Climate Impact

Halcyon defines and evaluates ventures based on their measurable impact in climate adaptation, which refers to meaningful adjustments in ecological, social, or economic systems made in response to actual or expected climate impacts. These adjustments aim to reduce vulnerability and build resilience by increasing access to climate adaptation interventions, such as improved infrastructure, access to early warning systems, resilient agriculture practices, water management solutions, and more.
