What OS-C does

OS-Climate Resources is a non-profit, open-source initiative operating under the governance of FINOS and the Linux Foundation, founded in 2018 and headquartered in New York. It builds Python-based climate risk analytics tools for the financial services sector, with a primary user base of banks, asset managers, insurers, and technology partners that participate as organizational members. Its core product suite includes physrisk, an open-source library for physical climate risk modeling; the Data Commons Platform, which aggregates climate, physical-risk, and asset-reference datasets with infrastructure contributions from Red Hat; InferESG, an AI-assisted ESG disclosure tool co-developed with abrdn; and the CDM (Climate Data Model), which in 2024 was extended to support property collateral use cases.

The organization's technology architecture is centered on shared Python libraries and open data infrastructure rather than a commercial SaaS stack. Engagement is driven through open-source contribution workflows, foundation-hosted events across New York, London, Toronto, and Paris, and partnerships with bodies such as EFRAG for alignment with European sustainability reporting standards and Scott Logic Ltd for engineering delivery. Participation from major financial institutions positions the platform as a neutral, industry-wide reference implementation for climate risk analytics.

The business model is non-commercial: the software is provided free of charge under open-source licenses, and the organization is funded through organizational membership fees and direct contributions from participating financial institutions and technology partners. There is no product pricing, no per-seat licensing, and no disclosed revenue. Growth in operating capacity is therefore a function of membership recruitment and contributed engineering rather than commercial sales execution.

Core offering

OS-Climate maintains open-source tools and reference implementations that accelerate climate risk analytics and reporting capabilities for financial institutions. Its core offerings are the PhysRisk open-source Python library for physical climate risk analysis (with hazard indicator derivation, reference API, and UI components) and the Data Commons Platform for sharing and creating reviewed climate-related datasets. Together, these tools help financial institutions identify, quantify, and manage climate-related financial risks such as physical risk on property assets.

Product overview

OS-Climate is a Linux Foundation/FINOS open-source initiative providing a portfolio of climate risk analytics tools for financial institutions. The core offerings consist of physrisk (an open-source Python library for physical climate risk analysis with hazard indicators) and the Data Commons Platform (a data sharing platform for climate-related datasets). These components work together to help users identify, quantify, and manage climate-related financial risks. Participation is open and non-discriminatory under FINOS/Linux Foundation governance.

Emerging players

• Persefoni: Climate management and carbon accounting platform serving financial institutions and large enterprises. Comparable on the climate data infrastructure and reporting side, though Persefoni focuses on carbon accounting whereas OS-Climate emphasizes physical risk and open-source data sharing.
• Watershed: Enterprise carbon accounting and climate platform with finance-sector customers. Adjacent to OS-Climate on climate data and corporate reporting, but focuses on carbon/GHG accounting rather than physical hazard modeling.
• Cervest: AI-powered climate risk analytics platform for asset-level physical and transition risk. Directly comparable to OS-Climate's PhysRisk on physical hazard exposure analytics but offered as commercial SaaS rather than open source.
• Riskthinking.AI: Climate risk analytics platform focused on financial institutions with physical and transition risk modeling. Comparable to OS-Climate's PhysRisk offering in customer base and analytical approach, but delivered as a commercial subscription product.

Direct peers

• Climate X (now MI Climate X): Specializes in physical climate risk modeling and asset-level exposure analytics for banks, asset managers, and real estate. Highly comparable in product surface to OS-Climate's PhysRisk and Data Commons, addressing the same financial-institution buyer with property hazard analytics.
• Jupiter Intelligence: Commercial provider of physical climate risk analytics for financial institutions and infrastructure operators. Directly comparable to OS-Climate's PhysRisk library in offering asset-level hazard exposure and loss modeling, though delivered as a paid enterprise platform rather than open source.

Broad incumbents

• MSCI ESG Research: Large incumbent offering ESG ratings, climate data, and portfolio analytics to global financial institutions. Overlaps with OS-Climate's broader climate-aligned investing and TCFD/IFRS reporting focus but operates as a commercial subscription business across a wider data portfolio.
• Ortec Finance: Provides scenario analysis and climate risk modeling tools for pension funds, insurers, and asset managers. Comparable to OS-Climate's transition/physical risk analytics for portfolio-level climate stress testing and long-horizon scenario work.
• Munich Re / Munich Re Risk Solutions: Major reinsurer with NatCatSERVICE and climate risk analytics offerings for insurance and capital markets clients. Comparable on the physical hazard modeling side, particularly for parametric and accumulation risk, which overlaps with OS-Climate's PhysRisk scope.
• S&P Global Trucost: Provides carbon, climate, and ESG data and analytics for investors and corporates. Comparable to OS-Climate on the data and disclosure analytics side (TCFD/CSRD-aligned reporting), though delivered via a commercial data vendor model with broader environmental coverage.
