Source Alignment Map

How the Four Sources Align

Each Cleantech Taxonomy sector draws from multiple upstream sources. This map shows where sources overlap, where they diverge, and where CTH extensions fill gaps none of them cover.

Sector-by-Sector Alignment

Energy Systems (ES)

CPI GLCFEU TaxonomyIEA ETCSCBICTH Extensions
Energy Systems sector — renewable generation, grids, storage, fossil fuel transitionClimate Mitigation: Energy (generation, transmission, storage)Energy Supply + Cross-Cutting (full technology-level depth)Energy sector criteria (solar, wind, geothermal, bioenergy, storage)CT-EX-010 Pico-solar, CT-EX-012 Artisanal cleantech, CT-EX-013 Productive energy use

Convergence: All 4 sources cover core renewables (solar, wind, hydro, geothermal, biomass). IEA provides deepest technology-level granularity. CBI adds bond eligibility criteria. Gap: None of the 4 sources adequately cover off-grid/informal economy energy access — CTH fills this with 3 extension nodes.

Transport (TR)

CPI GLCFEU TaxonomyIEA ETCSCBICTH Extensions
Transport sector — road, rail, maritime, aviationClimate Mitigation: Transport activitiesEnd-Use: Transport (EVs, H2 vehicles, fuel cells)Transport criteria (rail, EVs, maritime, cycling)None — adequately covered

Convergence: Strong overlap across all 4 sources on EVs, rail, and modal shift. Gap: Micro-mobility (e-bikes, 3-wheelers) covered by CBI but underrepresented in CPI and IEA.

Buildings & Infrastructure (BU)

CPI GLCFEU TaxonomyIEA ETCSCBICTH Extensions
Buildings & Infrastructure sectorClimate Mitigation: Buildings (new + renovation)End-Use: Buildings (heat pumps, efficiency)Buildings criteria (efficiency, certification)None — adequately covered

Convergence: All 4 cover energy efficiency and green construction. EU Taxonomy most prescriptive (TSC thresholds). Gap: Affordable/social green housing only in CBI; transport infrastructure sits between BU and TR sectors.

Industry (IN)

CPI GLCFEU TaxonomyIEA ETCSCBICTH Extensions
Industry sector — manufacturing, heavy industry, hydrogenClimate Mitigation: ManufacturingEnd-Use: Industry (electrification, H2, CCS) + Critical MineralsIndustry criteria (cement, steel, chemicals)None — adequately covered

Convergence: Hard-to-abate (steel, cement, chemicals) covered by all. IEA adds critical minerals depth. Gap: Light manufacturing in LATAM context not well covered by any source.

AFOLU (AF)

CPI GLCFEU TaxonomyIEA ETCSCBICTH Extensions
AFOLU sector — agriculture, forestry, land use, fisheriesClimate Mitigation: Forestry & environmental protection; Biodiversity objectiveN/A (energy-focused)Land Use, Marine Resources & BiodiversityCT-EX-001 to CT-EX-009 (adaptation, NbS, bioeconomy) + CT-EX-018 to CT-EX-021 (EUDR supply chain)

Convergence: CPI, EU Taxonomy, and CBI all cover forestry/reforestation. Major gap: IEA has zero AFOLU coverage. None of the 4 sources cover smallholder adaptation, community reforestation, silvopastoral systems, PES platforms, or EUDR compliance services — CTH fills this with 13 extension nodes, the largest gap category.

Waste (WA)

CPI GLCFEU TaxonomyIEA ETCSCBICTH Extensions

Cleantech Taxonomy Synthesis Methodology

How the Cleantech Taxonomy Is Built

The Cleantech Taxonomy is a synthesis product — it does not replicate any single upstream source but combines structural elements from four institutional sources into a unified classification schema for LATAM climate innovation.

Synthesis Process

Step 1: Structural Backbone (CPI)

CPI's Global Landscape of Climate Finance provides the primary sector structure. Its 9 sectors organize all Cleantech Taxonomy nodes at the top level. CPI was chosen because:

Step 2: Regulatory Crosswalk (EU Taxonomy)

Each node is crosswalked to the EU Taxonomy's Climate Delegated Act activities. This provides:

Step 3: Energy Depth (IEA)

For Energy Systems, Transport, and Industry nodes, the IEA ETCS provides technology-level classification:

IEA alignment is marked N/A for non-energy sectors (AFOLU, Waste, Water, ICT).

Step 4: Finance Eligibility (CBI)

CBI sector criteria determine bond certification eligibility. This layer connects the taxonomy to green bond markets and provides:

Step 5: LATAM Gap Extensions (CTH)

21 extension nodes (CT-EX-001 to CT-EX-021) fill gaps none of the 4 upstream sources cover:

Step 6: Regulatory Anchoring (Colombian Frameworks)

All 71 nodes are crosswalked to 6 Colombian regulatory frameworks:

Defensibility

Every Cleantech Taxonomy node traces back to at least one authoritative source. The Source Alignment Map documents exactly which sources inform each node. CTH extensions are explicitly labelled as original work (CC BY 4.0) and tagged with source=CTH v0.1 extension.

Update Protocol

When an upstream source publishes a new version (detected by the monthly watcher), the update follows this protocol:

  1. Watcher posts a Watch Report to Book 00
  2. CTH reviews the changes and drafts amendments
  3. Gideon approves amendments (HITL gate)
  4. New Cleantech Taxonomy minor version published (v1.1, v1.2, etc.)
  5. Master Index JSON and filtered views updated
  6. Version release note posted + agents/apps notified

Annual editorial review is timed to COP season (October-December).

Divergence Map — Where CTH Extensions Go Beyond Sources

Purpose

This page documents every area where the Cleantech Taxonomy diverges from or extends beyond its four upstream sources. Divergence is explicitly labelled — no CTH extension is presented as sourced from CPI, EU Taxonomy, IEA, or CBI.

Gap Categories

1. Adaptation Technologies (CT-EX-001 to CT-EX-004)

Why upstream sources miss this: CPI tracks adaptation finance flows but does not classify adaptation technologies. EU Taxonomy has an adaptation objective but focuses on infrastructure resilience, not crop-level adaptation. IEA is energy-only. CBI has a Resilience Taxonomy but it covers physical asset resilience, not agricultural adaptation.

What CTH adds: Four nodes covering the practical adaptation technologies that LATAM smallholders need — drought-resistant crop varieties, nature-based flood resilience, shade-grown heat adaptation systems, and early warning systems for climate events.

LATAM relevance: Critical. Climate adaptation in tropical agriculture is the most immediate need for Colombia's 500,000+ coffee farming families.

2. Nature-Based Solutions & Bioeconomy (CT-EX-005 to CT-EX-009)

Why upstream sources miss this: CPI covers "AFOLU" broadly. EU Taxonomy includes forestry activities. But none of the 4 sources classify community-managed NbS, PES platforms, non-timber forest product value chains, or silvopastoral systems as distinct technology/activity categories.

What CTH adds: Five nodes that represent core LATAM climate strategies — community reforestation, mangrove/blue carbon, silvopastoral systems (a flagship Colombia GF Taxonomy activity), NTFP bioeconomy, and PES platforms (pioneered by Costa Rica).

LATAM relevance: These are not marginal activities — silvopastoral systems alone are a USD 100M+ annual investment category in Colombia via Fedegán and the Green Finance Taxonomy.

3. Small-Scale & Informal Economy Cleantech (CT-EX-010 to CT-EX-013)

Why upstream sources miss this: All 4 upstream sources are designed for institutional/commercial scale. CPI tracks flows above USD 1M. EU Taxonomy targets reporting entities. IEA classifies industrial technologies. CBI certifies bonds. None of them classify the sub-1kW, sub-USD-500 clean energy solutions that serve LATAM's informal economy.

What CTH adds: Four nodes for pico-solar, community biodigesters, artisanal cleantech (solar drying, clean cookstoves), and productive energy use for microenterprises.

LATAM relevance: The majority of LATAM climate impact occurs at the smallholder and informal economy level. Excluding these technologies from a taxonomy means excluding the people who need climate solutions most.

4. AI-for-Climate & MRV Enabling Technologies (CT-EX-014 to CT-EX-017)

Why upstream sources miss this: CPI tracks digital finance. EU Taxonomy has ICT activities. But satellite deforestation monitoring, AI-powered MRV, supply chain traceability platforms, and precision agriculture data platforms are not classified as distinct categories by any of the 4 sources — they sit in the gap between ICT and compliance infrastructure.

What CTH adds: Four nodes covering the technology stack that makes EUDR compliance operational and enables carbon MRV for LATAM supply chains.

5. EUDR Supply Chain Services (CT-EX-018 to CT-EX-021)

Why upstream sources miss this: The EUDR (Regulation (EU) 2023/1115) is a market access regulation, not a sustainability taxonomy. None of the 4 upstream sources classify the service layer that makes EUDR compliance work — certification services, due diligence platforms, smallholder technical assistance, and operator documentation services.

What CTH adds: Four nodes covering the EUDR compliance service ecosystem. These are the nodes most directly relevant to CTH's commercial products (Data Boathouse).
