Regulation has made measurement mandatory.
Regulation (EU) 2024/1787 on the reduction of methane emissions in the energy sector entered into force on 4 August 2024.[4] What follows is a summary of the obligations that matter for measurement, as set out in the Vemissure business concept note.

20244 August — entry into force
Regulation (EU) 2024/1787 enters into force, establishing the framework and the sequence of obligations that follow.[4]
20255 May — LDAR programmes and importer information
Leak-detection-and-repair programmes and importer information were due. Detection activity rises across the sector — a large part of why detection alone stops being a differentiator.[5]
20265 February — routine flaring and venting prohibited
Routine flaring and venting has been prohibited since this date, changing operational practice and the emission profile a site is expected to be able to demonstrate.[5]
2027The pivotal year — Article 12(3) and Article 28
From 5 February 2027, Article 12(3) requires operators to reconcile source-level inventories against site-level measurements for operated assets. From 1 January 2027, Article 28 requires importers to demonstrate MRV-equivalence.[4][5]
This is the requirement Vemissure is built around. Reconciliation is a comparison of two uncertain quantities; unless both carry honest uncertainty, "the numbers disagree" cannot be separated from "the numbers are within measurement noise".
20285 August — non-operated assets and methane intensity
Article 12(3) reconciliation extends to non-operated assets, and Article 29 adds methane-intensity reporting. Non-operated assets are precisely where an operator has least visibility and most need of an independent measurement constraint.[5]
20305 August — Article 30 maximum intensity values
Maximum methane-intensity values apply, with penalties reaching 20% of turnover.[5] When a figure sits near a threshold with that consequence attached, the width and honesty of its uncertainty interval stops being academic.
202620 July — Commission Recommendations C/2026/5172 and C/2026/5176
These set out transitional application with a three-year penalty grace period and, separately, a defined independent-certification route.[18] The net effect is a slower but more durable market — and a certification channel that did not formally exist before.
The consequence
Why this creates a new measurement requirement.
Reconciliation needs two honest intervals
Article 12(3) compares an inventory with a measurement. If either interval is unknown or misstated, no defensible conclusion follows — and the operator ends up arguing about the measurement rather than the emissions.
Thresholds make interval width material
Once Article 30 maximum intensity values apply, with penalties reaching 20% of turnover, the distance between an estimate and a threshold must be assessed against a credible interval rather than a nominal one.
Assurance needs reproducibility
A figure that cannot be regenerated cannot be tested. As reporting moves toward accredited verification under ISO/IEC 17029, reproducibility becomes a practical requirement rather than good practice.[22]
Vemissure's position
Vemissure is not a regulated entity and holds no licence, permit or accreditation requirement of its own. It does not determine whether an entity meets a regulatory requirement. It is being built to supply the measurement basis and evidence that operators and their verifiers need in order to make and support that determination themselves.
UK context
The UK has its own Methane Action Plan;[11] the North Sea Transition Authority drives offshore methane and flaring reduction;[12] and a House of Lords committee has urged the UK to keep up momentum on methane.[13] Combined with UK metrology capability and an established accredited-verifier community, that gives a genuine domestic beachhead.
