficiency and integrated CO₂ capture. Power To Hydrogen (United States of America) Low-cost hydrogen production system with five times greater durability, 65% lower capex and a pathway to US$2/kg of hydrogen. SPACECOOL (Japan) Passive radiative cooling that cuts energy use by up to 11% and reduces urban heat island effects. UP Catalyst (Estonia) Utilisation of flue gas to produce battery-grade carbon materials at 26% lower cost than conventional methods. YAMA (France) Electrified carbon capture technology for dilute gas-fired streams, delivering up to 50% lower costs than conventional methods while enabling flexible operation. Two finalists will each receive S$1 million in catalytic grant funding at The Liveability Challenge 2026 Grand Finale, which will be held on 20 May 2026 at Marina Bay Sands Expo and Convention Centre – a flagship partner event of Ecosperity Week 2026 by Temasek. In addition, A*STAR has committed up to S$2 million annually over the next three years to support TLC, marking the platform’s largest funding injection to date, with […]
