Open-source tools play a critical role in advancing equitable access to climate risk analysis. By removing cost barriers and offering transparent, adaptable solutions, they enable decision-makers at all levels to better understand and manage climate risks. These tools support locally relevant solutions by allowing users to integrate community-specific data, customize hazard thresholds, and build on existing analytical frameworks.

We at MCII, promote the development, adaptation, and use of open-source tools to ensure that climate analytics are widely accessible and practically applicable. This includes publishing code, sharing data, and developing training resources that help users understand and apply complex models in real-world contexts. When possible, existing open platforms are used and strengthened, while original tools and documentation are made available to support replication and innovation.

By fostering openness, we help build long-term capacity for risk-informed planning and action. Open-source tools also encourage collaboration across disciplines and geographies, accelerating the exchange of knowledge and technical improvements. Through this work, we support a broader shift toward transparency, inclusivity, and sustainability in climate decision-making.
