The Global Innovation Lab for Climate Finance, an investor-led public-private initiative, invites applications to its Call for Ideas, seeking innovative financial vehicles designed to mobilize private capital for climate mitigation and adaptation in developing countries. Rather than funding projects directly, the Lab provides selected teams with roughly seven months of technical assistance, investor engagement, and go-to-market support worth over US$250,000, aimed at developing and launching the vehicle itself. Applicants must be cohesive teams with a proven track record in deploying capital or climate solutions, targeting implementation in ODA-eligible countries, with a specific focus this cycle on Africa, Asia-Pacific, Brazil, India, or Latin America and the Caribbean. Preliminary applications are due 18 October 2026. Call for Ideas
