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 GLCF
EU Taxonomy
IEA ETCS
CBI
CTH Extensions
Energy Systems sector — renewable generation, grids, storage, fossil fuel transition
Climate 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 GLCF
EU Taxonomy
IEA ETCS
CBI
CTH Extensions
Transport sector — road, rail, maritime, aviation
Climate Mitigation: Transport activities
End-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 GLCF
EU Taxonomy
IEA ETCS
CBI
CTH Extensions
Buildings & Infrastructure sector
Climate 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 GLCF
EU Taxonomy
IEA ETCS
CBI
CTH Extensions
Industry sector — manufacturing, heavy industry, hydrogen
Climate Mitigation: Manufacturing
End-Use: Industry (electrification, H2, CCS) + Critical Minerals
Industry 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 GLCF
EU Taxonomy
IEA ETCS
CBI
CTH Extensions
AFOLU sector — agriculture, forestry, land use, fisheries
Climate Mitigation: Forestry & environmental protection; Biodiversity objective
N/A (energy-focused)
Land Use, Marine Resources & Biodiversity
CT-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 GLCF
EU Taxonomy
IEA ETCS
CBI
CTH Extensions
Waste sector
Climate Mitigation: Water, Sewerage & Waste; Circular Economy objective
N/A
Waste & Pollution Control
None
Water & Wastewater (WW)
CPI GLCF
EU Taxonomy
IEA ETCS
CBI
CTH Extensions
Water & Wastewater sector
Water & Marine Resources objective
N/A
Water criteria (treatment, efficiency, flood resilience)
None
ICT & Cross-Sectoral (IC, XS)
CPI GLCF
EU Taxonomy
IEA ETCS
CBI
CTH Extensions
ICT & Digitalization + Cross-sectoral
ICT activities (Climate Mitigation)
Cross-Cutting Technologies (smart grids, digitalization)
N/A (no ICT criteria)
CT-EX-014 to CT-EX-017 (satellite monitoring, AI MRV, traceability, precision ag data)
Gap: Carbon markets and climate finance platforms not covered by any of the 4 sources as technology categories. CTH adds 4 AI/MRV extensions.
