Today we are proud to announce that the Ecosystem Integrity Index (EII) is now open source! This release includes: ▸ Global coverage at 300m resolution ▸ Current-state mapping ▸ Python API for easy data access ▸ Google Earth Engine integration for scalable analysis The challenge of measuring ecosystem health at scale has long constrained nature-based finance. While we have robust data on ecological pressures and species responses, a unified, scalable and publicly available metric for ecosystem condition has been missing. Our implementation builds on the pioneering conceptual framework originated by UNEP-WCMC and featured in Taskforce on Nature-related Financial Disclosures (TNFD) and the Nature Positive Initiative. This release enables: ▸ Portfolio assessment at scale: Financial institutions can screen thousands of assets for nature-related risk without requiring site visits or bespoke data collection for every location. ▸ Quantitative target setting: Corporations and land stewards can define clear, measurable goals for nature stewardship and track progress over time with a consistent metric. ▸ Verification of nature-based solutions: Investors can underwrite projects with confidence, knowing they are delivering real ecological improvements rather than greenwashing. ▸ Solving the actionability gap: Global models often fail to register local improvements made by land stewards. The EII bridges this gap by allowing plot-level data (soil health, water retention, habitat area) to modulate landscape-scale scores, maintaining global consistency while rewarding verified on-the-ground action. How it works: The EII synthesizes three dimensions at 300-meter resolution: functional integrity (actual productivity vs potential), structural integrity (habitat configuration), and compositional integrity (species composition). These combine through a limiting factor principle inspired by Liebig's Law, ensuring no single strength can mask critical weaknesses. A local modulation framework allows plot-level KPIs to refine landscape-scale baselines, maintaining global consistency while rewarding verified on-the-ground improvements. The framework updates continuously as Earth observation and biodiversity monitoring capabilities advance.
