# Cleantech Taxonomy — Architecture Overview

 The Cleantech Taxonomy is CleantechHUB's climate technology classification schema for LATAM. It is built on four actively maintained upstream sources and extended with LATAM-specific nodes.

## Four-Source Backbone

## ID System

 Format: `OT-[SECTOR_CODE]-[3-digit sequence]`  
 Example: `CT-AF-001` = AFOLU sector, node 001  
 Extension IDs: `CT-EX-001` through `CT-EX-021` (LATAM gap extensions)
