Cleantech Taxonomy — Architecture Overview
OrigoCleantech Taxonomy — Architecture Overview
The OrigoCleantech 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
| Book | Source | Role | License | Last Updated |
|---|---|---|---|---|
| Book 01 | CPI Global Landscape of Climate Finance 2025 | Structural backbone — 9 sectors, ~150 nodes | CC BY-NC-SA 4.0 | July 2025 |
| Book 02 | EU Taxonomy for Sustainable Activities 2026 | Regulatory standard — binding EU law, DNSH criteria | Open (EU law) | March 2026 revision |
| Book 03 | IEA Energy Technology Classification System 2025 | Energy depth — critical minerals + industrial electrification added | Open (IEA) | 2025 |
| Book 04 | Climate Bonds Initiative Taxonomy | Finance eligibility — 50+ national taxonomies incl. LATAM | © CBI | Ongoing |
