A curated collection of climate risk models for real estate. Browse 109 models across transition risk, physical risk, carbon accounting, energy performance, embodied carbon, and more. For 22 of them we provide a harmonized API wrapper so you can chain queries across engines.
- 109 models with verified metadata — author, license, scope, limitations, citations
- 22 live engines with a harmonized API: upload CSV, get results, chain queries across models
- Interactive Try It tab: drop a CSV, see a real-time processing console, download results
- 4 views: gallery cards, sortable list, interactive world map, complexity/maturity scatter plot
- Filtering: category, lifecycle phase, license, region, status, tags — all URL-synced and shareable
- Zero dependencies: vanilla JS, no build step, runs from a static file server

Each engine exposes the same interface:
await engine.init(); // Load reference data
const result = await engine.calculate(row); // Process one row
const rows = engine.parseCSV(csvText); // Parse CSV input
const csv = engine.generateTemplate(); // Get CSV template (optional)
const errors = engine.validate(row); // Validate input (optional)Upload a CSV in the Try It tab, watch the processing console, and download results as CSV. Engines that call external APIs (BAFU CO2, geo.admin.ch, etc.) run async; local engines (CRREM) run instantly.
