What changed

The primary source's structured 'End date' fields for the three ADOPTION_WORKFLOW proposals (MRV simplification regulation, heat/fuel benchmark regulation, and the competitiveness/cost-effective decarbonisation directive) now all read '2026/10/30 23:59:59,' one calendar day later than the 29 October 2026 deadline previously recorded for these same three feedback periods. The feedback period length remains 8 weeks and feedback status remains OPEN for all three; the earlier planning-workflow milestones (call for evidence and open public consultation, both closed 8 July 2025) are unchanged in this source.

Why it matters

As with the prior correction from 28 to 29 October, this further shift to 30 October does not touch the substance of the ETS1/MSR review, but it means the common feedback cut-off for the three linked instruments has now moved twice in the tracked record. Because the MRV simplification regulation, benchmark regulation, and competitiveness directive are procedurally linked and expected to move together toward ordinary legislative procedure, an accurate common deadline remains a prerequisite for downstream tracking of Parliament/Council engagement, where MSR parameters and free-allocation benchmarks are typically contested.

MD analysis

The recurrence of an off-by-one-type discrepancy (28→29→30 October) across successive extractions of the same underlying source field suggests either an unstable or ambiguous end-date representation in the Commission's Have Your Say portal (e.g., inclusive/exclusive day-counting against the 20/25 August 2026 publication dates plus an 8-week feedback period) rather than a genuine Commission decision to extend the consultation window. Absent an explicit Commission statement confirming an extension, this should continue to be treated as a data-precision issue rather than a substantive procedural development. No new information is available on the content of the three proposals themselves.
