Scope. Projects should develop and demonstrate innovative solutions that reduce the impacts of extreme heat, rising temperatures and climate-induced weather events. Proposals may focus on cooling technologies, adaptation measures, nature-based climate resilience or solutions that protect people, infrastructure, food systems and ecosystems from climate risks. Solutions should demonstrate proof of concept, potential for measurable impact and a credible pathway to commercial deployment or replication across Southeast Asia.
Sectors. Urban cooling, outdoor cooling systems and heat-resilient public spaces. Passive cooling technologies, reflective surfaces, cool roofs and innovative building materials. Nature-based solutions, urban greening and ecosystem restoration. Coastal resilience, mangrove restoration, seaweed cultivation and blue-green infrastructure. Heat-health technologies and solutions for vulnerable populations and outdoor workers. Climate-resilient agriculture, food systems and regenerative land management. Climate adaptation, heat monitoring and resilient urban infrastructure.
Eligible applicants. Applicants aged 18 or older from anywhere in the world may apply, subject to the official eligibility and conflict-of-interest conditions. Solutions must have achieved proof of concept, generally corresponding to TRL 6 or above, and demonstrate applicability to Southeast Asia.
Key requirements. Projects should: address a clearly identified climate adaptation, extreme heat or resilience challenge; demonstrate a credible technological or nature-based solution with measurable benefits; protect communities, vulnerable groups, infrastructure or ecosystems against heat and other climate-related impacts; demonstrate scalability, commercial viability or a sustainable implementation model; provide a credible pathway towards real-world piloting in Singapore or Southeast Asia, as appropriate to the solution[; explain the expected environmental and social benefits, implementation plan and potential for wider deployment.
Funding & duration. The three Grand Winners across all challenge themes will each receive S$1 million in grant funding. Cool Earth is one of the three themes eligible for this award. The overall funding pool exceeds S$5.5 million, including other development funding and investment opportunities across the challenge. There is no fixed project duration specified in the general challenge information.
