When a Threshold Changes Sign: Multilingual Legal Certainty and the Issuance of EU Carbon-Removal Units

European Union carbon-removal certification makes verified physical outcomes contingent on rules governing certified units. Section 2.3.6 of Commission Delegated Regulation (EU) 2026/285 prohibits unit generation in Spanish when total uncertainty is below 20 per cent; its English text prohibits issuance when uncertainty is above that threshold. This contradiction is textual, not evidence of erroneous units. The essay examines the tension between multilingual interpretation, legal certainty, CRCF certification procedures and existing remedies. It proposes a reproducible decision-equivalence check as a specific use of established preventive safeguards, not a new institution or legal duty. The check flags conflicting literal outcomes for qualified legal review before a scheme incorporates a disputed rule into operational instructions.
