OS-Climate

OS-Climate is an open-source initiative under FINOS that provides data, analytics, and collaboration platforms to support climate-related financial risk analysis and climate-aligned decision-making for financial institutions and other enterprises.

  • Open-source data and analytics platform for climate-related financial decision support (data and analytics platform).
  • Shared climate data commons for curated, standardized climate, economic, and financial datasets (data management).
  • Tools and models for physical climate risk and transition risk assessment (risk analytics).
  • Collaborative environment for financial institutions, NGOs, and technology providers to co-develop climate finance tools (collaboration framework).
  • Hosted under the Fintech Open Source Foundation (FINOS) with governance, open collaboration, and community contributions (open-source foundation project).

More About OS-Climate

OS-Climate is an open-source project hosted by the Fintech Open Source Foundation (FINOS) that focuses on building data and analytics infrastructure to support climate-related financial risk assessment and climate-aligned decision-making by financial institutions, corporates, and public-sector entities (climate finance analytics platform).

The project centers on creating a shared climate data commons that aggregates, curates, and standardizes climate, economic, and financial datasets from multiple sources (data management). This data environment is designed to support interoperability between models and tools and to reduce duplication of data engineering efforts across institutions. By providing a common data layer, OS-Climate enables users to run climate scenario analysis, physical risk evaluation, and transition risk assessment with consistent data foundations (risk analytics).

OS-Climate also supports open development of analytics tools, models, and workflows for use cases such as portfolio alignment with climate goals, sectoral transition analysis, and infrastructure or asset-level physical risk assessment (financial risk analytics). These tools are developed collaboratively by member firms and contributors and are intended to run on top of the shared data environment, so that models can be reused, inspected, and adapted for different institutional contexts (analytics frameworks).

Enterprises use OS-Climate by integrating its open datasets, models, and code into internal risk, reporting, and investment analysis workflows (enterprise integration). Financial institutions can deploy OS-Climate components within their own data platforms or cloud environments, connect them to internal data sources, and incorporate climate metrics into processes such as credit risk assessment, portfolio management, and regulatory or voluntary climate disclosures (risk and compliance support).

From an architectural perspective, OS-Climate is positioned as an open-source layer in the climate-finance technology stack, alongside proprietary systems, internal data warehouses, and regulatory reporting pipelines (platform architecture). It focuses on interoperability and extensibility, encouraging contributions of new datasets, taxonomies, and models that can be shared under open licenses (open collaboration). Its governance under FINOS provides structures for contribution, IP management, and technical steering aligned with existing open-source and financial industry practices (open-source governance).

In an enterprise technical taxonomy, OS-Climate fits into categories such as climate risk analytics platforms, Environmental Social and Governance (ESG) and sustainability data infrastructure, and open collaboration frameworks for financial services (enterprise analytics platform). It serves as a foundational resource for institutions seeking to incorporate climate data and analytics into finance, investment, and risk processes using open, transparent, and reusable tools.
