Climate Tech Startup Grants 2026 provide funding opportunities for innovative companies, social enterprises, and organizations developing solutions to combat climate change. These grants support climate adaptation technologies, renewable solutions, climate-smart agriculture, disaster resilience, water management, food security innovations, and other technologies helping communities respond to environmental challenges.

Background & Grant Opportunity Description

Climate Tech Startup Grants 2026 offer opportunities for startups and innovation-driven organizations developing solutions that address climate change challenges. As extreme weather events, environmental degradation, and climate risks continue affecting communities worldwide, funding programmes are increasingly supporting companies creating practical climate solutions.

One example is the Adaptation Fund Climate Innovation Accelerator (AFCIA), which supports organizations developing innovative solutions that strengthen climate resilience and food security. The programme supports both low-tech and high-tech innovations designed to help vulnerable communities adapt to climate change.

The initiative is implemented by the World Food Programme (WFP) in partnership with the Adaptation Fund and focuses on scaling impactful climate innovations.

Climate technology startups working in areas such as clean energy, climate data, agricultural technology, environmental monitoring, and resilience solutions can benefit from these funding opportunities.
