gateEUTaxonomy — Greenwashing Prevention Gate
// IMMO.QUICK · GATEEUTAXONOMY · VO (EU) 2020/852 · SFDR ART. 8/9

No declaration, without DNSH consistency.

gateEUTaxonomy forensically seals that an Article 8/9 declaration passes six clusters, substantial contribution, DNSH assessment, minimum safeguards, SFDR alignment, CSRD alignment, and technical screening criteria, before greenwashing could occur at T=0. Support for asset managers, never a replacement for a regulator's own recognition as evidence.

In one sentence: gateEUTaxonomy checks every taxonomy qualification against all six environmental objectives, before the fund declares its alignment percentage.
✓ RELEVANT IF...
  • You distribute Article 8/9 SFDR products with taxonomy qualification
  • You need to prove DNSH consistency across all six environmental objectives
✕ NOT RELEVANT IF...
  • You expect a regulator to automatically recognise the result as taxonomy certification
  • No Article 8/9 product or taxonomy qualification is involved
// The problem

80 percent taxonomy alignment without a DNSH check is greenwashing, not sustainability.

The Taxonomy Regulation requires each economic activity to make a substantial contribution to one of six environmental objectives while doing no significant harm to the other five. gateEUTaxonomy checks this consistency before every declaration.

CSRD alignment as the linking fifth cluster
Taxonomy declarations must align with sustainability reporting under CSRD/ESRS. The gate checks this alignment, rather than leaving it to separate departments.
// Architecture

6 clusters, checked sequentially.

Every cluster is dispositive (material_block_mode: true), a hit blocks bindingly, not merely for documentation.

CLUSTER 1
Substantial Contribution
Checks the qualification of the economic activity under Taxonomy Regulation Art. 3.

CLUSTER 2
DNSH Assessment
Checks Do No Significant Harm against all six environmental objectives under Art. 17.
dnsh_assessment_hash
CLUSTER 3
Minimum Safeguards
Checks OECD Guidelines, UN Guiding Principles, and ILO core conventions under Art. 18.
minimum_safeguards_hash
CLUSTER 4
SFDR Alignment
Checks the Article 8/9 declaration and the PAI disclosure under SFDR Art. 8/9.
sfdr_alignment_hash
CLUSTER 5
CSRD Alignment
Checks alignment with ESRS sustainability reporting.

CLUSTER 6
Technical Screening Criteria (TSC)
Checks the activity-specific technical screening criteria under Art. 10 to 15.

No case, no doubt
Every cluster returns its own sealed result. A single hit in an active cluster is enough to block the overall action.
// Test results

// Clarification

What gateEUTaxonomy is not.

  • Not automatic recognition by ESMA or a national regulator. The gate delivers a cryptographic proof, not taxonomy certification.
  • Not a replacement for external assurance of sustainability reporting. The gate seals the pre-declaration check.

For asset managers that want to make taxonomy declarations provable.
