How they approach the work
Named approaches extracted from this org’s sources. Where others share an approach, follow it to see the full set of orgs running it.
- Art-Science Integration for Public Engagementmethodology: art-science-integrationBy integrating art and creative disciplines with climate science, the organization fosters emotional engagement and public understanding because narrative and aesthetic experiences make complex climate solutions more accessible and relatable.
- Cross-Sector Collaboration Networkmethodology: cross-sector_collaborationBy uniting public, private, academic, and creative sectors around shared climate goals, the organization amplifies impact because diverse expertise and resources overcome institutional silos that otherwise limit innovation scale and speed.
- Knowledge-to-Action Hubmethodology: knowledge-to-actionBy leveraging institutional knowledge and competencies, the organization generates and disseminates actionable policy guidance, financing strategies, and scalable instruments because centralized expertise lowers adoption barriers for climate investment.
- Living Laboratory Modelmethodology: living-laboratoryBy using the Governors Island campus as a real-world testing ground, the organization accelerates the development and deployment of scalable urban climate solutions because experiential validation in authentic urban environments increases readiness for broader adoption.
- Research-to-Deployment Bridgemethodology: research-to-deployment bridgeBy connecting early-stage climate innovators—especially those emerging from universities—with funding, mentorship, and piloting opportunities, the organization enables the transition from concept to commercially viable solutions because structured support reduces barriers to real-world implementation.
